If Out In The Sun Make It Before 10 And After 2 For Times That Lower Health Risks For You


That ball of fiery hydrogen bathes our planet with three major types of UV (ultraviolet) rays. We have met UVA, UVB and UVC in past articles from Renovating Your Mind. No need to worry about UVC because radiation energy is so low that it won’t make it past the earth’s atmosphere. UVA and UVB are a completely different story because they both smash into our skin damaging the baggage that hold us together.

Sunlight, How Best To Limit The Damage


UV-A penetrates car side windows. Studies have shown more damage from radiation on parts of the body closest to the side window. UV-A rays are the most powerful of the three because they go deep into the skin. Although not responsible for the tanning or external visible damage, UV-A increases cancer risk by causing DNA damage within cells that produce skin.

SPF (sun protection factor) is a number listed on sun products illustrating protection from U-VB. The higher the number the more protection. The highest relevant SPF number is 30 where 90% of the U-VB rays are neutralized for a period of 2 hours. You must then reapply to continue with the positive effect. Why? Because the sun starts breaking down the protective chemicals plus sweat dilutes potency over time.

These products absorb the sun’s rays by creating a chemical reaction under your skin. This process gives off heat therefore making you feel warmer.

Application of either zinc oxide or titanium dioxide cause UV-A radiation to bounce off your skin. This doesn’t cause the skin to get hotter because these rays are never absorbed by these products. These UV-A chemicals sit on the top of your skin acting like an umbrella does with rain.

UV-A radiation bouncers were always visible after application because they appeared as a color, usually white. With today’s nanotechnology, scientists are able to break down the particles to a size where they are invisible to the naked eye.

Superior Sunscreen Products

Things To Consider When Shopping For A Sun Product:

  • Wear a sunscreen product that has chemicals that protect against both UV-A and UV-B.
  • Best agent to use to bounce off UV-A rays is zinc oxide (4-5%).
  • Read ingredient labels.
  • SPF 50 blocks 98% of UV-B rays for 2 hours. Higher numbers are harder to apply because of higher concentrations of protective chemicals.
  • Most realistic number is SPF 30 which stops 90% of the rays.

NOTE: DO NOT USE any products containing NANO-PARTICLES of zinc oxide or titanium dioxide that are sprays or aerosols. These small particles can make it down into your lungs. Research is lacking showing safety of these gaseous forms of the chemicals.
