Winter is coming. For some that sentence brings a smile to their face as they think of snowfall, holidays, and cozy nights by the fireplace. Others dread the slushy roads, darkness, and frigid temperatures. And for a significant portion of the population, those winter blues get in the way of their everyday functioning, a condition known as seasonal affective disorder (SAD). 

“Five percent of the U.S. adult population suffers from full-blown SAD,” psychiatrist Norman Rosenthal, M.D., shares on this episode of the mindbodygreen podcast. 

Rosenthal was actually the first scientist to describe seasonal affective disorder (and develop light therapy as an effective treatment). He declares the key to combating the winter blues is to prepare during autumn—aka, right about now. 

Below, find some of his top tips to prevent seasonal depression and proactively care for your mental health, no matter the time of year. 

Prepare now for the impending darkness, says Rosenthal. “We don’t realize the extent to which our houses have become dark by winter,” he explains. “The hedges have overgrown the windows and need to be trimmed back, the windows have developed a layer of grime from the summer, which needs to be cleaned off…” Try to introduce more light to your space however you can early on. 

Better yet, “Have at least one room that’s your ‘bright room,’” he shares. Perhaps it has a bunch of windows, and maybe you adorn the walls with a light coat of paint. Rosenthal also recommends investing in extra light fixtures for that room if you don’t have them already. Make designing this room a fun activity you look forward to!  

“Prepare for winter when you don’t need to,” he shares. That’s what it means to prepare, anyway. By making your space ready for the upcoming darkness, it might not feel so bad once it gets there. 

Of course, you can also invest in a sun lamp to help get your natural light fix—browse our favorite options here. 

According to Rosenthal, it’s super common to consolidate your social links during winter. After all, it’s cold, wet, and dark—not the best atmosphere to venture out for social plans. 

But social connections are crucial to well-being! That’s why he encourages you make proactive social plans before winter to take you through the season. “Get your social calendar up and running,” he says. “Say, ‘Listen, I have trouble [making plans] in the winter. If I don’t call you in a week or two, would you just give me a buzz? Or can we have a regular lunch date’” 

If you’re able to take a trip, he also suggests planning ahead your winter vacations. “Book early when the flights are cheaper and get yourself settled and sorted,” he notes. “Prepare when you’re feeling good.”
