|ABOUT THE SUN'S UV RAYS
Natural sunlight is important for good health. But too much exposure to the sun’s rays increases your risk of skin cancer, eye problems, such as cataracts, and can suppress the skin’s immune system.
We are exposed to more ultraviolet (UV) rays as the protective layer of ozone around the earth becomes thinner due to the effects of pollution and chemicals.
Up to 80% of the sun’s rays travel through light clouds, haze, mist and fog. Water, sand and concrete can reflect, and even increase, the sun’s rays.
In winter, the sun’s rays reflect off the bright surface of the snow, just like they reflect off sand and water in the summer. Reflection off the snow can nearly double the strength of UV rays. The problem is worse at higher elevations.
Protect your skin by practising sun safety all year round.
