How to treat heat rash caused by excessive heat

When heat rash is caused by excessive heat, promptly lower the body temperature and keep the skin cool and dry. Wear loose, breathable clothing to facilitate sweat evaporation. Maintain good ventilation in the environment, and use air conditioning or fans to regulate indoor temperature. Keep the skin clean by using mild, non-irritating bathing products, and gently wash the affected area without excessive rubbing. An appropriate amount of talcum powder or a cooling, anti-itch lotion may be applied to relieve symptoms, but avoid using these products on broken skin. Regarding diet, consume foods rich in water and vitamins to promote bodily metabolism. If the heat rash is severe or shows signs of infection, seek medical attention promptly and follow the doctor's instructions for treatment.
