Vitamin D in Canada and Ely, A Vitamin D Society warning

 

vitamin D from lightVitamin D is essential in Canada (and Ely). By Marc Sorenson, EdD.

I just received an excellent press release from my friend Perry Holman, who is touting the Canadian Vitamin D Day. Perry is the Executive Director of the Vitamin D Society. The Society is alarmed about the lack of sunlight and vitamin D production during the long Canadian winter. The points made in the press release, however, are also relevant for all areas of the U.S. that have long, cold winters.  This would include Ely, Nevada, my high-school hangout. Therefore, this blog contains a couple of editorial comments regarding Ely and other points in the U.S. [Ely, Minnesota would certainly need this advice too.]

The current lack of vitamin D is due to of the position of the sun in the winter sky. All of the UVB light that stimulates vitamin D production (and many other essential photoproducts) is filtered out when the sun drops too close to the southern horizon.

Here are a few of the salient points made in the release:

  • Vitamin D levels plummet this time of year, since the sun can no longer make vitamin D. [This is also true of Ely, NV, where most vitamin D production ceases on about October 1. It starts up again about March 1.]
  • 93% of Canadians are vitamin D deficient. [For Ely, the number is probably closer to 50%, but for the Northern states in the U.S., the number is probably closer to 80%.
  • This deficiency leads to 23,000 premature deaths yearly in Canada. See this link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5129897/pdf/kder-08-01-1248324.pdf
  • There are two primary sources of vitamin D Canadians should consider during the winter – artificial UVB exposure and vitamin D3 supplements.
  • Artificial UVB exposure can be a surrogate for summer sunshine and is obtained from most sunbeds or through special UVB lamps designed for home use.
  • A recent Canadian study found that regular use of sunbeds with UVB similar to outdoor summer sun significantly raised participants’ vitamin D levels to the optimal range. See this link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5821157/
  • Perry Holman states: “The current health policy limiting sun exposure may be causing more deaths and disease than its preventing. Vitamin D levels have been dropping and more people are becoming vitamin D deficient in Canada. We need a change in direction to encourage people to get moderate non-burning sun exposure to prevent vitamin D deficiency and reduce the risk of serious diseases.” [My comment here is that the research in my book shows the following: for every single death caused by diseases associated with sun exposure, there are approximately 328 deaths caused by diseases associated with sun deprivation.]

Whether you live in Canada, Ely, Nevada, or anywhere else where you either avoid the sun or have no availability of vitamin D-producing sunlight during the colder seasons, you should read this press release. http://www.vitamindsociety.org/press_release.php?id=59

Happy sunning, and as another of my Canadian friends says, “Have a D-lightful day!” And, read my new book, Embrace the Sun, available at Amazon: https://www.amazon.com/Embrace-Sun-Marc-B-Sorenson/dp/069207600X/ref=sr_1_1?ie=UTF8&qid=1540903899&sr=8-1&keywords=embrace+the+sun+sorenson
