Sun Safety

They’ve learned a thing or two about skin cancer in Australia. The land-down-under has the highest incidence rate of the most deadly form of skin cancer - melanoma - in the world. This is largely attributed to the three factors: Australia is close to the earth’s equator where the sun’s skin damaging ultraviolet rays are the strongest; the thinning of the UV- blocking ozone layer over Australia; and, a large proportion of Australia’s residents are fair-skinned descendents of Northern Europeans.

Despite its risk factors, Australia’s focus on prevention and early detection has led to a steady decline in skin cancer death rates in recent years.

Americans could learn a thing or two from Australians when it comes to preventing this most deadly form of skin cancer as we head into the summer months.

Five steps to reducing the risk of UV sun damage to the skin.

  • seek shade
  • wear sun-protective clothing that covers as much of your body as possible
  • put on a broad-brimmed hat that shades your face and neck
  • wear wrap-around sunglasses
  • apply SPF30+ broad-spectrum water-resistant sunscreen every two hours

To calculate how long it takes you to burn with a specific SPF rated sunscreen use this equation:

(SPF Value) multiplied times (# of minutes it normally takes you to burn without sunscreen)
=
a rough guide for the # of minutes
you can stay in the sun with that SPF sunscreen.

So, if your normal limit in the sun is 10 minutes, a sunscreen rated at SPF 15 would help protect you for 150 minutes or 2.5 hours.

To check that your sunscreen protects you against both Ultraviolet A and B rays, make sure it contains avobenzone, known by the brand name Parsol 1789. This is the only chemical approved by the Food and Drug Administration for UV-A protection.

Keep an eye on the UV Index in your area.

The UV Index is a calculation of intensity of ultra-violet radiation. In Australia, when the UV Index reaches 3, citizens are urged to act “SunSmart” by taking the five steps mentioned above. You can see what the UV Index is in your area by going to the National Weather Service’s Climate Prediction Center web page
