Just "D" Facts about Vitamin D

Benefits of Moderate UV Sunshine Exposure

Health Care, Vitamin D, and Indoor Tanning

It is a shame that this Congress is doing everything backwards. moderate and controlled non-burning exposure to Sunshine would reduce Health Care costs, not add to it.

Vitamin D is produced in Human skin when exposed to UV rays, whether they come from the sun or an indoor sunbed.

There are millions of Americans who get burned, literally, from casual outdoor exposure on a daily basis. a recent study shows that up to 36% of US burn every year. There are no “Sunburn Police” at the local pools or beaches all summer, but every day you can see numbers of “Lobster Red” people after a day outside.


The studies that make headlines recently do not bother to delve deeper into the numbers to see that those that work outdoors, or spend regular time outside actually reduce their risk for melanoma, a skin cancer mainly in Males and indoor workers.

People that use sunbeds are shown to have 90% higher levels of Vitamin D, 18% lowered PTH levels, and higher Bone density than those who do not.


The actual numbers in melanoma are infinitesimal in relation to the bigger picture from under exposure to Nature’s own “Sunshine Vitamin” The health consequences of NOT having high Vitamin D levels can be up to measured in BILLIONS of DALY’s vs Millions from even today’s exposure levels.

UVR exposure is a minor contributor to the world’s disease burden, causing an estimated annual loss of 1.6 million DALYs; i.e. 0.1% of the total global disease burden. A markedly larger annual disease burden, 3.3 billion DALYs, might result from reduction in global UVR exposure to very low levels.


Melanoma Mortality Rates have remained steady for Women for the past 30 years at a rate of 2/100,000 while Men have risen two-threefold in the same time frame. Women frequent tanning salons at a ratio of 4:1, shouldn’t the rate be reversed?


In the most recent headline, the media neglected to see past the flash and see the study showed Lifetime routine exposure, outdoor activities, and outdoor jobs actually lowered the risk of melanoma, while use of chemical sunscreens raised the risks.

What stood out in this report was the fact that those with many moles the risk was raised 1,281%, having very fair skin raised the risk 450%, and Red hair raised the risks 253%. These are all characteristics of a Skin Type 1 which would not and should not look for additional sun exposure, indoors or outside.


Humans evolved under the sun. Mother Nature played a cruel joke in that the same UVB that produces vast amounts of Vitamin D in the skin can also burn and/or damage it with overexposure. Sunscreens have been in use for the past 40 years, and not surprisingly, by blocking Natures’ own protection, we may have caused many of the melanomas being seen.


Interestingly, the same sun that may cause melanoma may actually protect against the most serious cases.

A little bit of anything is usually good for us, but an overabundance may cause harm. Moderation is the key. Get regular sun exposure on as much body surface for a short period of time outdoors when you can, between the hours of 10A and 2P, when the sun is above 45°, typically between April and November at a line from Boston to Sacramento (40°N Lat).

If that’s not practical, Indoor tanning salons offer time controlled UV exposure that doesn’t vary with the time of day, season, cloud cover, ozone layer, or many other factors.
