Evaluation of Changes in Sleep Efficiency Among PIC DU MIDI Employees Between Nights Spent at Home and Nights Spent in a High Altitude Work Environment

What this Trial Is About

This research aims to evaluate changes in sleep efficiency and cardiorespiratory parameters among employees who work under high-altitude conditions at the Pic du Midi. The study focuses on understanding sleep disruptions caused by acute exposure to high altitude, especially in employees who experience cyclical hypoxic stress. It seeks to clarify sleep quality indicators which are rarely measured in such extreme environments. The study compares two groups of employees: those who spend the night at high altitude (2877 meters) while on call at the Pic du Midi summit, and those who work during the day but sleep at home at lower altitude. Sleep recordings using polysomnography and questionnaires are used to monitor and compare nights spent at home versus nights spent at high altitude. This includes a one-week observation period following participant inclusion. Participants will undergo sleep efficiency monitoring, measuring total sleep time compared to total sleep period, alongside evaluation of various sleep and cardiac parameters. Questionnaires help assess sleep disorders and their correlation with sleep quality. The study monitors participants for one week after inclusion and compares sleep data across groups to better understand the impact of high-altitude work on sleep patterns and related health parameters.
