UV Protection
What does UV Protection mean to you?
Sunlight consists of two types of harmful rays – UVA rays and UVB rays. The UVB rays are the sun’s burning rays (which are blocked by window glass) and are the primary cause of sunburn and skin cancer. UVA rays (which pass through window glass) penetrate deeper into the dermis, or base layer of the skin. UVA rays are known for causing wrinkles in your skin. The Sun Protection Factor (SPF) system currently used to rate the strength of sunscreens measures their ability to provide UVB protection, which helps prevent sunburn.
UV Protection stands for ultraviolet protection. UV Protection is broad-spectrum protection from both UVA and UVB rays that reach the Earths surface. When considering proper UV Protection look for sunscreens that protect against both UVA and UVB rays. Dermatologists have stated that the best UV Protection while your outdoors is a broad-spectrum sunscreen with at least SPF-15 UV Protection.
A sunscreen’s SPF number does not measure the amount of UV Protection it provides from UVA rays, which can cause immunosuppression – or the weakening of the body’s ability to protect itself from cancer and other diseases. Since UVA protection is not measured in a sunscreen’s SPF rating, it is possible that even though a person is getting adequate UVB protection to prevent sunburn the UVA rays can still cause unseen damage below the skin’s surface that could cause skin cancer.
Recent studies have demonstrated that broad-spectrum UV Protection sunscreens (which provide both UVB and UVA protection) with an SPF of 15 or higher, while providing adequate UVB protection may not have a corresponding level of UVA protection. In fact, one new study demonstrated that the amount of protection from immunosuppression caused by UVA rays that is obtained from the average broad-spectrum sunscreen is more than 50 percent lower than its sun burning protection unless separate UVA protective ingredients are used as additives.
UV Protection Guidelines
It is recommended that everyone follow these UV Protection guidelines:
- Avoid outdoor activities between 10 a.m. and 4 p.m. when the sun’s rays are the strongest
- Seek shade whenever possible; Wear a broad-spectrum sunscreen with a Sun Protection Factor (SPF) of 15 or higher.
- Wear sun-protective clothing and accessories, such as wide-brimmed hats and sunglasses.
- Follow the “Shadow Rule” – if your shadow is shorter than you are, the sun’s damaging rays are at their strongest and you are likely to sunburn.
