Autumn brings a dramatic reduction in the amount and intensity of natural sunlight.
Over nearly two decades, light treatment with a portable lightbox has come to be recognized as the most effective and least expensive way to treat this problem. Light has also been demonstrated to be effective for treating many sleep problems, jet lag, shift-work adjustment, and the agitation that often accompanies Alzheimer's disease. There is also solid research demonstrating the effectiveness of light treatment for people suffering from premenstrual disorders, attention problems, and alcoholism. A lightbox should be used daily for 15-30 minutes, generally in the morning, throughout the period of time that the user is usually symptomatic. You simply sit in front of a lightbox while reading or eating, allowing your eyes to be exposed to the light without staring at it.
