What is ultraviolet ray (UV)?
The wavelengths of the sun’s rays in the range of 280-400 nanometers are known as ultraviolet (UV) -A and -Brays. Exposure to these rays leads to the appearance of a sunburn that manifests with early redness and redness of the skin. In addition, skin cancers can cause harmful and dangerous effects, such as various sunspots, allergic symptoms, and the development of certain sunlight-triggered diseases, such as skin immune suppression and premature aging. The World Health Organization defined sun and artificial sun rays (solarium, solar lamps) as lam carcinogen yapay (cancer causing substance).
Is the amount of UV light associated with skin cancer development?
The total amount of ultraviolet radiation that is exposed to life-span and the number of sunburns, especially in childhood, are directly related to the risk of skin cancer development in adulthood. Tanning is caused by the increase of the amount of melanin in the skin (the pigment that gives the color to the skin) as a defense mechanism to prevent further damage due to UV damage of various cells in the skin. By the amount of increased melanin, the skin becomes darker and more UV radiation is prevented from being absorbed. However, this DNA damage is never fully repaired by the body and leads to the development of skin cancers. Children, especially children under 6 months of age, should not be exposed to direct sunlight as the skin of children is much more sensitive to sunlight.
Why should we protect the sun?
The goal of protection from the sun should not only prevent sunburn development, but also prevent the skin from changing color.
Measures to be taken for this purpose;
Avoid being outdoors between 10:00 and 16:00,
Choosing shade areas and using sunglasses with clothing and hats covering the body surface as broadly as possible,
Hats should be wide border to cover the neck and ears,
It is preferred that the garments be chosen from UV-resistant special products or from dark-colored, frequently woven linen and cotton fabrics that pass less than UV, or from fine-textured fabrics made of polyester, lycra, polypropylene,
Sunscreen products should also be used.
The above measures may reduce the risk of ultraviolet-related skin aging and skin cancer development.
