The sun no doubt is a good source of vitamin D, but over exposure to it can cause so many hazards.

Part of the light that radiates from the sun consists of ultra- violet rays. The rays cause tan, and other skin damage.

There are three types of rays from the sunlight. They are ultra violet A-rays (UVA); ultra violet B- rays (UVB) and ultra violet C-rays (UVC).

The UVC rays, which are lo called the tanning rays, have long wavelength that penetrate deep into your skin. They tan your kin but do not burn you. Over exposure to UVA rays can lead to long-term skin damage.

UVB rays have short wavelengths that affect the outer most layer of the skin. They are known as the burning rays because they are more responsible for burning of the skin.

UVC is the most dangerous. Fortunately, the rays are blocked by the ozone layer and they don’t reach the earth. So the major concern is only the outer types of rays.

Although UVB is the more harmful type of radiation, UVA is linked with immune system damage and a fatal cancer called malignant melanoma. Melanoma is now the most common and deadliest form of skin cancer in women aged 25-29.

Researcher’s also say that since UVA rays penetrate deep into the skin, they destroy skin fibers and damage elasticity. This cause premature aging, wrinkle and the skin becoming leathery. Light skin is susceptible to sun burn damage, but dark skin can burn also develop painful sun burns.

So, when next you are going under the rays, get protected. Shield your eyes with a pair of sunglasses; put on a sunscreen (either lotion, spry or gel) with at least SPF 30 and make sure you wear protective clothing.
