In contrast to children, who must always be shielded from the sun, most people can tolerate up to an hour of sun exposure without any burns. 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. Mark this! Snow reflection can nearly double the UV radiation intensity from the Sun.
