Preventing heat rash is possible and easy. Here are some precautions you can take. • Avoid going out in hot and humid weather. • Wear light clothes with cool colors. Avoid heavy clothing and dark colors. • Drink moderately cold water and juices. Fresh juices and ORS are important as they replenish the lost electrolytes. • Use fans and air-conditioners. • Avoid eating heavy meals. Keep lunch and dinner simple. • Avoid any strenuous activity and exercises. If you work out regularly, choose a light exercise and work out for few minutes. Drink juice after work out and sit under a fan. Avoid air-conditioners immediately after sweating. • Take bath with cold water.
