Most people at one time or another will get goose bumps. It’s a strange thing that happens to people's skin.The muscles at the bases of the hairs on your skin get very tense and they contract, much like your bicep muscle does when you flex your arm.These little muscles make tiny bumps all over our skin and these are called goose bumps.here are quite a few things like goose bumps that our body does without us thinking about them. These are called reflexes. If a doctor taps your leg right below your knee and you kick your leg, that’s a type of reflex. Also, sneezing because something tickles your nose is a type of reflex.
