Goosebumps that appear on a person's skin are small bumps at the base of the hairline. This effect occurs involuntarily and cannot be controlled by a person in any way.

Reasons for the appearance of "goose bumps"

Goose bumps appear absolutely involuntarily when the body is cold or is exposed to very strong emotional arousal. This happens when a person experiences fear, awe, admiration, or sexual arousal. This can be called a reflex response of the body to surrounding stimuli or a burst of emotional activity.

The process leading to goose bumps is called the pilomotor reflex. When the sensitive peripheral nerves that emanate from the spinal cord are stimulated, the autonomic peripheral nerve endings are stimulated, and the smooth muscles of the hair follicles contract. By contracting, they raise the hairs on the body - this is called the piloerection effect.

In people, this effect can be caused not only by fear or cold, but also by other emotions: a sense of satisfaction or pleasure, for example, from listening to beautiful music or, conversely, from sounds that cause disgust - the grinding of metal on glass or chalk on a board.

Due to the limited amount of hair on the human body, the effect of piloerection can be called rudimentary, that is, it has lost its practical meaning.

Goosebumps can occur after prolonged squeezing of nerves, with a lack of vitamins or metabolic problems.

Goosebumps can mean poor circulation in the limbs.

But in most cases, goose bumps are an indicator of a person's mental state. This feeling is often inherent in suspicious and anxious people.

Interestingly, the name "goose bumps" really came from a comparison with goose skin. Geese feathers grow from seals that are very similar to human hair follicles.

Pilomotor reflex in mammals

The "Goosebump" effect is manifested not only in humans, but also in many mammals. When reacting to danger, the hairs on the animal's skin rise, making it more massive and intimidating.

When reacting to cold, the hairs also rise and help maintain warm air inside the coat, thereby warming the animal's body during cold seasons.

Nature has endowed animals with this reflex for various purposes. The porcupine uses this effect to force the thorns all over its body to take a defensive position. Mice, cats and dogs use the pilomotor reflex during fear or extreme irritation, and this is also the case in chimpanzees.
