In the hot summer, after walking home from outside or exercising, sweating and sticky, I wish I could take a shower to refresh. But many of you may have heard the saying:Don’t take a bath right away when you sweat, or you will get sick easily. The most widely circulated saying is: pores expand when sweating, temperature drops when bathing, pores shrink, viruses and bacteria invade, which can easily lead to colds and illnesses, so you should rest and stop sweating before washing. is this real? The skin is the main radiating organ of the human body, and there are indeed glandular openings on the skin, such as the openings of the sweat glands, the openings of the hair follicles and the sebaceous glands. The sweat glands are involved in heat dissipation. After heat generation in a high temperature environment or exercise, under the control of the body temperature center, the sweat glands secrete vigorously. When the weather is hot or after exercising, the capillaries of the skin will expand, which can increase the blood flow of the skin and help to dissipate heat, which is why some people blush when they exercise vigorously. The “pore” that everyone is talking about generally refers to the openings of the hair follicles and sebaceous glands. In a high temperature environment, the secretion of sebaceous glands will also increase, but I have not found the exact reason for the expansion of pores. statement. Even if the pores expand when the heat is dissipated, and when the pores shrink, viruses and bacteria are easy to enter. Compared with the shrinkage when the pores are washed with clean water, compared with the shrinkage when the body is covered in sweat, there must be fewer pathogens entering the former. After all Clear water is cleaner than sweat and body grime that has been left on the skin for a long time. Besides, the skin has a complete barrier function, and there are also epithelial cells inside the hair follicles and sweat glands. Even if viruses and bacteria really enter through the openings of the hair follicles, sebaceous glands and sweat glands, it may not cause infection. Inflammation and prickly heat, at most skin and soft tissue infections, there is no evidence that sweating and bathing will increase the risk of skin infection. Instead, sweating and not bathing are more likely to develop prickly heat. The cold is a respiratory virus infection, and skin infection is a misunderstanding. Another way of saying that, when you take a shower when you sweat, it is not viruses and bacteria that get in, but ”cold”, not to mention that the cold is A substance that does not exist, even if there is such a thing, it should be a swimmer who should be more worried. While sweating vigorously while soaking in water, how much cold air will invade? Swimmers are no more likely to get sick than you. Moreover, you don’t have to take cold water to take a shower. Even in summer, not many people take cold showers. There is also a saying that the sudden constriction of the capillaries in the shower when sweating will cause blood to return and increase the burden on the heart, which may easily lead to sudden death. But the burden on the heart caused by capillary constriction cannot be compared with the burden on the heart during strenuous exercise such as running and playing basketball. If you don’t believe me, feel the heartbeat during bathing and exercise to see which one is faster. And if you say sweat, you can’t take a bath, and you can’t run or climb stairs. Therefore, there is no medical basis for saying that you can’t take a bath immediately if you sweat. I don’t pay much attention to taking a bath. I feel uncomfortable when I sweat. I want to wash it and wash it with whatever water temperature is comfortable. (This article was first published in 2017, with slight changes)
