Tinea pedis is actually a superficial fungal disease that is most common on the skin and is caused by more than 90% of Trichophyton rubrum, followed by Trichophyton rubrum and Flocculina epidermidis, among others. There are more than 600 sweat glands per square centimeter of the human foot, which is two to four times more than other parts of the body, and a total of more than 250,000 sweat glands, which can produce nearly 500 ml of sweat a day. Who is prone to tinea pedis? People like young adults, people who like to play sports, people who like to be active, people who sweat easily, and people who often wear shoes that are not breathable or do not like to take a bath all provide a better environment for the growth of superficial fungal diseases. In addition to this, people with diabetes and those who use hormones or immunosuppressive drugs for a long time are also prone to tinea pedis.
