Call it the winter blues or blahs or simply seasonal sadness. Whatever term you use, around this time, many of us start to feel our mood sinking. We feel especially tired and sluggish. We might even feel like the walking dead, moping from one task to the next.
That’s because as the days get shorter and colder, we spend more time indoors and are less active, according to Ashley Solomon, PsyD, a clinical psychologist who blogs at Nourishing the Soul. “We tend to be more sedentary, which we know impacts our level of energy and even interest in activities,” she said.
It also doesn’t help that our bodies produce more melatonin when the sun sets, making us sleepy, said Deborah Serani, Psy.D, a clinical psychologist and author of the book Living with Depression. (Interestingly, melatonin is known as “the Dracula of hormones,” because it only comes out at night, according to the National Sleep Foundation.)
