SAD - Seasonal Affective Disorder

Posted Oct 03 2008 12:53pm

Seasonal Affective Disorder (SAD) is depression brought about in certain individuals due to a lack of sunlight.  It has taken awhile for the experts to acknowledge this phenomenon, but SAD is now established.  SAD hits hardest in the winter, and is more common in the North than the South, for obvious reasons.  There is an interesting article discussing SAD and its treatment (including phototherapy, or artifically induced light) at the New York Times Health section.
