Mystery of the Internal Vibration

Entry for August 12, 2007


The Morning After:

Woke up and the only place that was slightly burnt was the top of my shoulders. No visible burn on my chest or my back. Nothing! My wife had the same thing and Natalie with no sunblock whatsoever showed no visible tan anywhere. I was slightly shocked but more proud that it did work again using vitamins as a natural sunblock. My daughter drinks three to four glasses of goat’s milk a day and she probably had plenty of vitamin D for sun protection.

So if none of us got any kind of sunburn, what exactly does sunblock do?

Sunscreen may actually increase the risk of cancer, so proposed California researchers in a paper published in January, 1993, in the Annals of Epidemiology. The researchers contended that UVB- blocking sunscreens had contributed to increasing skin-cancer rates, by disabling the body’s natural alarm mechanism: sunburn. The researchers also posited that because UVB rays are the main source of vitamin D, and because vitamin D may inhibit the progression of melanoma, and because sunscreens block UVB rays- sunscreens might promote vitamin D deficiencies and cause melanomas. (UVB is the shorter wavelength of ultraviolet light that damages the skin. UVA is the longer of the two types of ultraviolet light that reaches the earth. UVA is responsible for tanning.)

In a study in the Journal of the National Cancer Institute in January,1993, researchers from the University of Texas M.D. Anderson Cancer Center applied three common types of sunscreen to mice and then exposed most of them to sunlamps twice a week for three weeks. Melanoma cells were then injected into all the mice. The mice exposed to the ultraviolet (UV) rays, even if they were treated with sunscreen, had a higher incidence of melanoma than those not exposed to UV rays. The researchers theorized that sunscreens may allow enough UV to penetrate the skin to suppress the immune response and/or damage DNA, thus allowing tumors to develop.

UVA can cause skin cancer, particularly melanoma, according to the Texas researchers. The sunscreens used in the mouse study blocked little or no UVA.
