For millions of Americans, this darkest time of year heralds the beginning of a debilitating mental condition: Seasonal Affective Disorder.

SAD has other symptoms that are more subtle and may not initially seem like a depressive episode. These symptoms include sleep problems, particularly a desire to oversleep and a difficulty of staying awake.

Lethargy and cravings for sweet and starchy foods, irritability, loss of libido and avoiding social contact can all be signs of seasonal depression. According to researchers at the Mayo Clinic, the exact cause of SAD is unknown.

Reduced sunlight during the fall and winter may disrupt the body's circadian rhythm- the internal clock that regulates sleep cycles. Melatonin- a sleep-related hormone that naturally increases during the winter- is also being investigated as a possible cause. And serotonin, one of the primary "brain chemicals" or neurotransmitters affecting mood, has been shown to drop during periods of reduced sunlight.


SAD is most prevalent in areas of higher latitude- farthest from the equator. It commonly begins to develop in young adulthood, and although it is diagnosed more often in women, men may have more severe symptoms

SAD is real. Oftentimes, family members try to "tough it out" or ignore their symptoms, sometimes with disastrous consequences. Sometimes people feel weak or ashamed of their inability to cope. Those experiencing any of the above symptoms, should get a professional diagnosis because serious medical conditions can also underlie feelings of depression.
