What is the function of armpit hair

Armpit hair is the hair that grows under the armpits. It is dark and thick, which greatly affects the appearance. It is especially hated by girls who love beauty. Especially in summer, in order to wear beautiful sleeveless dresses, they try all kinds of ways to remove the hair. Some people even undergo hair removal surgery to permanently stop growing hair and get rid of the problem. However, after thousands of years of evolution, every body organ must have its reason for existence, just like armpit hair. Let’s take a look at what the function of armpit hair is.

We say that men with armpit hair are sexy, but women with armpit hair are sloppy. So does that mean women must shave their armpit hair? Different people have different opinions on this question, but we might as well first look at the functions of armpit hair and the difference between shaving and not shaving, and then decide whether to shave your armpit hair or not.

Hair growth is related to androgens in the human body, so some people mistakenly believe that androgens are not possessed by women. In fact, normal women also have a certain amount of androgen in their bodies. This means that women generally have armpit hair when they reach adulthood.

Antibacterial. People have hands because they have functions. The same goes for armpit hair. Its existence is definitely not redundant. First of all, it has the same antibacterial function as pubic hair. It can shield and protect human skin from invasion by foreign bacteria, dust, etc., and keep the "enemy" out of the skin.

Relieve friction. In addition to preventing bacteria, another function of armpit hair is to reduce friction. Girls who are a bit overweight may have experienced this. In summer, they always feel uncomfortable after friction on the inner thighs, but this is not the case under the armpits because there is armpit hair there. The pubic hair on the inner thighs is not protected, so friction may occur.

The presence and distribution of hair on the human body is one of the ancestral characteristics that humans have retained as they evolved from apes to humans. On the body surface of a normal adult woman, except for the palms, soles of feet, the back of the distal ends of the fingers and toes, lip lines, nipples, inner sides of the labia majora, labia minora, and clitoris, there should be hair growing everywhere, but there are some differences.
