First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at how sleeping at low versus moderate altitude changes sleep test results in 44 healthy adults who live at high altitude. Participants spent one night at low altitude and one at moderate altitude, and their sleep was monitored with a full set of sensors. The goal was to see if altitude affects key measures like oxygen levels and breathing pauses during sleep.
