How often a man shaves, determines the length of life? Health experts: It is best not to shave for two times

For boys, there are some noticeable changes in the body during puberty, such as throat bulges, beard growth, and more. Today, let's focus on beards. As for beards, some boys keep them long on purpose to show their true colors, while others choose to have them cleaned regularly to appear cleaner. Recently, there has been a saying on the Internet that the frequency of men shaving is related to their life expectancy. Is it really?

How often a man shaves, determines his lifespan?

Such a simple and rough summary is very unreliable. Because we all know that there are many factors that determine lifespan, such as genetics, environment, personal constitution, living habits, diseases, accidents and so on. So, where does the relationship between shaving frequency and longevity come from?

There is such an explanation on the Internet: Men's beards grow fast, which indicates that their endocrine is very good, especially the secretion of androgen is very strong. It's very masculine! Therefore, people with high androgen production need to shave more frequently. Correspondingly, those with less androgen production tended to have slower beard growth and therefore less frequent shaving. This sounds reasonable, but what about men without beards? After all, beards also have a genetic component.

Also, even boys with beards grow at different rates at different ages. For example, during adolescence, beards may grow rapidly. In adulthood, even in middle-aged and elderly people, the growth rate will be slower and slower, which has nothing to do with life.

Therefore, it is unreliable to say that the frequency of shaving determines the length of lifespan!

Shave, two no.

It is best not to shave before the age of 20: I believe that many boys are looking forward to growing a beard after entering puberty, so that they can look better "man" and more mature, and you can use a razor reasonably. In fact, it's best not to shave during this time. Strictly speaking, the beard at this time is not a beard, but a black fluff. At this point, it is easy to scratch the skin. Over time, it is easy to make nearby skin rougher,

Don't shave before strenuous exercise: Because if you go to the sports field after wearing a beard, blood circulation will increase after exercise. In addition, the large amount of sweat produced during exercise can irritate the skin that has just been shaved, which can easily lead to infection.

The best time to shave: Half an hour after getting up in the morning, because after a night of sleep, the body's sebaceous glands secrete vigorously and hair grows vigorously. After waking up in the morning, the skin is relatively relaxed and ideal for shaving.

Body cold knowledge: Beards are easy to go bald

In society, in addition to the frequency of shaving, it shows its androgen secretion, and even affects the length of its lifespan. There is also a saying, probably not many people have heard of it: people with beards are prone to baldness!

There's another way of saying "research" to this claim compared to lifespan: a survey found that the longer the beard and the longer you've had it, the more likely you are to go bald! Because having a beard produces more heat, the body reduces the amount of heat that the hair releases to maintain an optimal heat balance. Maybe it's a little hard to understand. It can be simply understood as: the hair (beard) that grows on the mouth will eat nutrition, leaving less nutrition for the scalp. Over time, the hair will disappear…
