This situation increases the risk of skin cancer and of sunburn. Long exposure to the sun may inflame your skin and cause it to swell. Even longer exposure results in burning, with blistering and peeling, and possibly heatstroke, which causes the temperature-regulating mechanism of your body to give up, which can make you very sick. Of course the most serious danger of sun tanning is the risk of skin cancer, which is higher in pale-skinned people. As you know, skin cancer has increased significantly in the last few years and this is almost entirely due to our obsession with a tan.
Sunblocks are a necessity.
Another long-term hazard is wrinkles, which are caused by the sun destroying the collagen in the skin. Instead, protect your skin with the sunscreens in strong sun light. If you really must get a tan, use common sense and learn all you can about sun screens. and tan gradually over a period of time, with short session of exposure to the sun. BUT no amount of tanning is safe for your skin. Sunscreens block the harmful UVA and UVB rays of the sun.
