First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a breathing exercise program can reduce daytime sleepiness in adults with obstructive sleep apnea who already use a CPAP machine. Participants will do 12-20 minute sessions of inhaling against resistance three times a week. The goal is to see if strengthening the breathing muscles can improve alertness and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- inspiratory muscle training (breathing exercises using a resistance device)
- What this could lead to
- If it works, this could offer a simple, drug-free way to reduce daytime sleepiness for people with sleep apnea who already use CPAP.
- What could go wrong
- This is a small, early-stage trial with only 58 participants. Previous studies on this technique have shown mixed results, so it may not prove effective.
