The “other” ABC is reporting on a study showing that taking up the Didgeridoo leads to better sleep, and less snoring. The clinical test was performed after instructors noted that students “spontaneously” reported better sleep. After 4 months, didgeridoo learners who practiced 20 minutes a day had better sleep, and less daytime sleepiness.
It’s an interesting result. The article suggests it is the result of learning to “circle breath” but I suspect it has as much to do with the meditative nature of playing any instrument, but especially one that requires attention to the breath.
