New findings have emerged in the field of sunburns, the painful yet protective immune response from ultraviolet (UV) radiation. The skin turns reddish and becomes hot to the touch, making it very uncomfortable. UV radiation can also cause general fatigue, mild dizziness, and possible skin diseases. A new study from the University of California (UC) San Diego has found that the sunburn is actually a consequence of RNA damage to skin cells. This finding may possibly lead to new treatments for blocking the inflammatory process, plus a range of other medical conditions.
