Goosebumps are the result of tiny muscles flexing in the skin, making hair follicles rise up a bit. This causes hairs to stand up. Goosebumps are an involuntary reaction: nerves from the sympathetic nervous system — the nerves that control the fight or flight response — control these skin muscles. In the animal kingdom, a threatened animal has a si...
Researchers studying mice recently linked goosebumps to the regeneration of hair and hair follicles. It seems that the nerves connected to the tiny muscles responsible for goosebumps also connect to hair follicle stem cells, which are the cells responsible for hair growth. So, in response to cold, the nerve tells the tiny muscles in the skin to con...
Goosebumps may help you conserve heat when you're exposed to cold. They may do this in several ways. 1. As with larger muscles, contraction of the muscles in the skin (called arrectores pilorum) generates heat. 2. The raised hair follicles cause skin pores to close. 3. Hairs standing up trap a layer of air near the skin, holding onto body heat. Eac...
Most people associate goosebumps with unpleasant situations, such as feeling particularly cold or feeling afraid. Yet there is more to it than that. The arrectores pilorum are hooked up to the sympathetic nervous system, and the sympathetic nervous system has input from many parts of the brain, including those involved with motivation, arousal, and...
Though rare, goosebumps can be a sign of a seizure disorder called temporal lobe epilepsy, a disorder of the sympathetic nervous system, or other brain disorders. They are also common during heroin or other opiate withdrawal. In fact, one explanation for the origin of the expression"quitting cold turkey" is that goose bumps that develop during with...
You'll see goosebumps most often when you're cold. But don't be surprised (or afraid or awed) if they appear at other times. They are a universal but poorly understood phenomenon, but our understanding is improving. And the recent discovery linking goosebumps with hair follicle regeneration could lead to more than just a better understanding of goo...

Jul 28, 2020 · Goosebumps occur when tiny muscles in our skin’s hair follicles, called arrector pili muscles, pull hair upright. For animals with thick fur, this response helps keep them warm. But it doesn’t do so for people. Still, this ability to make goosebumps persists in humans and other animals that don’t have enough hair to retain warmth.
