Extended sun exposure is not an issue for the majority. Children, infants, and fair-skinned individuals always need to be protected. The most potent solar radiation is around mid-day, so one should minimize exposure to direct sunlight during this period. 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. Heed this! Snow reflection can almost augment the UV radiation of the sun by double.
