[036] FACTORS INFLUENCING ASTRONAUT SLEEP DURATION DURING SPACEFLIGHT

摘要

INTRODUCTION: In the spaceflight environment, astronauts are exposed to many factors that put them at risk for health and performance decrements. Sleep loss caused by circadian desynchrony, medication use, work overload, and various other environmental factors can compromise mission success and astronaut safety by negatively affecting astronauts' performance in space. Despite many studies being conducted on sleep in space, there is little consensus on the factors that influence sleep duration. Prior research has been limited by small sample sizes and varying methodology used to study sleep outcomes. To better understand the effect of microgravity and spaceflight on sleep outcomes, we conducted a literature review summarizing data collected during -spaceflight using electroencephalogram (EEG), actigraphy, and sleep logs.
