Winter depression not as common as many think

New research suggests that getting depressed when it's cold and dreary outside may not be as common as is often believed.

"We found a very small effect during the winter months, but it was much more modest than would be expected if seasonal depression were as common as many people think it is," said Columbia University researcher Jeff Shaman, a study co-author and a former OSU faculty member. "We were surprised. With a sample of nearly 800 people and very precise measures of the weather, we expected to see a larger effect."

Kerr believes the public may have overestimated the power of the winter blues for a few reasons. These may include awareness of SAD, the high prevalence of depression in general, and a legitimate dislike of winter weather.

"We may not have as much fun, we can feel cooped up and we may be less active in the winter," Kerr said. "But that's not the same as long-lasting sadness, hopelessness, and problems with appetite and sleep -- real signs of a clinical depression."
