A breathing trial measures sleep experience, not airway recovery
Renewed reporting on a small pranayama trial calls for a careful distinction between symptom scores and sleep-apnoea severity.
Coverage on 30 October has returned to a trial first published on 16 April in BioPsychoSocial Medicine. Researchers at Istanbul University-Cerrahpasa randomly assigned 38 adults with mild to moderate obstructive sleep apnoea to home-based pranayama or no intervention. Thirty-four completed the study.
A small study with a specific outcome
Participants practised three breathing techniques for 15 minutes, three times daily, over eight weeks, with additional physiotherapist-supervised video sessions three days a week. Self-reported sleep quality improved more in the intervention group, alongside several other questionnaire outcomes.
The study was open-label, and the control group received no comparable attention. Importantly, researchers did not repeat the apnoea-hypopnoea measurement after training. Better symptom scores therefore cannot establish that breathing interruptions during sleep improved. The result supports further research into an adjunct approach; it does not justify replacing prescribed sleep-apnoea treatment or presenting a general breathing class as equivalent to the studied programme.
