What are goose bumps about?
Goose bumps occur when the tiny muscles at the base of each hair follicle tighten and pull the hair upright. “It’s actually a reflex triggered by the sympathetic nervous system, which is responsible for many fight-or-flight responses,” says Dr. Priya S. Gupta of Johns Hopkins Children’s Center.
That’s why goose bumps commonly occur when you’re nervous or scared, as well as when you’re cold.
