Sleeping in space is part of space medicine and mission planning, with impacts on the health, capabilities and morale of astronauts.
Human spaceflight often requires astronaut crews to endure long periods without rest. Studies have shown that lack of sleep can cause fatigue that leads to errors while performing critical tasks.[1][2][3] Also, individuals who are fatigued often cannot determine the degree of their impairment.[4] Astronauts and ground crews frequently suffer from the effects of sleep deprivation and circadian rhythm disruption. Fatigue due to sleep loss, sleep shifting and work overload could cause performance errors that put space flight participants at risk of compromising mission objectives as well as the health and safety of those on board.
