Effects of Mild Hypobaric Hypoxia on Sleep and Post-sleep Performance

Completed · Not applicable

Conditions studied: Altitude, Hypoxia, Environmental Sleep Disorder

In brief

Hypobaric hypoxia (decreased oxygen supply to body tissues due to low atmospheric pressure) caused by exposure to high altitude disrupts sleep. Sleep deprivation is associated with degraded post-sleep performance of neurobehavioral tasks. The lowest altitude at which sleep and/or post-sleep performance are affected is not known. The study hypothesis is that sleep and/or post-sleep performance of neurobehavioral tasks will occur due to hypobaric hypoxia at altitudes of 8,000 or less.
