Why does the body shed or peel away sunburned skin?

The body sheds or peels away sunburned skin as a natural healing response to damage caused by UV radiation. sunburn damages the skin cells, leading to inflammation and the release of chemicals that signal the need for repair. As the skin heals, dead or damaged cells are sloughed off to make way for new, healthy skin. This process helps to protect the deeper layers of skin and prevent further complications, such as infections.
