Goosebumps are a state of the skin caused by cold, fear, or excitement
Most people know what a goosebump is. But for those who don’t, here is a breakdown. Ever watched a scary movie, and you suddenly feel a chill, and then you see little spots rising on your skin? Those are goosebumps. The question is, how do they form?
Goosebumps result from a contraction of a minimal muscle attached to each hair. Each of those muscles causes a shallow depression on the skin’s surface, which then causes the surrounding area to protrude.
