If you are depressed during the shorter days of winter, and happier during the longer days of summer...you may have seasonal affective disorder.
Symptoms begin and around the same time each year...usually starting in September and ending in April.
People become more irritable, sad, anxious, they eat more, and are drowsy during the day.
Treatment for SAD includes light therapy, in which you sit a certain distance from artificial bright lights...usually in the morning.
Therapists say some people may require professional help.
