For all its holidays and celebrations, winter can be a tough time for many people. The long nights and cold, gray days can knock us off our regular routines and just leave us feeling a bit down. And that’s to be expected from time to time. For some people, though, the changes in mood they experience in winter can be more severe and lasting, pointing to a serious condition called seasonal affective disorder.
Seasonal affective disorder, or SAD, is an illness that is tied to other mood disorders, such a depression and bipolar disorder, and it can significantly impair daily living. As the name implies, it has a clear pattern of coming on and then going away during specific seasons. “The most common form of seasonal affective disorder is major depressive disorder with a major depressive episode in winter,” said Dr. Emily Mukherji, adult psychiatry clinic director at Washington University School of Medicine in St. Louis.
About 1-3 percent of people in the U.S. will at some point experience an episode of seasonal affective disorder. Typical symptoms for the condition most often mimic those for depression, including decreased mood, lack of interest or pleasure in activities, difficulty concentrating or thoughts of suicide. Some symptoms, though, can be more specific to seasonal affective disorder, such as lower energy levels, an increased appetite with carbohydrate cravings and an increased need for sleep.
“It’s almost like a form of hibernation in the winter months,“ Mukherji said.
The good news, though, is that seasonal affective disorder can be treated. So, it’s important to talk to a health-care provider if you’re concerned about how you’re feeling. The worse you feel and the worse your symptoms, the more imperative it is to get help. “Anyone at imminent risk of hurting themselves or others should call 911 and go to an emergency room right away,“ said Mukherji.
Treatment for seasonal affective disorder most often involves a combination of antidepressant medication and light therapy, which is the use of a special lamp that simulates exposure to sunlight. Someone with only mild symptoms may use light therapy on its own, without medication.
Light therapy lamps are available online and at specialty stores and can cost around $30 and up. Some provide continuous bright light that you can sit in front of while reading, eating breakfast or watching your favorite show. Others act more like a natural alarm clock, simulating the light of the rising sun over a 90-minute period or so.
