If there's any truth to the old saw that "misery loves company," Minnesota has been the epicenter of camaraderie this winter.
The one-two punch of the snowiest February on record and below-zero temperatures in March left many Minnesotans reeling. Even members of the flannel-wearing, snowblowing-fanatical, "we love to brag about our nasty weather" contingent started to look skyward and whine, "When is it gonna end?"
The winter blues are a common experience, and even if it was a little worse than usual this year, mental health professionals have suggestions for combating it.
"Usually about 20, 25 percent of the general population will experience some subtle changes in their mood, where they may become just a little bit more apathetic, maybe just a little bit more down," said Craig Sawchuk, a professor of psychology with the Mayo Clinic. "I think one of the best ways of describing the symptom pattern is it's actually like hibernation."
Referred to as seasonal affective disorder (commonly called SAD) or seasonal depression, the symptoms include disruptions in sleep, such as hypersomnia, cravings for carbohydrates and mood changes. It's believed that the main causes are the low temperatures and lack of sunlight.
"Seasonal depression is a recurrent depression that comes on in the fall and winter and tends to resolve by spring," said Dr. Barry Rittberg, a psychiatrist with the University of Minnesota Health.
Some physicians prescribe therapeutic light boxes to their patients to help counter these winter blues, as Rittberg has been doing for over a decade. You don't need a prescription to buy one, but having the script will enable some health insurance plans to pick up the cost.
Rittberg recommends a light box rated at 10,000 lux, a measure of brightness, and keeping it at least 18 inches away during the treatment.
