A recent study in the journal Blood, shows a remarkable reduction of the risk of a group of cancers known as lymphoid malignancies, i.e. non-Hodgkins Lymphoma, multiple myeloma and classical Hodgkin’s Lymphoma. Researchers in California measured exposure to sunlight among residents in different geographic areas and compared the different categories of exposure to the risk of contracting these cancers.[i] Those residents living in the areas with the highest quartile (fourth) of sunlight exposure, when compared with those in the lowest quartile, showed a 43% reduced risk of Non-Hodgkin lymphoma and a 64% reduction of risk of one of its subcategories known as diffuse large B-cell lymphoma. The risk of another subcategory, chronic lymphocytic leukemia/small lymphocytic lymphoma, showed a 54% reduced risk. Multiple myeloma was also associated with a reduced risk of 43% among those living in areas with the highest quartile of sunlight exposure. Interestingly, dietary vitamin D was not associated with the risk of these cancers. The researchers stated, “These results support a protective effect of routine residential UVR exposure against lymphomagenesis through mechanisms possibly independent of vitamin D
This last finding is doubly important, since it indicates that sunlight exposure may have protective effects against cancers independent of its stimulation of vitamin D production by skin, or that the type of vitamin D produced by sunlight stimulation of skin is superior to that obtained through food or supplements. It appears that Mother nature know best, and that sunlight, one of God’s greatest gifts to mankind, should not be ignored a as preventive therapy.

Low vitamin D, which is primarily a result of low sunlight exposure, is closely related to the ability to conceive in both women and men. Couples spend thousands of dollars on fertility clinics when perhaps all they need is some time in the sun.
People living in the northern (sunniest) area of Australia, have a much smaller risk of allergies and eczema than those living in the southern area. Greater vitamin D levels due to sunlight exposure may be one of the major reasons. Safe sunlight exposure is absolutely essential to your health!
The evidence mounts that high levels of sunlight exposure may predict a 52% reduction in the risk of Crohn’s disease and a 38% reduction in the risk of ulcerative colitis. So why does much of the medical community still recommend that we avoid sunlight exposure?
This article from a Canadian newspaper does an excellent job making the case that midday sunlight exposue is best for good health, and that sunlight prevents cancer. Truth does ultimately win the day!
The following article is well-written and provides a history of sunlight as it relates to the discovery of vitamin D. The author indicates that vitamin D fortification had made rickets a thing of the past, but with that point I disagree. Rickets is making a comeback due to the sunlight phobia promoted by dermatologists. Nevertheless, the article is well-worth reading.

Not only is having a green thumb a great way to stay healthier and happier, but new research shows it can actually protect you from cancer.
Noted cancer treatment and research center M.D. Anderson, at the University of Texas, found in a study that time spent gardening once or twice a week can reduce the risk of cancer by 50 percent in lifelong nonsmokers. Moreover, researchers found, the same level of gardening activity by former smokers can reduce cancer risk by as much as 40 percent.
And while researchers said they weren’t exactly sure if gardening reduced the incidence of cancer more than other physical activities, they did find that it was the most commonly shared trait among the study’s participants.
The cancer-prevention benefits of gardening are also echoed by the American Institute of Cancer Research, which said that gardening is a physical activity that not only helps prevent cancer but also contributes to overall health and endurance.
People who garden tend to eat better food – food that is untainted by chemicals and poisons and food that is much tastier than what you’re used to buying in a supermarket.
Along those lines, gardening means exposure to the sun and its known vitamin D-supplying qualities that have been linked to the prevention of some cancers and a wide variety of other illnesses and diseases.
In fact, along the lines of exposure to the sun, scientists now believe that exposure can actually help prevent skin cancer because sunlight exposure helps in the body’s manufacture of vitamin D, a cancer-stunting agent in its own right.
“Melanoma (skin cancer) patients tend to avoid the sun as sunburn is known to increase the risk of melanoma. We use sunshine to make vitamin D in the skin, so melanoma patients’ levels of vitamin D may be especially low,” said Prof. Julia Newton Bishop of the Leeds Institute of Molecular Medicine, and lead author of a recent study which found that higher levels of vitamin D were linked with better skin cancer survival odds.
Another reason why gardening may contain some anti-cancer, better health qualities, is because contact with soil, and the nutrients it supplies our garden-grown fruits and vegetables, tends to be good for us as well.
Finally, home-grown vegetables also contain anti-cancer nutrients and flavonols that can decrease certain cancers, like pancreatic cancer.
You may have thought you didn’t have a thumb that was green enough to be able to grow your own food, but based on continuing research that verifies the healthy, cancer-busting qualities of such a wonderful, self-fulfilling activity, doesn’t learning how sound like a fantastic opportunity to stay healthy?
