【摘要】 航天员在轨睡眠一直存在着睡眠时间减少、睡眠质量下降等问题,从而影响了航天员的认知功能。本文综述了在轨睡眠问题及其对航天员认知功能影响的研究进展,对已有影响因素进行分析,并对现阶段针对在轨睡眠问题的研究方法进行了简述和展望,以期更好地为在轨睡眠评价体系的研究提供参考,进而辅助航天医学研究,确保航天员在轨工作的正常进行。更多还原

【Abstract】 The problems such as the reduction of sleep time and the decline of sleep quality have long existed in on-orbit sleep of astronauts. Further studies have shown that these problems may cause a decline in cognitive ability of astronauts. The studies of on-orbit sleep and its effect on astronauts’ cognition as well as the analysis of different influencing factors were reviewed in this paper. Furthermore,the prospects of on-orbit sleep researches in the future were also discussed to provide references for the studies of on-orbit sleep evaluation system and to assist the space medicine researches so as to ensure the normal operation of astronauts.更多还原
