The Healing Sun: Reduce Your Risk of Cancer with Natural Rays

Taking a daily 10- to 15-minute walk in natural sunlight not only clears our head, relieves stress and increases circulation, it could also cut the risk of breast cancer at least 30 to 40 percent according to epidemiologist Esther John at the Northern California Cancer Center. A host of studies back her up.
In The Breast Cancer Prevention Diet, Dr. Robert Arnot observes that breast cancer occurs at higher rates in the cloudy north than the sunny south. A 10-year study by Johns Hopkins University Medical School further suggests that exposure to full-spectrum light positively relates to prevention of breast, colon and rectal cancers.
Research shows that the number of people who die from breast, colon, prostate and ovarian cancers, multiple sclerosis and osteoporosis–all maladies sunlight could benefit–is far greater than the number of deaths from skin cancer. After reviewing 50 years of medical literature on cancer, Dr. Gordon Ainsleigh concluded that “the benefits of regular sun exposure outweigh the risks of skin cancer, accelerated ageing and melanoma.”
The secret lies in how sunlight stimulates responses in the body that trigger production of vitamin D3, a type of steroid hormone that can dramatically improve immune system function. It also inhibits the growth of cancer cells. Physicians warn that high doses of D3 tend to be toxic, so we need to exercise common sense. But Dr. Richard Hobday, author of The Healing Sun says that modern-day fear of sun exposure and everyday use of sunscreens has done more harm than good.
