"I’’d get depressed and gain 10 pounds every winter and lose them again in the spring." Then she read about seasonal affective disorder, a form of depression that occurs in fall and winter, and she saw the light -- literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking it’’s still enjoying those long summer days. It seems to work. Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and 25 million more develop milder versions.
