Sunlight, Sunscreen Healthful or Harmful?
You Need Sunlight
How often have you heard that the sun is harmful, it causes cancer and that you need to put on sunscreen? Both are more examples of health myths that are perpetuated by the pharmaceutical industry and by the uniformed medical establishment.
All life on earth depends upon the sun. Without the sun there would be no plants, no food and no energy. It’s no wonder many ancient cultures treated the sun as a god.
Throughout history it has been used to prevent and cure a wide range of diseases. It kills bacteria and there is much new evidence that it actually prevents many types of breast, colon, prostate and ovarian cancers, heart disease, osteoporosis and multiple sclerosis. Sunlight is also good, not bad for the eyes. Over use of sunglasses also restricts the amount of healthy sunlight needed by the eyes and the entire body.
UVA and UVB Radiation
UVA sunrays have a constant intensity throughout the day and penetrate the skin deeply and cause more free radical damage, which can lead to skin cancer.
UVB sunrays are less problematic because they are only at high intensity between 10 am and 2 pm and they actually help your body to produce Vitamin D. So 10-2 pm is actually the best time to be in the sun for vitamin D production.
Sun exposure does not necessarily lead to skin cancer. There was a definitive study of Australian life guards, which showed they had less skin cancer than the general population. One’s overall lifestyle, primarily poor nutrition, is the major factor in developing any disease.
Melanoma, the only deadly form of skin cancer, actually occurs most often on unexposed parts of the body, which leaves doubt as to the actual cause.
Too much exposure and sunburn can lead to skin cancers for those most susceptible, primarily people with fair skin. However as previously mentioned the cancer prevention qualities of sunlight far outweigh the potential hazards.
Sunscreens Are Questionable At Best
Sunscreens have been touted as necessary to prevent skin cancer. In fact most of them contain toxic chemicals that actually can contribute to causing internal cancers and they are not 100% efficient at preventing sunburn. Many people using sunscreen have a false sense of security and tend to stay out in the sun too long. There are some non toxic, natural sunscreens available but I do not know how effective they are. Your best bet for an extended sun exposure is to use sun block. Titanium oxide and zinc oxide are two natural mineral compounds that have been used safely for many years as an effective sun block.
Vitamin D is What You Need
Vitamin D is an essential nutrient that the body requires to produce healthy bones and prevent many serious types of cancer. There are studies that show there are many more cases of vitamin D deficiency for people living in northern latitudes compared to those living in southern, sunnier latitudes. There are also many more cases in northern latitudes of osteoporosis, depression and many forms of cancers. These facts suggest a strong correlation between vitamin D deficiency and many diseases.
Your body can only produce a sufficient amount of vitamin D from having regular sunlight exposure. Vitamin D supplementation, up to 1000I.U. and sun lamp use is necessary for those who do not get regular sun exposure.
1. Do not fear the sun, enjoy the sun daily.
2. Do not over do it, sunburn is never good
3. Use natural sun screens and blocks for UVA and protective clothing for extended sun exposures.
4. Use sun glasses primarily when there is a glare, such as on the water or snow.
5. Supplement with Vitamin D if you do not get regular sun exposure.
6. Reduce omega-6-fats found in vegetable oils and increase omega-3-fats found in fish and seed oils.
