    Don't forget about UV light this season

Winter sun safety
Don't forget about UV light this season

Woman in snow
Even on the snowiest winter days, UV radiation can still be damaging.

Overcast conditions and the winter chill usually don’t inspire the need to check UV levels, but even at this time of the year precautions should be taken.

Believe it or not roughly 90% of UV light can cut through clouds, it can even bounce off puddles and snow so don’t assume it is safe to head out without sunscreen just because it’s a grey day.

You may also assume that it is safe if it is cold. UV rays have nothing to do with the heat emitted by the Sun. It can be in the minus temperatures and still be dangerous due to UV.

When is it safe?

The UV-Index rating makes it easy to see when protection is required. Any day with an index of three or higher you should use sunscreen.

You can check the UV-Index rating near you daily within your local forecast information on the Weather & Radar app.
