whydo i get goosebumps?

Answer 1

Self defense mechanism.

Answer 2

Little muscles get impulse from the brain to elevate your hairs (on your head, all over the body). Why does the brain think this is necessary? That's the right question.
This is an evolution leftover. When your cold you got goosebumps to keep you warm. But this doesn't help because WE DON'T HAVE FUR ANY MORE. Goosebumps are also associated with feelings like pleasure, or fear.
It's same as some cat reactions.
In the further evolution we will probable lose this ability (and eventually lose our hairs too).
So enjoy, while you still have it. :)

Answer 3

You get goosebumps from the control of the piloerector muscles at the base of each hair in response to signals from the autonomic nervous system. When we shiver to create warmth, our hairs stand on end to try and slow air circulation near the skin, limiting evaporative cooling. Interestingly, the same type of response is also created during fearful or emotional circumstances.

Answer 4

Goosebumps are caused by the coldness in weather or being in a cold place and it produces the goosebumps.

Answer 5

you get goose bumps when you're cold or are experiencing strong emotions like fear - for instance, you get goose bumps while watching a horror movie or when you've showered and stepped into a really cool (as in cold) place and stuff.
goose bumps are created when tiny muscles at the base of each hair, known as arrectores pilorum, contract and pull the hair erect. the reflex is started by the sympathetic nervous system, which is in general responsible for many fight-or-flight responses.

each goosebump is a hair root and when you get cold or excited the hair folical contracts making the skin rise.... therefore you have goosebumps...
