The condition that involves excessive exposure to ultraviolet light is known as sunburn. It occurs when skin cells are damaged by UV radiation, leading to inflammation, pain, and redness. Prolonged UV exposure can also contribute to long-term skin damage, including premature aging and an increased risk of skin cancer. This is due to the DNA changes in skin cells caused by UV radiation. Protecting the skin from excessive UV exposure through sunscreen and protective clothing is essential to mitigate these risks and maintain skin health.
