What Are UVB Rays?

"The Burning Rays"

UVB rays are ultraviolet light coming from the sun, and has a wavelength variation from 290nm to 320nm. This rays are shorter but stronger than uva rays. They affect the skin's outer layer, causing dehydration to the epidermis.

Part of these rays can penetrate deeper into the skin, changing the structure of the cells, and are also are linked to

skin cancer
cataracts
and are the main responsible for causing sunburn

Sunburn is the skin's natural defence against overexposure to uvb rays. This rays are stronger

in the summer than in winter
when the Earth rotates closer to the sun
at higher altitud
at midday
in places closer to the equator

When this rays reach the skin, they begin damaging the skin cells in the epidermis. In response, the inmune system increases blood flow to the affected areas, making the skin feel warm and look red. White blood cells, which help protect from infection and disease, attack and remove the damaged cells. This process can cause the skin to itch and peel.

It can take up to eight hours for the full effects of sunburn to be notice, so you won't realize that you have been burned right away.

A mild sunburn can be treated with cool baths, over the counter hydrocortisone creams and aspirin, to ease pain and swelling, according to the American Academy of Dermatology (AAD).

A severe sunburn, usually characterized by a large area of red, blistered skin with headache, fever and chills should be treated as a medical emergency, and examined by a doctor right away.
