It is precisely these two situations that I have encountered, and I can analyze them separately with you.
I used to live with my senior when I was at school. That senior was a wonder. Not only does he dislike taking a bath, but he also dislikes washing clothes. She often takes off her out-of-season clothes, finds a sack, pours washing powder and soap, and then dries it in the sun. No need to wash by hand at all. To put it bluntly, she washes clothes with the heat released by solar energy. At that time, he smelled beyond description. It smells of sour sweat.
Besides, he washes his hair once a week on average. If he takes a bath in the bathhouse, he will have a little close contact with the water, put on soap and come out quickly.
Fortunately, this senior graduated three years earlier than us, otherwise I believe our roommates will be crazy by then.
Of course, there is a special situation, that is, some people's cuticle is so thin that it can be called fragile, so he will pay very careful attention when taking a shower. If someone rubs his back, he will cry with pain.
People with thin cuticle obviously have a characteristic, that is, when taking a bath, the skin will be red and hot when rubbed. If they rub it a few times more, there will be small spots, indicating that the stratum corneum is damaged and scars will appear.
In the sense of modern health care, stratum corneum can protect our skin, especially when taking a bath. If the stratum corneum is deliberately destroyed, there is thin water vapor in the bathhouse, which will enter our body, get wet, and then accumulate in the body, causing skin diseases and joint pain in the future.
So we usually only rub it once a week in the shower, you, because when the dust and keratin on our skin accumulate to a certain extent, we just gently remove one layer from our body and the rest can protect our skin. From this perspective, it is not that he doesn't like cleanliness, but that he protects his body from the perspective of health preservation.
