For the majority, extended sun exposure is not of great concern. Infants and people with sensitive skin must always be protected.

On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
