Health Effects of UV Radiation. ... it causes more than 75 percent of skin cancer deaths. UV exposure and sunburns, particularly during childhood, are risk factors for the disease. Not all melanomas are exclusively sun-related—other possible influences include genetic factors and immune system deficiencies. Nonmelanoma Skin Cancers.
In addition to cancer, exposure to UV rays can cause other health problems. UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. In some people, exposure to UV rays can cause a rash or a type of allergic reaction. ... Certain medical conditions can be made worse by UV radiation. About UV rays and vitamin D.
ULTRAVIOLET RAYS & EYES DISEASES ... susceptible to damage from ultraviolet (UV) light. Scientific research has clearly linked several eye diseases to damage from UV light. These diseases include cataract, macular degeneration, snow-blindness, pterygium and skin cancer, to name a few. ... Cataract reduce vision. The number one cause of ...
UV rays can penetrate and change the structure of skin cells. There are three types of UV rays: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). UVA is the most abundant source of solar radiation at the earth’s surface and penetrates beyond the top layer of human skin. Scientists believe that UVA radiation can cause damage ...
UV-sensitive syndrome is a condition that is characterized by sensitivity to the ultraviolet (UV) rays in sunlight. Even a small amount of sun exposure can cause a sunburn in affected individuals. In addition, these individuals can have freckles, dryness, or changes in coloring (pigmentation) on sun-exposed areas of skin after repeated exposure.
cancer is the main disease caused by uv rays.
Ultraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women, according to a study by researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health.
Ultraviolet (UV) radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the ...
UV-B radiation also contributes to the development of melanoma skin cancer and can reduce immunity to infectious agents. UV-B radiation may also affect human health indirectly by interfering with the food chain. On a global scale, UV-B radiation may increase the infectious disease burden, cause blindness, and reduce the world's food supply.
The report, Global Burden of Disease of Solar Ultraviolet Radiation estimates that up to 60,000 deaths a year worldwide are caused by too much exposure to ultraviolet radiation (UVR). Of those 60,000 deaths, an estimated 48,000 are caused by malignant melanomas, and 12,000 by skin carcinomas.
