Extended sunlight exposure does not pose significant problems for most people, except for children, infants, and people with fair skin who always need shielding. The Sun's most intense and consequently most harmful UV radiation during midday hours should be decreased by minimizing exposure and seeking shade. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Be alert to the fact! The reflection from snow can nearly double the UV radiation of the Sun.
