Understanding Goosebumps

The video explores why humans experience goosebumps, a reflex known as the piloerection reflex. It occurs when tiny muscles at the base of hair follicles contract, causing hair to stand up and skin to form bumps. This reflex is shared with animals like porcupines and sea otters, who use it for protection. Goosebumps are triggered by cold or strong emotions, and the term originates from the resemblance to plucked goose skin.
