How to resolve persistent heat rash that does not go away

If prickly heat does not resolve, the following measures may help: 1. **Improve the environment**: Try to avoid staying in hot and humid environments for prolonged periods. Maintain a comfortable indoor temperature and humidity level, ensure regular ventilation, reduce sweating, and promote sweat evaporation. 2. **Topical treatments**: Apply calamine lotion with menthol or prickly heat powder to the affected areas. These products can provide a soothing and cooling effect, helping to alleviate symptoms. If itching is severe, oral antihistamines such as loratadine tablets may be taken under a physician's guidance. 3. **Maintain cleanliness**: Bathe frequently and change clothes regularly. Choose cotton clothing that is breathable and avoid wearing tight-fitting or non-breathable garments to reduce skin friction and sweat accumulation. 4. **Dietary adjustments**: Reduce consumption of spicy or greasy foods to minimize irritation to the skin surface. 5. **Seek medical advice**: If symptoms persist despite the above measures, it is recommended to consult a healthcare professional to rule out other possible skin conditions and receive targeted treatment under medical supervision.
