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.
