Ah, winter: the time of the year when dark, cold — or, SAD.

While SAD can strike you from the American Academy of Family Physicians found that a disproportionate number of women suffer from the disorder. Dorothy Sit, an associate professor of psychiatry and behavioral Sciences at Northwestern University, told the Cut that the disorder likely has to do with the disruption of your circadian rhythm in the winter.

Aside from clinical methods of therapy, one common treatment for SAD is bright light therapy, which involves sitting or working near a light therapy box that gives off a recommended 10,000 LUX. A 2017 study published in The Journal of Nervous and Mental Disease found that after just a single one-hour light therapy session, subjects had “a modest improvement of SAD depression symptoms.” Per Sit’s recommendation, the best way to reap the benefits of light therapy is to sit in front of a SAD lamp for approximately 30 minutes, ideally soon after awakening.

“By implementing bright light therapy in patients’ routines, the idea is that we may be able to reset their circadian rhythm, which may have gotten pushed back more than usual due to light signals,” she told the Cut. “Some people will develop a rapid response, and they can get significantly better in just two to three weeks.”

Even if you don’t have SAD, most peoples’ circadian rhythm gets off in the winter and sitting in front of a SAD lamp can only help. Just be careful if you do have a history of clinical depression or bipolar disorder — psychologists say the lamps can interact with medication or create an exaggerated response, so it’s best for anyone with these conditions to consult with a medical professional first.
