Your phone is the easiest way to protect your skin from the sun

Summer is here and it’s so good to be basking in the sun on your deck or on a sandy beach somewhere.

But its so important to be aware of sun exposure to your skin to keep from getting sunburned or even cancer. And there are many ways to do that and one of them just happens to be on your cell phone device.

The risks come from overexposure to ultra-violet (UV) rays from the sun and could for many, counter the feel-good feelings from frolicking or lounging in the sun.

There are three different types of UV rays or radiation that are emitted from the sun: UVA, UVB, UVC. We don’t have to worry about the UVC rays as they are consumed by the earth’s atmosphere. But UVA and UVB rays reach our skin and 95 percent of the suns rays are UVA but they are not the cause for sunburn. No, UVB, although with only 5 percent is the cause for burning your skin.

So the danger that comes from too much exposure to UVB can be the acceleration of skin aging like wrinkles, age spots and loss of elasticity, as well as suppressing some of your immune functions, and the possible development of skin cancer. Not to mention UV rays can damage DNA,which can then lead to unchecked cell growth and cancer, reports Dr. Richard Torbeck, who is a dermatologist in New York.

Another things is that excessive exposure to UV radiation can lead to eye complications such as cataracts and corneal sunburn and damage to the retina, according to Dr. David Lortscher, who is the board-certified dermatologist leading the skincare startup, Curology

Three well known organizations have declared that UV radiation is a carcinogen whether it comes naturally and directly from the sun or through artificial tanning beds or booths. Those organizations are The US Department of Health & Human Services, the US Food and Drug Administration (FDC) and the World Health Organization (WHO).

Another organization, the American Academy of Ophthalmology (AAO), recommends that you protect your eyes from UV exposure by purchasing and using UV-blocking sunglasses and wearing hats. 

To protect your skin from excessive exposure to UVB radiation, you can use your iPhone Weather app, which will give you a daily UV index. Dr. Torbeck uses it daily because he says the UV index can change due to clouds, wind or your distance from the equator and ozone holes in the stratosphere.

Knowing the UV index for the day can tell you how much sunscreen to apply and how often in order to protect your skin from sun damage.
