Chicken skin on girls' legs

Chicken skin on girls' legs

When the human body encounters cold wind, the human body will feel hairy for an instant, every pore will stand up, and small bumps will appear all over the body. This is called goose bumps. Most of them are the sweat in our body, so they will suddenly appear when the skin is stimulated, and disappear automatically after a while. What should you do with goose bumps on your legs?

People get goose bumps not only when they are cold, but also when they hear harsh sounds or see disgusting or scary things, their hair will stand up and they will get goose bumps.

Goose bumps have an obvious self-protection function for animals with long hair. When these animals are cold, their fur stands up and becomes fluffy, which can keep warm. The ancestors of humans, the ancient apes, were also covered with hair. During the evolution of humans, the hair has gradually degenerated, but the physiological function of goose bumps to keep warm has continued to be preserved.

effect:

1: Goose bumps appear on the skin. This is because human skin can regulate and maintain body temperature in addition to protecting our internal organs and excreting sweat. When the skin is stimulated by cold, the sensory cells under the skin will immediately notify the brain, making people feel cold, and at the same time, the arrector pili muscles under the sweat hairs will contract, making the sweat hairs stand up. At this time, the surface of the skin becomes very tight, forming a protective wall to prevent the loss of heat in the body. When the arrector pili muscles contract, they will pull the hair roots, so the sweat hairs stand up. To straighten the sweat hairs, the skin will be lifted up, thus forming small bumps, which look like chicken skin without hair, so they are called goose bumps. Goose bumps are a manifestation of the skin's self-defense function. It reminds people to "keep warm and be careful of catching cold". At this time, you should take warming measures immediately to avoid catching a cold.

Second: Goose bumps have an obvious self-protection function for animals with long hair. When these animals are cold, their fur stands up and becomes fluffy, which can keep warm. The ancestors of humans, the ancient apes, were also covered with hair.
