A sunburn is a burn to living tissue such as skin produced by overexposure to ultraviolet (UV) radiation, commonly from the sun's rays. Usual mild symptoms in humans and animals are red or reddish skin that is hot to the touch, general fatigue, and mild dizziness. An excess of UV-radiation can be life-threatening in extreme cases. Exposure of the skin to lesser amounts of UV radiation will often produce a suntan.
Excessive UV-radiation is the leading cause of primarily non malignant skin tumors. Sunscreen is widely agreed to prevent sunburn, although a minority of scientists argue that it may not effectively protect against malignant melanoma, which is either caused by a different part of the ultraviolet spectrum or, according to others, not caused by sun exposure at all. Clothing, including hats, is considered the preferred skin protection method. Moderate sun tanning without burning can also prevent subsequent sunburn, as it increases the amount of melanin, a skin photoprotectant pigment that is the skin's natural defense against overexposure. Importantly, sunburn and the increase in melanin production are both triggered by direct DNA damage. When the skin cells' DNA is damaged by UV radiation, type I cell-death is triggered and the skin is replaced. Malignant melanoma may occur as a result of indirect DNA damage if the damage is not properly repaired. Proper repair occurs in the majority of DNA damage, and as a result not every exposure to UV results in cancer. The only cure for sunburn is slow healing, although some skin creams can help with the symptoms.
