How to deal with heat rash on the body? Are there any methods?

When experiencing prickly heat (heat rash), the following measures can be taken to alleviate and treat the condition: 1. Keep the affected area clean and dry: Wash the rash area with clean water or normal saline, and keep the skin clean and dry to help relieve symptoms. 2. Adjust the environment: Lower the indoor temperature to around 20°C, avoid hot and humid environments, reduce sweat secretion, and aid in resolving the rash. 3. Use talcum powder or cooling oil: Apply an appropriate amount of talcum powder or cooling oil on the affected area to absorb sweat, keep the skin dry, and relieve itching and discomfort. 4. Cold compress: Apply a cold towel or ice pack to the affected area to lower skin temperature and alleviate itching and prickling sensations. 5. Topical medications: Under a doctor's guidance, use topical medications such as calamine lotion or hydrocortisone butyrate cream, which have anti-itch and anti-inflammatory effects and can aid in resolving the rash. 6. Oral medications: If the symptoms of prickly heat are severe, oral antihistamines or other medications may be taken under a doctor's supervision to relieve itching and discomfort.
