Abstract

This study characterizes, for the first time, the lives of U.S. Navy submariners engaged in normal, sea-based operations while following a circadian-aligned 24-h watchstanding schedule. Fifty-eight submarine crewmembers provided objective (actigraphy) and subjective (questionnaires) sleep data, and information about mood and lifestyle behaviors during 30 days underway. Projected performance scores and estimated circadian phase times were also calculated from actigraphy-based sleep/wake data. Submariners’ objective (6.62 ± 0.94 h; mean ± SD) and subjective (5.90 ± 1.38 h) daily sleep quantities while underway were largely comparable to the sleep reportedly received by Sailors across other Navy platforms and watchstanding schedules. Additionally, submariners' actigraphy-predicted circadian phases shifted progressively toward better alignment with watchstanding schedules across time. Nevertheless, subjective sleep quality was low, submariners engaged in unfavorable lifestyle behaviors (lack of regular meals and exercise), and participants reported decreased mood at the completion of their underway time. Recommendations for countermeasure development are provided.

潜艇上的生活：按昼夜节律值班的水手的睡眠、疲劳和生活行为。

这项研究首次描述了美国海军潜艇艇员在按照昼夜节律调整的 24 小时值班表进行正常海上作业时的生活状况。58 名潜艇艇员在 30 天的航行期间提供了客观（动图）和主观（问卷）睡眠数据，以及有关情绪和生活行为的信息。此外，还根据基于动觉仪的睡眠/觉醒数据计算了预计的绩效分数和估计的昼夜节律相位时间。潜艇兵在航行期间的客观睡眠时间（6.62 ± 0.94 小时；平均值 ± SD）和主观睡眠时间（5.90 ± 1.38 小时）与其他海军平台和值班时间表的水兵的睡眠时间大体相当。此外，潜艇兵的昼夜节律预测相位随着时间的推移逐渐与值班时间表更加一致。然而，主观睡眠质量较低，潜艇兵有不良生活方式（缺乏定时进餐和锻炼），而且参与者报告说，他们在值班时间结束后情绪低落。本文提出了制定对策的建议。
