The current humans evolved from apes. There were no clothes at that time, so there were a lot of body hair on their bodies. The function of body hair can prevent mosquito bites in summer and resist the cold in winter.
With the continuous evolution of human beings, if there is too much hair, it may affect the body's heat dissipation. Gradually, it will decrease, but some of the hair is retained.
After so long human evolution, hair plays a very important role in this process, such as body temperature regulation, determination of DNA, etc. Some of the hairs left are not useless, they are good for protecting your health.

The role of body hair
share several body hairs that are easily disliked by people, and they play their unique value to the human body.
Leg hair
Someone has thick body hair on their legs. After sweating, the existence of leg hair increases the contact surface with the air, which can take away sweat from the skin faster, which is also beneficial for protecting the skin. Therefore, leg hair helps the skin dissipate heat and evaporate sweat.
nose hair
nose hair can filter the air inhaled, isolate the bacteria and dust in it from the outside of the nasal cavity. Moreover, because of the existence of eyebrows, these substances will not irritate the nasal mucosa , reducing damage to the nasal cavity and respiratory tract, and are also helpful in protecting the respiratory system.
armer hair
s sweat glands are very rich in 1 month. Armpit hair can help guide sweating and also help prevent bacteria. When walking, swinging armpit hair helps reduce friction. Body odor is related to genetics and has nothing to do with armpit hair, so don’t shave arming hair casually.

: Armpit hair
Many women hate armpit hair very much, especially in summer, in order to make themselves look cleaner, they will shaved armpit hair, but it is not recommended that you shave armpit hair, because armpit hair has a lot of effects.
There are many sweat glands under the armpits, and the axillary hair helps evaporate sweat. Secondly, the armpits are prone to friction, and the presence of armpits helps reduce friction. Finally, there are more lymph nodes under the armpits, and the presence of armpits can protect the lymph nodes from infection.
So we should try our best to keep armpit hair, and it does not mean that there is armpit hair, it is a sign of sloppyness. I hope women can pay attention to it.
2: Eyebrow
Eyebrow has the effect of blocking sweat. Sweating is a normal physiological phenomenon in humans. It will cause sweating when the weather is hot, exercise, and after eating spicy food. When the sweat flows down, the eyebrows will block sweat and divert sweat to the nose and cheeks to protect the eyes from irritation and damage. In addition, eyebrows can also prevent dandruff and wind and sand.
Eyebrows can also help people improve their appearance. If their eyebrows look good, their facial features will look more delicate, so many women will outline and draw their eyebrows when putting on makeup. However, it is not recommended for women to shave their eyebrows, because it is not conducive to the health of their eyes and will also affect their temperament and appearance.

endocrine disorder
If there is an endocrine problem in women, it will also lead to excessive body hair. This situation usually causes more hair around the lips, front chest and other parts to become more and more wider.
Ovarian lesions

If the ovary has lesions, such as polycystic ovarian disease, it will cause problems with hypothalamus regulation, resulting in excessive body hair. Especially the hair on the arms, calves, mid-abdomen and other parts will be more vigorous.
