Official Title: 30-Minute Light Exposure for the Treatment of Seasonal Affective Disorder
Brief Summary: The primary objective of this study is to evaluate the effect of light therapy using a narrow 467nm light compared to a 580nm light in subjects with Seasonal Affective Disorder (SAD). It is hypothesized that the 467nm light will improve the symptoms of SAD better than the 580nm light.
Detailed Summary: Participants will be randomly assigned to receive either a 467nm light or a 580nm light. Participants will use the light every day for six weeks for 30 minutes. Multiple assessments and questionnaires will be given weekly to assess the efficacy of the treatment.
