A Reaction from Long Ago
We get goosebumps when tiny muscles at the base of our hair stand up. This happens when we feel cold, scared, or even excited. Long ago, when humans had more body hair, this reaction made the hair stand up to trap heat or make us look bigger to scare away predators. Today, we still have the same response, even though it doesn’t help us stay warm or look tougher as much as it used to.
How It Works
When something triggers goosebumps, our brain sends a signal through nerves to those tiny muscles, telling them to tighten. This causes the hair to lift and creates small bumps on the skin. It can happen from a cold breeze, hearing a powerful song, or feeling strong emotions. Goosebumps are one of the ways our bodies show what we’re feeling without us even saying a word.
