Sweat itself is colorless and tasteless, and its components can be divided into inorganic components and organic components, both of which are metabolites in the body. Inorganic components are mainly salts such as sodium chloride and calcium carbonate, some of which are acidic and some are alkaline. Excessive accumulation of these acid and alkali components will directly corrode the skin, destroy the tissues and cells of the skin, and lead to skin aging. The accumulation of organic components in sweat on the body surface, driven by high temperature weather, is more conducive to the proliferation of microorganisms on the body surface, which is also the reason why sweat smells after sweating a lot.
Methods to prevent sweaty smell: you can apply a small amount of urotropine solution to the place where sweating is serious, which has the effect of treating hyperhidrosis, but don't use too much. In addition, taking a bath every day can also relieve sweating. Sweating belongs to the natural circulation of the human body, and it cannot be excessively targeted at sweating. Sweating is also harmful to the body.

Sweating itself can also be used as a sign of many diseases, such as:
All kinds of "sweat" can be used as one of the diagnostic basis for spying on diseases.
Cold sweat: whenever people are sick, frightened, or particularly nervous, and their physical and psychological functions are out of order, they will constantly discharge a lot of sweat, making people feel cold. After sweating, I often feel "lingering fear".
Sticky sweat: Sweat is sticky and fever, which is a kind of sick sweat after taking antipyretic drugs. If damp heat stays inside, when it bothers the skin, sticky sweat will appear.
Yellow sweat: Sweat turns yellow and looks like yellow paper, which is mostly caused by cold water bathing after sweating, the evil of cold and dampness entering, or the stagnation of cold and dampness in the texture, resulting in abnormal sweat excretion and increased urea content in sweat.
Sweating profusely: also known as red sweat and muscle bleeding. Sweat is reddish, like meat washing water. Chinese medicine believes that every time qi, blood, yin and yang are on the high side or on the low side, liver fire is vigorous, and yang failure cannot consolidate the exterior, sweat turns red. Modern medicine believes that it is related to endocrine disorders.
Nose sweat: Every time I sweat when I am emotional, nervous, tired from work and talk a lot, sweat seeps from both sides of my nose and drips down slowly, making the sweat crystal clear. It is more common in people with weak lung qi deficiency.
Sweating on the forehead: Sweating is limited to the forehead, even if sweating seems steaming, so it is commonly known as "steamer head". Traditional Chinese medicine believes that the head is a "meeting of all yang" and a "house of wisdom". All exogenous six evils, stagnation of spleen and stomach and injury of viscera can cause sweating on the head and forehead.
Half head sweating: the whole head is divided into two parts by the nose, half head sweating and the other half not sweating. This is because the husband and wife share the same room after a serious illness, and both yin and yang are deficient, which leads to cold blocking the meridians.
Half body sweating: refers to half body sweating, while the other half body does not sweat or sweats very much. Most of them are caused by qi and blood deficiency blocking meridians, which are common in young hypertensive encephalopathy, renal hypertension, stroke, hemiplegia, paraplegia and so on.
Overworked sweat: refers to excessive sweating in the middle part of the heart socket and breast, but no or less sweating in other parts, mostly due to excessive anxiety, thinking, shock and fear, resulting in heart failing to control blood, spleen failing to control blood, and chest sweating. Common in overworked intellectuals.
Hyperhidrosis of hands and feet: Chinese medicine believes that "spleen governs hands and feet", and dampness-heat of spleen and stomach, internal steaming, blood deficiency, yang deficiency and yang deficiency can all lead to hyperhidrosis of hands and feet. Seriously, whether it's cold or hot, my hands and feet are sweaty.
Perspiration in perineum: Perspiration is limited to perineum and external genitalia, and anyone who bets on damp-heat and kidney-yang deficiency can cause sweating, gloomy and smelly. If young women suffer from gynecological diseases such as pruritus vulvae and vaginitis, abnormal perineal sweat may also occur.
Sweating under the armpit: Sweat smells like fox, and it is more intense when sweating in summer, which is caused by abnormal secretion of sweat glands distributed in armpits, legs and armpits. More common in young people, women are more than men, especially adolescent girls.
Sweat with burnt smell: full of relish, continuous, emitting burnt smell or burning coal smell. In severe cases, the burnt smell is very strong, which can stimulate people around to sneeze and shed tears. This disease is limited to young men, masturbating too often, or wet dream's nocturnal emission, and not paying attention to cleaning perineum. In addition, "war sweating" of patients with high fever, "sweating" after surgery or female childbirth, "sweating" at the end of life, spontaneous sweating and night sweats are all different pathological changes or abnormal sweating.
