Depression: Foods That Fight Winter Depression (cont.)

Symptoms can range from mild to severe, and people generally recover completely around April or May - once the days become longer.

Treatment includes light therapy and/or medications. However, there are things you can do yourself that can help boost serotonin levels.

3 Ways to Boot up Your Serotonin

Julia Ross, MA, is director of the Recovery Systems Clinic in San Francisco and author of The Mood Cure and The Diet Cure. She tells WebMD there are three ways to jump-start your serotonin:

  • Subject yourself to bright indoor light. This is the touchstone of seasonal affective disorder treatment. Many pricey lights are available. Ross says a 300 watt bulb within three feet for 20 minutes three times a day can help, although the boost in serotonin may be temporary.
  • Exercise. This is very hard to do when caught up in the seasonal affective disorder cycle. But if you can force yourself to start, 15 to 20 minutes of dancing to the radio or fast walking can reduce a sweet tooth and improve mood.
  • Eat wisely. This means, pushing away the leftover cake and eating sensible carbs to stimulate serotonin. Sweets and simple carbs, like white rice and white bread, quickly raise blood sugar, flood you with insulin, and then drop you in a hole. Eating wisely also means watching the caffeine, which suppresses serotonin. "If you must drink coffee, save it for after the meal," Ross says.

More Nutritional Tips for Raising Mood in Winter

Ross also recommends a nutritional supplement called 5HTP (5-hydroxytryptophan), which raises serotonin levels. This is not for everybody -- read the label carefully. For instance, people with heart problems should not take it. Also remember that supplements such as this one are not as closely regulated by the government and may contain questionable substances. Ross says 5HTP should only be taken for a short period, to bump up serotonin levels, which will then stay elevated. "You don't take it forever," she says.

Protein, she says, should be eaten three times a day. Another good rule is to eat four cups of brightly colored veggies a day. "This is enough to fill a (pardon the expression) 1 quart ice cream container." Vegetables are carbs, but the kind that feed into your system slowly.

Samantha Heller, MS, RD, senior clinical nutritionist at the NYU Medical Center, tells WebMD it's best to substitute fruit for cookies and chocolate ice cream. In general, the good carbs of veggies, fruit, and beans help energy levels.

"If weight gain in the winter months is your concern," Heller says, "you should get a healthy eating plan from a registered dietitian."

Timing Is Also Everything

It's fashionable to urge people to eat half a dozen small meals a day, but this is an individual preference, Heller says.
