How goosebumps form

Goosebumps form when adrenaline causes contractions of tiny muscles attached to each hair. The muscles pull the hairs up and the hairs pull the skin.
you can also get goose bumps when you get a chill from your thrill. Being afraid can make You sweat..which cools you off. The raised hairs that produce goose bumps are an attempt to trap air and body heat
