Why do we get goosebumps?
When threatened, our bodies try to make itself as large as possible, mainly by erecting your hairs. When cold, a similar process happens, except it is to trap heat.
i dunno but its cool and feels wierd lol
It's probably because it's just a nerve or a habit for your body.
Might be because of the change in temperature within your body or surroundings.
Happen make you excited
Your nerves are trying to get your body back to the normal temperature at which it should be
When you are cold your skin tightens to make you warmer but the hair bud things stay so those are the goose bumps.
I know!!! I asked this before! Your skin tries to get really thick when you feel threatened. That's why in movies or books people say "I felt a shiver down my spine."
