Summary
This study tests whether using a bright light box for six weeks can improve mood and sleep in people with bipolar depression who naturally feel more alert in the evening. About 70 adults aged 18-65 will either receive the light therapy or a placebo light. The goal is to see if this simple, drug-free approach can reduce depressive symptoms and insomnia.
