Many people think that sweating will stink, but it has nothing to do with it. Sweat is a dilute liquid secreted by sweat glands, of which water accounts for 99%, and the rest is sodium chloride, potassium, sulfur and urea. Sweat itself has no smell, and only when sweat is mixed with bacteria on the skin surface will it produce smell. Some parts of the body, such as armpits, feet, thighs, etc. Bacteria are easy to accumulate, sweat glands are more, and sweat is more difficult to evaporate, so the smell is stronger. Since bacteria are everywhere and sweating is a normal phenomenon, why do some people have no smell even if they sweat profusely, and why do some people stink when they sweat?

From the perspective of Chinese medicine, this is related to people's physique. In addition to underarm odor, Chinese medicine believes that people with liver heat have a slightly higher body temperature and are prone to sweating, which is red and yellow. According to the viewpoint of modern medicine, the liver is the defense line of the digestive tract, which is responsible for processing and decomposing toxic substances and belongs to the filtering organ. If we don't eat properly, such as eating too much hot and refined food, or smoking and drinking, a lot of toxic substances will accumulate in our bodies and increase the burden on our liver. In addition to defecation, the way to detoxify is through skin pores. Therefore, people with liver disease have a bad smell of sweat. At the same time, the clothes they wear, especially underwear, will have yellow sweat spots and urine will be red and yellow. People with severe liver disease will even turn brown when urinating, and their underwear will be stained with brown.

The first step is to adhere to good hygiene habits. For example, wash your hair and bathe frequently, change your close-fitting clothes in time, and choose shampoo and shower gel suitable for your hair and skin. Using them can effectively control the secretion of oil and fundamentally solve the problem of body odor and unsightly appearance.

Second, insist on detoxification. As I said just now, there are as many as 900 kinds of waste produced by human metabolism, and nearly 300 kinds are discharged from the skin alone. These excrements not only affect masculinity, but also cast a shadow on health, so they should be cleaned up regularly. Specifically, we can start from three aspects: First, we should eat more foods with detoxification function, such as various vegetables (with anti-pollution weapons-alkaline components, which make the blood weakly alkaline, so that toxins deposited in cells can be dissolved again and excreted with urine), kelp (rich in kelp gum, which promotes the discharge of radioactive substances in the body), mung beans (which can help discharge various harmful substances such as heavy metals) and mushrooms (known as blood cleaners). The decomposition of gastric acid and digestive enzymes produces a substance with detoxification and intestine moistening effects), papaya (containing special enzymes, which can not only resist pollution but also lose weight), apple (a prominent anti-pollution fruit), tea (containing anti-radiation components) and so on; The second is active cough. Choose a place with fresh air every morning, cough after inhaling deeply, and discharge the pollutants accumulated in the lungs in the form of sputum to keep breathing and breath fresh; The third is to drink more water, increase urine output, let metabolites be discharged from urinary tract, reduce discharge from skin, and prevent odor from masking normal body odor.

Third, adjust the diet and eat body fragrance. Although body odor is determined by their own genes, if the diet composition is changed, it can be transformed through human metabolism, especially skin cells. For example, iron-containing foods, such as spinach, beans, animal livers, and blood of livestock and poultry, combine with hydrochloric acid in the stomach and become ferrous chloride, which can produce a spring chrysanthemum fragrance similar to hydrogen. Foods containing magnesium, such as wheat, seaweed and beans, can make your body emit apricot fragrance. Stay happy. Emotion is also an important factor in determining body odor. There is a simple reason. When you are nervous and embarrassed, the apocrine glands around the nose, armpits, groin and genitals and the eccrine glands of the whole body secrete actively, the decomposition of staphylococcus accelerates, and the production of short-chain fatty acids increases, which is the main producer of sweat smell. However, when people are calm, stable and happy, the production of short-chain fatty acids decreases and the secretion of "perfume" such as butyrate increases. Even if people usually smell of sweat, the odor can be greatly reduced.
