Is sweat alkaline or acidic

Sweat can be divided into two types on our body, but both are metabolites in the body. However, the smell produced by each type of sweat secretion is different. We will find that some people's sweat will be particularly sour and smelly, but some people's sweat will have a fragrant feeling or no smell. In fact, sweat accumulates in the air for a long time and will have a sour and smelly smell. As for whether the sweat pathway is alkaline or acidic, this question still needs to be understood.

Some are acidic, some are alkaline

Sweat components can be divided into two categories: inorganic components and organic components, both of which are metabolic products in the body. The 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 acidic and alkaline components will directly corrode the skin, destroy the skin's tissue cells, and cause skin aging. The accumulation of organic components in sweat on the body surface, driven by high temperatures, will facilitate the massive reproduction of microorganisms on the body surface.

What's in a cup of sweat? 98-99% of the composition is mainly water, with a specific gravity of approximately 1.002-1.003 and a pH value of 4.2-7.5. NaCl is about 300 mg/100 ml. 1-2% is a small amount of urea, lactic acid, fatty acid, etc.

Sweat is the liquid secreted by sweat glands. Sweating caused by heat stimulation due to increased external temperature or increased heat production in the body is called perceived sweating. At this time, the sweating area is widely distributed, covering the skin of all parts of the body, especially the forehead, neck, front and back of the trunk, waist, back of the hands and forearms; followed by the neck, sides of the trunk and most of the limbs; then the inner side of the thigh and armpits; the least is the palms and feet. Mental stress can also cause sweating. The sweating centers are distributed in various parts of the central nervous system. A normal person evaporates about 600 to 700 ml of water unconsciously within 24 hours.
