Simple breathing training may ease fibromyalgia pain and fatigue
NCT ID NCT07261696
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a simple breathing exercise, called inspiratory muscle training, can improve the body's stress response and reduce symptoms like pain, fatigue, and sleep problems in women with fibromyalgia. Fifty-one women will be randomly assigned to real training, a sham version, or no training for six weeks. Researchers will measure heart rate variability and use questionnaires to track changes.
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 using a Powerbreathe® device
- What this could lead to
- If it works, this could offer a simple, low-effort exercise option to help manage fibromyalgia symptoms like pain, fatigue, and poor sleep.
- What could go wrong
- This is a small, early-stage trial with only 51 participants. The sham group may also show benefits, and results may not apply to men or people with other health conditions.
