a)    Initial State

The Reaction Self Test investigation will help characterize the relationship between sleep quantity, circadian desynchronization, work overload, and performance in spaceflight. Task and team performance data from operational tasks in spaceflight however are not available. Sleep and circadian systems are fundamental aspects of psychological, psychosocial and physiological well being. As noted by the SRP, understanding how decrements in sleep and circadian rhythmicity impact behavioral health on orbit is essential to mitigating risk and preparing for future long duration exploration missions. Hence, a more multidisciplinary approach to research should be implemented.

b)    Target for Closure

Identified set of individual and team behavioral health and performance outcomes, and the characterization of the relationship between  sleep loss, circadian desynchronization, extended wakefulness and work overload, to these outcomes, for three mission profiles, including missions over 12 months and greater distance.

c)    Metrics for Interim Progress

(1) Develop a framework based on existing literature, defining relevant outcomes and their relationships to risk factors (Mars-520 Day study) (10%);
(2) Identify from spaceflight research, where data mining could be conducted (e.g., sleep data and correlates to shuttle landing data) (10%);
(3) Implement BHP Dashboard Study (Bmed2) to aggregate various data sources and conduct contextual assessment of spaceflight (30%);
(4) Collaborate with other disciplines to implement or support investigations (e.g., HERA) that
are multidisciplinary, evaluating sleep loss, etc., as potential contributor to different behavioral, performance, and physiological outcomes (40%);
(5) Database containing final set of relevant  and measurable performance outcomes and their relationship to risk factors  extrapolated to 3 mission profiles (10%).

d)    Approach

Comprehensive study currently cataloged in BMED, will be implemented; BHP to advocate to HRP research community to consider sleep and circadian phase in investigations related to health and performance in space. Investigators evaluating behavioral, psychosocial and physiological outcomes should consider sleep, workload and circadian phase as potential contributors to their outcomes.

Risk Risk of Performance Decrements and Adverse Health Outcomes Resulting from Sleep Loss, Circadian Desynchronization, and Work Overload
You are here! Gap Sleep Gap 2: We need to understand the contribution of sleep loss, circadian desynchronization, extended wakefulness and work overload, on individual health (physical and behavioral), team functioning, and performance (including operational performance), for spaceflight.
