What does the high frequency of shaving in men indicate? How is it related to lifespan? tell you with research

What factors are related to human lifespan? Many people believe that the length of lifespan is affected by living and eating habits; but it has also been suggested that men's lifespan is related to their usual shaving habits. Some medical studies have found that women tend to live longer than men, and women account for a higher proportion of long-lived elderly, which may be due to the lack of beards in women.

Is male longevity related to shaving? Men often shave their beards in life, what does it show? Let's find out together.

1. About the beard

Why do men grow beards?

Beards grow when male hormones in a man reach a certain level. From puberty, the testicles of men will continue to secrete large amounts of androgens, and the adrenal cortex in the male body will also secrete androgens.

The continuous secretion of male hormones in the body will speed up the development of the secondary characteristics of the male body, so men will grow hand hair, foot hair and beard, which is a normal physiological phenomenon of the human body.

Body hair grows more vigorously in men than in women. The higher the level of androgen secretion in the male body, the faster the growth of the beard.

With the aging of the body, the normal function of the male testicles also decreases, and the secretion level of androgens in the body decreases . Therefore, after men enter a certain age, the growth of beards will be relatively sparse, which is a normal phenomenon and does not require treatment.

What does a beard do?

Beard is one of the manifestations of male secondary characteristics. When the body is stimulated by androgen, it will grow beard. Beards may not seem like they do much for good health, but they protect a man's face from harm.

Generally, beards can resist the changes of seasons and weather, protect men's skin from UV damage, and avoid dark spots on the skin due to sun exposure; and men's beards can also reduce the probability of skin diseases.

2. According to the shape of the beard, it may be possible to judge the health of the body

1. The beard grows too fast

If the male hormone secretion level is high, the beard will grow too fast . A healthy male with normal endocrine growth will grow about 0.4mm every day. If a man finds that his beard grows too fast, he just shaved it the day before, and it grows back quickly the next day, and it is dense and black, with a new length. Much more than 0.4mm, indicating that the level of male hormone secretion in the body is too high.

Whether the secretion of male hormones is too much or too little, it is not good for health, and the human body needs to maintain a balanced and normal secretion level. If the male hormone secretion level in the male body is too high, adolescents will have precocious puberty, and the body hair will grow too fast, and the body hair will be very thick. If there is too much male hormone secretion in the body, it will also cause the secretion of oil in the body to be too large, which will block the pores.

2. Beard color change

With the aging of the human body, the beard will turn white, which is normal, but if the beard turns white abnormally when the man is young, this is not normal. If a man's beard is black, it means that there is sufficient nutrition in the body, which can provide enough nutrients for the growth of the beard, and the body is in good health.

If the beard turns white abnormally, it may be caused by physical damage. At this time, you need to pay attention to your physical health and determine whether it is caused by the damage of the digestive system, the malabsorption of nutrients in the body, or due to physical fitness. Decreased, premature aging symptoms caused by physical weakness.

Some men's beards will appear red or yellow , which is caused by the lack of nutrients in the body. If the beard is abnormally red, there may be a lack of trace elements in the body; if the beard turns yellow, the body may lack copper or have symptoms of anemia.

3. Sparse beard

The density of beard growth can reflect the health of the human body. Whether a beard is too thin or dense, it is unhealthy. As men get older, their beards will become thinner when they enter old age, but they rarely fall out on their own.

Many men are thankful when they find that their beards are thinning or falling out, so they don't have to shave as often, but this is actually wrong. When this happens, it means that we should pay attention to the conditioning and maintenance of the body. When the level of pituitary hormone secretion in the human body decreases, the secretion of male hormones in the body will decrease, so there will be thinning and shedding of beards.

If the level of androgen secretion in the male body is low, and the secondary characteristics of males are weakened, it will seriously affect the health of the body and lead to the reduction of body functions. Therefore, when such phenomena occur, the body should be conditioned in time.

4. The beard has a hard texture

The strength of male fertility can be judged by the softness and hardness of male beards. In adolescent males, beards tend to be softer and thinner, but with age, beards tend to become thicker and harder.

After many men become fathers, their children will obviously feel that the father's beard is very hard. When this happens, it means that the male has high physical fitness and good physiological function. Conversely, if the beard is thin and soft, it indicates poor physiology.

Reasons why men frequently shave

The growth rate of male beard is related to the level of androgen secretion in the body. The amount of hormones secreted can affect the growth of the beard. When males have high levels of androgen secretion, these groups tend to grow beards faster.

The growth rate of beard is also affected by the factor of staying up late. Staying up late will increase the sensitivity of skin hair follicles to androgens, which will cause the human body to grow beard rapidly, and the growth rate of beard is also related to the frequency of shaving and shaving. When you shave your beard, it stimulates the hair follicles in your skin and makes your beard grow faster.

In addition, due to factors such as genetic factors and ethnic differences, the growth rate of beards is also different. For example: many foreign men usually have longer beards.

What is the relationship between beard growth and longevity?

The study found that people who didn't shave every day had a lower fatality rate than those who shave every day, accounting for about 31 percent of total casualties. People who do not have the habit of shaving have a fatality rate of up to 45%. Therefore, it is known that people who do not shave every day have a higher risk of death.

In this regard, a British university conducted a related experiment, taking 2,438 middle-aged men in England and Wales as a sample and using the method of follow-up survey. The results found that middle-aged men who did not shave every day had a higher prevalence , and this group had a mortality rate that was about 14% higher than that of middle-aged men who shave every day.

However, some studies have found that people who do not have the habit of shaving every day are mostly unmarried blue-collar workers. These groups have poor physical fitness, short stature and are prone to angina. Therefore, whether there is a direct or indirect correlation between shaving habits and longevity has not yet been fully confirmed.
