1: Avoid heat rash by keeping the skin cool and dry. Take special care when you go on holiday to a hot country.

2: Drink plenty of fluids, but avoid hot drinks which raise body temperature.

3: Dress in suitably loose, light, cotton clothing. Don’t put nylon or synthetics next to baby’s skin in hot weather. It is best to sleep in cotton sheets and nightclothes.

4: Prevent young children from becoming too hot by discouraging very active games in hot water.

5: In tropical countries, always carry a jar of dusting powder containing zinc oxide, and apply it to your own skin and children’s skin daily, after bathing.
