A sunburn is redness and swelling of the skin from overexposure to ultraviolet (UV) radiation.[1] Onset is often 2 to 6 hours after exposure.[1] Other symptoms may include pain, warmth, and blistering.[1] After a few days skin peeling may occur.[1] Complications can include dehydration, infection, skin cancer, skin aging, and brown spots.[1]
It most commonly occurs due to Sun exposure, though can also result from other sources like tanning salons.[1] Those with lighter skin are more likely to sunburn.[1] Other risk factors include living near the equator, high elevation, between 10 am and 2 pm, clear skies, reflection from snow, and certain medications.[1][2] Medications involved may include doxycycline and HCTZ.[2] The underlying mechanism of injury involves DNA damage followed by programmed cell death.[2]
Preventive measures including avoiding the Sun around midday, sunscreen, and sun protective clothing.[1] Treatment involves pain medication such as NSAIDs and moisturizer.[1][2] A severe sunburn may required intravenous fluids such as Ringer's lactate.[2]
Sunburns affected about 34% of the population of the United States in 2015.[2] Young adults are most commonly affected.[2] Before 1820 it was believed that sunburns were due to heat.[3] Sunscreen was initially developed during World War Two.[3]
