What does it mean that men shave more often? Or what does it have to do with lifespan?

Men have beards and beards on the sides of the cheeks and lips. When boys enter spring and puberty, they start to grow beards. This also shows that men have entered a stage of development and maturity. Some people's beards grow faster and if not cleaned in time, will It affects their personal image, looks sloppy and unclean, so for most men, the first thing to do in the morning is to shave, just like girls do makeup every day.

The growth rate of beard is closely related to the secretion of human androgen. A healthy male's beard grows at a rate of about 0.4 millimeters per day. If the body androgen secretion is more vigorous, the beard grows faster.

Why do men grow beards?

Let's see why men grow beards, regardless of whether there is a relationship between men's life expectancy and beards, people still believe that beards are a product of men's attraction to the opposite sex, surveys and studies have found that in women's preference for men, some people prefer Men, some prefer boys, so the evidence is inconsistent and cannot be judged.

Some people think that men grow beards to reproduce offspring, while men grow beards to increase the chance of mating. Research shows that men with long beards are perceived by many men and women to be more deterrent, and bearded men can scare men in front of their opponents and increase their chances of mating. Other studies have found that people with beards see themselves as having an advantage over others.

Therefore, in the age of survival of the fittest and natural selection in the past, men have long beards in the process of continuous evolution, which greatly represents the charm of men to a certain extent. Therefore, when the beard is messy, it will make people look sloppy and decadent.

What does it mean by how often a man shaves?

Men shave more often when their beards grow faster. There are many reasons for the rapid growth of male beards, among which the strong secretion of androgen accounts for a large part. For male friends, if they want to maintain a normal life, they must have enough androgens to support them.

Exuberant body hair is one of the main manifestations of strong androgen secretion. For people with strong androgen secretion, vigorous body hair is not only reflected in the rapid growth of beards, but also in the vigorous growth of body hair. But many people don't know that people with strong androgen secretion also have some inherent advantages, which will make people envious. The specific advantages are as follows.

Or has something to do with longevity?

One study found that people who shave regularly have a relatively lower number of deaths, at 31% of all deaths, compared to people who don't shave every day, while those who shave infrequently account for 45% of total deaths .

People who don't shave every day have a higher risk of death, or are affected by smoking and other bad habits, and possibly hormones. The study also found that people who didn't shave had a relatively higher risk of stroke, without in-depth research on the factors that affect them.

The study was not rigorous, and other factors, such as lifestyle, age, weight, and the presence of underlying medical conditions, were not considered in the data analysis, which is not very comprehensive.

So it remains to be seen whether the frequency of infrequent shaving is related to longevity. I hope you can treat it rationally and don't blindly believe some words.

Why do some men feel tingling when they shave?

1. The skin is not clean.

If the skin is not cleaned or not cleaned properly before shaving, the dust, oil and blades on the face will come into direct contact with the skin, which can easily cause skin irritation and inflammation.

2. Unclean blades.

Men are advised to wash after using the razor. If you don't wash your beard or hair follicles, there will be a lot of keratin, which can breed a lot of bacteria. If there is a wound when shaving, it is easy to get bacterial infection.

3. Do not scrape along the grain.

Shaving in the specific direction in which the eyebrows grow can cause beard tingling, the same way shaving in the specific direction the hair follicle grows.

Conclusion: Although regular shaving can be boring, it can make a person look fresher and tidier, so it is best for male friends to shave once a day.
