US, WASHINGTON (ORDO NEWS) — The reflex that our ancestors needed was still needed by animals, but it was practically useless for modern man.
Human skin is almost everywhere provided with numerous hair follicles. Each of them is a muscle that lifts hair. When these muscles contract, pimples appear on the skin of a person at the base of a small hairline. They are called “goose skin” for their similarity to the skin of a plucked goose. Moreover, even if hair does not grow in some parts of the human skin, follicles are still there and working.
“Goose skin” (or, in scientific terms, pilomotor reflex) is needed by animals, for example, monkeys. In danger, the hair on their body rises, the animal looks larger than it actually is, and such a transformation can frighten the enemy.
The porcupine is famous for its pilomotor reflex. As a result of the contraction of numerous muscles, spines (modified hair) on his back rise when danger occurs. The sight of the porcupine becomes awesome.
With a person such a transformation does not occur. On the contrary, “goose bumps” betray a person’s fear, which he might like to hide. The “goosebumps” that appear in humans at the time of danger are essentially worthless. However, a pilomotor reflex caused by cold makes sense. The fact is that with the tension of the muscles lifting the hair, heat is released. Due to this, a person warms up.
