Dangers from the Sun's UV Rays

We all know those familiar heat safety rule -- drink plenty of water, take frequent breaks, and avoid the hottest part of the afternoon.. However, there is something else to remember.

The ultraviolet rays from the sun can pose a problem for our bodies. Prolonged exposure to the sun's UV rays can lead to skin cancer, and that is why you want to make sure you have plenty of sun block on hand for all those outdoor activiites.

Dr. John Wolf, a dermatologist at the Baylor College of Medicine says, "Children, and adults alike, need to be using an effective sunscreen every time they go outside. I recommend, and most dermatologists recommend using a daily application of a sunscreen with an spf, or sun protection factor of at least 15."  Dermatologists like Dr. Wolf recommend that you apply sunblock before going outside and that you reapply every two hours.

Parents, make sure your children don't forget these rules either.  Dr. Wolf says, "Anyone who has three or more blistering sunburns in childhood is considered to be at a greater risk of developing melanoma."

To help us gauge the dangers of UV rays, the Environmental Protection Agency, or the EPA, has designed the UV index which rates the daily UV danger on a scale of 1 to 11. You can find the daily UV forecast by clicking the Weather and Your Health link from our weather page at ktre.com.
