The sun is necessary for all life on earth, sunshine and light are beneficial to all of us. Above all after the cold and dark months of winter, we feel an increased need to spend time outdoors. However, too much sun can mean inflicting damage on our skin, which can be anything from premature skin ageing to skin cancer.
Do you know how strong the UV radiation is? We can feel the warmth of the sun's rays, we can see visible radiation, but we can neither feel nor see hazardous ultra-violet radiation. But we can measure it! The UV radiation index is a simple unit for measuring the strength of UV radiation.
