  • Didgeridoos and didgeridon'ts

    Being interested in music - I don't play an instrument but do sing in a choir - I was interested in the reports that playing the didgeridoo could help with OSA - and wondered if this was an urban myth.

    From what I can gather this is based upon research carried out in Switzerland in 2005 and published in the British Medical Journal of Dec. (Dr Milo Pulan et al) Here is the link for those who wish to read the study:

    Objective To assess the effects of didgeridoo playing on daytime sleepiness and other outcomes related to sleep by reducing collapsibility of the upper airways in patients with moderate obstructive sleep apnoea syndrome and snoring. Design Randomised controlled trial. Setting Private practice of a didgeridoo instructor and a single centre for sleep medicine. Participants 25 patients aged > 18 years with an apnoea-hypopnoea index between 15 and 30 and who complained about snoring. Interventions Didgeridoo lessons and daily practice at home with standardised instruments for four months. Participants in the control group remained on the waiting list for lessons. Main outcome measure Daytime sleepiness (Epworth scale from 0 (no daytime sleepiness) to 24), sleep quality (Pittsburgh quality of sleep index from 0 (excellent sleep quality) to 21), partner rating of sleep disturbance (visual analogue scale from 0 (not disturbed) to 10), apnoea-hypopnoea index, and health related quality of life (SF-36). Results Participants in the didgeridoo group practised an average of 5.9 days a week (SD 0.86) for 25.3 minutes (SD 3.4). Compared with the control group in the didgeridoo group daytime sleepiness (difference &#8722;3.0, 95% confidence interval &#8722;5.7 to &#8722;0.3, P = 0.03) and apnoea-hypopnoea index (difference &#8722;6.2, &#8722;12.3 to &#8722;0.1, P = 0.05) improved significantly and partners reported less sleep disturbance (difference &#8722;2.8, &#8722;4.7 to &#8722;0.9, P < 0.01). There was no effect on the quality of sleep (difference &#8722;0.7, &#8722;2.1 to 0.6, P = 0.27). The combined analysis of sleep related outcomes showed a moderate to large effect of didgeridoo playing (difference between summary z scores &#8722;0.78 SD units, &#8722;1.27 to &#8722;0.28, P < 0.01). Changes in health related quality of life did not differ between groups. Conclusion Regular didgeridoo playing is an effective treatment alternative well accepted by patients with moderate obstructive sleep apnoea syndrome. Trial registration ISRCTN: 31571714.


    This makes interesting reading and the conclusions that "proof of concept" was established seem pretty sound, but as the authors say the research needs following up with larger scale studies (Only 25 subjects split into two groups in this study) and with more diverse populations. I can't find any follow up studies at the moment and think this is a pity. Apparently there are similarities in playing the didgeridoo to the breath control required to play the Tuba and Trombone. So it would be interesting to see if brass band players suffered less OSA than the general population! A fruitful area for further research.

    The physiological reasons are a bit beyond me - I have read a bit about circular breathing - Kenny G does it on his saxophone - and can apparently maintain a note without stopping for long periods of time - by simultaneously breathing in through the nose while blowing out through the mouth!

    So are there are any tuba or trombone players on this forum who suffer from OSA?

    If you want a critique of the findings follow the Rapid Responses on the link - where there is a reply from a Tuba player and some other interesting points.

      I guess it works similar to the singing for snorers concept. Toning the muscles in that area can hardly make things worse, so it seems quite logically it may be of benefit. Whether ot not it will cure a severe apnoeic remains to be seen but it wouldn't hurt to try if OSA is only mild and one doesn't fancy CPAP or any other standard method just yet.
