When is it NOT necessary for a person to wear sunscreen during a recreational activity?

Sunscreen protects skin from ultraviolet (UV) rays, which can reach people outdoors even when it is cold, cloudy, or partly shaded. During an activity that takes place indoors, a person generally does not need sunscreen unless they are near a sunny window or otherwise exposed to UV rays. So the best choice is “when the activity is indoors.”
