What should I do if I just stand under the creak nest on the subway?urgent!Wait online!

What kind of taste? I don't matter whether I am not me

Summer, hot air,

Seeing the temperature rising every day, day and earth,

"Go out for 5 minutes, sweat for 2 hours"

Is it your true portrayal?

It doesn't matter if you sweat,

There is a taste to be dead.

On the crowded subway,

The people who entered the station on the left were sweaty,

Raise your hands and throw your feet,

There is a "mysterious taste",

fortunately,

A faint aroma floating on the girl on the right,

Save the poor nose.

But all kinds of odor are mixed together,

Not very good.

then,

I started thinking,

Why are they all appreciate?

Some people smell "fragrant",

Some people are "stinky"?

Sweet sweat or sweaty

How does human taste come from?

Remember the Xiangfei in "Return to Pearl"? She is a person with different fragrances in the play. Qianlong described it for her to "hit her for her crazy for her" for her. Is Xiang Fei really a natural fragrance?

To figure out this point, first of all the smell of the human body comes from?

The smell of the human body is produced in the process of metabolism, which is related to the human body's metabolic output substances. There are two main methods for human skin metabolic channels:

One is the sebum secretion of the skin sebaceous glands, which is usually referred to as the oil on the surface of the skin, and it will form a sebum film on the surface of the skin. For sebum exposure to the air for a long time, it will be oxidized, forming oxidation lipids, and oxidative lipids will emit specific odors.

The other is the sweat secreted by the sweat glands, which is the leading factor that affects the body. More than 98%of the sweat are water, 1%to 2%are urea, lactic acid, fatty acids, etc. These substances will produce different degrees of flavor after the bacteria of the body surface.

Theoretically, if the denseness is suitable, it will become fragrant, and if it is too strong, it will become sweaty, but the latter is often in most cases.

In fact, daily chemical products are the source of aroma for most girls. Girls' daily cosmetics, bath milk, and shampoo generally contain spices. After use, chemicals in the spices will remain on the surface of the body.

Is there a "odor" a body odor?

Because of the smell of the anus of the fox, underarm odor is often called body odor.

Body odor, a big name that makes the big girl, Xiaoxianrou, and handsome uncle. In daily life, it is often a bit of "odor" to be hung on the name of body odor. In fact, it is not all!

There are two members of the "sweat glands" in our body, namely small sweat glands and big sweat glands. The scope of the big sweat glands is relatively limited, only distributed in armpits, outer ear canal, and vulva. The sweat glands are almost distributed throughout the body, accounting for about 90 % of the total sweat glands.

Generally speaking, the sweat from the sweat glands is relatively rare, most of which are moisture, and there is no taste, so it can exclude the suspicion of body odor.

Then, the "murderer" is locked on the sweat glands. But the sweat glands are also calling for injustice. What is going on?

It turns out that except for sweat from the sweat glands, although the water contains various proteins and fatty acids, these things are also tasteless.

But badness is bad. There are still many bacteria on the surface of our skin. The secretions of the big sweat glands just provide growth conditions for bacteria. When they are broken down by bacteria, they will produce small molecular organic matter with strong odor. Generally, they are compared to compare Unpleasant, that is, we said "underarm odor".

Therefore, sweat gland secretions are the basis of underarm odor, and bacteria are the culprits that cause underarm odor.

Is there must be "odor"? It may also be the sweaty smell under the axillary of adolescence. Adolescent sweat smell can be reduced or even disappeared after adolescence. People with this situation can use sweat -controlling and anti -sweats.

How to distinguish? There is a feature that can be distinguished -ears! ("Oil ears", also known as wet ears, that is, the secretions in the ears "earwax" is humid, and the secretions of most East Asian ears are dry.) Generally speaking People with oily ears are likely to have body odor!

It is "normal" with body odor

No body odor is "abnormal"

Understand the reason for body odor, but it has new confusion. It stands to reason that everyone has sweat glands, and everyone has bacteria. So why only a few people have body odor?

In the early ancient times, "body odor" was indeed "dew is stained" to our ancestors, and all people have it. You can imagine the spectacular scenes that they gather together, and the smell can be smelled a few miles away.

At that time, it was normal for body odor. Those who did not have body odor were laughed at by others, but as time passed, the situation gradually changed.

Our ancestors continued to migrate, and some humans walked out of tropical Africa and entered temperate Asia. Here, the "in charge of" the No. 16 chromosomal ABCC11 gene secreted by the "in charge of" the sweat glands has mutated a alkali base on the ABCC11 gene, which reduces the secretions of the sweat glands.

This means that the growth conditions of bacterial growth that can produce odor deteriorate, and the body will become "refreshing." Moreover, this gene mutation mainly occurs in East Asia, because sweating is less, which is more suitable for the cold climate of the temperate zone, but has become a genetic advantage.

After that, this refreshing gene was inherited from generation to generation. At present, 95%of the Chinese are "alien" of gene mutations, and body odor has become a very small number.

Their genes maintain their primitive appearance and have no mutations. Big sweat glands secrete more protein and fatty acids than others. Body odor is not only hereditary, but also related to gender and race. Most white and black people still maintain the "smell" of the old ancestors. There are only 30%of the Oceania indigenous people without body odor, only 10%of white people have no body odor, black people are the most pitiful, only 0.5%without body odor.

The distribution map of the body odor world

In the picture above, Lan has body odor, and Huang is no body odor. Except for East Asia, other places are a sea of ​​body odor.

How to be a "self -aroma" person?

The occurrence of body odor requires the two conditions of body surface bacteria and sweat glands. To change "odor" to "aroma", it is naturally necessary to start from these two points.

Regardless of the method, the core principles are sweat removal + bacteriostatic, reducing the creation of unpleasant smells. In general, there are two categories: one kind of non -surgical therapy, including external drugs, injection therapy, laser physical therapy, etc.; The other is surgical therapy, including traditional surgery and minimally invasive surgery.

Personal daily hygiene habits are also closely related to underarm odor, which helps to stay away from underarm odor.

Develop good personal hygiene habits and take a bath. Bathing with sterilization soap can be completely cleaned at the armpits and groin with odor.

Use some perfume and sweat -proof agent appropriately. Anti -sweats can suppress sweat and antineromy, so that the sweat glands should not produce sufficient unsaturated fatty acids or make bacteria not breed, and can temporarily avoid odor.

Pay attention to avoid "food -oriented food". Such as seafood, onion, garlic, pepper, fennel, and curry, these foods can produce protein and fat decompositions, exudate in the body through pores, so that the body emits an unpleasant smell.

Body odor does not cause harm to our health and sometimes cause some embarrassment. Although there is no way to completely cure body odor, we can choose the appropriate method to make ourselves the "self -aroma" person according to our own situation.
