“I’ve got chills, they’re multiplying,” — we all know the feeling. We experience goosebumps in many different settings; when your favorite beat drops, when you get an eerie feeling, and of course when you do not feel well. But what do they goosebumps actually signify? Where do they come from? “William Griffith, PhD, professor and head of the Department of Neuroscience and Experimental Therapeutics at the Texas A&M College of Medicine, said goose bumps are a normal biological response to powerful emotions from dramatic or stressful situations linked to fight-or-flight. “Fight-or-flight is in response to something, typically being scared, shocked or encountering a predator, that prepares us to fight or flee,” Griffith said.” This adrenaline release is also triggered by strong emotional responses we have to certain situations.
This release is caused by a perceiving threat, which activates a surge of energy that prepares the muscles to act quickly. “These hormonal releases also cause the arrector pili muscles that surround the individual hair follicles to contract, making the hairs to stand on end and causing goose bumps,” Griffith said.
