Vitamin D, otherwise known as "the sunshine vitamin," is produced through direct exposure to sunlight, and it's one of the most important vitamins we humans need. Vitamin D's main role is to help the body utilize calcium and to keep our bones and teeth strong. You know, all that "bone density" stuff.
But we're not getting enough sun now that we're dwelling indoors from dawn until dusk in front of computer and teevee screens. It doesn't matter whether we're job seekers, employees, or teenagers, either. In fact, it was recently estimated that more than three-fourths (77%) of Americans have low Vitamin D levels without knowing it. That's a lot of lethargy.
Low Vitamin D levels are having a big impact on the workplace, too. Consider a February 2012 observational study of 10,646 employees of a Midwestern-integrated health care system that found Low vitamin D levels were leading to lower employee productivity levels, and that simple treatment of the condition translated into overall productivity savings. Cha-Ching!
It's something to think about as we bathe ourselves in fluorescent lighting, wonder why our fingernails keep breaking, and watch that sun-kissed rollerblader pass by our window again. The good news? Vitamin D deficiency is easily treatable in most people. But I'm definitely not a doctor and no one would ever want me to be one, and so I'll leave further information about symptoms and treatment to the experts. Enjoy the summer!
