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 solar radiation is most powerful near the mid-day, so the exposure to the direct Sun should be reduced accordingly. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Take warning! The intensity of the Sun's UV radiation can be nearly amplified twice due to snow reflection.
