UV index – what is it?

The Institute of Meteorology and Water Management (IMGW) presents a 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.

On the other hand, the UV index equal to or higher than 8 informs about a very high risk to our health. Then you should take even more care of the skin, because it can get tanned very quickly, as well as burns.

UV index

According to the forecast for Monday, taking into account the cloudiness, the UV index will be high in most of the country – in the north it will be 6, and in the center, in the east and some western regions – 7. In the south of the country the index will be 8, which means that the threat will be extremely high. Only in the north-west and in points in the south-west the index will be 3 or lower.

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.
