“…By measuring participants' sleep quality the night prior to the experiment, we found that participants' sleep quality and their exposure time in a nauseating virtual environment are negatively correlated. This aligns with previous suggestions that a lack of sleep or shortened sleeping hour the night prior to exposing to challenging environments could lead to increased motion sickness severity [4,12]. This suggested that VR users should be advised to have sufficient rests before exposing to provoking stimulus.…”

Sleep quality, spatial ability, and pain sensitivity had been suggested to affect cybersickness discomfort. This study evaluated various human factors on the cybersickness symptoms and tolerance duration in a nausegenic virtual environment. Results showed that the participants with better sleep quality had better cybersickness tolerance. Further, participants with lower pain threshold had slightly lower cybersickness tolerance and reported more cybersickness symptoms.

“…Their results suggested that participants that exposed to the oscillation with shorter sleeping hour experienced more motion sickness discomfort (see also [12]). Their rate of adaptation to motion sickness over repeated exposure was also slower than the control group.…”

“…Although previous studies have linked poor sleep with negative performance and psychological outcomes in active-duty military [61,63], there has been limited research on the link between sleep and relevant occupational outcomes in this unique population. The objective of this work was therefore to examine the link between sleep quality and occupational functioning in an elite unit of US Army soldiers.…”

We aimed to assess the relationship between subjective sleep quality and occupationally-relevant outcomes in military personnel. Participants were from an elite unit of US Army soldiers who worked extended (~30 h) shifts (with minimal recovery time between shifts) during 3-week work sessions. Questionnaires assessing subjective sleep quality during the month prior (Pittsburgh Sleep Quality Index [PSQI]) were administered at the beginning of the session. Occupational outcomes (emotional exhaustion, functional impairment, role overload, daytime sleepiness) were assessed on the final day of the session. Regression analyses were conducted to link sleep quality and occupational outcomes. The study sample participants had relatively poor sleep prior to the exercise (PSQI Global score average = 6.3 ± 3.1). Higher PSQI Global Scores prior to the work session longitudinally predicted daytime sleepiness (f2: 0.56) after the work session. PSQI component 7, which queries daytime dysfunction attributed to poor sleep quality, longitudinally predicted emotional exhaustion, functional impairment, and role overload (f2 range: 0.19–0.70). In conclusion, poor sleep quality—in aggregation with occupationally-mandated sleep loss—is predictive of poorer subsequent occupational outcomes. Future work should aim to increase sleep opportunities prior to occupationally-mandated sleep loss in order to build resilience when sleep loss is unavoidable.

“…18 The risk for MSKI increases as sleep duration decreases. 19 Sleep deprivation has been associated with increased risk taking, 20 decreased pain tolerance, 21 and decrements in balance 22 likely contributing to the increased MSKI risk. In addition to the physical toll, service members are also at risk for psychological disorders in the context of sleep deprivation.…”

During multi-domain operations (MDO), soldiers need the physical supremacy, cognitive dominance, and emotional resilience to help defend and win our nation's wars. Optimal sleep has been shown to boost physical performance and cognitive processing. This manuscript will discuss how recent advances in sleep science strongly argue for the integration of sleep planning into military operations. Design: Review article. Methods: We reviewed the current understanding of how sleep affects Soldier readiness, how sleep and pain are interrelated, and unique challenges to obtaining adequate sleep in military training environments. We then address solutions that can be implemented by leaders and individuals to manage warfighter fatigue and optimize unit performance. Results: Since sleep is foundational to soldier health and readiness, improving warfighter fatigue management is a priority for leaders. Conclusion:To succeed in MDO, military personnel require physical supremacy, cognitive dominance, and emotional resilience to fight and win. Sleep science is a rapidly emerging field, and the clear implications for maximizing human performance argue strongly for more deliberate integration into military training and operations. Leaders that incorporate sleep and fatigue management into the planning and execution phases of operations will help facilitate mission priorities and prove a powerful force multiplier.
