To help protect yourself or your child from heat rash: 1. Avoid overdressing. In summer, wear soft, lightweight, cotton clothing. In winter, children should dress only as warmly as an adult. 2. Avoid tightfitting clothes that can irritate skin. 3. When it's hot, stay in the shade or in an air-conditioned building or use a fan to circulate the air. 4. Keep your sleeping area cool and well-ventilated.
