Why does everyone have hair on their bodies?

Darwin's On the Origin of Species says that man evolved from monkeys.

The monkey has a lot of hair, and Sun Wukong grabs a handful of hair and blows to become a large group of small hairy monkeys.

Compared with the monkey, there is very little hair on the human body, in fact, the pores are still there, and the hair degenerates in most places and cannot be seen by the naked eye.

Human hair is related to genetics and hormones secreted by the body, the existence of hair is mainly for sweating, helping the body to dissipate heat and discharge toxins from the body, and some drugs can also enter the human body through sweat pores.

The hair on the body is collectively referred to as body hair. It is made up of layers of keratin proteins. Some organisms on the earth change their body hair due to the change of seasons.

Organisms have different body hairs, and even for the same species, the color of the body hair, and the growth rate of the body hair will not all be the same. Part of the creature, its body hair has the function of warmth, detection, camouflage.

Everyone has hair on their bodies, such as armpit hair, leg hair, and hair ...... there

In fact, this is a passage from a song called "Brother Mao Mao", the lyrics of this song are all related to Mao, and the whole song is explaining that everyone has Mao on their bodies, telling the importance of Mao Mao, and later it was spread to Douyin, and it became popular.

Everyone has Mao Mao on their bodies, I ask you to sing Mao Mao?

Hair on the human body is a legacy of human evolution. In the course of human evolution, hair has played an important role in maintaining body temperature, protecting**, and providing sensations. Here are some of the main reasons about the presence of human hair:

Protection**: Hair can provide some protection against dust, bacteria, and other harmful substances from entering**. For example, hair protects the head from sunlight and heat loss, and eyebrows and eyelashes protect against sweat, water droplets, or particles from entering the eyes.

Maintain body temperature: Human hair helps maintain body temperature balance. Hair can provide an insulating layer when it's cold, reducing body heat loss. When we feel cold, the body creates an insulating layer by making the hairs stand up (goosebumps) to maintain body temperature.

Perception of the environment: Hair can increase the presence of the outside world. For example, the fine hairs on the hair and body are able to sense slight changes in touch, wind, temperature, etc., helping us to react to the external environment.

The hair on the body may be related to genetics, and there is also a possibility that the secretion of male hormones is too vigorous.

At the beginning of human evolution, people also had very thick hairs on their bodies, which could help maintain a healthy body temperature and avoid cold. But after continuous evolution, with clothes and shoes, the existence of some body hair has lost its value, and slowly the vast majority of people's parts have lost their thick hair.

Leg hair, body hair on the arm: It plays a certain protective role, and can block the direct bite of dust, bacteria and mosquitoes from the outside world, and plays a certain protective role. And because of the presence of leg hair, it can help dissipate heat and cool down the human body.

If a woman has high body hair, polycystic ovary syndrome is considered. Polycystic ovary syndrome is characterized by amenorrhea, obesity, infertility, acne, hirsutism and other characteristics, if you find that your body hair is particularly upward, then you can go to the hospital for endocrine testing to see if there is polycystic ovary syndrome. If you are overweight and have menstrual disorders, then the vast majority of people have polycystic ovary syndrome.

The test is on the 2nd 5th day of menstruation, fasting in the morning, going to the hospital before 10 o'clock to draw blood for endocrine testing, or going to the hospital to do color ultrasound, color ultrasound can also indirectly determine whether there is polycystic ovary syndrome.

There is a lot of hair on the body, which is thought to be related to male hormone secretion or genetic factors. If male or female friends feel that the hair on their body affects their image and appearance, male or female friends can go to a regular hospital and adopt a suitable method according to their own situation and the doctor's advice**, such as laser. Usually, male or female friends can also remove hair through hair removal products.

Usually, it is recommended that male or female friends eat more radishes, greens, rape leaves, spinach, kale, Chinese cabbage, cabbage and other vegetables, sweet potatoes, potatoes, corn, buckwheat and other coarse grains, these foods help regulate endocrine. Also, reduce your intake of finely processed breads, cakes, as well as beverages and junk food, and limit your fat intake.

After these two tests, a definitive diagnosis can generally be made based on the results of the two tests, and then the symptoms can be corrected based on the results of the tests**. It is recommended to go to the endocrinology department to improve the relevant examinations, and after clarifying, under the guidance of the doctor, formulate a targeted plan for the corresponding **.

The hair on the body is mostly related to the individual's physique, and it also has a lot to do with genetics, and now boys are generally very well nourished, so the body hair is relatively heavy, which is a normal phenomenon.

What do you mean? Is it on oneself or on clothes? If it's clothing, it's probably that you've come into contact with some animals. If it's on its own, it may be because some of the body's nutrients are too lush.

Excessive hair, also known as hirsutism, is caused by androgens. The severity of hirsutism depends on the amount of androgens and the ability of hair follicles to respond to androgens.

Why do I have so much hair on my body? I think that the hair on your body is more than that, which is why you have hair on your body.

The main reason for the large body hair on the body is genetics, that is, the hair expressed by the inherited genes grows luxuriantly, and if the parents' body hair is more vigorous, the child is prone to grow more vigorous hair. There are also people with different regions and races, so they show different hair lengths, such as Asians, Europeans and Africans, and the content of body hair is different. The level of hormones in the body, especially androgens, if the content and proportion are high, the thickness of this hair that appears is noticeable.

Of course, there are some acquired conditions, such as ** problems, **itching, dermatitis, long-term topical hormone ointment in one area, one of which will be the aggravation of body hair. If you have a chronic disease that requires oral hormones, you need to take hormone drugs for a long time, which will also affect the hair on your body more than before.

If you have a lot of hair on your body, you can buy a shaver and shave it.
