Can I get sunburnt in winter?

Very easily! Always take precautions against the strength of the sun on a skiing holiday. At altitude and with the reflection off the snow, the sun’s rays can cause damage very quickly. Always, always wear sunglasses, even when the sun is not shining. Apply sunscreen, apply it thickly and keep applying it (you can still burn though cloud cover). Putting on factor 40 once in the morning will not protect you from burning. Reapply every hour.
