Sweaty feet, foot odor, caused by the occurrence of many reasons, can be broadly divided into two categories: one is caused by the accumulation of sweat secretion, and another is caused by foot odor. If it is the accumulation of sweat secretion, most of them are related to the developed sweat gland secretion in the feet and genetic factors. In addition, there are poor foot cleaning and hygiene habits, as well as uncomfortable shoes and socks, and an allergic and confined environment, which may lead to the accumulation of sweat, thus making the symptoms of foot odor worse. This condition usually does not require treatment, as long as attention is paid to adequate cleanliness, good hygiene habits, as well as attention to rest and supplementation with fresh vegetables and fruits, etc. In addition, some are caused by foot infections, which are related to fungal infections and must be treated with antifungal treatment in order to eliminate the symptoms more effectively.
