Why do men have hair on their bodies?

The simplest: male hormones.

Men in general will have more body hair than women, which is the result of evolution.

And the body hair is not the same between men and men, some have very little body hair, some have a lot, why is that? Answer:Genetic inheritance。Everyone's hair follicles are different in their sensitivity to male hormones.

Some people think that men's body hair is particularly high because of excessive male hormones, but this does not exist. In fact, the male hormone required for the growth of body hair is relatively low, such as more than 200 ng dl, and body hair is fully expressed according to the genetic code。Men are very high in male hormones, at 500-1000ng dl, men do not increase body hair.

The thickness of a man's body hair has nothing to do with the level of male hormones

A woman's body male hormone is very low, will not exceed 80ng dl, can not reach the critical point of body hair growth, if her body male hormone reaches 150-200ng dl, then body hair begins to grow, but the amount of body hair that grows is related to family genetic inheritance, some women have very little body hair at this time, and some are very vigorous, the same as the male version.

Some women's hair follicles are abnormally sensitive to male hormones, and male hormones are more vigorous than men when their body hair is 40ng0 dl.

The amount of hair on the body of boys and boys is different, and the hair on the body is generally good for male hormone secretion. If you have too much hair all over your body, then you have to go to the hospital to see it.

Dizzy, I say! Nowadays, it is possible for the hair to be removed and no longer grow, such as laser hair removal (high price).

There are also some that can only be taken off for a while, but they will still be longer. In fact, as long as you don't care too much, you can adjust your mentality. Don't worry so much, I wish you a happy life!

Hair grows in **, the main role is to defend against the invasion of bacteria, can resist disease, and can also promote body perspiration, conducive to detoxification, prevent illness, may also lead to abnormal sweating, but also appear body odor, if excessive hair can be eliminated by laser.

If the temperature of the body is well regulated, it will form a good guarantee, under the strong exposure of the sun or in the cold season, there will be no serious injury, will not lead to allergies, and achieve the best perspiration system.

The function is that it can protect our health, protect our body, prevent bacterial infection, prevent dust from sticking to the body, and increase the roughness of the surface.

What does it mean that men have more hair? I believe we have all heard of the saying "a good man is hairy, a good woman is fat", this is our ancients through the observation of people, that the man with long hair on the body will be strong, and the woman is plump and round to be good for future generations, almost contrary to our current pursuit, now the creamier the more popular, the thinner the woman the more popular. However, from a health point of view, it seems that the ancients had some truth.

Why long hair: human body hair, in the past is the role of keeping out the cold and protecting the body, now with the reproduction and evolution of human beings, there are fewer and fewer people with hair on the body, but as they enter puberty, boys will grow hair on their bodies, some on the legs, face, arms, and chest, in short, due to the effect of male hormones, they will grow heavier hair, but there are also some boys who develop late, ** are also fairer, and the voice is relatively thin, and the voice is not comparable; However, although some people have not entered puberty, they also have hair, and even have hair at birth, this kind of person we call "atavism", in fact, it is similar to the phenomenon of recessive genes, and the characteristics that have evolved on the ancestors are manifested again.

In fact, atavism is not only reflected in the hair, many of us now have ears that can not rotate and move, but the atavistic people, his ears still have ear muscles, and the ears can also move slightly, I had such a little friend in the class when I was in school, and the body is also full of hair.

Some people may think that the long hair on a man's body represents that aspect is stronger, in fact, there is no basis for this, male hormones can only represent a person's male characteristics are more obvious, and atavism is even more unable to prove the strength of ability, but there is no need to care too much about these things, we know that there are "hairy children", in fact, the ancients admired people with developed hair, such as the beautiful haired public relations feather in "Romance of the Three Kingdoms", it can be seen that the ancients attached great importance to this aspect, but now it seems that they have not kept up with the times.

The hair on the face refers to the beard, and the growth of the beard is controlled by genetics, and it varies greatly from person to person. A man's face has more hair, which means that your facial hair follicles are sensitive to male hormones, which is written in the genes

As men age, their facial hair follicles become more sensitive to male hormonesTherefore, the older a man gets, the more beard he has, the thicker and thicker it becomes, which is embedded in the genetic code and is slowly and methodically expressed as he gets older

Some people who do not know the truth say that most of the beards on the face are strong male hormones, which is not true, and people who have few genetic facial beards, that is, people whose facial hair follicles are not sensitive to male hormones, will not increase their beards no matter how much male hormones they increase. Before the age of growing a beard, increasing male hormones will not make the beard appear early.

The first thing to consider is genetic inheritance, different women will have some differences in body hair due to different genetic inheritance, some hair is very subtle, and there seems to be no body hair; Some are a little longer, and the body hair is a little obvious. These are all normal, and if everyone is exactly the same, it is not normal and does not conform to the law of biodiversity.

On the other hand, it is also possible that endocrine disorders cause unnecessary excess body hair. Endocrine disorders are not necessarily high in male hormones, but may also be due to normal male hormones but low female hormones.

Women with endocrine disorders will also be accompanied by irregular menstruation, ** deterioration, poor mood, poor sexual performance, infertility and so on.

Therefore, if menstruation is normal and everything is normal and healthy, then it can be basically determined that it is genetically inherited, not that the hormone is high or low.

If it is an endocrine problem, then the first thought is that it is caused by polycystic ovary syndrome, because it is more common.

Other causes include adrenal hyperplasia or other abnormalities; insulin resistance; Corpulent; pituitary gland or hypothalamus abnormalities; Poor liver function, decreased detoxification ability, insulin imbalance; Poor digestive and circulatory ability of internal organs, poor metabolism, imbalance of gastrointestinal flora, inflammation in the body's circulation; thyroid disorders; Long-term stress and annoyance, etc.

Once an endocrine disorder is suspected, it can be arranged to be diagnosed in the endocrinology department of a regular hospital.
