As soon as the clocks change each fall, do you feel like your body goes into hibernation mode?
When winter mood shifts bring us to the point of depression, the experience is called Seasonal Affective Disorder, also known as S.A.D., and the mental health effects can be devastating for some people.
Kathryn Roecklein, Assistant professor in the University of Pittsburgh Department of Psychology and Center for the Neural Basis of Cognition at Pitt and CMU studies and treats S.A.D.
She says, contrary to what some people think, S.A.D. is not a response to cold weather, but the shorter days of winter and lack of sunlight.
