Sunburn and Other Sun Reactions of the Skin A. The sun produces invisible rays called ultraviolet-A (UVA) or ultraviolet-B (UVB) that can damage the skin. Too much sun can cause sunburn, skin texture changes, and skin cancers. Rashes also can be attributed to sunlight. Even on cloudy days, UV radiation reaches the earth and can cause skin damage.

Ultraviolet Radiation Most phototherapy and tanning booths use UVA lamps. The photochemical effects of UV radiation can be exacerbated by chemical agents including birth control pills, tetracycline, sulphathizole, cyclamates, antidepressants, coal tar distillates found in antidandruff shampoos, lime oil, and some cosmetics.

Melanoma Both UVA and UVB rays are dangerous to the skin, and can induce skin cancer, including melanoma. Blistering sunburns in early childhood especially increase risk, but sunburns later in life and cumulative exposure also may be factors.

Sunburn A sunburn is reddening of the skin that occurs after you are exposed to the sun or other ultraviolet light. The first signs of a sunburn may not appear for a few hours. The full effect to your skin may not appear for 24 hours or longer. Symptoms of sunburn are usually temporary. But the damage to skin cells is often permanent, which can have serious long-term effects, including skin cancer. By the time the skin starts to become painful and red, the damage has been done. Pain is worst between 6 to 48 hours after sun exposure.

- Because ultraviolet A is weaker than ultraviolet B, scientists long blamed ultraviolet B as the sole culprit in causing skin cancer in persons with a history of sunburn and repeated overexposure to ultraviolet radiation. Recent research, however, has also implicated ultraviolet A as a possible cause of skin cancer. Ultraviolet B rays are more likely than ultraviolet A rays to cause sunburn, but ultraviolet A passes further into the skin. Scientists have long thought that ultraviolet B can cause melanoma and other types of skin cancer. They now think that ultraviolet A may add to skin damage that can lead to cancer.

UV Radiation and Sun Tanning UV Rays — Invisible and Dangerous. UV, or ultraviolet, rays are the sun's invisible burning rays. They can cause sunburns, and in some cases skin cancer. There are three types of UV rays: UVA: Are more constant year-round and penetrate deeper into the skin's layers; UVA rays are also harmful and contribute to burning, premature aging of the skin, and the development of certain forms of skin cancer. UVB: Are the primary cause of sun burning, premature aging of the skin and the development of skin cancer.

Overview Skin layers and melanin. Sunburns are caused by exposure to too much ultraviolet (UV) light. UV radiation is a wavelength of sunlight in a range too short for the human eye to see. Ultraviolet A (UVA) and ultraviolet B (UVB) are the two types of solar radiation most responsible for sunburn. Sunlamps and tanning beds also produce UV light and can cause sunburn. Melanin is the dark pigment in the outer layer of skin (epidermis) that gives your skin its normal color.

What are UV rays? Ultraviolet (UV) radiation is the part of sunlight which causes sunburn, skin damage and skin cancer. Ultraviolet radiation can be broken down into three bands: UVA, UVB, and UVC. The amount of UV rays reaching the Earth’s surface varies throughout the day. The danger period is between 10am and 3pm. These are the hours when skin damage occurs the fastest. On a cloud-free day, we can feel maximum ultraviolet rays. However, ultraviolet levels are not related to the air temperature. There can be high levels of ultraviolet rays on cool days and UV rays still reach the Earth’s surface when there is cloud cover.

The known health effects of UV Sunburn. High doses of UV radiation kill most of the skin cells in the upper skin layer, and cells that are not killed get damaged. In its mildest form, sunburn consists of a reddening of the skin called erythema. This appears shortly after UV radiation exposure and reaches a maximum intensity between 8 and 24 hours.
