Sunburn is skin damage caused by ultraviolet (UV) rays. It usually causes the skin to become red, sore, warm, tender and occasionally itchy for about a week.
The skin will normally start to flake and peel after a few days and will usually fully heal within seven days.
While sunburn is often short-lived and mild, it’s important to try to avoid it, because it can increase your chances of developing serious health problems, such as skin cancer, in later life.
It’s easy to underestimate your exposure to the sun when outside, as the redness doesn’t usually develop for several hours. Breezes and getting wet (such as going in and out of the sea) may cool your skin, so you don’t realise you’re getting burnt.
You should always be aware of the risk of sunburn if you’re outside in strong sun, and look out for your skin getting hot.
