Salt mine therapy tested for COPD relief
NCT ID NCT07122544
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether doing pulmonary rehabilitation in underground salt chambers improves breathing, exercise ability, and quality of life in people with COPD. 80 adults with stable COPD will be split into four groups: rehab in salt chambers, rehab in a gym, just sitting in salt chambers, or health education only. Researchers will measure changes in walking distance, symptoms, and muscle strength right after the 16-day program and again three months later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pulmonary rehabilitation in therapeutic salt chambers
- What this could lead to
- If it works, this could offer a new way to improve exercise tolerance and quality of life for people with COPD.
- What could go wrong
- This is a small, early-stage study with 80 participants. The benefits of salt chamber therapy are unproven, and results may not apply to all COPD patients.
