What causes sour smell in sweat

Sweating is a normal physiological phenomenon of the human body, especially after doing heavy physical work, or in the hot summer, or after exercising, people often sweat profusely. Some people find that their sweat has a sour smell. If the smell is not strong, there is no need to worry too much, because getting a sour smell can easily lead to dampness and heat in the body, and at this time the sweat will often be sour and smelly. In addition, diseases such as hyperthyroidism and adrenal tumors can also cause sweat to have a sour odor.

1. What causes sour and smelly sweat?

1. Sweat itself has no odor, but when sweat mixes with bacteria on the surface of the skin, it produces a bad odor. Certain parts of the body, such as the armpits, feet and groin, are prone to bacteria accumulation and have more sweat glands, so sweat is more difficult to evaporate and has a stronger odor.

2. In addition to high temperature, pressure, and emotional tension that make people sweat, we also need to be aware that diseases such as hyperthyroidism and adrenal tumors can also increase sweating.

3. It may be that you have eaten too much meat recently, and the urea content in your sweat is higher, making it smelly.

4. From the perspective of traditional Chinese medicine, smelly sweat comes from liver heat, and the bad smell is mostly related to the liver.

5. Consider the phenomenon of damp heat caused by eating spicy food, drinking too much alcohol, or being angry and irritated frequently. The damp heat fumigates the skin and causes frequent sweating, which becomes sticky and has a sour and smelly smell. In daily life, you should pay attention to eating less spicy food, drinking less alcohol, getting angry less and getting less irritated. If you are fat, you should pay attention to losing weight. If you are fat, you should avoid eating greasy, high-cholesterol, and high-fat foods. Check your blood lipids, blood sugar, blood pressure, etc. regularly.

2. What is physiological sweat odor?

The physiological reasons are related to the location of sweating. Sweat is a thin fluid secreted by sweat glands, of which water accounts for 99%, and the rest is sodium chloride, potassium, sulfur and urea. The sweat glands that secrete sweat in the human body can be roughly divided into two types: eccrine sweat glands and apocrine sweat glands. The eccrine sweat glands are distributed throughout the body, and the water they secrete contains only a small amount of salt, lactic acid, urea, etc.; while the apocrine sweat glands are sweat glands attached to the hair, and are distributed in the armpits, areola, and pubic area. The sweat they secrete is not only rich, but also contains a variety of components such as protein, lipids, fatty acids, cholesterol, and glucose.

3. Why do people with liver heat sweat sour and smelly? From the perspective of traditional Chinese medicine, the bad smell is mostly related to the liver. The liver is responsible for processing and breaking down toxic substances. Fried foods, tobacco and alcohol in our daily diet cause a lot of toxic substances to accumulate in the body, increasing the burden on the liver and causing liver heat. Sweating is a way to detoxify, so the sweat of people with liver heat often has an unpleasant odor. 4. Benefits of Sweating

Sweating is good for your health because waste and water in the body can be excreted through sweat, thereby promoting metabolism and regulating body temperature.
