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 :)
