What you need to know about protection from the sun

Whether it’s “fun in the sun” or “work in the sun,” protection from ultraviolet rays of the sun is important for everyone – both children and adults. 

“Many of us use it but the selections in the aisle of the store can be confusing. It’s hard to decide which SPF to use and whether you need protection against UVA, UVB or both,” said Renette Wardlow, a human development specialist with University of Missouri Extension. 

UVA and UVB are types of ultraviolet radiation. Humans need protection against ultraviolet radiation because it contributes to conditions such a premature skin aging, eye damage and skin cancer. These types of ultraviolet radiation can also suppress the immune system making it difficult to fight these conditions. 

The U.S. Department of Health and Human Services and the World Health Organization recognize UV as a proven carcinogen. 

UVA rays are 30 to 50 times more prevalent than UVB rays. UVA rays penetrate the skin more deeply than UVB and this contributes to skin aging. 

“We used to believe that aging was the worst damage that UVA could do. We now know that UVA rays damage skin cells in the basal layer of the epidermis where most skin cancers occur. We now know that UVA can contribute to and may even initiate the development of skin cancers,” said Wardlow. 

UVA is the ray that makes humans tan. Tanning in the sun or in a salon can cause damage over time which can lead to skin cancer. 

UVB rays are the ones that cause sunburn. It has long been known that UVB rays play an important role in the development of skin cancer.
