Why do men grow beards? What is the function of beard?

Beard has always been one of the unique symbols of men. Humans have been evolving for thousands of years, but beards are still like that. Walking in the street, you can see all kinds of men, and their beards are all kinds.

Like facial hair, a beard can completely change a person's appearance. Next, why grow a beard?

1, beards show men's health.

A thick beard can often protect the skin on the chin from the outside world, but it also becomes a hotbed of bacteria. Studies have shown that men grow beards just to prove to everyone that I am healthy and will not breed bacteria at all.

In addition, although they are all hair, you should know that the growth rate of beard is much faster than that of hair, with an average of about 0.4 mm per day (hair grows about 0.27-0.4 mm per day). Apart from the fact that the beard absorbs more nutrients than the hair, another reason why the beard grows fast is the role of androgen, which is produced in the testis. So the growth rate of beard also implies the strength of your sexual ability.

The beard protects the face from direct ultraviolet radiation.

Any hair can block ultraviolet rays from directly irradiating the skin-beard is no exception. Walking in the hot sun, a thick beard can definitely keep your chin cool. In this regard, dermatologists Valerie Randall and Ebling suggested that the growth rate of body hair would change with the seasons. The growth rate of male beard in summer is 50% to 60% faster than that in winter.

Men with beards have higher social status.

Tagore, Voltaire, Stalin ... these famous people in history have more or less striking beards. Experiments show that judging from appearance, it is generally believed that men with beards have higher social status than men without beards. Because men with thick beards look more respected and respected than others in society. A survey on the academic level of men in British universities found that the beards of full professors are much thicker than those of lower-level lecturers and researchers.

Looking back at the uncles who fascinate everyone in the entertainment circle, they all have an iconic dress-beard. Indeed, in people's established impression, growing a beard will look older and more mature. Others grow beards to hide their age. Men with beards will also appear more mature and attractive when they get along with women.

4. grow a beard to avoid chin injury

No matter what the effect is, having a thick beard will definitely protect your chin. Imagine that the pain must be different when you fall on the ground naked and when you fall on the ground in a cotton-padded coat. When you accidentally slip and happen to hit the ground with your face first, a thick beard will play a certain buffering role. In cold areas, people grow beards so as not to freeze their chins when the cold wind strikes. In short, growing a beard is definitely the best way to protect your chin.

I believe that most men have had this experience: a pair of hands are coding words quickly in front of the computer, and suddenly they feel an itch in their arms. You habitually put your chin together, scrape your arms left and right, and continue to code quickly ... The stubble on your chin is like a small brush, which can help you when you need it. Of course, if the beard is as long as the hair, forget it. Scratching with a beard will only backfire.

6. Beards can store food.

This is the gospel of cannibalism. As the picture shows, you have a long, thick beard with hamburgers, French fries and even coke hanging on it. Move your mouth if you want to eat. You don't need to pick it up and put it in your mouth at all. You can try it and see how many kinds of food can fit in your beard. Of course, it's best to prepare a handkerchief to prevent juice from splashing on your beard.

Finally, in fact, when it comes to the function of beard, you may think of a cat's beard. Cats' beards are long and straight, which can help them measure the width of the hole to determine whether they can get in.
