How to distinguish diseases from men's beards? Beard color is the key.

Men generally have beards, and judging men's health can start with beards. So, how can you tell the disease from a man's beard?

Seeing diseases from men's beards

1. Yellow beard

The color of beard is influenced by race and trace elements in the body. Most men in China have black beards, and a few have brown or reddish-brown beards. Modern research has found that the color of beard is determined by pigment cells, which are related to metal elements in the body. China men grow black beards because they contain copper, cobalt and iron, and red beards because they contain molybdenum.

If the beard turns from black to yellow, it may be a disease phenomenon.

First of all, iron deficiency anemia can cause male beards to turn yellow. Anemia is not a woman's patent, it can also happen to men. When iron deficiency anemia occurs, not only the beard turns yellow, but also other hairs on the male body surface tend to turn yellow.

Secondly, hypothyroidism and extreme malnutrition can also lead to beard yellowing. Extreme malnutrition is rare in modern society. hypothyroidism will not only lead to beard yellowing, but also lead to pale face, dull skin and hair loss. It will have a series of effects on endocrine system, digestive system and metabolic system.

2. The beard turned white

As we all know, with the beginning of aging, our hair will turn white, but if we are young, our beards will also turn white. Why?

First of all, the beard turning white may be a serious lack of metal elements in the body. As mentioned above, the color of beard is influenced by pigment cells, but pigment is closely related to metal elements. If the body lacks metal elements that affect pigment, a white beard will appear.

Secondly, kidney deficiency is an important factor leading to white beard in young people. In the thought of "eight men and seven women" in Huangdi Neijing, it is mentioned that men are "six or eight, the yang is exhausted, the face is burnt and white." It shows that the color of beard and hair is affected by kidney qi. Once kidney deficiency occurs, the beard will turn white or grayish white.

3. No beard

Some men also have no beard, but no beard depends on whether there is any disease.

First of all, if a man has no beard and other secondary sexual characteristics develop normally, then this is not morbid, which may be caused by the slow development of the individual. However, if there is still no beard after puberty, it can be regarded as an abnormal phenomenon and needs medical treatment.

Secondly, some acquired factors will also lead to men without beards, such as mental stress and poor mental state, which will lead to poor blood circulation, pore contraction and local beard death, thus leading to men without beards.

In addition, oil and honey are abundant, hair follicles are blocked in winter solstice, pores are enlarged, and hair falls loose. There will be no beard and baldness.

Four situations are not suitable for shaving.

1. No shaving in the morning.

In the morning, I got up in a hurry to shave. Before the afternoon, the stubble grew back. Don't worry, I'll introduce shaving tips to you and your family now.

Shaving time should be avoided. After a night's rest, the reproductive function is vigorous and the beard grows fast. Shave as soon as you get up, and your beard will grow back soon. After eating for 20 minutes to half an hour, the androgen in men is not so strong, and the growth rate of beards decreases. Shaving at this time will not grow quickly.

Don't shave immediately after washing your face.

Many men are used to shaving immediately after washing their faces or taking a shower.

If you shave with a blade, you'd better wet your face before shaving, because the beard will look hard when it is dry, and the blade will easily get stuck in the stubble, which may hurt or scratch your face. But the principle of electric shaver is different from that of blade. The electric shaver uses the principle that the motor drives the blade to move to cut off the beard or hair that enters the mesh of the shaver.

In this case, it is more suitable to shave off the upright beard or dry hair. After washing your face or taking a bath, the beard will be softened by water (the hardness will drop by about 30%), and it is easy to bend, and it is not easy to enter the mesh of the razor, so it is difficult to be shaved off. Therefore, if you use an electric shaver, it is best to shave when the beard is not wet, or when the beard is dry after washing or bathing, so that it is easier to shave the beard thoroughly and smoothly.

Don't shave after dinner

After meals, the stomach begins to digest, the heart rate increases, the blood flow increases, and the blood flows through the artery below the neck and face. Shaving at this time is easy to scratch the skin.

4. Don't shave before exercise

Don't shave before and after exercise, because at this time, the body will sweat a lot, stimulate the freshly shaved skin and produce a burning sensation.

Can you tell a man's sexual ability from his beard?

Studies have proved that the blood vessels supplying beard growth are more abundant than those at the root of hair, so beard grows faster than hair, with an average of about 0.40 mm per day (hair grows 0.27-0.40 mm per day). The stronger the male reproductive efficacy, the faster the beard grows.

The growth of beard is closely related to the secretion of androgen. The more androgens a person secretes, the longer and faster the beard will grow. However, the growth of beard is also influenced by another important factor, that is, hair follicle receptor. The more hair follicle receptors, the more "lush" the beard grows.

Due to genetic factors, everyone's beard is different, some are full of cheeks like Li Kui jy, some are dotted like Yan Qing, some are bearded like Guan Yu, and some are hanging by a thread like Sun Quan. Therefore, we can't judge a person's sexual ability simply by whether his beard is thick or not.

The scarcity of beard loss indicates a decline in sexual ability.

The number and length of a man's beard do not represent his sexual ability, but the change of beard state implies the change of his sexual ability. The bushiness of beard is mainly related to heredity, but the bushiness and sparseness of beard in different periods of the same person is indeed related to androgen, which is closely related to sexual function. It can be seen that the thickness of the beard of the same person in different periods is related to sexual function.

Therefore, if your beard becomes sparse or falls off completely, it is probably a sign of sexual dysfunction.

Three techniques for men to shave.

1, 20 minutes after getting up in the morning is the best.

This is mainly because when I first got up, after a night's rest, my reproductive function was vigorous and my beard grew fast. After eating for 20 minutes to half an hour, the androgen in men's bodies is not so strong, and the growth rate of beards decreases. Shaving at this time will not grow quickly.

2. Wash neutral soap first.

Cleaning before scraping is the last word. Wash your face with neutral soap before shaving. If there is dirt and dust on the face and beard, once the razor irritates or slightly hurts the skin, the dirt will cause skin infection. After washing your face, apply a hot towel to your beard, or apply a soft beard cream to soften your beard. After a while, apply shaving cream or soap to help the blade shave off the beard and reduce the irritation to the skin. When shaving, the skin should be tightened to reduce the resistance of the razor running on the skin and prevent the skin from being damaged.

3. It is better to scrape along the texture

Some men find shaving particularly painful. In fact, shaving needs to know the direction of beard texture. According to the different growth direction of facial beard, shaving cream has more time to soften the hardest part of short beard along the shaving sequence from left to right and from top to bottom, first along the pores and then against the pores. Scraping along the texture can reduce skin redness and pain.
