Since the Industrial Revolution, we’ve known about Rickets and other diseases and problems caused by the lack of sunlight as we as a people moved indoors. The lack of Calcium may also lead to Ricketsand other bone problems. I leave it to the diet bloggers to discuss the lack of Calcium in our diet, perhaps because of too many soft drinks and not enough milk.
Here’s a link to an article on Vitamin D Deficiency that you might want to read.
Research has shown that it is the UV (Ultraviolet) portion of the spectrum that helps the body create Vitamin D . This is one of the known benefits of UV. The use of sun-screens, hiding indoors from the sun as we worry about skin cancers and the like is now perhaps one of the causes of Vitamin D deficiencies in some of our population.
Dr. Michael F. Holick, author of The UV Advantage is one of the world’s experts on Vitamin D runs a website/blog called www.VitaminDHealth.org. I met Dr. Holick at Boston University many years ago along with Jim Shepherd of KBD. Jim and I were looking into the marketability of a product that Jim’s company now makes. This is a Vitamin D UV Lamp. It is not being sold as a medical device and from what I see on his website there is no FDA approval (for Vitamin D) on the device(s) that KBD (Sperti) is selling. I am making you aware of this product only, I do not recommend its use. Please check our DISCLAIMER page on this blog.
There are many sites that recommend exposure to UV light to help with Vitamin D production in our bodies. The problem that I see is that there are no guidelines as to which wavelength(s) of UV are most effective, what energy levels are recommended or treatment/dosage times. This leads to anarchy in the field. Some are recommending UVA, some UVB but none that I see give treatment guidelines.
Our firm (www.amjo.net and www.HomePhotoTherapy.com) has avoided offering UV products for Vitamin D production as there are no clear treatment guidlines. I personally recommend that you buy a sports car, drive top down for fun in the sun. This seems to work for me.
