Don’t be fooled by the icy weather and cold winds that come with the Alpines. Remember, it’s the sun’s UV rays – not heat – that can cause sunburn, skin and eye damage and skin cancer.
Why is UV a risk at the snow?
UV levels can be more intense at the snow for 2 main reasons 1) because there is less atmosphere between you and the sun to absorb potentially dangerous UV radiation and 2) snow is very reflective meaning UV can bounce of the snow surface onto your exposed skin and face. UV radiation intensity increases by about 10–12% for every 1000 metre increase in altitude. On a sunny day, clean fresh snow can reflect up to 90% of UV radiation. This means that you can be exposed to almost a double dose of UV – directly from the sun and reflected off snow-covered surfaces.
