What causes foot odor? Here are four reasons to tell you

What causes foot odor? Foot odor is caused by the large number of sweat glands in the soles of the feet, which make them sweat easily. In addition to water and salt, sweat also contains lactic acid and urea. Under conditions of excessive sweating, the bacteria on the feet increase significantly. Let's explore it together.

Because the soles of the feet have more sweat glands than other parts of the body. There are about 620 sweat glands per square centimeter on the soles of the feet, while there are only 143 to 339 sweat glands per square centimeter in other parts of the body. When people become more active, the weather is hot, they are nervous, or they eat spicy or hot food, they will sweat a lot.

Cause

1. Excessive sweating of the feet. It is more common in adolescents, and may be due to unstable autonomic nervous function, such as emotional tension causing excessive excitement of the sympathetic nerves, or exercise, which can cause excessive sweating of the feet.

2. Certain diseases of the feet, such as skin diseases such as tinea pedis between the toes.

3. Often wear rubber shoes, nylon socks and other shoes and socks with poor breathability.

4. Or some people do not pay attention to the cleanliness of their feet. The temperature of the foot skin and sweat form humidity and dandruff, which constitute suitable conditions for the growth, reproduction and corruption of microorganisms (especially anaerobic bacteria) on the surface of the foot skin. In addition, the decomposition of organic matter such as uric acid and lactic acid in sweat results in bad odor. If you don't pay attention to the cleanliness of your feet, it will only contribute to the odor.
