The formation of goose bumps in humans under stress is considered by some to be a vestigial reflex, [4] though visible piloerection is associated with changes in skin temperature in humans. [5] The reflex of producing goose bumps is known as piloerection or the pilomotor reflex , or, more traditionally, [ 6 ] horripilation .
Jul 30, 2018 · In addition to the above, there is an autonomic mechanism yet to be systematically investigated in terms of volitional control –piloerection, often referred to as ‘goosebumps.’ Involuntary piloerection is commonly observed during cold, fearsome, or intensely evocative emotional stimuli, and is subserved by the pilomotor projections of the sympathetic nervous system (SNS).

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.
Oct 2, 2020 · Other medical terms for goosebumps are horripilation, piloerection, or the pilomotor reflex. Each of these terms describes a temporary change in the skin from smooth to bumpy, most commonly developing after exposure to cold. Many people associate goosebumps with fear, or perhaps more accurately, with horror.

Mar 16, 2024 · Goosebumps, also known as piloerection, are a common bodily reaction that most people experience when they are cold, frightened, or even emotionally moved. While we often associate goosebumps with these everyday sensations, they are a much more complex response involving intricate physiological processes and deeply rooted evolutionary mechanisms .
