Why do some people shave off the hair below?

Humans are always curious about their bodies. When they are bored, they always pinch here, rub there, turn their fingers and draw circles in some parts of their hair to relieve the loneliness of their hands.

We may be just curious, but boring Americans spent three years doing a national survey on pubic hair, and the result was unexpected: most women shaved their pubic hair for personal hygiene reasons.

This paper published in JAMA Dermatology shows that pubic hair trimming is becoming a female trend. 84% of women have trimmed their pubic hair, 62% have shaved it thoroughly at least once, and up to 59% of women think it is unhealthy to grow Mao Mao underneath.

In this regard, gynecologists said: completely incomprehensible!

Obviously, Americans are not the only ones who are interested in Mao Mao. Maybe summer makes people feel hot and fidgety. Recently, there have been more private messages in the background:

"Well, Mao Mao below me is very itchy. Can you shave it off? "

"unfair! Why is my best friend naked, but I am' overgrown with weeds'! It's a shame to sneak out every time I wear swimming trunks! "

"When I took a shower, I found that some hairs turned white below. What's the matter? "

Why are some people naked, while others are flourishing? Did it work? Can I shave it off for beauty? These problems will be solved today.

First, what is the "bottom" hair? Why don't some people?

Man is a magical species. We have tried our best to evolve, but some places are still in the past, such as private hair.

Compared with other primates, this part of human hair is thicker and denser, which impressed the ape. According to research, at some time 3.3 million years ago, human beings evolved pubic hair thick enough, when most parts of the body surface had no hair. These thick hairs are concentrated in the apocrine sweat glands and exocrine sweat glands, which helps to spread the hormonal odor of sexual maturity signals to the outside, thus attracting the opposite sex.
