Overview
Everyone experiences goosebumps from time to time. When it happens, the hairs on your arms, legs, or torso stand up straight. The hairs also pull up a little bump of skin, the hair follicle, up with them.
As you may have noticed, goosebumps tend to form when you’re cold. They also form when you experience a strong emotional feeling, such as extreme fear, sadness, joy, and sexual arousal.
Goosebumps may also occur during times of physical exertion, even for small activities, like when you’re having a bowel movement. This is because the physical exertion activates your sympathetic, or instinctual, nervous system. Sometimes, goosebumps may crop up for no reason at all.
Many animals also experience what could be categorized as goosebumps, including porcupines and dogs. In these cases, goosebumps are a bodily response to situations where it’s advantageous to appear larger and stronger, such as during a confrontation or courtship.
In humans, experts believe goosebumps are a product of evolution working in a similar way as they’re meant to in nonhuman animals.
On the most basic level, goosebumps can help keep you warm. When you’re cold, the muscle movements that can trigger goosebumps will also warm your body.
In animals, this action also raises hairs in a way that traps air to create insulation. In people, this effect doesn’t do quite as much. Humans have much less body hair than many other nonhuman animals with hair.
In most cases, goosebumps are nothing more than a temporary nuisance. However, goosebumps can be a sign of a long-lasting or serious medical condition. For example, goosebumps can also be a sign of:
•Keratosis pilaris. A harmless and common skin condition that creates the look of goosebumps on the skin for long periods of time.
•Autonomic dysreflexia. An overreaction of the nervous system caused by a spinal cord injury.
•Temporal lobe epilepsy. A chronic seizure disorder.
