Sun rays are one of the indispensable elements of life, such as air and water. With the effect of sunlight, vitamin D synthesis, which is necessary for healthy ossification, takes place in the skin. It is also known for its healing effects in some diseases such as psoriasis and adolescent acne. It is also known that UV rays provide positive psychological effects.
However, due to the fact that the most common type of cancer today is skin cancer and the most common cause of skin cancers is UV rays, adequate protection must be fulfilled absolutely. If the sun is not sufficiently protected from the sun, the possible dangers are sunburns, staining, skin changes called photoaging, cataract formation in the eyes and most importantly the development of skin cancer. When we consider that the sun is very generous to our country, the importance of protection becomes even more obvious.
UV rays constitute only 5% of solar rays reaching the earth. It consists of 95% UVA and 5% UVB rays. While the ozone layer in the stratosphere completely blocks UVC and partially blocks UVB, all of the UVA reaches the earth. The carcinogenic effect of UV occurs at wavelengths of 290-400 nm. Chemical agents responsible for damage to the ozone layer. These are the chlorofluorocarbon group gases found in aerosol sprays and freezers. As the filtering effect decreases with the damage to the ozone layer, more harmful rays have begun to come to the earth. In a study conducted in Norway in 1992, it was reported that the incidence of SCC in both sexes would increase by 16 to 18% with 10% damage to the ozone layer.
Snowy surfaces reflect 80-90% of UV rays, while this rate is 20% on sandy surfaces.
Skin cancers are generally more common in races with light-colored eyes and light-colored skin. Since Turks are generally wheat-skinned, dark-eyed and dark-haired, they can be considered lucky in terms of skin cancer. However, it is quite common in people with fair skin and eyes.
