The UPside of UV rays

The Deluxe Light Visors we at BioBrite sell are UV free, meaning that you will not be overexposed to UV rays when getting your dose of energy during the SAD months. But, like everything, it turns out there is a downside to UV free. ("UV" means Ultra Violet, a part of the light spectrum that humans cannot see.)

The UV rays are the rays that we filter out in our light appliances are the UV rays that work with your skin to create Vitamin D. Sufficient Vitamin D, a new study at the Creighton University School of Medicine indicates, as reported in the media on 8 June 2007, shows that people with sufficient Vitamin D are 60% less likely to come down with any kind of cancer.

(The study was on 1,200 adult women and is not considered conclusive because of its relatively small size. But the reduction of cancer among those studied was clear.)

Thus, in the grey winter months, when the sun don't shine, it may do you well to take a Vitamin D supplement. The authors of the Creighton study suggest a 1,000 IU's during the winter.

Talk to your health care provider before buying Vitamin D supplements. If you decide to, the tall guy next in line might be me. Say hi.
