Space chronobiology: the research development on the control of circadian rhythm in spacecraft design

Objective To summarize the research development on the control of circadian rhythm in spacecraft design and to discuss the dependent shjects in designing zeitgeber of spacecraft. Literature resource and selection The professional reports, articles and books that published at home and abroad. Literature quotation Thirty-eight references were cited. Literature synthesis Space chronobiology is a rising subject on the biological rhythm, time structure, rhythm entrainment and engineering in spaceflight. The changes of space environment can affect the biological rhythm especially the circadian rhythm of astronaut's in space flight, and would be more serious with the prolonged stay in space. This article begins with the chronobiology basic knowledge in space flight, then discusses the unique environment time clue, cabin environment and zeitgeber, and further concludes with the corresponding design principles of circadian rhythm control of manned spacecraft engineering. Conclusion The control design of circadian rhythm is summarized according to the rule and characteristics of photic and other nonphotic zeitgeber of spacecraft.
