The depression lifts in the springtime as the daylight lengthens. SAD is four times more prevalent in women than in men, one German study found. If your doctor diagnoses SAD, light therapy may be recommended. You can use a special light box in your home or office for 30 minutes at 10,000 lux, or one to two hours at 2,500 lux, depending on what light therapy your doctor prescribes. While you're exposed to the light you can work at a desk, exercise on stationary equipment or tackle just about any activity that keeps you reasonably close to the light box.
Many patients see results within a week.
Since SAD may be linked to low serotonin levels, treatment with antidepressants may also be helpful. Inc. All rights reserved.
