Insomnia-a common and difficult-to-treat condition-is estimated to cost the American economy $63.2 billion each year in lost productivity. A new body of research suggests that a cure might be as simple as soaking up some sun.
Blue light, a part of the visitble spectrum in solar rays, keeps us perky during th day, by suppresing the release of melatonin, the hormone that causes sleepiness. But when we spend our time cooped up indoors, our eyes fail to take in the proper amount of light, and we never get an internal signal to sleep at night.

-Take your lunch outside or walk to sowrk, when the sun is at its brightes
-Read a book before bedrtime rather than watching TV. The light might turn off your melatonin and impede sleep.
-Take off your sunglasses, at least for awhile during the day to get that blue light
