Sunlight’s good for your skin and critical to your overall health and well-being.
Get enough of it, and you’ll actually reduce your risk for a wide range of cancers. What sunscreens are very good at is blocking UVA rays. Yet even that presents a problem, because your skin needs exposure to UVA rays to make vitamin D.
That’s a huge problem, because vitamin D is a vitally important nutrient that insures healthy function in just about every system in your body.
Vitamin D’s also the most potent cancer fighter in the world. A report came out of a Nebraska university showing that vitamin D has the potential to lower the risk of all cancers in women over 50 by 77 percent. 1 And in a study published in the journal Anticancer Research last October researchers found that sunlight – about 20 minutes a day for fair-skinned people, and two to four times that much for those with dark skin – can reduce the risk of death from 16 types of cancer, in both men and women. Sunscreens rob you of all these health benefits.

the sun and cancer..
Do you realize that one of the most powerful cures for cancer is streaming over our heads each and every day, free of charge?
It's sunlight, which is astounding in its ability to prevent and cure cancer.
Here is an interesting recent research finding on the sun, vitamin D and cancer:
".......But perhaps the biggest bombshell about vitamin D's effects is about to go off. In June, U.S. researchers will announce the first direct link between cancer prevention and the sunshine vitamin. Their results are nothing short of astounding.
A four-year clinical trial involving 1,200 women found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who didn't take it, a drop so large — twice the impact on cancer attributed to smoking — it almost looks like a typographical error.
Only brief full-body exposures to bright summer sunshine — of 10 or 15 minutes a day — are needed to make high amounts of the vitamin. But most authorities, including Health Canada, have urged a total avoidance of strong sunlight or, alternatively, heavy use of sunscreen. Both recommendations will block almost all vitamin D synthesis.
Those studying the vitamin say the hide-from-sunlight advice has amounted to the health equivalent of a foolish poker trade. Anyone practising sun avoidance has traded the benefit of a reduced risk of skin cancer — which is easy to detect and treat and seldom fatal — for an increased risk of the scary, high-body-count cancers, such as breast, prostate and colon, that appear linked to vitamin D shortages.
The sun advice has been misguided information "of just breathtaking proportions," said John Cannell, head of the Vitamin D Council, a non-profit, California-based organization.
"Fifteen hundred Americans die every year from [skin cancers]. Fifteen hundred Americans die every day from the serious cancers."
So if sunlight were a mainstream drug, it would probably make the cover of Time magazine and be heralded as the greatest medical breakthrough in the history of modern science. It's that good.

UNDER THE SUN
The quesion is what is worse - moderate sun exposure or sunscreen? - read on - do you want to put this on your skin?
Benzophenone and oxybenzone (benzophene 3) are chemicals used in many sunscreens. They are among the most powerful free radical generators known. Another chemical found in sunscreen, Octy Methoxycinnamate (OMC), may be dangerous if it gets into the bloodstream, according to researchers in Norway, after observing its effects on mice. Scientists from the Norwegian Radiation Protection Authority believe that human cells could be damaged if this chemical penetrates into the skin. As far back as the 1970s, Professor Howard Maibach discovered that as much as 35% of sunscreen does enter into the bloodstream and the longer it is on the skin the more is absorbed.
Triethanolamine (TEA) is a chemical found in many sunscreens. When applied topically to female mice, an increase in liver tumors was noted, whereas male mice had a smaller increase in liver tumors but also developed kidney tumors. TEA combined with water or nitrates (often used as a preservative but not required by law to be listed) can produce nitrosomines, which are carcinogenic.
In 1997 sunscreen chemicals such as benzophenone and ethylhexyl-p-methoxycinnimate, and PABA esters such as padimate-o and octyl dimethyl PABA were banned by the European community. Light reflecting substances such as titanium dioxide and zinc oxide were incorporated into sunscreen as well as avobenzone or Parsol 1789. The latter is a chemical which blocks UVA but is also a free radical generator and skin penetrant. In a study conducted at Queens University in Northern Ireland, scientists found that 2-phenylben zimidazole-5-sulfonic acid (PBSA), an ingredient found in some sunscreens, damaged DNA when exposed to light. It is not known if this happens in humans as this research has been done in test tubes thus far.
