How to deal with itchy prickly heat rash on the body

When experiencing prickly heat (heat rash) accompanied by itching, the following measures can be taken to alleviate symptoms: 1. **Maintain cleanliness and dryness**: Bathe frequently, choose gentle cleansers suitable for sensitive skin, and keep the skin clean and dry to prevent sweat from remaining on the skin surface for prolonged periods. 2. **Physical therapy**: Apply cold compresses or soak the affected area in lukewarm water to relieve itching. Wrap ice cubes in a towel and gently place them on the rash to reduce local skin temperature and effectively ease the itching sensation. 3. **Topical medications**: Under a doctor's guidance, apply calamine lotion, prickly heat powder, or other medications with anti-itch and anti-inflammatory effects to help relieve symptoms of heat rash. 4. **Avoid irritation**: Wear loose, breathable clothing, avoid using irritating bathing products, and minimize skin friction and pressure to prevent worsening of symptoms. 5. **Oral medications**: If itching is severe, take oral antihistamines such as loratadine or cetirizine as directed by a physician to help alleviate the itching.
