Many aspects of Shuttle missions may have significant impact on the normal sleeping patterns of crewmembers. Using a standard debriefing form, 58 crewmembers from 9 Shuttle flights (6 single-shift flights, and 3 dual-shift flights) were debriefed within 3 d postflight. Specific questions on the form relating to sleep quality and quantity, fatigue, and sleep medication usage during all flight phases were analyzed. Of crewmembers on dual-shift missions 50% (11 of 22) used sleep medications at least once inflight compared to 19.4% (7 of 36) of single-shift. The biggest impact on normal sleep patterns occurred during the first and last days of a mission, with averages of 5.7 h and 5.6 h, respectively. These results suggest that sleep disruption is a common occurrence on Shuttle missions. Further studies are suggested to develop strategies for coping with this potential problem.
航天飞机任务的许多方面可能会对机组人员的正常睡眠模式产生重大影响。使用标准的任务汇报表，对来自9次航天飞机飞行任务（6次单班飞行和3次双班飞行）的58名机组人员在飞行后3天内进行了任务汇报。对表格中有关所有飞行阶段的睡眠质量和数量、疲劳以及睡眠药物使用情况的具体问题进行了分析。在双班任务的机组人员中，50%（22人中有11人）在飞行中至少使用过一次睡眠药物，而单班任务的这一比例为19.4%（36人中有7人）。对正常睡眠模式影响最大的是任务的第一天和最后一天，平均睡眠时间分别为5.7小时和5.6小时。这些结果表明，睡眠中断在航天飞机任务中很常见。建议进一步开展研究，以制定应对这一潜在问题的策略。
