1, dirt produced by the body
Through normal metabolism, the body will discharge a certain amount of oil, and when it meets the dust in the air, it will form a certain amount of dirt. In addition, when people exercise, they will accelerate the perspiration of their bodies and become dirt after solidification. These dirty things are the things we usually rub down, which belong to the waste discharged by the body and need to be cleaned up in time. However, there are differences between southerners and northerners. Northerners don't often take a bath, so they have the concept of rubbing. On the other hand, southerners take a bath almost every day, and there is not much dirt on them.
2. horniness on the body
There will also be keratin in the dirt that is wiped off, which is equivalent to the protective film of the skin, but it will be replaced with the metabolism of the body. Under normal circumstances, the stratum corneum will be replaced around 28-30, and it needs to be wiped off by bathing. It is the same whether it is a southerner or a northerner. Although southerners often take a bath, they should also pay attention to the exfoliated keratin, which may affect the skin if not cleaned. For example, symptoms such as allergies and itching are likely to be caused by skin keratin not being cleaned.
3. What should I pay attention to when taking a bath?
Many people will work hard when taking a shower, thinking that they can wash themselves clean. In fact, this idea is wrong. When the body temperature is high enough, the dirt on the epidermis will easily fall off. If you rub too hard at this time, it will only affect the stratum corneum on the skin surface. When the stratum corneum falls off, your skin resistance will decrease, and you may be more susceptible to allergies.
