Athlete's foot is a disease caused by fungal infections, which is highly contagious and recurrent. Most people may carry it for life after being infected, and it is not easy to completely eradicate. Once diagnosed, it is recommended to seek formal treatment at the dermatology department of a regular hospital. During the treatment period, alcohol and spicy food like chili peppers should be avoided, as fungi are particularly sensitive to alcohol and chili, which can stimulate their rapid and increased growth. Common antifungal creams can be applied twice a day, and by persisting for one to two months, the infection can usually be completely cured. After recovery, try to avoid wearing slippers carelessly, and avoid going to public baths or swimming to prevent the fungus from recurring. Adopting good dietary and lifestyle habits can also help suppress outbreaks of this disease.
