Extended time in the sun generally does not harm most, but those with sensitive skin, infants, and children should always be protected. The Sun's most intense and consequently most harmful UV radiation during midday hours should be decreased by minimizing exposure and seeking shade. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Be attentive! The reflective property of snow can nearly double the Sun's UV radiation.
