" Dark, chilly days may be the culprit for an ailment besides seasonal affective disorder: back pain. Since the winter sun is too far for UVB rays to significantly reach most of the Northern Hemisphere, we don&amp;#039;t end up making enough vitamin D, which helps maintain strong bones for healthy backs. Stewart B. Leavitt, Ph.D., executive director of Pain Treatment Topics, reports that back-pain sufferers given 2000 IU of vitamin D3 supplements\u2014double the typical RDA\u2014may feel relief after three months.
