Exercise, of course. A current TIME.com slide show article listed exercise as one of 8 ways to ward off the “Winter Blues.” Michael Terman, director of the Center for Light Treatment and Biological Rhythms at Columbia University Medical Center, noted that around 33% of patients who practiced regular aerobic exercise showed a “marked lift in depressed mood,” but only if they kept at it! The good news is that socializing also made the list, so grab a friend, hit the gym, and really fight the “winter blues.”
