Structured lifestyle and behavioural interventions reduce OSA severity and daytime sleepiness in adults with obstructive sleep apnoea.
Randomised controlled trials consistently show that healthy dietary patterns, structured physical activity, alcohol reduction, and interdisciplinary lifestyle programmes can reduce OSA severity, daytime sleepiness, and cardiometabolic risk markers. Some benefits occur without substantial weight loss, suggesting additional mechanisms such as improved ventilatory stability, reduced rostral fluid shift, enhanced upper-airway neuromuscular responsiveness, and lower systemic inflammation.

Frequently Asked Questions
What lifestyle interventions are effective for OSA?▼
Healthy dietary patterns, structured physical activity, alcohol reduction, and interdisciplinary lifestyle programmes have been shown to reduce OSA severity and daytime sleepiness.
Do lifestyle interventions work without weight loss?▼
Yes, some benefits occur without substantial weight loss, suggesting mechanisms like improved ventilatory stability and reduced inflammation.
Should lifestyle interventions replace CPAP?▼
No, the paper proposes expansion, not replacement, pairing airway therapies with structured lifestyle and metabolic risk modification from diagnosis.
What are the additional benefits of lifestyle interventions in OSA?▼
They can improve cardiometabolic risk markers and potentially reduce long-term cardiovascular and metabolic complications.
