The treatment involves playing a didgeridoo.
"Researchers reporting in the British Medical Journal evaluated 25 people with sleep apnea--a breath-stealing condition caused by flabby throat muscles--and found that those who took 4 months of didgeridoo (DIH-jeh-ree-doo) lessons had about 3 1/2 times less daytime sleepiness than the folks who didn't blow their own horns. The newly minted musicians also snored significantly less." (Men's Health)"Sounds" like a potentially fun treatment.
The full results of the study are available here on the British Medical Journal website with further commentary by Scientific Daily here.
The study concludes that didgeridoo playing on a regular basis is an effective alternative treatment for those with moderate obstructive sleep apnoea syndrome.
I wonder if it would help severe sleep apnea sufferers. If playing the didgeridoo regularly could move severe sleep apnea into mild sleep apnea, that would be a really good thing.
Then again, have you ever heard the sound a didgeridoo makes? There's an example of a street performer playing a didgeridoo in Barcelona, Spain here.
