Why do we shake when we're nervous?

Question

I was really nervous when i met all of favourite band and i my hands we're shaking.

Answer 1

Because you are still when you are not nervous...

Answer 2

a rush of adrenaline can make you shaky

when you're nervous/excited, you can get an adrenaline rush, and if you don't have any way to release that energy (running for your life, performing, etc), it can make you shaky.

adrenaline is similar to caffeine... you may have noticed the same shakiness when you have too much coffee.

Answer 3

Its because your adrenaline gland is pumping adrenaline into your bloodstream. Adrenaline is the strongest type of energy, it make you do things you've never thought you could. If you can only lift about 70 lbs. you can now lift 140 lbs, you can lift twice what you normally can, run twice as fast as you normally do, and it shuts down all intestinal functions.

Your body shakes because your mind is contemplating wheter to defend itself and take a risk or run away. It's called the fight or flight instinct. Your body never goes down without a fight, so you shake to wake yourself up pretty much. It makes you aware that you are not stable now, that adrenaline is going through your body to help you. The amount you shake also depends on how much oxygen you take in, oxeygen is energy too, with all that energy bundling up inside you it needs to waste the excess so you get goosebumps and you shake.

Sometimes you shake when your nervous because your mind actually can't beleive what's happening, like when you met your favorite band you couldn't understand that it was actually happening so your mind is trying to prepare your body for something you've either liked or wanted for a long time.

Shaking is the bodies easiest way to tell your nervous, other then pupil dialation, goosebumps, uneasiness and along with sometimes nuasioutious feelings, shaking is your bodies normal response to something big or amazing.

Answer 4

The world may never know

Answer 5

i think fighting yourself and how you truly feel.. the way media bigs up these people and such.. and maby the power they have.  but it's so socially unacceptable to behave the way your body heart and mind and pelvis region actually wants to behave that your body will shake.. it's almost like a self defense system your mind subconsciously puts into play

Answer 6

It's an automatic defense mechanism.

Answer 7

whats the band?

[e-mail]    e-mail me.

Answer 8

I have seen dogs do this especially when cowardly dogs are being threatened. They quiver all over. It is just normal when you are highly excited.

Answer 9

I shake then I rattle,then I roll.

Answer 10

Because when you're afraid or just nervous, your body goes into "defense mode". Your body shakes so that your muscles are prepared to either "attack" or to "flee" a dangerous situation. It's a survival instinct we're born with, but it can be embarrassing at times. There's nothing wrong with you...

Stress: The Fight or Flight Response





What is the fight or flight response?



The flight or fight response, also called the "acute stress response" was first described by Walter Cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system. The response was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms.



The onset of a stress response is associated with specific physiological actions in the sympathetic nervous system, primarily caused by release of adrenaline and norepinephrine from the medulla of the adrenal glands. The release is triggered by acetylcholine released from preganglionic sympathetic nerves. These catecholamine hormones facilitate immediate physical reactions by triggering increases in heart rate and breathing, constricting blood vessels and tightening muscles. An abundance of catecholamines at neuroreceptor sites facilitates reliance on spontaneous or intuitive behaviors often related to combat or escape.



Normally, when a person is in a serene, unstimulated state, the "firing" of neurons in the locus ceruleus is minimal. A novel stimulus, once perceived, is relayed from the sensory cortex of the brain through the thalamus to the brain stem. That route of signaling increases the rate of noradrenergic activity in the locus ceruleus, and the person becomes alert and attentive to the environment.

  

If a stimulus is perceived as a threat, a more intense and prolonged discharge of the locus ceruleus activates the sympathetic division of the autonomic nervous system (Thase & Howland, 1995). The activation of the sympathetic nervous system leads to the release of norepinephrine from nerve endings acting on the heart, blood vessels, respiratory centers, and other sites. The ensuing physiological changes constitute a major part of the acute stress response. The other major player in the acute stress response is the hypothalamic-pituitary-adrenal axis.

Answer 12

i think its cos of the excess adrenaline being produced, your body wants to run away but you stop it and so the energy gets used up through your shaking instead of running

Answer 13

you get goosebumps which cause you to get the shivers it's like why do you laugh sometimes when ur nervous

it's one of those things wich is hard to explain

Answer 14

It's just our body's response to our emotions.

Answer 15

in the past we were getting ready to retreat

Answer 16

not everyone shakes its your own reaction to nervousness.
