#48: How Strong the Sun Can Be
Sunscreen advice in America can sound dramatic until someone spends a day outdoors and realizes it is serious. Theme parks, beaches, desert hikes, city walking, outdoor sports, and long road trips can mean hours under direct sun. Visitors may burn faster than expected, especially in places with dry heat or little shade.

The need depends heavily on region, season, altitude, and activity, but the U.S. includes many very sunny climates. States in the South, Southwest, Mountain West, and along the coasts can expose people to strong UV levels. Outdoor tourism is also huge, so sunscreen became a practical part of American vacation advice.
