TL;DR
A 2006 randomized trial showed that didgeridoo playing significantly decreased daytime sleepiness and sleep apnea severity in patients with moderate obstructive sleep apnoea. The study suggests a potential non-invasive treatment alternative.
A 2006 clinical trial found that regular didgeridoo playing significantly reduced daytime sleepiness and the severity of sleep apnea in patients with moderate obstructive sleep apnoea, suggesting a potential non-invasive treatment alternative.
The study involved 25 adult patients with an apnoea-hypopnoea index between 15 and 30, who practiced didgeridoo for about 25 minutes, five days a week, over four months. Results showed a significant decrease in daytime sleepiness, with an average reduction of 3 points on the Epworth scale, and a reduction of approximately 6.2 in the apnea-hypopnoea index. Partners also reported less sleep disturbance. The control group, which did not practice didgeridoo, showed no such improvements.
Participants in the intervention group learned techniques such as circular breathing and lip vibration, which are believed to strengthen upper airway muscles. The study reported no significant change in sleep quality or health-related quality of life measures. The findings were published with the trial registration number ISRCTN: 31571714.
Why It Matters
This research indicates that didgeridoo playing may serve as a non-invasive, well-accepted alternative treatment for patients with moderate obstructive sleep apnoea, especially for those who cannot tolerate continuous positive airway pressure therapy. If confirmed by further studies, it could expand treatment options and reduce reliance on device-based therapies.

Background
Obstructive sleep apnoea is caused by airway collapse during sleep, leading to snoring, daytime sleepiness, and increased cardiovascular risk. Standard treatment, continuous positive airway pressure (CPAP), is effective but often poorly tolerated. Prior anecdotal reports suggested that didgeridoo playing might strengthen upper airway muscles, but robust clinical evidence was lacking until this 2006 trial. The study was conducted at a sleep medicine center in Switzerland, with participants recruited from local clinics.

What Remains Unclear
While results are promising, the study involved a small sample size and was conducted over four months. Long-term effectiveness, optimal training protocols, and applicability to broader populations remain unconfirmed. Further randomized controlled trials are needed to validate these findings and determine if didgeridoo can be widely recommended as a standard treatment.

What’s Next
Future research should focus on larger, multicenter trials with longer follow-up periods to verify the durability of benefits. Studies comparing didgeridoo training directly with established treatments like CPAP are also needed. Clinicians and patients await more definitive evidence before adopting this approach broadly.

Key Questions
Can playing the didgeridoo cure sleep apnoea?
Current evidence suggests it can reduce symptoms in some patients with moderate obstructive sleep apnoea, but it is not yet confirmed as a cure. More research is needed.
How often and how long must one practice to see benefits?
The study participants practiced about 25 minutes, five days a week, over four months. Consistency appears important for potential benefits.
Is didgeridoo playing safe for everyone?
Generally, yes, but individuals with certain respiratory or oral health issues should consult a healthcare provider before starting training.
How does didgeridoo training compare to other treatments?
It appears promising as a supplementary or alternative approach, especially for those intolerant to CPAP, but direct comparisons are lacking.
