Those affected by seasonal affective disorder (SAD) need daylight desperately with morning light doing them the most good. SAD affects its victims during the colder months of the year with January and February bearing the brunt. Just as spring appears, prolonging the daylight and ushering in earlier daybreaks, daylight savings time throws on the breaks. At best, it is disconcerting for a week or two. SAD symptoms include fatigue, no interest in socializing or in social activities, weight gain and a craving for foods high in carbohydrates. More light is the standard solution prescription for SAD. Most doctors prescribe patients to get a therapeutic light box and sit close to it for at least 20 minutes a day.
