In plain words

What the trial is, and whether it could suit you

Sleep organization and cardiorespiratory parameters are disrupted in extreme conditions such as high altitude. The pathophysiology of medical problems related to acute high-altitude exposure is partially understood, but sleep quality indicators are very rarely measured under these conditions. This lack of information is even more pronounced among employees subjected to cyclical exposure to high-altitude hypoxic stress, as is the case for the employees at the Pic du Midi. These 32 employees regularly report to their occupational physician difficulties in managing their sleep disorders, struggling to distinguish symptoms from objective changes in their sleep cycles. Among them, 13 are on call at the summit of the Pic du Midi (2,877 m), while 19 work there during the day and return home to a lower altitude at night to sleep. The investigators also wish to measure structural changes in sleep
