During the treatment or onset of tinea pedis, it is highly advisable to avoid spicy and irritating foods, such as chili peppers, lamb, seafood, as well as smoking and alcohol. These should be avoided as much as possible because the fungus is particularly sensitive to these substances, and consuming them frequently can lead to severe fungal outbreaks and rapid reproduction. Therefore, proper treatment is essential, and maintaining regulated diet and lifestyle habits is crucial to prevent recurrence. You can use common antifungal creams for external application twice a day, persisting for at least one to two months to achieve complete recovery. After recovery, avoid soaking in public baths, swimming, wearing other people's slippers, and ensure your socks and shoes are thoroughly sun-dried and disinfected. Also, avoid sharing towels, footbaths, and other personal items with family members.
