What the Study Found (In Plain English)
Published in Journal of sleep research (2024), this meta-analysis evaluating human clinical outcomes investigated: Obstructive sleep apnea is the most common sleep disorder. Key clinical takeaway: Regarding expiratory muscle training, it may improve expiratory muscle strength and sleep quality, but not sleepiness when compared with sham. The evidence on the effects of expiratory muscle training in apnea-hypopnea index is very uncertain.

Study Limitations & Caveats Before You Act
Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Meta-Analysis). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
