Snoring and obstructive sleep apnea syndrome are two highly prevalent sleep disorders caused by collapse of the upper airways. The most effective intervention for these disorders is continuous positive airway pressure therapy, which reduces daytime sleepiness and the risk of cardiovascular morbidity and mortality in the most severely affected patients. For moderately affected patients who complain about snoring and daytime sleepiness, however, continuous positive airway pressure therapy may not be suitable, and other effective interventions are needed.
A didjeridu instructor noticed that he and some of his students experienced reduced daytime sleepiness and snoring after practicing with this instrument for several months. A randomized controlled experiment confirmed that regular didjeridu playing is an effective treatment alternative well accepted by patients with moderate obstructive sleep apnea syndrome.
This according to “Didgeridoo playing as alternative treatment for obstructive sleep apnoea syndrome: Randomised controlled trial” by Milo A. Puhan, et al. (BMJ CCCXXXII [December 2006]; RILM Abstracts of Music Literature 2006-51373). The article won the Ig Nobel Peace Prize in 2017.
