Feeling unlike yourself this time of year? You might be experiencing the winter blues—or, for some, a more severe form called Seasonal Affective Disorder (SAD). (Check with your medical provider.) This low mood often begins in Fall and lifts by Summer as sunlight—and serotonin—increase. To beat the winter slump, try using a SAD lamp, exercising, brightening your space, going outdoors more, planning meaningful activities, and keeping a steady sleep routine. Invite someone into this plan and make your spirit bright this coming winter!
