My country, Spain, is famous for its beaches. Everyone native leaves the beach in the middle of the day and returns after lunch/siesta, when the rays are less intense.

Tourists are an especially bad example since they often work indoors all year or come from less sunny countries, so the sudden sun exposure is doubly bad for them.
