Bulimia is a troubling eating disorder in which patients eat unusually large amounts of food within a short space of time ('binging'), ofter followed by purging, fasting or excessive exercise.
Often, this occurs in private, with even close family members unaware. Bulimia is often accompanied by depression, which can be season - related.
In a pioneering controlled clinical study, Dr. Ray Lam at University of British Columbia (Vancouver) showed that within 2 weeks of treatment, using a 10,000 lux lightbox, bright light therapy, for 30 minutes a day significantly reduced binging and purging, while the winter depression lifted.
After 4 weeks of treatment, binging reduced by 50% and purging by 42%.
