Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations. This powerful hormone is part of the human body's acute stress response system, also called the "fight or flight" response. It works by stimulating the heart rate, contracting blood vessels, and dilating air passages, all of which work to increase blood flow to the muscles and oxygen to the lungs. Additionally, it is used as a medical treatment for some potentially life-threatening conditions including anaphylactic shock. In the US, the medical community largely refers to this hormone as epinephrine, although the two terms may be used interchangeably.

The Adrenal Glands

The adrenal glands are found directly above the kidneys in the human body, and are roughly 3 inches (7.62 cm) in length. Adrenaline is one of several hormones produced by these glands. Along with norepinephrine and dopamine, it is a catecholamine, which is a group of hormones released in response to stress. These three hormones react with various body tissues, preparing the body to react physically to the stress causing situation.

The Fight or Flight Response

The term "fight or flight" is often used to characterize the body's reaction to very stressful situations. It is an evolutionary adaptation that allows the body to react to danger quickly. Dilated air passages, for example, allow the body to get more oxygen into the lungs quickly, increasing physical performance for short bursts of time. The blood vessels contract in most of the body, which redirects the blood toward the heart, lungs, and major muscle groups to help fuel the reaction.

When a person encounters a potentially dangerous situation, the hypothalamus in the brain signals the adrenal glands to release adrenaline and other hormones directly into the bloodstream. The body's systems react to these hormones within seconds, giving the person a nearly instant physical boost. Strength and speed both increase, while the body's ability to feel pain decreases. This hormonal surge is often referred to as an "adrenaline rush."

Side Effects

In addition to a noticeable increase in strength and performance, this hormone typically causes heightened awareness and increased respiration. The person may also feel lightheaded, dizzy, and experience changes in vision. These effects can last up to an hour, depending on the situation.

When there is stress but no actual danger, a person can be left feeling restless and irritable. This is partly because adrenaline causes the body to release glucose, raising blood sugar, and giving the body energy that has no outlet. Many people find it beneficial to "work off" the adrenaline rush after a particularly stressful situation. In the past, people handled this naturally through fighting or other physical exertion, but in the modern world, high-stress situations often arise that involve little physical activity. Exercise can use up this extra energy.

Though adrenaline can play a key role in the body's survival, it can also cause detrimental effects over time. Prolonged and heightened levels of the hormone can put enormous pressure on the heart muscle and can, in some cases, cause heart failure. Additionally, it may cause the hippocampus to shrink. High levels of adrenaline in the blood can lead to insomnia and jittery nerves, and are often an indicator of chronic stress.

Medical Uses

First synthesized in 1904, adrenaline is a common treatment for anaphylaxis, also known as anaphylactic shock. It can be quickly administered to people showing signs of severe allergic reactions, and some people with known severe allergies carry epinephrine auto-injectors in case of an emergency. For these individuals, dosage should be assigned by a licensed medical professional in advance, and instructions should be given on how and where it should be administered.

Adrenaline is also one of the main drugs used to treat low cardiac output — the amount of blood the heart pumps — and cardiac arrest. It can stimulate the muscle and increases the person's heart rate. In addition, by concentrating blood in the vital organs, including the heart, lungs, and brain, it helps increase the chances that the person will recover more fully.

Almost three years ago, I was driving to deliver some papers to the accounting workers. When I was texting on my phone, i noticed that I had accidentally entered the freeway at least 500 feet.

With little fuel and time I didn't have any other choice and I put the car in reverse. Trucks passed me and honked, and I start to get a lot of adrenaline, screaming with energy, and it gave me energy to destroy everything on my way.

Finally, after I got away with that dangerous situation and went into the accounting office with that energy level, there were three women that looked at me with a fearful expression, looked at each other and played with their hair (sexually attracted to me).

How do the adrenalin cells actually get to the place in the body where they are needed? Where do they travel? What do they do to affect you?

By anon927192 — On Jan 22, 2014

What does adrenaline do when you are playing video games?

Answer: It increases heart rate and gives people a tendency to feel pain harder than it actually is.

By anon353706 — On Nov 02, 2013

Adrenaline enters into the bloodstream, and is in turn given to muscles, along with the oxygen rich blood from the left ventricle. What measurement(s) is/are adrenaline measured by, if any?

By anon308143 — On Dec 09, 2012

I have been doing some studies into this since April of this year, and found some good answers online. If you are experiencing uncalled for rushes or 'panic attacks', the human liver is probably your main problem, as it is not functioning to its full capacity. This is dangerous. Adrenaline can poison you! You might be experiencing bad breath or/and hot feet, which are both signs of bad liver function.

When asking questions about your health it is important to ask yourself why you think things are happening, then find the answers to those questions. Personally, I've sought professional help since I was 24. I'm now 37 and none of the doctors I sought help from helped me.

I didn't know there are different types of doctors. However I do now, and one conventional doctor actually told me that vitamins are expensive and pointless. Did you know conventional doctors are trained in medical school to say that (to make it brief on why, it's because of money and where and how they make the most). This is not true! The main function of vitamins is to enable many chemical reactions to occur in the body, and these reactions help release the energy trapped in carbohydrates, lipids (fats and oils) and proteins. For example, if you drink beer, you urinate vitamin B stores in the body. This can make you go gray earlier in life. DNA obviously is different for us all, so different foods affect us differently.

I get cold sores around my mouth, but I do not get them hanging around anymore. Nope. Why? Because I no longer put the creams that are expensive on them. Instead, I reach for vitamin B and this works. My body is giving me a sign that my stores of nutrients aren't balanced. In this case, I know what works for me, but due to DNA differences, this may not be the same thing that works for you.

To get your liver working, you need to detoxify it, hoping you haven’t damaged it beyond repair. Added factors could be your environment, what you breathe or touch and your DNA. I detoxify my liver the Gerson way with coffee enemas. Remember, drinking caffeinated coffee does bad damage and causes you stress. If you need energy, why don’t you try to unlock it with vegetable juices that you make yourself?

I also try to avoid secondhand smoke. Note to smokers: Did you know that as you are thinking that the smoke is releasing your stress, it is actually behind the reason you are stressed? Sure, the chemicals in one cigarette will help to release serotonin and dopamine (you can research this yourself) but it's depleting your system of vitamin B. The breathing involved that is also part of the reason you become less stressed at the time of smoking. The lack of vitamin B in the body will help to make you wrinkled by the time you’re 40, and send you completely grey beyond your time.

I hope someone finds this helpful, and I hope you research yourself your problems, take a good look at the types of foods you are eating ask yourself where they came from, what methods were involved in farming the food, and what preservatives were used in packaged foods. We need to eat as close to the original food source as we can, and we need to make sure that food source was grown as organically as possible in an environment that is also healthy. Oh and an added note, the whiter the bread, the quicker you're dead.

My panic attacks are nearly gone. I guess I don't have to be on edge all the time. Yes, it's true people can turn it on whenever they want, but cannot turn it off whenever you want -- only sometimes.

I'm 37 and no matter how many doctors I went to, they never answered my questions when it came to me having panic attacks since the age of 24. Bad breath and hot feet are symptoms I have had most of my life.

To fix the problem, it is very important to cleanse the liver as it is possible to get the liver working back to full capacity. My point is how many people out there are taking anti-anxiety drugs (which never, ever worked for me) that are really just adding to the poor health of the liver, and not fixing the problem at hand? Xanax ring any bells? Valium, well that did nothing for me. It was Xanax that worked, however it only worked during the period I was drugged.

When I get an adrenaline rush, I feel a lot of excitement and my heartbeat becomes faster and faster and I can feel it all over my head like it was going to explode.

By anon300118 — On Oct 28, 2012

I always get constant adrenaline rushes. I'm always hyper and sometimes I get chills down my spine, I shiver and laugh like crazy. My friends have witnessed this and it is becoming increasingly part of my daily routine without my conscience.

I'm only 15 and now this is starting to worry me. I'm too scared to go to the doctors and my teachers have also picked up on it. Any help as to how to reduce these rushes?

By anon294976 — On Oct 03, 2012

I know what it's like living without the ability to produce adrenalin. I've been without adrenalin since birth.

I know it sounds bad, but to me it seems very good to have no adrenalin. My uncle's heart blew up in a bloody mess a couple of years back, since he had around 5000mg of adrenalin.

In fact, my aunt died yesterday in a car crash. But that's on a completely different matter. I think the human race should devolve so it doesn't have the ability to produce adrenalin, so our hearts don't blow up.

I've suffered from Inclusion Body Myositis now for 14 years and there is no cure for it as yet. I contracted shingles and I was given medication the same day it broke out. I did not have the discomfort that is connected with the shingles. But three days into the medication, I had a great experience. I was feeling great. My IBM was not there. I could walk and get up from seats without help from my arms. I thought I had found a cure for IBM. It lasted a day, then back to the IBM.

It happened again two weeks ago and it lasted for two days, why? Now I was not taking any medication that were different from my usual.

The professor who is looking after me has said in 20 years he has never had any of his patients that have IBM have ever stated or that they have had this experience, so why me? My doctor said it could have been an adrenaline rush?

By anon264431 — On Apr 27, 2012

If you're having an adrenaline rush all the time, you need to go to the doctor because too much adrenaline can kill you.

By anon255551 — On Mar 18, 2012

An adrenalin rush happened to me last week, and it never stopped. I know it sounds weird to some people, but I am sure there are people out there who have the same kind of feelings -- feelings of motivation, focus, confidence. It improved my hearing, and when I go to the gym, I can push more.

It normally lasts four or five hours and to refill I need to have a 30-minute nap. I woke up with an adrenalin peak again. It doesn't affect my sleep but it does give me a little headache. I am a little worried, though. If anyone feels the same way as I do, please comment.

By anon253064 — On Mar 07, 2012

I had an adrenaline rush that has not ended. I have had to sedate myself for the first several weeks to sleep and had to meditate for several months to cope with my issues that caused this, but I believe our ancestors operated with heightened adrenaline.

My blood pressure was at near lethal levels, but through meditation, I think it's subsiding to a safer level, but the benefits of motivation and lack of appetite, and focus seem to be worth it. It's not easily done and one must really understand human chemistry to live this way.

I take vitamins and use sedation still, but I am excited all the time and know that many illnesses stem from modern destimulation associated with non-instinctual lifestyles.

I cannot recommend that you do this yourself, I may die early. I will tell you that to make the transition, you will need to do breathing exercises to increase your red blood count to acclimate to your new system (at least two weeks). It is also hard to live a normal lifestyle. You may have visions when you rest, but sleep will be deep and profound. I know I'm lowering my blood pressure because I don't feel like there's a constant earthquake happening.

Good luck to you on your quest if you, like me, have issues that require you to operate on a higher level.

By anon246230 — On Feb 08, 2012

To experience adrenalin you must go through a lot of different experiences and extreme crap in life, usually on the edge or near death for it to peak.

My adrenalin is good for running and pain as I can run twice as fast and I cannot feel anything like when I punched through glass. When I broke my arm, I didn't feel it until 20 minutes later.

For me, it's not so good in a fight. I get too angry and cannot think straight and go to being a psycho witch. It can lead me to lose control in a fight, but I cannot feel pain as a plus.

By anon243468 — On Jan 27, 2012

Okay here's the deal and I'm using this as an example but it really happened.

Well anyway, about three years ago when I was nine, this dude in my grade wouldn't stop hitting me and I got super mad and went to take care of the problem but before I could get to him, two other kids in my grade, both about twice my size and weight, grabbed my arms to stop me, so here I am, only about 4 feet tall and about 58 pounds and not in the least bit muscular and I'm going up against dudes that look like giants compared to me.

Now everyone at my school who knows me knows I have a bad temper, but like I said, I'm small and a little weak and I'm literally dragging the two dudes trying to hold me back. I know it's adrenaline but I'm wondering if it's normal to have that much of a strength increase from something not life threatening.

By anon235504 — On Dec 17, 2011

My adrenalin is weird. Whenever it activates, I lose control but can still see and feel what's going on, but with my adrenalin time seems to slow down almost to the point of frozen time, and it feels epic, but when it stops I feel exhausted.

By anon234807 — On Dec 14, 2011

I've had some adrenaline rushes in my day. Considering I'm a kid, obviously I'm going to do stupid stuff and I'm going to get in trouble and my friends are crazy and do some of the craziest stuff. I hang out with them for the adrenaline and I like it. It doesn't last forever, but it feels good.

By anon231388 — On Nov 24, 2011

adrenaline is like a temporary steroid. i often measure the length of my vertical leap. after the adrenaline rush, i can jump about 20cm higher.

By anon220237 — On Oct 06, 2011

My dad is 45 and is a very strong muscular man. He's a mechanic. I'm 15 with an athletic build with not much muscle, and only just hitting puberty.

One day, my dad takes me to the work shop for work experience, and he starts working on a car, asking me to hand him tools etc. Then all of a sudden, a massive chunk falls out of the car onto my dad. He can't lift it, and I, the non-muscular athlete build, drag him out of the bottom of the car and throws the crap half way across the room.

Please explain. I have never been able to do this and now my Dad gives me weird looks!

By anon211281 — On Sep 02, 2011

Can adrenalin be like your high? Like one day I was just acting insane and couldn't stop moving and my pupils were getting big and small.

By anon201775 — On Aug 01, 2011

I had the best adrenaline experience where I was relaxed in the bush and a wolf from out of nowhere came out. I crapped a brick and I was in flight mode as a natural instinct to just run because I'd die fighting. I jumped up a large rock when being chased. Because of the huge adrenaline rush, I would have never have been able to jump as high or even get up that rock without it no matter what.

Once i was up and the wolf could not get me, I was buzzing like I was on the hardest drugs. I could not think clearly and was pumped. Later on when I relaxed. I was starving and noticed a huge gash in my leg that killed with pain when the adrenaline left.

Thanks adrenaline, you saved my life even though I lost about a week off it from the stress squeezed into one compact ball of extreme pleasure.

By anon196837 — On Jul 15, 2011

I'm 16 and every time I get mad, my body starts to shake and I can feel the blood rushing through my veins. I'm not really sure how to stop it.

By anon195080 — On Jul 10, 2011

Excuse me. I saw a comment saying that she could turn on and off adrenaline. I would just like to inform you and any others who experience this that you are not alone. I have been able to do this ever since I was born.

I can sleep fine, but every time, I get crazy extremely vivid dreams.

No one knows I can do this -- not even my parents.

I'm no expert, but I do have experience. So I would say it's only common sense to use it when needed, example: occasionally in sports, competitions, or in real emergencies. Or of course if you just want to show off.

Just don't so anything stupid with this ability. It can be harmful to your heart. And most important, have fun with it! Some people would die to have this ability.

I hope this is correct, because if not, I would look really dumb right now. As far as I know, it is correct. Stay safe and have fun!

By anon183928 — On Jun 06, 2011

Look: adrenaline rushes actually can last a very long time -- up to an hour. Personally, I am not sure if I have ever had a real one but I know someone who has and he said it actually can last a while.

I believe though, that my body has started giving me adrenaline to replace the energy I have failed to obtain. I rarely eat during the day and at some points I am shaking from no food (which is bad), but when I start doing an activity or playing a sport it's like I have been eating all day.

I don't know why, but this now happens almost every day and I believe my body is now using adrenaline as a substitute for the lack of energy.

By anon180966 — On May 28, 2011

What if you never get adrenaline rushes? I have stopped having them the past five years. I know this because i always used to get them like if i was driving and didn't look in my mirrors then i suddenly looked in the rear view mirror and there was a cop car right behind me i would get a massive rush. This hasn't been happening anymore, and was wondering if anyone knew why this is?

Also, i would always get a rush with my orgasms and now i don't and that is pretty much the whole reason for the orgasm, to feel that rush in my chest. So now i just don't even care about sex anymore since the feeling is gone now.

By anon180661 — On May 26, 2011

well i just turned 16, and i have been able to make my body feel as if i were on the drop of a roller coaster for a while.

I researched a bit on what it might be and I'm pretty sure it's a small adrenaline rush. each time i do this my pupils dilate to the point where i look like i just got some eye drops from the doctor and i can barely see anything but black. I also checked my pulse and it increases my heart rate by a lot. Tested it at school and it increases my one rep max during workouts by about 10-15 pounds for bench, and about 30 for squats/leg workouts. Just wanted to share because i know for a fact it is possible to control an adrenaline rush.

By anon178689 — On May 22, 2011

Basically, adrenaline is something that pushes your body beyond its limit, which is why you feel rather tired after. Also, it is not your body that knows if you are in danger, it is actually you. You are passively making the adrenaline.

By anon176302 — On May 15, 2011

Adrenaline does not open or dilate the blood vessels(as stated above); it constricts them, which helps with swelling and allows the circulatory system to focus on supplying blood to the major organs. Anaphylaxis will cause the blood vessels to relax, which makes them leaky, causing swelling and a decrease in blood pressure.

By anon175027 — On May 11, 2011

I read a comment that says that it is impossible to control this hormone. it is possible, all you do is to get really excited or stressed. This is how I get the rush.

By anon175026 — On May 11, 2011

I am able to release small amounts of this hormone into my body at will. When I want to, I relax my body and stop breathing, then I then suddenly get a surge and am able to do things like heavy lifting.

By anon175023 — On May 11, 2011

I feel stressed all the time and am thinking, after I read this article, that adrenaline is caused by high stress. Is this true?

By anon173926 — On May 09, 2011

I don't care what anybody says: i can control my adrenaline at will. It may not be a full 100 percent adrenaline boost but i can definitely cause a smaller surge at will. All i do is breathe in deep, tense my muscles then release like I'm stretching. i then feel the rush through my body and my heart beats faster.

I generally find when i am excited my breathing starts getting harder and i get constant adrenaline boosts.

By anon172040 — On May 02, 2011

Quick question to those who know a lot about adrenaline and exercise. I've been having strange reactions. After doing extreme muscle endurance (not cardio) activities at the gym, about 15 minutes later when i am usually home, I feel like im having a panic attack. my symptoms are usually rapid breathing and i have the urge to flex my muscles. It happens for about two or three minutes.

I'm 170 pounds, very athletic. I'm a former Marine and have been going to the gym for over three years. Working out is nothing new to me.

This started recently -- about a month ago, after i got out of the Marines. I took a three or fourth month break from working out completely before going back to the gym.

I've never had this happen before ever. I tried looking up what this "episode" is but all signs show a heart attack, which i highly doubt, and looking at the effects of adrenaline, i feel like my body is delaying its release of adrenaline until I'm done exercising.

Any suggestions? Thank you.

What is adrenaline's role within the body?

By anon164562 — On Apr 01, 2011

Just had a rather interesting encounter. It was an important day and I was ready for war even before stepping on that plane. The plane suffered an engine failure shortly after takeoff and I had a definite flight or fight response. I was searching for negative aftereffects of the flight or fight response. I felt utterly destroyed, like I had exercised for hours just physically tired and this empty feeling. All the positive stress and "edge" I had acquired for that day just evaporated as the high left me. I guess it's just physiological?

I'm fairly sure it was a "comedown". Heck, people were asking why I didn't take the next plane but I felt I couldn't perform at any level after it, figured I'd fight my battles another day.

I was on Prednisone and had a hard time tapering off. I was having anxiety attacks and still am, although I am not on it anymore. They are giving me Propranolol 3 x a day. How is this helping?

By anon161227 — On Mar 18, 2011

Some very interesting information on adrenaline here. I suffer from panic attacks to cold and also have asthma and asthma like symptoms often and panic attacks. Obviously these involve adrenaline. Can adrenaline cause chest pain as well? I have a lingering thought that once adrenaline is released, and the experience for one reason or another will not adequately flee (if there is nothing to fight but a mental fear or a past negative memory associated with the environment that the event is occurring in) then the panic/panic attack sets in.

I am trying to get to the bottom of my panic attacks.

By anon158629 — On Mar 08, 2011

I have a quick question: is it also adrenaline that makes me feel like everything around me is going really slow in a very stressful time, such as writing an important and very hard test?

Ex. Last week i was writing a midterm that was worth 45 percent of my mark. I went into the exam thinking i knew what to do but when i saw the test i realized i studied for much different things.

About halfway through i started to get really nervous and then all of a sudden my heart rate went really slow and i thought time was almost stopped. but the time went fairly fast. I was able to concentrate very well on the test and didn't feel very scared - almost like no feeling at all.

Anyway, what I'm trying to say is: does this have anything to do with Adrenaline. Or better yet does anybody else have similar feelings during stressful times? Thanks.

@166: Try listening to In The Hall of The Mountain King by Peer Gynt (through in ear headphones and with your eyes closed) I've listened to it on and off since I was about 3. Never fails to get me buzzing.

By anon152406 — On Feb 14, 2011

Adrenaline increases strength, speed and resistance to pain. It decrease fine motor control. It also changes your perception of time, which is why time seems to move more slowly. This may also be connected to the fact that your mind focuses more exclusively on the cause of the adrenal reaction - say the opponent, or the loud noise, or whatever.

You can encourage your body to produce adrenaline at will by imagining situations that would normally produce it, such as situations that make you excited or afraid or angry, BUT your mind quickly normalises to these stimuli which is why #166 no longer gets a rush from epic music. You can restore your responses by reducing your exposure to the stimuli (say by not listening to the music so loud - or not imagining the same situations) but it takes a long while - often months or more.

And to #165: No, I don't think that's adrenaline. I think that's just a heightened creative state, possibly temporarily brought about by diet, drugs or better communication between the two hemispheres of your brain. There are many possible causes. I find a creative rush is very calming, though mentally stimulating, whereas an adrenaline rush is like a compulsion to take physical action (dance, or fight, or run for example), coupled with raised heart rate and faster breathing.

By anon151865 — On Feb 11, 2011

@#166: If you're expecting it to happen or are trying to trigger it intentionally you may have become overly aware of it (like building a resistance) or your mind somehow keeps defaulting to a state that perhaps you're preemptively jumping to and thus preemptively preventing it from occurring. Or something like that because I'm having difficulty explaining it.

Perhaps you should completely stop looking for the rush and just never think about it so your mind can either lose resistance or revert to a more pure emotional state that you may have inadvertently convoluted through the years.

once i got a huge adrenaline rush. i hit my head against a coffee table. i felt no pain and had lots of extra energy. 10 minutes later it stung like hell. i had to get staples.

once a rope swing broke and when i was 9 ft. up i fell. it took about two seconds but felt like 10. i instantly got up and though i had slid 9 ft. and had a 2 inch hole in my arm i got up and felt no pain. i walked home and went to the hospital.

it took the doctor 15 minutes to take all of the rocks out and i had to ware a huge annoying bandage for two weeks. i have also been able to control my adrenalin rushes but can only get minor rushes.

About physical reaction to adrenaline: My home was invaded by 3 armed men and we fought but they got the best of me and hog tied me in my house and I broke the zip ties they used to shackle my hands and feet( this was not a surprise) the surprising part was while waiting for police and trying to recap everything that happened I started vomiting.

Is this common? Was it caused by adrenaline or my nerves? By the way, I did not sleep for two days after this because my sense of security was shattered.

i have had many adrenaline rushes as a teenager in many fights and the first thing i notice is that i have tunnel vision and i get both faster and stronger. i believe i have the fight gland rather than the flight because most situations would have my fight back rather than run away.

adrenaline rushes can affect you can only after a fight will you feel the full effect of damage caused. this is mostly from being hit or actually hitting someone else. i broke my knuckle on the first hit in a fight but still managed to throw another eight without even flinching. this is because the adrenaline in my body allowed my mind to block out the pain because i needed to fight for survival.

Adrenaline is probably the most amazing hormone ever. Your body literally knows when you are in any sort of dangerous, scary, or life threatening situations as well as situations that would require you to do something out of your normal strength, speed, breathing, jumping, capabilities.

I know adrenaline very well. Here are some of the most interesting things about it and some of the wonders it does to your body (literally instantly.

Let's say you're sick with the flu, 102 fever, achy bones, completely clogged nose, etc. Then something happens that causes an adrenaline rush. Let's say you have a small-medium dog who you hear squealing and look out the window to see three coyotes mauling your dog (if you didn't know, coyotes are medium sized but rather spindly dog like animals and a human could definitely take them on). Basically, your body would immediately shoot adrenaline throughout your body at the first moment you notice the danger to your dog. Within literally one second, you would feel no fever, your bones would no longer ache, and your nose would become instantly unclogged. You would also feel the power to easily take on the animals with your fists.

Here is another situation. You are in a car and turn only to see your about to be t-boned. Adrenaline would rush through your body, and although impact would be in about 1.5 seconds, it seems like it would take 10 or more seconds. Here is why. Adrenaline causes your body, brain, and eyes to evaluate and make decisions many many times faster than normal.

Because of this, in that 1.5 seconds, you are able to see more clearly and more frames per second, and your brain will make 500 decisions in that time and your body will react. This is why people say it felt like time slowed down. This is because time basically did slow down. You were able to do things that would have taken multiple seconds in just a little over one second.

Also, i don't know about you but I've had run ins with bad police officers and i lost trust with them. And every time i get pulled over, adrenaline courses so heavily through my body. This even happens when i thought i saw flashing lights in my mirror.

Even though it's a false alarm, my body already released the adrenaline. This is the best situation because I'll be driving, have the rush without the terrifying situation, and you can take in the adrenaline high for all it's worth.

Key notes about adrenaline. It will allow you to do what your body normally wouldn't be able to do in a normal situation.

Here is the power of the hormone: if you sprinted for as long and as fast as you can your heart rate may be somewhere close to 180 bpm or 200 bpm, it would take minutes to reach this pace. Adrenaline instantly causes your heart to pump at 180 bpm depending on the situation. Instantly, no exercise needed.

Basically, adrenaline will do the following depending on the situation. It seems to know what you need to do.

Nose is clogged, yet you need to run for something: will instantly clear nose, and give you more speed than you knew you had as well as more endurance.

Broke bones but need to find help: it will literally mask the pain no matter how severe as long as it isn't killing you. You will be able to tolerate or not feel it at all.

Need to lift something to save someone: It will literally give you more strength than you are capable of. Don't know how, but it does.

Anyway, adrenaline is a miracle hormone, and obviously was evolved over time to be our last line of survival. Honestly, without this hormone, many lives would be lost.

All the stories you here of people rescuing, helping, surviving, all had adrenaline pumping at one point to help them. Honestly, even in non life threatening situations it helps humans. Police, firefighters, athletes all need it to make rapid decisions, and law enforcement needs it to save lives on a regular basis.

I love adrenaline.

I was involved in a few dangerous situations in which i naturally used adrenaline to keep myself alive. Ever since I've tried to replicate it and I've done it successfully with concentration. I've also learned to dilate my pupils on command. You need to rethink possible.

Maybe there's some crazy, abnormal person somewhere, who can control their heartbeat, their adrenaline, their energy, their muscles.

By kotendo — On Sep 04, 2010

Lots of people here think they can control the rushes. most of you never had a real adrenaline rush.

It's not a shot of chemical adrenalin, because that the only way you will ever control it is with shots.

they didn't invent those shots because it was cool.

If you're an optimistic person you will very rarely get rushes. If you;re a pessimist, you probably won't ever get one because optimists think everything will be fine and pessimists think they don't care.

You will only get a real rush in a real crisis. Like if bombs drop near your home, a private jet crashes on your house, you're driving at 140 km h and hit head om. those will give you an adrenaline rush, and a real one.

most of you are talking about guts, willpower or fear. those emotions can help you achieve things you would not without. but they aren't an adrenaline rush.

real adrenaline is painful after the effects. Real adrenaline increases all your abilities. Most people faint after a real rush. you can die from it. It is a last resort tool, after all. You can feel small burst time to time. but the effect should be almost non-existent.

It's like running a race or getting into a fight. These might give you small rushes. but the effects will be next to nothing. if i had to put it in numbers, real rush 100/100; rush very scared 30/100; everyday like rush 5/100. This includes fights, fear of something, falling from a rather high but not mortal height.

and others. Most people will never get a real rush in the whole life even in the worst scenario (gun at your head, for example). Every one will feel adrenaline in their life at least once, though it may be small.

Mo one can control it. Even though you can expect one to come you will never call it. try to tell your heart to stop. it's the same thing. it will never happen. don't force your heart to stop. some kids can be stupid and try to hold their breath thinking they will get a rush. you won't. you will die.

To get adrenaline it depends on your state of mind and the events happening. If its sudden or a long crisis. if you are on drugs, or alcohol. if you're stressed. lots of things come into play. getting an adrenaline rush is the last resort humans have as a survival instinct. you can die from it and your brain is made to protect your body. therefore before getting adrenaline, your brain will start its survival mode. if it fails it will start adrenaline.

so most likely you won't get a rush unless its a sudden crisis that you have no control what so ever about it and that you have no time to do anything. it is a last resort.

don't confuse courage or willpower with adrenaline rushes. they may feel alike but they are totally not.

Again, to make it clear: your basic survival instinct is to do anything to live, and adrenaline can kill you. you won't have it unless there is no other option. Don't expect to do the matrix bullet dodge, kids. they are in no way super human abilities.

The brain locks part of your strength to not cause injuries. if needed it can be unlocked with emotions: fear, joy, courage, willpower. You will feel stronger at those times and may produce adrenaline but at a very small rate, not even worth mentioning it.

also some people can get stronger rushes then others. if you could control it then it wouldn't be a dangerous thing. dangerous = locked by brain.

i hope this was useful. they are facts. those who say that can control adrenalin must take shots because it's impossible. it's like saying i control my blood flow. No, just no.

@beverly paris: he is having a panic attack or anxiety. adrenaline will never get high enough to be dangerous. keep telling him he is OK, healthy, and that he shouldn't be afraid, because *fear* is what happens to most people.

they have an attack, a very strong one (even though its not dangerous) and the person who feels it thinks he/she will die, afterward not knowing why it happened and how, they get stressed about which illness they have (none) and then due to stress they get another attack but weaker, and then start to be scared that it happen again, stressing them more. i like to call it the circle of death. not dangerous. no worries. lol. no one ever died of that.

it is a mental battle inside oneself. depending on the person it can last one or two weeks or a whole life. only consult doctors if the attacks happen too often, like more than twice a day in in the week or every day. otherwise you are just spending money for nothing.

he has to believe he is healthy and pass all tests. once that is cleared he knows he is healthy, but still fears. that 's where you come in. keep telling him he is OK and not to be scared of anything.

do sports, eat properly, sleep properly. Pills are really not the solutions. Trust me. I know from personal experience. Pills only increase the fear and they are most likely very addicting.

This is very bad for someone in his case.

you should take the initiative of controlling the amount of sleeping pills he takes. only when really needed. everyone can stay up 24 hours. if he can't sleep after over 40 hours give him one.

but i really don't recommend pills. I'm no doctor but anxiety is my best friend. After my first attack i went five days with no sleep, so yeah, i got pills too and a bunch of them. But i couldn't sleep without them anymore and every time i didn't take one i had an attack. it was never ending.

So i asked my dad to hide the pills. I didn't sleep for two days but then i finally fell asleep.

After that i was OK. I had some problems sleeping but no attacks anymore. in fact, i still have problems sleeping. I sleep every 35 hours or so and just now i have done 48 hours, slept six hours and I'm at around 19 hours up at the moment. I'm OK, though. don't worry. I got used to it.

He can definitely get out of that circle. I've been like that for around two years, and every day i feel better and better with no pills. The hardest part is knowing you're healthy and believing it. The second hardest is quitting pills. Then it's the recovery.

By anon108713 — On Sep 04, 2010

adrenalin works with high stress. it can't be controlled completely. You can produce adrenaline in dangerous situations but it won't be as intense as the *dangerous* moment that happens quickly

best example would be: you're about to get into a fight your adrenaline with pump a little. but you still feel in control since you can run away or you think you can beat em or you just know you won't die.

But. if for example you're in the passenger seat of a car and get an accident at 100kmh, and you don't feel in control of anything and you think you will die. your adrenaline will pump like no tomorrow.

it is impossible to be on adrenaline 24/7 because your body and brain won't allow it. but you still can get small rushes often in same day if your a really stressed person but it shouldn't be strong at all.

As for the effects of adrenaline, there are many: strength, speed, reaction time, thinking, seeing things somewhat slower, sightly feel pain or not at all. there are others. I just said those that come to mind.

also the seeing things slower – don't think you will do the matrix bullet dodge. you will see slower isn't really true, because what's really happening is that your brain is being overpowered and it analyzes thing much faster. you will see slow-mo and move slow-mo. which is why some people say things like “i seen my life flash before my eyes.”

The brain analyzes stuff much faster and some people try to think happy thoughts, or what will happen to their family and such and the brain shows you everything in a big lump. This happen really quickly, in less than two seconds.

My personal experience was in a car accident. I was in a 120kmh front hit. Two seconds felt like two minutes. i left marks on door handles by grabbing it hard and had pain in my arm for three days.

adrenaline is wonderful thing, yet very dangerous.

I had a major rush a year ago when I was outside of a Walmart, and I heard a scream, I saw three guys trying to pull a girl into their truck. there was no one in the parking lot, and the next thing I know I'm at the door of walmart telling a guy that a girl was being kidnapped.

I saw three guys take off toward the girl, then I was in my car sobbing so hard I felt dizzy and sick. I remember someone telling that the girl was fine. My mom came out of the store and someone filled her in what was wrong with me, I don't remember anything else that happened that day, just waking up the next morning.

Is it dangerous to have constant adrenaline rushes throughout the day? I have this one thought/ worry and for the past week it's been triggering an adrenalin rush through out the day. Sometimes i will get uncontrollable muscle movements (Small things like when I'm sitting my leg moves up and down). I just want to know if it's bad for you.

I've only had like one or two adrenaline moments. One was about a year ago. I was 13 and just got my got my bike all clean and fixed up. so when my parents left the house for a joyride around my local lake, on the way there we saw about four or five teenagers there looking for trouble. i rode by and they called me names. i didn't say anything back. i just rode on.

Well, on my way back, they called me more vulgar names, so i called them a bunch of puppies. That wasn't so smart. They all started chasing me, five 17-year-olds. The next thing you know, my adrenaline kicked in, and i pedaled my bike so fast and hard in less than two seconds my chain literally snapped. So here i am, riding a bike in neutral with five teens chasing me. so i get off my bike, run with it was fast as i can all the way down my block. In less than 10 seconds, I quickly rolled my bike over, fixed my chain in less than 7 seconds, when i saw a car drive up right in front of me. Then, out of nowhere, those five teens get out and come at me. I just stood there staring at them and the adrenaline was *pumping* like no tomorrow. I felt no fear.

I remember one blond one came up to me, and he lectures me, telling my not to do that crap. I'm all like "OK" and he backed up a couple feet then i saw them take some bats out of the trunk. as soon as they did, i quickly hopped on my bike and pedaled off at lightning speed, so fast they couldn't catch me, going down an alley way.

They all hopped into their cars and chased me, and i cut though the side of a few houses and I'm back on the main road. The next thing you know, (again) they were right behind me, then guess what? My dang chain breaks again, because I was pedaling way too fast, so once again, I was running with my bike down a busy road, running like 20mph and they're right behind me.

Finally, I got to the alley way next to my house, with them still behind me, and i run up into my driveway with my bike and let go of it.

i was running so fast my bike launched into my dad's truck, leaving a massive dent in it. i jumped over to my gate on my fence, ran into it, shut it, and ran inside and called the police. Later they showed up and they never found the teens, but someday i will.

All i remember is they drove a black honda civic. I will find them someday and show them not to mess around with me, but that's all a true story, my adrenalin story, but i remember everything. i felt unstoppable. i couldn't feel fear, exhaustion or weakness. i felt super strong, so strong i thought i could run 50 miles nonstop. It was the greatest, yet the worst day i ever had.

I have been researching adrenaline lately and how it works, etc. It kicks in when you need it most like in threatening, and scary situations. Because i am trying to figure out why i can't get one.

I have been in many situations that would cause other people go into shock, or have large adrenaline spurts but it never happens to me, no matter how frightened I am. I am curious to why this is.

I had a massive adrenaline rush a few weeks ago when i got held at gunpoint. I knew the gun was fake. i could easily tell but then i got into fight mode, not caring if it was real or not and my fight mode ticked and let's just say he couldn't get up.

i have an alarm system in my house so every day i set it. today i was home with my sister and we were cleaning, and she went left to go out side and shake out the rugs. I was upstairs cleaning the floor when suddenly the alarm starts blaring.

all i remember is hearing my sister scream and my dog bella, started growling and barking. next thing i remember is being in my room looking for a phone to call 911 and i couldn't find one. i don't remember running into my room but i did. i almost broke the window so i could jump out and get help, but i ran to the other side of the house to get a phone. right as i had it in my hands the alarm shut off. this all happened within 6 or 7 seconds.

Apparently my sister had opened the door but forgot to turn off the alarm. this happened about 45 minutes ago. I was shaking quite badly up until about 20 minutes ago but i feel exhausted and dizzy, and every time i hear a loud noise i flip out again. is this the after effects of an adrenaline rush? did i have an adrenaline rush? lalamb12345

By anon90934 — On Jun 18, 2010

To some people wondering why everything *seems* to be going slower: Adrenaline makes your heart pump faster, therefore blood travels a lot faster through your body. Meaning your brain gets a lot more 'feeding' than what it normally does. It makes you 'think' faster, and you perceive it as a slowed down portion of time. It is just your focus radius getting larger.

I've had many adrenaline rushes. I could never control them on will, although haven't tried much.

When I was really young, like elementary school, I used to walk over outer window edges to pass from class to class. At those moments, I was so pumped and not afraid, cause I somehow knew I had this 'power' to make it even if I somehow fell.

In elementary again, I went to get the ball from a yard behind my school walls. There was a dog there, and as soon as I kicked the ball into the schoolyard, it started chasing me. As a kid, I wasn't fit, and neither am I now. But for those two to four seconds I got away from it, I ran so fast and jumped high enough to get over a wall at least 2.5 times my height.

In my last years in high school, whenever the bus was moving already and I had lost it, I ran so fast that I could actually run side-by-side with it, until I knocked on the door for him to stop. I could run at least 200 meters side-by-side with it, and it accelerating.

Last thing I remember with adrenaline, it was just the other day. We were with a friend in a forest, took our airsoft M4s and knives, and went searching. We found a farm, and there was no one there besides animals. At some point, my friend to my right, I hear a sound. I immediately turn left and see a dog coming right at me. Somehow I realized really fast that it was on a leash. One second later, another same colored dog does the same with a leash. Thinking we are safe, I turn to my friend to tell him it's OK, but I see him running as fast as he can far away. Thinking I should follow him so I don't get lost later, I start walking hastily to his direction. Then, on instinct, I turn to my right and see a dog literally one meter away from me, running towards me. With a bag full of stuff in it, a realistic-weight M4 on one hand and a knife on the other, I start running.

On uneven ground, against a dog, getting away would probably be impossible, since dogs are excellent runners (against humans at least). Seconds after I start running, I turn back to see how in hell I still haven't got bitten. I realized that I had left a big distance between me and the dog in only 2-3 seconds, and kept distancing away from it. I couldn't feel any pain in my muscles, and I had no problems breathing, as I normally should. After about 300-350 meters I looked back and I had lost the dog.

My point is, adrenaline kicks in when your body feels extremely threatened to handle a situation with your normal reflexes and strength.

I don't know if you can really call it by will, but it's sure to kick in in a situation where you need it.

To some people it gives little advancement to their 'powers'. To me, it gives a huge boost. I literally feel untouchable.

The fact that we could be able to call it by will would make adrenaline useless, as when your body releases it, it's a moment you want to remember. Think of it like this: If you didn't know what freedom is, you wouldn't mind being a slave.

The same way, if you can release it by will, it means you won't be able to tell the difference anymore between *on* and *off* mode, meaning you won't be able to live the moment, and possibly deactivate the boosting effect it gives your body.

Don't abuse your 'powers'. -Anon S

I often have adrenaline rushes when I am deep in thought. It usually tells me to act upon it. My heart rate goes up, breathing becomes complicating, and I begin to feel light and dizzy at the same time. Is this normal? Thanks.

We own a restaurant, partly with my son. He asked me to fire someone today, which I did. He also asked me to cancel a band that was going to play tonight. They are lewd. We are not prudes, but this band goes too far. My adrenaline is still rushing through me. Haven't had this feeling for a long time. Part of me likes it but part of me does not.

I had a major adrenaline rush last week because of an incident on my job. My job is to listen to people give their comments and opinions all day long (loads of fun).

This man called up to give his opinion and started to spiral out of control because I wasn't "agreeing" with him, which I'm not supposed to do -either way. He got so mad when I was trying to redirect him that he called me this horrible name and my voice turned into something from a horror film when I aggressively told him that he better not ever call this office again and talk to anyone like he did me. He ended up disconnecting and saved me the trouble!

I was furious and everything started to go haywire. My heartbeat was pounding and I had people coming in to check on me. I would think about it and the process would start all over during the course of the day.

When I got home, I drank almost a whole bottle of champagne by myself (I rarely drink more than one glass of wine or champagne in one sitting these days) and took two Benadryl (usually knocks me out like a sedative). I stayed up until 12 or 1 and was up before nine the next morning, feeling like "business as usual".

Needless to say, my husband was amazed and I knew it could only be adrenaline!

I have been sick for the past two days and haven't eaten much. I was awake since 2 o'clock in the morning last night unable to sleep with my fever. At about 6:30 in the morning my stomach really was starting to hurt as i began to feel more and more hungry.

I walked downstairs and attempted to make cereal. I began to get lightheaded and the next thing i knew i was on the ground. As i was lying down, trying to find out what happened, my heart began beating extremely fast and i began sweating until i was in a pool of sweat.

I didn't feel the pain from my skinned elbow, cut foot (from the bowl shattering), and head (i believe it hit the ground.)

By anon74861 — On Apr 04, 2010

Well Brazilian jiu jitsu, you don't know what you are talking about, because they have medically confirmed all the things that most of these people are talking about.

I know when i was at a very young age my dad tried to kill me, but he failed as you can see! i was only 13 and my dad was in his early 50's. at the time i wasn't very physically inclined, but when i had my adrenaline rush from him coming into my room with a gun i strong armed him and threw him to the ground.

So there is a truth to the adrenaline and giving you super human strength.

By anon74653 — On Apr 03, 2010

Adrenaline rushes are also achieved when you have a panic attack. If you think you can't control adrenaline then how do you think we can control panic attacks? When our minds are freaking out and over-thinking stuff, we notice it as a threat.

I have adrenaline rushes all the time brought on by myself. Just think and i can get it clicking. It comes in useful when i must fight but the problem is it starts up very easy and so the smallest thing bit of excitement or someone starts talking to me and heart rate goes up stinks sometimes. otherwise it's great.

I had a great adrenaline experience in school a few weeks ago. Now I pride myself on being a pacifist and I don't like violence unless it's movie comic book or video game which has made me very susceptible to bullying from other people in school.

I was in the standing in the corridor waiting to speak to my teacher when two bullies, Alex and Adam started picking on me for the millionth time.

My Nana had recently died so I wasn't up for confrontation and I told them where to get off, whereupon my heart rate increased and I zoned in on the pair of them. everything else like vanished and I saw in slow motion alex's fist coming towards me.

I dodged all 10 of his punches and then (unlike me) punched him in the face, breaking his nose and pushing him over where Adam jumped on my back and I slammed him into the wall, dislocating his arm!

Is adrenaline capable of doing this because after it happened I collapsed with exhaustion and I didn't get the blame because I don't like violence! How awesome is that?

Another true story: I was 13 years old and my dad said he would take us to get some video games. I had gone snowboarding the day before and got amped up over what an awesome weekend I was having.

In a moment when I was excited, I jumped off the stairs between the second and third story floors and tried to catch the third story landing, slipped, backflipped 1 and 1/2 times landing on my neck, arm, and hip. Needless to say, I was carried away with two fractures and couldn't walk or sit up independently for two weeks.

After landing I couldn't get up, so I looked around for something to pull myself up with and proceeded to see my right arm curved extremely severe. I thanked God for adrenaline knowing I'd soon feel the worst pain I'd ever had. I then said: "*moan* Aw crap, I broke my arm." Good times.

anon68754: this is the after effect of the adrenaline rush because your body goes all out for a few moments then afterward you need to sit down because of the overload. it happens to me too, but i know when i get a rush and what to do afterward.

O.k. first off, i am a lineman that weighs 200 pounds but am mostly muscle, now most of the lineman on the other team seem to be about 225-250. During my last game of my middle school year, the last few plays, i was able to hold back four of them, all pushing on me. How is this possible even with the help of adrenaline?

By anon66651 — On Feb 21, 2010

All you people saying "you can't control adrenaline rushes" are actually kind of wrong. I can, i do it all the time.

I've actually had my heart rate timed, and I've sped it up every time and dilated my pupils. It's easy, like raising my arm.

i understand most people can't do it, but some can. it must just be some genetic mutation, i dunno, but I'm perfectly healthy and i give myself adrenaline rushes all the time. it's nothing amazing, it's kind of useless to be able to do it.

if you need it, you would get it anyway, and if you don't need it, it's kind of pointless having it. I'm just saying, it's not some far-fetched thing. Most people can't wiggle their ears, but some people can. there has been actual research proving that some people can induce adrenal responses. it includes pupil dilation, increased heart rate, change of electric potential of the skin, raising of hairs on skin and activity of the premotor cortex of the brain.

Can't slow stuff down though. i can just give myself the effects of an adrenaline rush and then return to normal. can't slow my heart or constrict my pupils.

By anon65362 — On Feb 12, 2010

i always have this rush whenever i feel like I'm competing with someone physically. If i fought with someone verbally and feel like it's going to be physical the next time i see them, then the moment i see them i feel this huge rush and my heart beats very fast. Or sometimes, in a simple soccer game or if i am about to race someone in running, it starts automatically. it's amazing.

I was going down my driveway on my new bike that didn't have tricycles so i wasn't used to it yet. My brothers were on the front lawn throwing the baseball to each other. This may sound stupid but I basically forgot how to stop. So here i am, three feet away from the nine foot drop at the end of my driveway.

At this point i was able to notice every detail. Before I knew it, I was in the air. Oh yeah- one of my shoelaces was stuck in the pedal. Since I was only seven at the time i did the thing most seven year old kids would do: I closed my eyes.

Amazingly i ended up holding on the side of the end of the driveway. Don't ask me how but somehow i managed to not fall and break something. Please leave comments.

Is adrenaline (also produced by the adrenal glands in response to stress) the same substance as cortisol? If not, can someone please discuss the difference?

By anon64206 — On Feb 05, 2010

For all the people who said you cannot control your adrenaline, you are wrong on multiple levels.

First of all, you can control it externally. For example, you can control how often you pee, correct? Obviously by watching how much fluid/diuretics you ingest. Same goes for repeating a behavior or physical motion which produces adrenaline.

If you consciously associate that situation, movement, or even intense thought with the sensations of an adrenaline rush, they will most definitely occur. I know this as a fact as it happens to me often.

I am a 65 year old woman and have type II diabetes. Several times per week I get the "tremors" so severely that I feel my legs are coming out from under me - I can't control a pen because of the shaking so badly.

I test my sugar levels and sometimes it's high - sometimes low. Today when I came in, it was 77. Could this be adrenaline or low sugar? I have to leave work sometimes because it's so bad.

I have chronic daily headaches. Although they've been called tension headaches, I don't seem to have them while experiencing lots of stress. Could it be that adrenaline is making my headache go away?

Adrenaline has saved my little sister's life twice now, but I have also seen how it effects her after the shot. She goes completely limp and turns extremely pale, and she often throws up. It lasts for several hours after the shot before she regains some strength. Don't mess around, people.

of course it doesn't cause erectile dysfunction. People have had adrenaline rushes and are still fine.

By anon50778 — On Oct 31, 2009

what 'dangerous and unexpected situations' trigger the release of adrenaline into the body as a natural defense mechanism? feeling hate/tension could be an alternative diagnosis.

By anon48194 — On Oct 10, 2009

I heard that adrenaline rushes can cause erectile dysfunction. is that true? If it is, does it wear off?

Adrenaline actually increases matabolism of carbohydrates so it would actually help lose weight instead of gain it.

By anon46321 — On Sep 24, 2009

I have read somewhere that the adrenaline system can cause weight gain. Is this true? I can not lose weight, tried diets, exercise and most any other suggestion people have given me. No luck at losing more than 2-3 pounds. Could someone help me with losing weight?

For the last few months I have had adrenaline issues. At first, my MD diagnosed it as blood pressure problems. Put me on blood pressure meds and that did not correct the problem. It all started when I was rushed to the hospital with a BP of 190/110. I am only 32 years old. So I started taking the blood pressure meds and thy adrenaline rushes were not stopping. I was getting severe discomfort in my chest, to the point I thought it was a heart attack. But I have been through the entire series of heart tests and everything came back normal.

I am at a new doctor today and they have diagnosed me with thyroid problems. I have been taking thyroid meds for about a month now and still am getting the adrenaline rushes every few days or so. Not as severely as I was before. My doctor then had me take an adrenaline test which requires you to spit into a tube 4 times during the day. You send it to a lab and they send the results to your doctor. My levels of adrenaline were 3-5 times what they should be. So they are trying now to regulate my adrenaline with meds. I am taking Travacor 3 times a day. It's been only a week, so I don't have any "results" yet.

To anyone who thinks adrenaline rushes can be controlled and are a good thing, I am telling you through experience it's simply not true. They are terrifying, and cannot be good for your body. I'm just hoping they can help me and stop the rushes.

By anon39807 — On Aug 04, 2009

i have read just a few of the recent posts up and i would like to put my two cents in. first off i do believe you are able to produce an adrenaline rush at will, even if it may not be a strong one, only because of the fact that when you have an adrenaline rush its because of some fight or flight situation (blah blah blah yeah yeah) which is either a feeling of fear or excitement, etc. so then the brain takes that feeling and transmits those little brain waves to the gland and says "yo release the fluids!" so yeah like everyone knows you only use 10 percent of the brain so let's just go on and say producing an adrenaline rush at will is very possible with the other 90 percent. all you non believers, just because you can't do something cool like that doesn't mean no one can. and i like the guy talking about dissertation on adrenaline, he seems like a smart fellow. i would like to see that site one day.

By anon38955 — On Jul 29, 2009

I can answer your question. your brain like some others has a link to your body functions controlling anger. I can do the same thing. it is addictive and you should be careful when you do it because you can pass out

By anon38066 — On Jul 23, 2009

Well, I'm not sure if it is adrenaline, but there is something i can do at will- without getting angry or listening to loud music- that dialates my pupils and increases my heart rate. It really takes little effort at all, easy as flexing a muscle. I hope it isn't adrenaline, really, considering all the health factors that seem to be connected to over using adrenaline. Anyone have an answer to my mystery?

By anon37664 — On Jul 21, 2009

I am doing my dissertation on adrenaline and the positive benefits of having a rush. I fly big kites and it gives me a brilliant rush, like feel the fear but do it anyway (cheesy I know!) I think that there is not enough adrenaline in our lives - as the cave person would have had to survive and hunt etc, we (in the west) no longer need to and our adrenaline is now considered to be negative because it is labeled as the stress induced by a constant adrenaline overload at work. I think that there are a lot of people who would have been really useful in the neolithic times that are out there stealing cars and joy riding or committing other non-acquisitive crime to get the same buzz they would have had by hunting and tracking. I think that adrenaline is not as negative as everyone here says as long as you run/exercise it off afterwards. this then produces seratonin or dopamine in the brain which is a relaxant and produces the same effect as the 'happy' drugs (like MDMA etc), and it is all natural!!

If anyone has any comments on this please leave a message below. Website details for my disertation research will be put up soon and any help is appreciated.

some of these posts are complete bull. adrenalin is only released when your body needs it or if you have a genetic dysfunction. you cannot control it or release it when you desire. what you are probly experiencing is all in your head, you just think you can.

By hines3 — On Jul 15, 2009

Adrenaline is a powerful thing to have. It's the pretty much the panic switch that sends you into a state of superhuman like abilities. True story: when I was 8 years old, I had gotten over-excited about my friend visiting. I was running all over my house (no adrenaline influenced my excitement). I had for some reason grabed the edge of my couch, and propelled myself high into the air by accident!! The way I was falling I would have landed on my tail bone and broken it!! Out of nowhere adrenaline kicks in and it was like my brain had no control of my body anymore! In mid-air I had spun 180 degrees, so now I would land on my stomach. I cushioned my fall with my elbow. The best part was this all happened in a matter of seconds!!! The slow motion effect comes from you moving abnormally fast. Not many people can say that they've spun 180 degrees in mid-air when you're less 3 feet from the floor. Unfortunately the crash (or cool down) your body goes through is extremely painful. Adrenaline truly is a powerful thing.

By anon36505 — On Jul 13, 2009

Is it possible to dodge a bullet with adrenalin? Or move another place in a certain amount of time, like seconds? And how to control the adrenalin?

By anon36233 — On Jul 10, 2009

6 hour adrenaline rushes, neck-breaking,death defying acts, complete control of the adrenal gland...science-fiction stories. As any doctor would inform you,you *can't* control you're adrenaline rush. The human anatomy doesn't permit you because although andrenaline generates a feel good mood when its effects wear off, it indeed overdrives all of your vital functions and you could wind up with torn muscle tissue(it enables extended use of the muscle fibers, more than 33% the normal value, hence the increased strength) and even a heart attack. Listening to loud and aggressive music, anger, be it natural or self induced, trigger the release of adrenaline in your body,but you can't call it a proper rush. The blur in the one-on-on fight, the greater strength, it's nothing compared to a true adrenaline rush. I've experienced normal adrenaline reactions many times and i'm sure many of you had. But,i've also experienced one true adrenaline rush: It happened in the third week i got my driver's license. i was driving fast and aggresively, trying to impress God knows who(total lack of maturity and proof of stupidness) and at some point in a turn I lost control of the car. i was going something like 150 kmph. luckily the road was clear and i managed to regain part of the control and to finally brake before hitting a pole, but believe me the fraction of a second i lost control seemed like a minute,no exagerations. i looked in the mirror and my pupils were enormous,my heart was almost bursting through my chest. When i tried to regain control of the car my hands locked so tight on the steering wheel that I managed to dent it,and i remember that my focus was so great that i managed to see every possible detail on that road. After stopping and pulling over it took me 10 min to recover. I was experiencing extreme chills over my whole body and i couldn't concentrate on anything else than how to escape the dangerous situation that in fact, had ended some time ago.

By anon36057 — On Jul 09, 2009

adrenaline doesn't hurt your heart or anything. it makes your heart stronger. That's just like saying exercise makes you weaker. It's a good thing to use your adrenaline gland. The more you use it the stronger the gland and you become. You'll just have to learn how to tell your brain to put a certain amount into your body. So you don't pass out if you put too much in or something.

By anon35973 — On Jul 09, 2009

It can be bad as you can't feel pain right? i played football a lot and use to get them! it was great. i made plays i normally couldn't do! which led me to always get 1st string, but now that i am a little older i had recently gotten into a fight with 3 guys because of adrenaline and the marine corps teaching me to fight. i was able to win and they ran but the next day i had to go to the doctor because i had torn every muscle in my body do to it...if you have ever pulled a muscle then imagine that all over your body..took me awhile to recover from it and it hurt so you do have to be careful. that's the only side effect that i can say i don't want again

By anon35335 — On Jul 04, 2009

I fought in elementary school too much. Kids used to pick on me, because I was kind of a loner and one of the smallest boys in our class.

Before the fight, I first feel hot, than my arms start shaking noticeably. In fight I don’t feel pain as something unpleasant, I’m stronger, quicker to react and I do things I can’t remember how exactly I did later. After fight I sweat a lot, I burst in short cry (possibly of anger), I need to go to bathroom and pain once again feels like pain. Also after the fight, I feel great – like on drugs or something,…

By getting myself intentionally angry or anxious – aggressive & loud music, shallow & quick breathing,… I can reach something like mild form of rush, and yes, it feels great.

I decided to stop intentionally getting rushes, and to try to avoid fights. If I swat, cry and go to bathroom after it; it can’t be good for me, I picture it like putting my body in overdrive.

Hope this short description of my experiences helps someone.

By anon35037 — On Jul 01, 2009

Hi. I play video games I read that they trigger release of adrenaline. I like playing and do not want to avoid them all together just wanted to know what would be a good amount to play games without releasing too much into my blood

By anon34035 — On Jun 16, 2009

i'm surprised at the amount of people actually get adrenaline rushes and i'm even more surprised at how many people can control them, how much (in percentage) does adrenaline improve you're physical strength, also i've had one once in a fight (well kick boxing fight) and someone punched me and i was bleeding but i didn't feel a thing. is this normal?

By anon33886 — On Jun 13, 2009

My Adrenaline Glands Are about 4 1/2 inches as compared to the usual three. My doctor told me it's very bad for my health when I get adrenaline rushes. I used to pass out every time I got a rush. Now that doesn't happen anymore. It feels *reeeaally* good getting the rush.. but when i come off of them it hurts sooooo bad... My doctor told me he didn't really know why and told me to do my best not to get excited... does anyone on here know how to help?

By anon33645 — On Jun 09, 2009

I am surprised to see more people claiming they can control their adrenaline glands. I have been able to do so since I was 10 or something. I'm much older now and still can, I experimented a lot with that, but never got to a point of fainting or coughing blood ( ? ). I have read elsewhere that someone linked it to intense headaches but I don't think I've got any.

I found tho that you can pump more adrenaline by keeping your tongue touching the top of the inside of your mouth, I tested it and it worked out. After a while I could, like a couple other people who posted, only focus the pressure in a body part, so I was wondering how that was possible, I thought adrenaline was affecting all of your body.

Sometimes it feels like it's more like electricity, it feels staticky. If someone has some decent info, I'd like to hear it.

I am 14 years old, I have many questions about adrenaline. I play as a runningback with older kids in high school and most days I purposely think of something to make me mad and I run faster and hit harder to keep up or even better. My past was real rough for me and when i'm not playing football or at the gym I am positive and happy at most times, but everyone has their days. When I get hurt on the field at anytime I don't realize I am until I am calmed down. Is this bad, or is there someone that can relate to this that knows whether its healthy or not?

By anon33153 — On Jun 02, 2009

I get adrenaline rushes all the time. I can't do it at will, but it gets triggered really easily. I have fainted twice because of it. I had a skin biopsy and everything went well except for when I stood up my blood vessels dilated so fast that my heart, which is very strong but i have a very slow resting heart rate 40-50 beats a min (which is very good), did not stay up and I passed out and it happened a second time. So I went to the hospital they did a ekg or a eeg I don't remember and that's how I found out my blood vessels dilate quickly and stuff but it's good in other ways cause I can pump a lot more blood in less beats.

But in speaking of adrenaline rushes, my freshman year this kid tried picking a fight with me and punched me after that I can't remember much but I asked people and they said they pulled the kid away from me and pushed into the hallway to break it up and what I do remember everyone was scared of me. And I when I did wrestling my matches that I got anxious before I could not remember even if I won. It happened so slow but so fast. And same when I pole vault things go slow but it feels fast cause I can't remember anything.

By Jordan1235 — On May 16, 2009

for some reason i was trying to see if i could try to start an adrenaline rush by myself. i just simply clenched my fists flexed really tightly all around my body and focused on flexing and this power felt unbearable. i was wondering if i activated some type of adrenaline rush inside of my body? it felt very good. it made me feel powerful.

By anon31519 — On May 06, 2009

i read a lot of the posts up and one caught my eye... one anonymous said he/she thinks they found a way to use adrenaline on will but may be the reason for seizure disorder... i too have a seizure disorder and have been tested with no outcome just seizure disorder but also at the same time i feel like i too can pump adrenaline though my body... true it is bad for the heart though but it seems to be very addicting and i really want to get tested, mainly cat scan to see what part of my brain is able to do this and to find out if it really is an adrenaline rush or weather it is something else that may not be so harmful... pretty much, it may be possible for some people to do certain things with their bodies but most likely comes at a price (able to control adrenaline - seizure disorder)

By anon31091 — On Apr 29, 2009

Well yeah on one hand it's good to make you feel strong and that but I hate it when it makes a rash on my neck and cheek. Mainly the left side. It's embarrassing and people then know am nervous. I hate it as then I get even more embarrassed and aware of it and then I get dizzy and hot. Tell me how to stop it and don't say breathe deep and slow because then I will look even more a fool.

By md1117 — On Apr 22, 2009

well i don't know why anyone would want an adrenaline rush because that's just your body's response to a threat. i don't think you can activate adrenaline at will.

By anon30514 — On Apr 20, 2009

The called "Adrenaline" is also referred to medically as epinephrine. This is located just above the kidney's and can be used in many situations from a thought to a fight. These glands cannot be controlled or used at your own will. These glands let out epinephrine in these situations and flows them through the blood. Increasing oxygen to the lungs, muscles, and brain; to make you think, react faster with an increase in strength and agility. Again, these glands CANNOT be controlled, and when used, can be very harmful to the heart. The glands increase blood flow immensely and make irregular speed pump throughout the heart. Do not try and make your adrenal glands active at any given time for this can cause a long term effect on your heart. This is something that you should NOT mess with.

I'm 14 and the only time i ever get adrenaline rushes is in football. For me, my adrenaline rushes come from extreme anger that i intentionally put myself through so i can get through the line and make the tackle. I used to have many adrenaline rushes in football but i also couldn't control my anger very well. But now i can control my anger but i hardly ever get adrenaline rushes.

Now there's all these stories where people say everything slows down but it never really works that good for me. I don't really slow everything down it's more like i think faster, don't even feel any pain, and get increased strength. The only time it's slowed down is once or twice when i had to stop the offense or when i was so angry i thought my veins might pop even when i wasn't clenching my fists.

It's like everything that happened you remember and picture it as in slow-motion but it's really just that your mind is more focused at the time so you remember more of what happened in that little amount of time. I think this is probably because your eyes take time in as frames per second like a camera but when an adrenaline rush happens it's like a high-speed camera so your eyes speed up and take like double the frames per second so you remember and experience it like slow-motion but really your mind and body are just working double time. So like your body and mind do double the work in the same amount of time so to everyone else your quick and fast but to yourself your going slower because your mind is processing faster and your body is keeping up with your mind and working faster and harder. Your body goes at the same pace as your mind and the faster your mind is working and processing everything that happens by making your eyes take in more frames per second, the slower everything seems to you, and the quicker and faster you are to everyone else.

Does this give some insight into why adrenaline makes everything go in slow-motion?

Also adrenaline rushes come in the fight or flight response, so when you're angry i think it activates the fight response to strengthen your muscles and prepare you for a fight and flight response. It activates when you're in danger, or you definitely think you're in danger. In both cases you get stronger and your senses are heightened but adrenaline is an involuntary function and cannot be activated at will! You might be able to trick your body into a state where your body is ready to release adrenaline even when there is no real life-threatening danger but *don't do it*.

Adrenaline's function is to save your life in a life threatening situation and is not to be used as some super-power juice or whatever people might have in mind. Sure the feeling's good during the rush but it's bad for you and strains your heart. So adrenaline rushes are cool and all, but they can't really be activated at will even though you can make yourself get angry which might lead to one. Peace, hope this helps with some questions.

i remember having an incredible adrenaline rush. 2 years ago i was going to run against the fastest person in my city ( miami fl). it was a hundred meter dash. as soon as they shot the starting gun my heart was pounding & i couldn't hear anything. i felt like if i was going so slow but in reality my brain slowed down the entire world through my eyes. i was actually thinking while this was going on. in my head i was just saying 'wow i'm going to lose after i trained so hard' because i was going so slow. at the end i smoked him he got 10.8 and i got 10.3 btw i'm 14 when this happened i was 12.

By theshane0314 — On Apr 13, 2009

response to anon29094:

i can actually control what i see hear and feel. i can shut down or distort those senses at will. i can control what i see. i can just not see something. distort something that is there or cause myself to see something that is not that and i can do that whenever i want. i can also control my adrenaline. i can trigger it whenever i want to. i don't do it a lot though because i know the affects it has on my body. i can even control pain. i can make any pain just disappear just by thinking about it.

By anon29432 — On Apr 01, 2009

OK, so, i have adrenaline rushes all the time. lately, more often. you see, i play guitar hero a lot and every time i play a really hard song on expert like freebird or green grass and high tides, i get really exited and hit almost every note. after the song though, i have to run to work it off.

unfortunately, i just feel like smashing and breaking things. on a few occasions, i took it out on the nearest thing. my guitar controller. needless to say, it has cost me roughly $280. i disagree that you cannot access adrenaline at will, i do all the time. and also i'm stressed all the time about this girl i like. does the term heartbroken and the physical pain that comes with it relate to adrenaline?

By anon29094 — On Mar 27, 2009

You know you guys: *you can't control your adrenaline*!!! It would be equivalent to controlling your hair color - well not really, but you get my point! Your Adrenal gland is directly linked to your central nervous system, so it would be the equivalent to making yourself not see something that you’re looking at, or making yourself hear something that your listening too, it's completely up to you CNS! Now, if your CNS has something wrong with it, you might get adrenaline rushes often, but if you are fainting, you should see a doctor, adrenaline is *not* something to mess around with, it is *extremely* bad for your body and should only be used in fight/flight situations.

By andre999 — On Mar 26, 2009

I am 15 years old and I always have adrenaline rushes almost everyday. Is it normal? When I'm angry or irritated I am stronger. I think I can activate my adrenaline at my own will because when I'm running in a crowded area I can just easily pass through it, and I see all the people in slow motion, but after that sometimes my eyes hurt and they feel so hot. I can use it longer than any person I know.

By nblevins — On Mar 19, 2009

my chest hurts real bad after having adrenaline bursts.

i randomly have them while i'm trying to get some rest.

it makes me stand up and move.

i have been hitting my bedroom walls for years now.

sometimes this happens at school.

i hesitate, but for like a second and i react instantly. i've been having disturbing dreams. i have been having pains in my arms and legs like my muscles are being ripped of my bones and it hurts real bad. i had to go home from school in first period.

if anyone could give me some insight on this i would be grateful.

By anon28500 — On Mar 17, 2009

i can make myself have an adrenaline rush by trash-talking to an opponent or openly challenging someone competitively, then when it is my time to perform i focus on what i have told my opposition and "psych" myself into living up to my words. i also get an adrenaline rush if there is a crowd watching me or if there is someone i am trying to impress watching when i compete.

By anon28277 — On Mar 13, 2009

I love/hate adrenaline rushes. In the 8th grade is the biggest adrenaline rush I remember having. This kid behind me was scratching me on the back of the neck with his pencil. I was having an 'awful' day and once he scratched me the 2nd time my body immediately flared up, I started sweating, I could feel my temples flaming and I had thoughts off knocking him over the desk and constantly punching his face till you could no longer see his skin because blood covered it. Normal? What's scary is that I have the strength/ anger to do it. Restraining myself was near impossible. Is this a normal reaction to adrenaline? And could I produce this at will for instance in a soccer game?

By anon28223 — On Mar 12, 2009

Adrenalin is very bad for you, It harms the heart *greatly*. Adrenalin can't be accessed at will. It secretes mostly sugars from your stomach for energy, thus why your digestive track is suppressed and you may feel hungry afterwords. I've had plenty of adrenalin rushes, they made me feel superhuman at times, but the side effects aren't good in the long run. Examples of adrenalin, I ran about 100 yards in almost record time with an adrenalin rush. Your heart is damaged a bit because the irregular blood flow going through it.

By anon27738 — On Mar 04, 2009

I always get an adrenalin rush. it is very good. it is also a very good experience for the scientifically proven effect. i have been researching this for all my life very extensively and i have finally found the formula: C9H13NO3 *I love adrenalin*

By anon27656 — On Mar 03, 2009

I'm wondering about triggering this at will. Just for about an hour or an hour and a half. For a basketball game. I'm one of the better players in my county, maybe have a future, but i don't care. I'm trying to "experiment" with adrenaline for basketball games. Sometimes i'm unfocused, I need to be focused, I want to trigger it at will, could be fun.

By anon27444 — On Feb 28, 2009

Adrenaline rush isn't something supernormal as you may think, for example, people in panic have adrenaline rushes, and they can't think straight. So in many situations adrenaline rushes could be lethal.

By anon26989 — On Feb 22, 2009

Can someone tell me more ways to access adrenaline, because i can do it at will? When i get mad it also comes. I need to learn to control it.

By anon26792 — On Feb 18, 2009

Adrenaline is given in short bursts to your body because it is dangerous. It opens the blood flow to your muscles, but not without a side effect. Someone who ODs is said to be able to be saved by shooting adrenaline right into the heart. Would you shoot adrenaline into an active heart? No.

I've found in various sports and dangerous situations the period of time in which I had the adrenaline rush lasts only a couple of seconds, but after that rush a heightened feeling lingers. I believe this feeling is what people think about when they hear Adrenaline Rush.

It is said the 2 swordmasters would cross blades and that there would be a point of time for a single second that they claimed their blades seemed to have stopped. That is the point at which you have an adrenaline rush. It is not long. And not controllable.

By anon26666 — On Feb 17, 2009

want to try a short burst of it.. sit down and remember something really bad. a death of family,a fight etc. listen to music that pumps you up. and let out a shout. rampage all your feelings. breath heavy so more oxygen and reaches your muscles and flex them. you should feel a warmth over your body and breath slow until calm.

By anon26542 — On Feb 15, 2009

OK. First off let me start with activating adrenaline at will is no great thing. Yes I can do it, in fact I can control it by now so that it only pumps to one part of my body at a time. But that isn't good.

Your heart and kidneys can fail if you pump adrenaline for too long or too often. The longest I've gone with one rush is 6 hours and I was unconscious on the front lawn for 17 hours afterward. I ached and hacked up blood.

Yes you can condition yourself to pump adrenaline, but over time you can't control it anymore. Sometimes you'll wake in the middle of a good dream and have a rush or be sitting in class and all of a sudden, Bam, adrenaline. I'm 19 now, almost 20. I started to condition this about 6 years ago and I'm *just* starting to gain rudimentary control over it.

You are not super-human. Adrenaline is a wonderful thing but only in short doses. Don't play with it too much or you can kill yourself. Count yourselves among the lucky if you *can't* pump it at will. Just be warned.

OK so i'm 14, and i've had *some* adrenaline rushes before. They feel great, But, i've read all these posts and don't really get it. they all say different things.

does it cause abnormal strength? or is this just one cause of it? do people have different effects of adrenaline, or is everyone the same?

what if you could trigger it at will somehow? and some people say they can, but how?

By anon25659 — On Feb 01, 2009

OK well i'm 14 but i have noticed this over all of my fights. Why does everything get super slow and i am zoned out focused only on the opponent? Everything around me is a blur, but i can see the punch being cocked back and can react so quickly. Maybe this works when i'm really scared or mad. Well i really want to know it definitely works in fights, not that i start them. haha.

I have to wonder if there is, at least some way to "harmonize" with this hormone. I always thought of it as a liability, and not an asset.

What are the consequences of having your adrenaline gland surgically removed?

By anon24040 — On Jan 06, 2009

let me get this straight, you can access adrenaline at will?

By joliemaman — On Dec 04, 2008

I have discovered an interesting fact : i had an adrenaline as well as other hormones Imbalance/allergy. It has been corrected in 25 hours with NAET. I am not tired or stressed out anymore...

My friends and I used to do this thing where we all had obscure words and they were our "insanity words". Basically, whenever someone said your word you pretend to go crazy, running around really fast and/or saying random things. But later we found that this sort of conditioned our bodies so that whenever we wanted a boost we could get someone to say the word and we would get a rush. I'm not sure if it was adrenaline, but it sure does feel like it! If you want to see if it works, just come up with a word and tell your friends to say it. One of my good friends' words is 'nerds'. Mine is 'pacchinko'. It may be childish but it works for us. ;) Great article, very informative!

A Adrenaline Rush can't be fully copied and freely used. You have to be in a situation where you're in danger or when your extremely angry to have a full all out Adrenaline Rush. But you can get some Adrenaline pumping through your body by thinking of something that would piss you off. Some music can does this too. But I've been in some fights. My first one i had my first experience with a Adrenaline Rush. Your vision becomes clear. You lack the ability to hear. Your lungs open up. Making breathing easier. Your blood pumps through your body giving your body more strength and agility. And god does it feel good.

It's controlled by thoughts; sometimes of fear, sometimes of dire situations and sometimes even of anger. Just depends. Actually, I'm trying to learn how to keep it flowing; interests me.

So, if you're like me and you want to know how it's possible, think of fear, dire situations or anger, you'll get what you want; just need to think about it and pretend like it's a dream that you can control every move of.

i don't fully understand adrenaline, i mean what does it do to you?

By anon21372 — On Nov 15, 2008

believe it or not i think i actually have discovered how to pump adrenaline at will...im getting some tests done by neurologists to see if this is true because i thinks that's why i suffer from myoclonic seizure disorder, which i am taking medication for.

By anon19142 — On Oct 06, 2008

hi,i'd like to know what happen whether i was in a critical circumstance, but i could avoid this, and i didn't have you use that strength that adrenaline gives u, and instead of it, i ate something, ( chips) can happen anything? what i mean is, what happen with that sugar that travels through my body, and the sugar, that my body gets with the things i ate?

By burnett — On Sep 16, 2008

i would like to know that which chemical inside the body neutralizes the effect of Adrenaline??

By anon17936 — On Sep 10, 2008

Hey, I'm 15 and I've had a lot of adrenaline rushes in my life when i'm in tight situations, I know it pumps you up by a lot, but I would like to learn how to activate it at will. (Not with drugs or anything.)

By anon17927 — On Sep 10, 2008

how can you have an adrenaline rush by will?

By anon17366 — On Aug 28, 2008

Music makes me pumped or is that Adrenaline going through my body? could adrenaline poison you? Adrenaline makes me feel invincible and never tired i feel like i could do anything its awesome but at the sports carnival at school i get pumped when its my turn to run i bolt off at full speed with heaps of adrenaline running through me and then half way around the oval my whole body just locks down my legs feel like a ton and im so tired

By anon17275 — On Aug 26, 2008

I would just like to know if a drop in adrenaline would cause someone to be physically ill, like having cough cold and fever?

By theheat009 — On Aug 11, 2008

My friend says he can access adrenaline at will. I am somewhat skeptical about people who say they can access epi at will. But my friend's pupils dilate whenever he's in that "state". Why would this be? And can you access epinephrine to a certain point?

By anon16646 — On Aug 11, 2008

I was wondering, are things supposed to slow down when adrenaline gets released? I'm 14 now, but in a fight in 5th grade, the other kid had his hand around my throat, and everything gradually slowed down to an almost comical crawl. Afterwards, my extremities (fingers, toes) ached terribly. Is this a typical reaction, or is my body oversensitive to adrenaline?

By anon14963 — On Jun 27, 2008

I know Brazilian jiu jitsu, muay thai, american boxing and I am a certified personal trainer. I was also on my high school wrestling team. I'm just stating these to show the source(s) for the information I know. Adrenaline is not some super chemical that makes you super human. Almost all organisms on this planet have one form or another of an adrenaline rush. So all these claims of people beating up other people animals or ripping apart heavy large objects happened that way because these people are simply stronger then they realize. Also on a side note the 15 year old wrestling saying he has a "split spine" and that that makes him stronger, is a liar. What he is talking about is a debilitating deformity. If you have a cleft, split or double spine you can rotate/twist your body. you would have a rigid hard back that would have very little mobility.

Can adrenaline cause physical abuse?

By anon14831 — On Jun 25, 2008

Hmm, i know how to trigger it.. see im afraid of heights so when i close my eyes, and pretend im falling from the sky.. and im talking high in the sky while concentrating on pushing blood through the body .. soon i will feel this cold feeling rush through my body and i know its adrenaline..so basically just trick your mind into releasing it (btw ..>_> it hurt i couldn't feel my whole front side of my body and i couldn't stand)

By anon14376 — On Jun 16, 2008

Well, I'll call it getting "in the zone". It's that moment right before the gunshot where all the racers go silent and pay attention to nothing else, or the hunters bated breath before he pulls the trigger. You don't really call upon any "adrenaline reserves" or anything, but you prepare your mind for a state of stress, or put yourself into a state of stress in preparation for action. Your body does the rest. So it's really only a small bit adrenaline. Most of what you're feeling is just mental, not physical.

By anon14198 — On Jun 11, 2008

Hi i am a kid that can activate my adrenaline at will sort of. If I want to learn something really hard or do something really cool I just think about it calm myself down and i start feeling stronger and not just physically but mentally too. like i can act quicker and think quicker. Is this adrenaline or something else?

By anon10483 — On Mar 27, 2008

well, i've heard that the adrenaline can make you so much stronger and faster and agile than you normally are.

my father told me a story (which also he found out that he had some disease for a spilt spine, or 2 full spines in his back, which has to make me a lot stronger than a normal human being) he was driving home when he was about 18 in his Trans AM and he was doing about 110 down a windy road, pitch black out and he went into a pole at 120 at least which would of killed him, but the doctor has told him that he saved his life by pulling the entire front of the driver seat(steering wheel area) completely, which is very thick metal, and pulled the metal to block him from being killed. the doctor said that no possible human, even with adrenaline was able to do that.

I'm a wrestler, and one of my last matches was against a kid about 4x as strong and muscular as i was (he was like a richard sandrak when he was little) i had to go against him and i was able to toss this guy, he had me down about to pin me but seemed like he was trying to kill me too. once i felt that, i felt the adrenaline go through me and i was able to throw him off me and break the kids neck. he's now in the hospital or something of the sort, i had found out that i also have 2 spines at the age of 15

By anon10404 — On Mar 26, 2008

Probably not. I was wondering if a person without anaphylaxis was to use an EpiPen. Would it just feel like a strong natural rush of epinephrine or would it be dangerous?

But yeah, a rush in a soccer game makes you like, invincible. It's awesome.

By anon10044 — On Mar 18, 2008

is there any way (other than drugs or injections) to trigger the glands to produce adrenaline by yourself whenever you want? such as...say your in a soccer game and you need a boost of energy, would there be a way? and if so, would that be considered cheating?

By anon9330 — On Mar 04, 2008

So adrenaline is bad for you, I knew there was a reason the brain kept it from going regularly, I'll remember that next time I get into a situation.

By anon9250 — On Mar 02, 2008

I notice that when a highly stressed moment occurs, my left shoulder (had two rotator cuff surgeries in past) has an extreme shooting pain and then in 10-15 minutes it will pass. Why is that, what is in the adrenaline that causes this extreme pain?

Thanks Lou

By anon9153 — On Feb 29, 2008

I think adrenaline rushes through body when your brain thinks the body is in a life or death situation.

By anon8386 — On Feb 12, 2008

my son is 29. For the last 10 years, he has had gradual sleep deprivation because of uncontrollable anxiety at night (never during the day). In the last 2 years, his new physician and his (first) psychiatrist have diagnosed that his adrenaline functions like if he was running on a treadmill even though he is in a resting position.

So they prescribed him Seroquel (he is not bipolar), provigil, lorezapam for sleeping or waking up.

any comments?

By joliemaman — On Feb 08, 2008

If you feel like you are allergic to adrenaline or that you have an imbalance with your own adrenaline, explore a discipline called NAET. I have been cured by it from lyme disease, Vit B complex allergies as well as adrenaline and acid lactic allergies : it is immediate and without medications..

By anon7853 — On Feb 03, 2008

In one CSI episode, the murderer used adrenaline to kill his victims. How might this be possible?

By olittlewood — On Feb 03, 2008

that's a good question...i wonder not only do men produce more adrenaline than women, and how do men and women process/counteract adrenaline differently?

By anon7791 — On Feb 02, 2008

Is a man's adrenaline rush greater than a woman's adrenaline rush?

By anon7311 — On Jan 23, 2008

i can access my adrenaline any time i want but i can't get out of it until i wear it down. i do sports i am 13 almost 14 i don't know how i do it but i can and i love feeling the power run through me

By anon7135 — On Jan 18, 2008

i haven't had an adrenaline rush in years is this possible- i have narcolepsy and cataplexy, could this all be tied together?

By anon6763 — On Jan 08, 2008

that happens a lot to me

it happens whenever i want and i can't stop it

i think im just addicted to that feeling

By anon6288 — On Dec 22, 2007

Yes adrenaline hurts you!

That is why it's only supposed to be released when it is necessary.

It can wear down your body greatly, mainly your heart.

By theheat009 — On Nov 30, 2007

I know adrenaline is what your body uses for 'fight or flight' but is it always involuntary? I heard there are some, very rare people who can access their adrenaline at will. Personally I think that's false but I'd just like to make sure. Also does adrenaline hurt you in anyway?

By anon5043 — On Nov 10, 2007

what is meant by the term 'chemical cocktail' during the chemical reaction in our body during dangerous and unexpected situations?

How does adrenalin course its way through the body after it is released from its gland?
