What should be noted during the treatment of tinea manuum and tinea pedis (hand and foot fungus)?

Precautions for the treatment of tinea manuum/pedis (hand/foot fungus): 1. **Proper medication use**: Select appropriate antifungal medications and use them according to the prescribed course under a doctor's guidance. Avoid changing the dosage or method of administration arbitrarily to prevent compromising treatment effectiveness. 2. **Keep feet and hands dry**: Maintain dryness of the hands and feet, and avoid prolonged exposure to moist environments, as this can help prevent and alleviate symptoms. 3. **Personal hygiene**: Wash hands frequently, wear breathable shoes and socks, and maintain cleanliness of the hands and feet. Avoid sharing shoes, socks, bathtubs, or other personal items with others to prevent cross-infection. 4. **Diet and rest**: Maintain a light diet and avoid spicy or irritating foods. Engage in moderate exercise and ensure adequate rest to enhance the body's immunity. 5. **Avoid irritation**: During treatment, protect the skin from irritants that may cause damage, such as highly concentrated hand sanitizers or chemical additives.
