Goosebumps, or piloerection, aren’t just a response to cold; they can also be triggered by emotional stimuli, like music, fear, or awe.
This phenomenon occurs when tiny muscles at the base of hair follicles contract, raising the hairs on our skin.
Evolutionarily, this was meant to make animals appear larger to predators or to keep warm, but in humans, it’s a sign of deep emotional response, showing how closely linked our physical and emotional states can be.
