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.
788 studies on the registry are indexed under Sleep Wake Disorders; 186 are open to participants now.
This study's enrollment of 34 is below the median of 62 across 548 interventional studies indexed under Sleep Wake Disorders.
