While extended sun exposure does not significantly affect most people, those with sensitive skin, children, and infants should always be protected. The mid-day Sun emits the most powerful UV radiation, so seek shade and minimize exposure. Opt for tightly woven and loose clothing to enhance protection from the Sun. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
