For decades, the population of industrialized countries has been brainwashed into thinking the sun is evil. They've been told to cover up their skin and to avoid being exposed to natural sunlight. They've coated themselves with sunscreens (which contain toxic chemicals, by the way), and taken extreme measures to avoid sunlight. This advice, however, has turned out to be completely wrong. Natural sunlight is absolutely essential for good health, and without it, you are far more susceptible to cancer, depression, obesity, osteoporosis and many other diseases. Sunlight is a natural cure that helps the body maintain a high state of health.
But what about sunburns, you ask? I speak from experience on this issue: people are only susceptible to sunburns when they have nutritional deficiencies caused by consuming soft drinks, processed foods, white flour, refined sugars, and other similar substances. A person on the standard American diet receives a sunburn very easily. But if that same person follows a sound diet for several months, avoids all processed foods and supplements their diet with nutritional supplements and superfoods, they will not burn their skin in the sunlight.
On the Vitamin D issue, deficiencies in this vitamin are widespread. As a result, perhaps tens of millions of men each year are killed by a completely avoidable disease: prostate cancer. With sufficient Vitamin D from cod liver oil or natural sunlight, very few men ever experience prostate cancer. With women, it's breast cancer and osteoporosis: both diseases are entirely preventable, and sunlight is one of the keys to this prevention.
It's sad that many doctors are still telling their patients to avoid the sun. It is precisely the sun that holds the cure to many diseases now considered epidemic in the Western world. We need more sunshine, not less, and while there is certainly such a thing as too much sunshine in one setting, the fact is that almost nobody living in modern cities gets even the minimum daily requirement of sunshine.
By the way, this is even more true for people who have darker skin. Those of African descent are especially prone to Vitamin D deficiencies since their skin naturally blocks a significant portion of sunlight radiation. That's why black men have a much higher rate of prostate cancer than white men. Furthermore, black men who live in Northern climates (like London or Canada, for example) have it even worse: it's virtually impossible for them to get enough Vitamin D since there's not much sun to be found where they live. (Keep in mind: dark skin was an adaptation for people living near the equator, where sunshine is far more powerful.)
Back to the research: it's fascinating that modern medicine is now finding that the body cures its own cancer if given the raw ingredients it needs. Breast tissues have their own miniature chemotherapy factories, you might say, and if a tumor appears, they fight it off before it can ever be diagnosed by a mammogram. Truly, the human body is a miracle of nature, and your body knows how to cure cancer on its own. If you want to be free of breast cancer, simply feed your body the nutrition it needs to invoke its own innate healing abilities.
