Could Indoor UV Light Be a Surrogate for What Nature Intended?

Sun vs UV

Vitamin D production is one of the benefits that has been associated with human exposure to ultraviolet-B (UVB) emitted in sunlight and by an estimated 90 percent of commercial indoor tanning equipment. While the North American indoor tanning industry conducts indoor tanning as a cosmetic service, an undeniable physiological side effect of this service is that indoor tanning clients manufacture sufficient levels of vitamin D as a result of indoor tanning sessions.

  1. Vitamin D is a hormone produced naturally when skin is exposed to UVB in sunlight or indoor tanning units. Scientists through thousands of studies now recommend vitamin D blood levels of 40-60 ng/ml.
  2. Vitamin D sufficiency is linked to a reduction in 105 diseases, including heart disease, diabetes, multiple sclerosis and most forms of cancer. It is believed that vitamin D deficiency contributes to nearly 400,000 premature deaths and adds a $100 billion burden to our health care system.
  3. 77 percent of Americans are considered vitamin D deficient according to government data and overzealous sun avoidance is the only plausible explanation for the 50 percent increase in that figure in the past 15 years
