Sufficient sleep duration and good sleep quality are crucial to ensure normal physical and mental health, cognition and work performance for the common people, as well as astronauts. On-orbit sleep problem is very common among astronauts and has potential detrimental influences on the health of crewmembers and the safety of flight missions. Sleep in space is becoming a new medical research frontier. In this review we summarized on-orbit sleep problems of astronauts and six kinds of causes, and… 

Commentary regarding “on-orbit sleep problems of astronauts and countermeasures”

This commentary addresses the article by Wu et al. entitled “On-orbit sleep problems of astronauts and countermeasures” and describes a possible approach to reducing light flashes using the fact that much of the galactic cosmic radiation (GCR) spectrum is composed of ions that can be diverted from the spacecraft using electromagnetic fields.

Sleep in Isolated, Confined, and Extreme (ICE): A Review on the Different Factors Affecting Human Sleep in ICE

A systematic review of research findings on sleep disturbances in ICEs is presented, looking for evidence from studies run in polar settings during space missions, Head-Down Bed-Rest protocols, simulations, and in a few ICE-resembling settings such as caves and submarines.

India’s Manned Spaceflight: Incisive Perspectives on the Vigilance of the Crew During the Mission

During staffed space flight missions, the astronauts’ circadian timing system and sleep are altered not only due to the microgravity environment but also due to the intense environmental stimulus.

Analysis of sleep on Shuttle missions.

The results suggest that sleep disruption is a common occurrence on Shuttle missions and further studies are suggested to develop strategies for coping with this potential problem.

Uncovering Residual Effects of Chronic Sleep Loss on Human Performance

Extended wake during the circadian night reveals the cumulative detrimental effects of chronic sleep loss on performance, with potential adverse health and safety consequences for employers.

Circadian misalignment affects sleep and medication use before and during spaceflight

It is suggested that there is an immediate need to deploy and assess effective countermeasures to minimize circadian misalignment and consequent adverse sleep outcomes both before and during spaceflight.

The alteration of human sleep and circadian rhythms during spaceflight

Most likely, altered circadian zeitgebers on MIR and a deficiency in the process S of Borbély's sleep model cause the observed findings, and the change in process S may be related to changes in physical activity as a result of weightlessness.

Investigation of the effectiveness of a split sleep schedule in sustaining sleep and maintaining performance

Whether a split sleep schedule is as effective as a consolidated day shift or night shift schedule for maintaining performance and sustaining sleep is examined and subjective sleepiness was highest in the daytime sleep condition and lowest in the nighttime sleep condition.
