A long weekend has begun in Poland. Sunny weather is forecast for parts of the country It can even get hot in places. IMGW also warns against a high UV index, which will be recorded today in a large part of the country.

UV index – what is it?

Institute of Meteorology and Water Management (IMGW) shows the daily forecast of the UV index. The UV index is an international standard for measuring the ultraviolet (UV) radiation that the sun emits on a given day at a particular location.

A UV index of 6 to 7 poses a high and very high risk when staying in the sun for a long time. In this case, use sunscreen (at least SPF 15) and wear light-colored clothing and hats. It is worth limiting the time spent in the sun between 11am and 4pm.

Ultraviolet radiation – types

The risk of skin burn, stroke or melanoma is associated with ultraviolet radiation, which has three different wavelengths: UVA, UVB and UVC.

UVA rays are the longest and reach the deep layers of the skin, damaging its collagen fibers and thus accelerating aging and causing wrinkles. They reach the Earth’s surface regardless of whether the sun is shining or is hidden behind clouds. They occur with the same intensity regardless of the weather.

UVB rays are shorter than UVA. Some of it is absorbed by the ozone layer, but most reaches the Earth’s surface. UVB rays tan and cause skin burns. They damage the DNA of cells, which in turn leads to melanoma, the most dangerous type of skin cancer. Their intensity depends on the season and day. They are strongest from April to October between 10am and 4pm.
