First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether breathing extra oxygen can improve thinking and reaction time in healthy people who live at high altitude (about 2500 meters). Fifty Kyrgyz adults will receive both real oxygen and a sham treatment to compare. The goal is to see if mental changes caused by low oxygen are reversible.
