L55: Sunburn

Sunburn is a skin condition caused by excessive exposure to the ultraviolet (UV) rays from the sun or artificial sources like tanning beds. This condition can appear in less than 15 minutes, but the full effects are usually visible after 24 hours. Symptoms generally include skin redness, warmth, swelling, and pain. Severe cases of sunburn can cause large blisters and might make the person feel feverish with chills or nausea. Sunburns damage the skin's top layer and can lead to long-term changes in the skin, such as freckles, wrinkles, dark spots, and increased risk of certain types of skin cancer. Both the intensity and duration of UV exposure factor into the severity of sunburn. Even on cloudy days, UV rays can cause sunburns, and they can also reflect off surfaces like water or snow, leading to burns even in shaded areas.
