Understanding the Various Rays From the Sun
We do not see them but we're exposed to them daily.
Invisible rays known as ultraviolet (UV) rays that come from the sun are both beneficial and potentially hazardous.
UV rays are helpful in that they assist in the production of vitamin D that keeps our bones and teeth strong.
They strengthen our immunity against diseases such as colon cancer.
UV rays are also used to treat psoriasis - a distressing skin disease characterized by itchy patches.
On the other hand, UV rays can be deadly since they can burn the eyes, hair, and skin, especially if these parts are not properly protected.
Too much sun exposure also leads to premature aging or photo aging - a condition marked by fine wrinkling, dilation of capillaries, and irregular pigmentation or liver spots.
This is evident in people who sunbathe regularly.
Many of them show signs of photo aging early in life before they reach 30 years of age.
In contrast, normal skin ages after 40 years or more.
The two kinds of UV radiation that affect the skin are UV-A and UV-B.
Both can cause many serious conditions like skin cancer, a weakened immune system, premature aging and cataracts.
UV-A rays are not absorbed by the ozone layer which is why they penetrate deep into the skin.
This is responsible for premature aging.
These rays are also present in tanning beds and sunlamps.
UV-B rays are partially absorbed by the ozone layer but that does not make them less dangerous.
This type usually affects the skin surface and is the main cause of sunburn and skin cancer.
The National Cancer Institute revealed that over 600,000 new cases of non-melanoma skin cancer are expected this year.
Of that number, an estimated 1,900 people will die of the disease.
This staggering statistic is evidence that you should protect yourself from the harmful effects of UV rays.
One way of doing this is by wearing sunglasses.
