What Are UVB Rays?

  • In places closer to the equator




Effects Of Ultraviolet Rays


When these 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 looking 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 sunburned 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).

Ultraviolet Light 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.
