alt Hacker NewsI started playing didgeridoo 10 years ago for precisely this reason. Sleep apnea already cured by weight loss, but I knew by air pathways were prone to it, and I never wanted it to come back.
It worked
It took me 1-2 years to learn circular breathing, but even just learning to play for 15 seconds on one breath can give the "oxygen high" from breathing so much.
You can't get "oxygen high" from breathing normal air. The O2 levels will always stay the same unless you stop breathing for a while. What will make you feel weird in the head when breathing too fast is the reduction of CO2 in your blood.
