“…SWOs must work long shifts, often surpassing full-time work (40 hours a week), which may include irregular schedules and/or shift work. A wealth of research has demonstrated that these highly demanding circumstances interfere with sleep timing, sleep quality, and duration (Matsangas & Shattuck, 2020; Matsangas, Shattuck, & Saitzyk, 2020; Shattuck, Lawrence-Sidebottom, Matsangas, Riedy, & Brager, 2023; Shattuck, Matsangas, & Dahlman, 2018; Shattuck, Matsangas, Mysliwiec, & Creamer, 2019). Poor and/or inadequate sleep contributes to fatigue, degraded cognitive function, and erroneous decision-making, especially in ambiguous and/or stressful environments.…”

Several previous studies have assessed fatigue on USN warships, especially of enlisted Sailors. Our study, however, is focused explicitly on Surface Warfare Officers (SWOs) (N=34) during training and after returning to the fleet. The average daily sleep duration was 6.83±0.44 hours (62% of the SWOs sleeping <7 hours/day). The average daily sleep duration was higher when SWOs were in training compared to their fleet assignment (p=0.068). SWOs slept 0.82 hours/day more on weekends compared to weekdays in fleet settings and 0.42 hours/day when in training. Sleep efficiency during the major sleep episodes was lower in fleet settings (p<0.001), heart rate was higher (p=0.020), and HRV was lower (p<0.001). These preliminary results suggest that chronic sleep deprivation is prevalent in SWOs, especially in fleet settings. The depressed HRV during fleet assignments may be explained by the high stress levels during these periods in conjunction with the increased sleep deprivation.

This project aimed to improve the sleep, wellness, and mood of personnel standing watch on US Navy Information Warfare watchfloors. Data were collected from 82 participants on two US Navy watchfloors. Volunteers wore ŌURA rings and completed questionnaires at the beginning and end of the study. Our findings suggest that the 6-section/8-hour-shift watchbill is generally preferable to the 4-section/12-hour-shift watchbill. We developed general guidelines and recommendations for fatigue mitigation based on the data collected from the two watchfloors, the predicted effectiveness of the two watchbills calculated using the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE-FAST) model, and background literature on shiftwork. The recommendations for watchstanders focused on sleep hygiene practices, sleep environment, timing of sleep and naps, light management, the use of caffeine, alcohol, and nicotine, nutrition, and exercise.
