Could your workout breathing harm your eyes? new study investigates
NCT ID NCT07326462
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how different breathing patterns during strength exercises change eye pressure and blood flow in the retina. Sixty healthy adults aged 18-40 will perform exercises with normal breathing or a breath-holding technique called the Valsalva maneuver. Researchers will measure eye pressure, retinal vessel size, and other health markers before and after exercise to find the safest way to train.
