We've all heard of alternate treatments to CPAP use, the gold standard for the treatment of Obstructive Sleep Apnea, but most have no scientific validation and many are no more than "snake oil" treatments. In 2006, though, a Swiss study studied the effects of playing the didgeridoo, an instrument played commonly by Australia's Aborigines, on mild to moderate Obstructive Sleep Apnea. Surprisingly, the study found that playing the didgeridoo regularly can treat up to moderate Obstructive Sleep Apnea effectively. The theory is that playing the didgeridoo, an instrument that requires a complex pattern of respiration called "circular breathing", strengthens the muscles of the mouth and throat, preventing the soft palate collapse that characterizes an obstructive apnea or hypopnea.
See more about the study and about playing the didgeridoo on About.com. And while we would never recommend discontinuing your (possibly life-saving) CPAP usage, this could be a fun therapy to try in conjunction with your current treatment program. Now, where to find a didgeridoo teacher??
