This is mainly due to the continuous rainfall over the past two days and the sultry weather, which provides a good living environment for fungus to flourish. Plus people wear sandals after soaking in the rain without timely cleaning and drying their feet, resulting in the growth of ringworm fungus and contracting foot fungus. Patients who develop rotten feet are more often seen wearing poorly ventilated shoes such as travel shoes. In addition, with the popularity of showers, many people just rinse their feet but do not clean their toe crevices, not realizing that the crevices are prone to sweating and are ideal habitats for fungus. Special emphasis must be placed on timely treatment of tinea pedis, and it is crucial to use reasonable and standardized medication to eradicate it. Some patients use medication when foot fungus strikes and stop using it once it is alleviated, which leads to reinfection, prevents eradication, and makes treatment more difficult. In addition, in addition to keeping foot hygiene, people who have a high incidence of foot fungus should lead a regular life, avoid sweat-prone foods such as chili peppers, raw onions, and raw garlic in their diet, and strengthen their physical exercise at ordinary times to enhance their immune system.
