　　The main component of 98~99% is water, with a specific gravity between 1.002~1.003 and a pH value of 4.2~7.5. NaCl is approximately 300 milligrams per 100 milliliters. 1-2% is a small amount of urea, lactic acid, fatty acids, etc.

　　Sweat is a fluid secreted by sweat glands. Sweating caused by thermal stimulation caused by an increase in external temperature or internal heat production is called perceptual sweating. At this time, the sweating area is widely distributed, with the skin of various parts of the body, especially the forehead, neck, front and back of the trunk, waist, back of hand, and forearm, being the most common; Next are the neck, sides of the trunk, and most of the limbs; Again, on the inner side of the thigh and under the armpit; At least the palms and feet. Mental tension also causes sweating, with sweat centers distributed in various parts of the central nervous system. Normal people unconsciously evaporate about 600-700 milliliters of water within 24 hours.

　　Sweating can be divided into two types: active and passive. The so-called passive sweating refers to sweating caused by stuffy weather and irritability, which is detrimental to the human body. On the contrary, the sweat produced by the active movement of the human body is called active sweating, which helps to maintain the temperature inside the body, dissipate heat, and is beneficial to people's physical and mental health.

　　The function of sweat is to regulate body temperature. When you think about it, the human body is really like a precision machine. If you don't sweat, it's bad. Exercise accelerates blood circulation, increases body temperature, causes sweating, and lowers body temperature; When it gets cold, sweat glands and pores contract and stop sweating to prevent body temperature loss.

　　Sweat is the "air conditioning" of our body. According to traditional Chinese medicine, sweating occurs in summer, which is a form of detoxification. There are two ways for people to detoxify: urination and sweating. Sweating is the most effective way of detoxification. Only summer can naturally sweat throughout the year, which is beneficial for the body's metabolism, meridian balance, and immune system health. If you keep holding it for a long time without sweating, the skin will no longer be able to breathe, ultimately causing many metabolic disorders in the human body, and transferring the detoxification function of this skin to the kidneys and liver.
