Most white people have body odor, because their genes cause the apocrine glands to secrete sweat, which is decomposed by bacteria to produce a taste. Moreover, it is no exaggeration to say that body odor, as a special body odor, is really unpleasant.

The data shows that only 6% of China people have body odor, while 9% of whites and only .5% of blacks have no body odor. Therefore, almost all foreigners have body odor. Among them, a large part is hereditary. It's really embarrassing and annoying to have body odor. However, human body odor existed a long time ago.

It turns out that a long time ago, when human ancestors entered Asia, due to various reasons, their genes were mutated, and the secretion of sweat glands that determined body odor decreased. Over time, most people in China did not have body odor. White people who don't have this genetic mutation are not so lucky. They almost always carry body odor. Body odor is really smelly, which is the smell of sweat accumulation and bacteria decomposition. Sweat secreted by human eccrine glands is almost tasteless because most of it is water. However, the sweat discharged from apocrine glands is closely related to body odor, and its secretion originally has no taste. When the secretion is decomposed by bacteria on the body surface to form unsaturated fatty acids, it has a taste. This smell is distributed under the armpit to form body odor, and some are under the crotch? That is to say, the cause of body odor is the result of sweating and bacteria.

At the same time, the secretion of apocrine glands is also affected by hormones in the body. Diet and mood can affect hormones and body odor. Foreigners will choose perfume to cover up the smell. There is alcohol in perfume, which can sterilize, and the fragrance can cover up the body odor. Some people will choose surgery to remove the apocrine gland under the armpit, which is also a good method. With the development of medicine, many people will choose surgery to get rid of this smell. Many people feel embarrassed because they have body odor, so they have no confidence. After all, the body odor of body odor will not only affect their own lives, but also affect others.
