How to use the UV index
The higher the index, the stronger the sun, and the greater the need to take precautions
What to do when the index is between 0 and 2?
UV isn't usually a problem. But be careful when it's bright and there's snow on the ground. Fresh white snow can reflect over 80% of the UV from the sun, meaning you are receiving almost twice as much UV. Special UV sunglasses will help to protect your eyes.
What to do when the index is between 3 and 7?
Take care. Wear big hats and clothes that cover your skin. Put sunscreen on skin that you can't cover. Don't be fooled if it's cool or slightly cloudy. The UV still gets through.
What to do when the index is 8 or more?
Look out! Don't stay too long in the sun, especially between 11 a.m. and 3 p.m. Wear your sunglasses (the special UV ones) and stay in the shade. Put on more sunscreen every 2 hours or after swimming or working up a good sweat. Be especially careful when you're down south on winter holidays. On clear, sunny days in the tropics, the UV Index is normally between 11 and 14.
