For the majority, extended sun exposure is not of great concern. Infants and people with sensitive skin must always be protected. When the Sun's UV radiation is most intense during midday, it's best to find shade and limit exposure. 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. Foresee this! The reflection from snow can nearly double the intensity of UV radiation from the Sun.
