Many people mistakenly think that sweating will produce bad smell, but there is no direct relationship between the two. In fact, sweating is good for the body, because the waste and water in the body can be excreted with sweat, thus promoting metabolism and regulating body temperature.

Sweat glands secreted by human body can be roughly divided into eccrine glands and apocrine glands: eccrine glands are distributed all over the body, and the discharged water only contains a small amount of salt and urea lactate; Apocrine glands are sweat glands attached to hair, which are distributed in armpits, areola and genitals. Sweat secreted is not only rich, but also contains protein, lipids, fatty acids, cholesterol and glucose. 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 odor, but it will produce odor when mixed with bacteria on the skin surface. Some parts of the body, such as armpits, feet, abdomen, etc., are easy to accumulate bacteria and have more sweat glands, so sweat is difficult to evaporate and has a strong smell.

Sweat comes from liver heat.

From the perspective of traditional Chinese medicine, odor is mostly related to the liver. The liver is responsible for processing and decomposing toxic substances, such as fried food, tobacco and alcohol in daily diet, accumulating a large number of toxic substances in the body, increasing the burden on the liver and causing liver fever. Sweating is a way to detoxify, so the sweat of people with liver fire has a smell. Moreover, people with liver fire have higher body temperature than ordinary people, and sweat is more likely, and sweat is mostly red and yellow.
