Winter officially begins next week. But around here in Boston, I’m already feeling these cold, short, dark days. It’s enough to put you in a bit of a mood.
And it’s not just my imagination, according to psychology researchers Michael Varnum at Arizona State and Ian Hohm at the University of British Columbia. Winter brings seasonal changes that really can mess with your outlook and behavior.
“Some of winter’s effects have been tied to cultural norms and practices,” they write, “while others likely reflect our bodies’ innate biological responses to changing meteorological and ecological conditions.” Depressed mood, an urge to hibernate or eat every holiday treat in sight, a more generous spirit, better concentration, even a heightened sex drive – researchers have documented them all in winter. But teasing out what’s behind these seasonal swings is an ongoing challenge.
