Sun Protection against Ultraviolet Rays


The electromagnetic radiations emitted by the sun have damaging effects on the skin if you do not use some protection against it. These sun radiations affect you in the form of infrared rays, light and ultraviolet rays, also known as UV rays.

It is extremely important to use sun protection against ultraviolet rays because they are thought to be human carcinogen. This also applies to tanning beds. In addition, UV rays are responsible for premature aging skin, wrinkles and age spots. The U.S. Environment Protection Agency has even stated that one in five Americans is likely to have skin cancer in their lifetime. Still, skin cancer can be prevented if you use sun protection against ultraviolet rays.

UV rays are energy coming from the sun transmitted in wavelengths. They are shorter than infrared rays, but more powerful, therefore more damaging. If you do not use sun protection against ultraviolet rays, your skin`s genetic code will be altered, causing cell damage and deformities, as well as eye problems. There are three types of UV rays (UVA, UVB and UVC), but each type is dangerous for the skin.

UV radiations can cause premature skin aging and other skin issues, including skin cancer. The immune system is also suppressed by too much exposure to sun, while eye damages such as pigmentation or cataracts are other negative effects.

Considering the dangers, sun protection against ultraviolet rays is a must. You can still enjoy the sun, but some measures must be taken so that you do not suffer the negative consequences. Use sunscreen with both UVA and UVB protection and ensure its SPF (Sun Protection Factor) is at least 15. Protect exposed skin by wearing long clothing such as a long-sleeved shirt while staying in the sun. You can protect the face and head by wearing a hat with wide brim. Wear sunglasses that block as much as possible the UVA and UVB rays. When possible, stay in shaded places during the noon hours when radiation is at its maximum.
