UV index. Shall you wear a sunscreen today?

UV index - what is it?

It is a "magical number" which helps to decide if you should wear a sunscreen today or not :)

We all know about this default "rule": wear a sunblock in summer + late spring and early autumn.

But did you know that even in summer there are days where there is no need in a sunscreen?

Open the app with the weather forecast and look for "UV index" (if its not there, just Google it adding the name of your town/city).

If you see:
* 1, 2, 3 or 4 - you can leave the house without a sunscreen (yes, even if it is sunny outside);
* 5, 6, 7 - you must use a sunblock and follow all the rules (yes, even if its cloudy outside);
* 8, 9, 10, 11 - try to avoid Sun as much as you can (stay in the building or shadow, wear hats and sunglasses as well as clothing with longer sleeves).

Check the UV index in your city now :)
