Study Summary
We are offering non-pharmacologic therapy for alleviation of symptoms associated with depressed mood that recurs annually in fall or winter. The treatments are self-administered at home by the patient, with close clinical supervision. Our trials use specially designed devices that replenish two different environmental elements, naturally occurring light and negative ions in the air. Both factors may be reduced in winter, bringing on depression.
Primary Outcome
reduction from depressed baseline
Interventions
- DEVICE bright light box
- DEVICE dawn simulator
- DEVICE high-output negative ion generator
- DEVICE low-output negative ion generator
- DEVICE dawn light pulse
