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 description

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.
