But "exercise can boost your mood, and you need that lift even more during the winter," says Patricia Laguna, PhD, a professor of kinesiology at California State University, Fullerton.

Laguna suggests that you give yourself some incentive. Jot down an exercise schedule at the beginning of the week, varying the type of sweat fest to keep it interesting; then reward yourself with a small treat, like a mani-pedi, when you stick to it. And consider braving the elements: Research shows that exercising outside can lift your spirits, but if the weather won't cooperate, keep a go-to exercise DVD on hand.

10 Winter Health Myths

Highly refined carbs and sugar can wreak havoc on your blood sugar level, which can leave you feeling cranky, says Elizabeth Somer, RD, author of Eat Your Way to Happiness. Some comfort foods, however, can double as healthy pick-me-ups, especially if they contain mood-boosting nutrients like omega-3 fatty acids, good carbohydrates (think whole grains and vegetables), protein, and B vitamins.

Sommers suggests oatmeal for breakfast, because it contains fiber-rich whole grains that increase serotonin, a feel-good chemical in your brain, and it steadies your blood sugar level. For dinner, toss omega-3-rich salmon with whole-wheat pasta.

Instead of holing up in your house until spring, set aside some time each day for a "buddy moment," whether that's grabbing a quick lunch with a co-worker or meeting your sister for a Spinning class. Establishing "get together" routines also helps, Sternberg adds: Start a wine-tasting club, or invite friends over for a dance-workout party.

But staying warm is a surprising secret to feeling merry. "Winter's cold can make you feel sluggish because of the increased energy demand on your body," says Vincent Pedre, MD, a clinical instructor of medicine at Mt. Sinai Medical Center in New York City.

But in the winter, the sun's rays aren't strong enough in the northern half of the United States to power D production. Ask your doc for a simple blood test to see if you're deficient, and talk to her about taking a supplement if you are.

Beyond the D factor, sunlight increases levels of serotonin and also works to suppress melatonin, a chemical that makes you drowsy, explains Norman Rosenthal, MD, author of Winter Blues. To get your fill, consider investing in a light box, which can help combat sluggishness. And be sure to pop outside whenever you do spot some rays.
