How Goosebumps Physically Happen
- Goosebumps occur when tiny arrector pili muscles contract, making hair stand and skin pucker.
- The reflex is automatic and triggered by cold or strong emotions like fear and frisson.
Why They're Called Goosebumps
- The term 'goosebumps' comes from people noticing plucked goose skin looked like the bumps on human skin.
- Eating goose was common historically, so the resemblance made the name stick.
Two Main Triggers
- Cold and strong emotions are the main triggers for goosebumps because the brain activates the same automatic system.
- Emotions release adrenaline which switches on the reflex, producing chills or frisson from music or fear.
