I've heard that kids with chickenpox shouldn't be exposed to sunlight. Is this true, and if so, why? - Angie
It's wise to avoid the sun during a chickenpox infection and also soon after because the skin is more susceptible to being burned. And sun exposure may increase the risk of scarring.
Heat and sweating (often caused by spending too much time in the sun) will make the pox itch more. If this is a problem, putting cold, wet washcloths on the affected areas should bring your child some relief.
