We have been taught to be "hygienic and polite" since childhood.
Mother told us that personal clothes should be disinfected, food should be thrown away when it falls on the ground, and dirty things should not be touched casually. .....
However, sometimes "love cleanliness" will become the cause of illness, and even make you incurable for a long time. Can you believe it?
First, too clean is bad for your health? People think that living in a very clean and hygienic environment reduces the chances of contact with microorganisms, but it may affect the normal development of human immune system.
For decades, this hypothesis has been supported by more and more research evidence and is called "health hypothesis".
In fact, our ancestors also said something similar, "unclean things will not get sick if eaten", and there is some truth.
Not only children, but everyone is the same. It is naturally a good thing to talk about hygiene, but there is really no need to be too clean in some places. Excessive pursuit of cleanliness may be harmful to yourself.
Second, these two places are too clean, but not good.
1, skin
For "washing your face", many people are obsessed with it-washing your face "clean".
Wash your face when you oil it, and wash your face when you go out ... I'm afraid it won't be clean, so I have to use all kinds of facial cleanser with matte ingredients, facial cleanser and even facial cleanser.
However, it is this "love of cleanliness" that makes many people's faces "work" into sensitive muscles.
As the first line of defense, skin has an important barrier function. In nature, our skin is weakly acidic, and the normal acidic environment is more suitable for the growth of beneficial bacteria and inhibits the reproduction of harmful bacteria.
2. Ear canal
Ear itching, earwax, with the help of a cotton swab or ear spoon, just clean the ear, I believe everyone has done it.
However, the case report in the medical journal shared a terrible medical record about ear pulling. A healthy boy of 3 1 year-old had a "serious ear infection" because his ear was pulled out with a cotton swab.
It turned out that the young man picked his ear with a cotton swab, resulting in cotton wool residue, cotton wool mixed with bacteria in the ear canal, which brought infection to the central nervous system and eventually caused brain abscess!
In fact, a normal ear canal has a natural protective barrier. Frequent use of cotton swabs and ear spoons may break this barrier, easily lead to the entry of bacteria and viruses, and lead to ear diseases such as otitis media.
Moreover, earwax (earwax) has the functions of waterproof, protecting the skin of ear canal and avoiding ear infection. With the action of chewing and talking, you can clean up the excess earwax in the ear canal, generally without frequent cleaning with instruments.
If there is really a large piece of earwax blocking the ear canal and affecting hearing, you still need to seek the help of a professional doctor.
