Can your smartwatch track your breathing? scientists put it to the test
NCT ID NCT07578389
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study checks if a smartwatch can measure how fast you breathe as accurately as medical devices like spirometers. Sixty healthy adults will wear the watch while their breathing is also measured by standard hospital equipment. If the watch is reliable, it could one day help people monitor their breathing at home without special gear.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- smartwatch-based respiratory rate monitoring
- What this could lead to
- If the smartwatch proves accurate, it could enable reliable at-home breathing monitoring for people with respiratory conditions.
- What could go wrong
- This is a small, early-stage study in healthy volunteers only. Real-world accuracy in patients with breathing problems remains unknown.
