Solar erythema

From WikiMD's Wellnesspedia

Solar erythema (also known as sunburn) is a type of erythema that results from an inflammatory reaction in response to exposure to ultraviolet radiation, particularly the UVB spectrum of sunlight.

Causes[edit | edit source]

Solar erythema is caused by exposure to the ultraviolet (UV) radiation from the sun. The UV radiation damages the DNA in the skin cells, leading to the release of cytokines that cause the blood vessels to dilate and become more permeable. This results in redness, swelling, and pain, which are the hallmarks of inflammation.

Symptoms[edit | edit source]

The symptoms of solar erythema include redness, swelling, and pain in the affected area. In severe cases, blisters may form. The symptoms usually appear a few hours after sun exposure and peak after 24 to 36 hours.

Prevention[edit | edit source]

Prevention of solar erythema involves avoiding excessive sun exposure, especially during the peak hours of UV radiation (10 a.m. to 4 p.m.). Wearing protective clothing and using a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 30 can also help prevent sunburn.

Treatment[edit | edit source]

Treatment for solar erythema primarily involves relieving the symptoms. This can be achieved through the use of over-the-counter pain relievers, cool compresses, and aloe vera gel. In severe cases, medical attention may be required.
