Abstract:
Studies have shown that depressed patients with seasonal affective disorder (SAD) respond to treatment with bright artificial light. In this study 2 hours of bright artificial light administered in the morning for 1 week did not alter mood in 11 normal subjects. This finding suggests that the mood-enhancing effect of light for SAD patients is not necessarily generalizable to other populations.
