Most of us have experienced some degree of winter blues, and as many as 10 million Americans suffer a more severe form of the seasonal depression now known as Seasonal Affective Disorder (SAD). The predominant theory as to the cause of SAD is absence of sunlight during the winter months, which causes hormonal imbalances, in particular an excess of the pineal secretion, melatonin. Although there is no definitive test for SAD, most SAD patients have high levels of melatonin in their blood. About 75% of SAD sufferers are women, which confirms a link to hormonal fluctuations.
