Unlike children, who always need sun protection, most individuals can remain in the sun for up to an hour without getting burnt. The Sun's most harmful UV rays are emitted around midday; avoid staying outdoors for long during this time. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Be informed! The Sun's UV radiation can be nearly doubled due to the reflection from snow.
