Summary

This study looked at how being at a real high altitude (3,000 meters in a mountain hut) compares to a machine that mimics low-oxygen conditions. Twenty healthy adults took part, and researchers measured things like brain oxygen, blood oxygen, heart rate, sleep quality, and altitude sickness. The goal was to understand the differences between real and simulated high altitude on the body and mind.
