Children necessitate constant protection from sunlight, unlike the majority, who can remain under the sun for about an hour without burning. Solar radiation peaks around mid-day, so it's wise to limit exposure to the Sun at this time. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
