Sleep Loss and Fatigue

Researchers in our Sleep and Fatigue Laboratory are working to improve the health and readiness of warfighters by developing novel solutions for monitoring sleep in operational settings and creating effective strategies to reduce the impact of fatigue and sleep loss.



Sleep loss and fatigue compromise the performance, health, and safety of warfighters. To maximize the operational readiness and resilience of our armed forces, the Sleep and Fatigue Research Laboratory develops and implements practical, evidence-based solutions for managing the negative effects of sleep loss and fatigue in military environments.


    The research done by our Sleep and Fatigue team supports health and readiness by developing operational relevant tasks to assess the effects of sleep loss/circadian disruption and fatigue on warfighter performance, reducing insomnia symptoms using evidence-based behavioral treatment approaches, and seeking solutions for monitoring sleep and fatigue outside the laboratory in realistic, operationally relevant settings.


  • Optimize the operational readiness and resilience of our armed forces through research by assessing, evaluating, and mitigating the effects of sleep loss and fatigue on warfighter performance and health
  • Provide guidelines for leaders that emphasize the importance of sleep for operational performance and resilience


  • Conduct sleep and fatigue research in operational environments or our 2-bedroom sleep laboratory
  • Monitor sleep using both gold-standard, laboratory based polysomnography and innovative technologies
  • Conduct sleep disorder diagnostics
  • Conduct integrative performance assessments using NHRC’s immersive virtual reality environment in our Warfighter Performance Laboratory
  • Implement evidence-based treatments for sleep issues and countermeasures for fatigue


  • Validation of innovative technology for assessing sleep and detecting sleep disorders
  • Development of operationally relevant fatigue assessment and prediction tools
  • Identification of countermeasures for sleep loss and fatigue
  • Implementation of behavioral treatments to reduce insomnia symptoms
