What Causes Onychomycosis?

Heavy Sweating

Heavy sweating increases an individual's risk of developing a fungal infection, since fungus thrives and grows best in moist areas. This is part of why toenails are more likely to develop an infection than fingernails. When individuals wear wet shoes or sweat excessively, their feet stay moist and damp throughout the day. Walking through puddles and rainy conditions can also exacerbate this. Wearing socks can sometimes help protect the feet from outside elements, but sweat can collect inside the sock and make the foot damp regardless. If individuals sweat heavily enough that it's a consistent problem, they might want to ask a doctor to check for underlying medical conditions. For individuals who engage in activities that cause excessive sweating, including manual labor and heavy exercise, one of the best things they can do is get proper footwear. There are several running shoes and athletic shoes designed with mesh that removes moisture from the feet to keep them dry. Not only does this help individuals keep their grip as they walk, but it also lowers their risk of infection.
