Vitamin D Society recommends Summer Sun to build up D Levels.

By Marc Sorenson, EdD. Sunlight Institute…

Canada has a long season each year in which vitamin D from sunlight is not available. Due to the northern latitude of Canada, May through October is the only period when vitamin D can be produced in response to sun exposure to the skin. Therefore, a new press release from the Vitamin D Society recommends to protect health by building up vitamin D during the summer. Vitamin D from the summer sun helps to prevent serious diseases such as cancer, cardiovascular diseases, diabetes, multiple sclerosis and others.

Dr. Reinhold Vieth, the scientific advisor for the Society, states the following: We often assume that the health benefits of sunshine are solely due to vitamin D, but that is not proven yet.  In other words, it is likely that sunshine does more for our bodies than just produce vitamin D.”

Dr. Vieth is correct. Vitamin D is only one of several products of sun exposure. Others are nitric oxide, which helps prevent vascular problems, and serotonin and endorphins that enhance mood. It is likely that there are many more products of sun exposure that enhance human health.

The Society recommends 6 guidelines for safely enjoying the sun and its health benefits:

  1. Be moderate, and don’t burn.
  2. Sun exposure can produce vitamin D only during the mid-day hours, so be outside between 10 AM and 4 PM.
  3. Know your skin type and risk of burning. Red hair and very light skin predict a greater risk of burning. (Also remember that dark skin needs more sun exposure to produce vitamin D).
  4. A gradual build-up of a tan protects the skin from burning.
  5. When the skin begins to redden, it is time to stop the sun exposure.
  6. Frequent but shorter sun exposure times are better for producing vitamin D.

Since about 35% of all Canadians do not meet suggested vitamin D requirements, sun exposure is essential to reverse that statistic.

So Canadians, safely enjoy the sun this summer!

A Positive Addiction: More on the Feel-Good Influence of Sun Exposure.

Nearly every article written on the addictive influences of sun exposure or other UV exposure takes a negative tack. We need to realize that some addictions are very good for us. Some runners are addicted to getting up every morning and going on the morning run. If one wants to be slim and fit, that is certainly a positive addiction. Hugging my wife is also a positive addiction; her touch helps to heal me and fills me with an addictive love. I’m also addicted to hiking in the pines and aspens near my Nevada ranch. There is little more exhilarating than being at 11,000 feet elevation and breathing the clear mountain air during a hike. You probably have your own positive addictions.

Sun exposure can certainly become an addiction, but is that all bad? In my opinion, no. When done habitually, sunning reduces the risk of melanoma and reduced the risk of myriad harmful diseases. It is therefore a positive and salubrious addiction.

A recent study, somewhat negative in tone, demonstrates that UVB light, contained in both sun lamp radiation and sun radiation, triggers the production of beta endorphins, one of the feel-good chemicals, sometimes called a “reward” chemical, that makes us want more.[i] The researchers used 12 healthy volunteers and used a UVB lamp to deliver a dose of narrow-band UVB light. Skin samples were taken before and after the exposure. After 24 hours, the skin samples showed an increase in endorphin levels in 11 of the twelve subjects.

Sun exposure enhances health. A twenty-year study demonstrated that the risk of death among people who were sun-seekers was only half that of those who received little sun.[ii] The researchers made this statement: “In both models the summary sun exposure variables showed a ‘dose-dependent’ inverse relation between sun exposure and all-cause death.”

Obviously, habitual sun exposure produces a positive addiction, and that is good! God (or nature if you prefer) has programmed our bodies to seek the sunlight in order to help provide a healthful and rewarding life. “Habitual” is the operative word here. An occasional blast of sun that causes burning is definitely not recommended. Be careful and enjoy your positive addictions.

Sunlight and Prostate Cancer, Part 1.

By Marc Sorenson, EdD, Sunlight Institute

Sunlight exposure is said to cause melanoma, which is false, as we have said many times in this blog. However, other cancers are seldom mentioned by those who would frighten us away from the sun, because the facts don’t fit their agenda. Most major cancers are profoundly reduced by sunlight. Let’s first take the example of prostate cancer (PC) risk, which has been known for at least 15 years to be associated with low sunlight exposure.

Researchers reporting their findings in the British medical journal, Lancet, compared sunlight-exposure history to the risk of contracting the disease, and they found that children who sunburned had about an 82% reduced risk of contracting PC as adults.[1] Of course, no one is recommending sunburn as a preventive measure against prostate cancer. In this case, sunburn served as a surrogate measure for a lot of sunlight exposure. Other measures of sunlight exposure similarly showed protective effects. Regular holidays in warm areas were associated with a 51% reduced risk; a high sunbathing score was associated to a 17% reduced risk, and very low sunlight exposure was associated to a tripling of risk. The researchers stated the following: “These findings are compatible with UVR having a protective role against prostate cancer.”

So why do the anti-sun groups such as the American Academy of Dermatology and the Skin Cancer Foundation mention only skin cancer and neglect to give life-saving information regarding other cancers such as PC? That is an easy answer. Both organizations make big dollars by keeping us in the dark. Follow the money to the sunscreen manufacturers, who have a cozy financial relationship with these supposedly “clean” cancer organizations.

So men, safely sunbathe and get outdoors as much as possible. Your prostate will love you for it.

Dramatic Increases in Melanoma Correlate to Low Annual Sunlight Exposure in Europe.

By Marc Sorenson, EdD, Sunlight Institute

SUNLIGHT EXPOSURE CORRELATES TO A LOWER RISK OF MELANOMA.

I’ve been writing on this FACT for some time, and an impressive 2015 paper corroborates it.[1] Published in the scientific journal Dermato-Endocrinology, the paper makes some very interesting comments, all based on excellent research:
