For the majority, extended sun exposure is not of great concern. Infants and people with sensitive skin must always be protected. The Sun is most powerful around mid-day, so it's a good practice to reduce direct 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. Mind this! Nearly twice the UV radiation from the Sun can be reflected by the snow.
