NASHVILLE –Based on national estimates, thousands of Tennesseans struggle through the cold and dreary winter season with feelings of prolonged sadness. For an estimated 4 to 6 percent of the population, winter brings about periods of fatigue and in some cases anxiety known as Seasonal Affective Disorder or (SAD).
The Tennessee Department of Mental Health and Substance Abuse Services (TDMHSAS) recognizes SAD as a mood disorder that follows a pattern related to seasonal variations in sunlight.
“We all go through periods of feeling down,” said E. Douglas Varney, Commissioner TDMHSAS. “SAD is something more serious than the occasional blues and can lead some people into periods of deep depression due in part to fewer hours of daylight in the winter months.”
