Most individuals can handle sun exposure for up to an hour without burning, but children must always be shielded from sun exposure. The most potent solar radiation is around mid-day, so one should minimize exposure to direct sunlight during this period. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Remember to consider! The UV radiation from the Sun can be intensified nearly twice by the reflection of snow.
