What is the cause of foot odor? In fact, there are many reasons that lead to foot odor. Let's take a look at them in this article.

Whatever the problem is, there is a reason. The same is true for the appearance of foot odor. Understanding the causes of foot odor can not only help everyone effectively prevent the occurrence of foot odor, but also help people with foot odor to "prescribe the right medicine" to relieve the trouble of foot odor. Our feet have relatively abundant sweat glands, with about 620 sweat glands per square centimeter in the soles of the feet, while other parts of the body have only 143 to 339 sweat glands per square centimeter in the same area. When people become more active, the weather is hot, they are nervous, or they eat spicy or hot food, they will sweat a lot. After sweating, the humidity and pH value inside the shoes provide a suitable growth environment for bacteria. In addition, the necrotic stratum corneum of the skin provides sufficient nutrition for the bacteria, allowing them to multiply in large numbers, decomposing keratin and mixing with urea and lactic acid in sweat to produce an unpleasant odor.

Causes of foot odor

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. Shoes and socks have poor air permeability, such as rubber shoes, nylon socks, leather shoes and other shoes and socks with poor air permeability.

4. Excessive sweating on the feet and poor evaporation of sweat cause the epidermis to become white-soaked, especially between the toes. Severe excessive sweating can cause blisters, erosion or excessive keratinization, which can easily lead to fungal infection and cause foot odor.

5. Damage: When the skin is damaged, it will affect the skin's defense function, making it easier for pathogenic fungi to invade and settle, causing foot odor.

6. Obesity: Obese people are more likely to sweat, and the moisture and soaking between the toes induce foot odor.

7. 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.

After reading the introduction in this article, everyone should have some understanding of the causes of foot odor. Now that the weather is getting hotter, many people have more serious problems with sweaty feet. To avoid foot odor at this time, you should pay attention to washing socks and changing shoes frequently. If you have any foot diseases, you should seek timely treatment to avoid foot infection.
