Designing Individual Countermeasures to Reduce Sleep Disruption and Improve Performance and Alertness in Space (Completed)

Last Published: 07/31/19 10:05:33 AM (Central)

Task Book: Entry
Principal Investigator: Klerman, Elizabeth

Short Title: Mathematical Model Harvard

Responsible HRP Element: Behavioral Health and Performance

Collaborating Org(s):

National Space Biomedical Research Institute (NSBRI)

Other:

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Solicited

Aims:

(1) Replace the current assumption that an individual sleeps when scheduled to sleep, with probabilities of sleep and wake during those times

(2) Improve daily assessment of sleep and sleep disruption using actigraphy data

(3) Add statistical features including confidence limits to the predictions

(4) Update the software per astronaut and ground crew requests for specific features and reports

Deliverables (1)

Category: Technology or Tool
Subcategory: Computational Models or Simulations

Description:
Prototype software delivered to BHP (within six months following completion of task). This modeling effort may be incorporated as a larger suite of models aimed to support mission and medical operations as they make scheduling decision. A decision point (involving Ops feedback) will follow this task to determine next steps.

Risk of Performance Decrements and Adverse Health Outcomes Resulting from Sleep Loss, Circadian Desynchronization, and Work Overload

Sleep Gap 4: We need to identify indicators of individual vulnerabilities and resiliencies to sleep loss and circadian rhythm disruption, to aid with individualized countermeasure regimens, for autonomous, long duration and/or distance exploration missions.

Sleep Gap 8: We need to develop individualized scheduling tools that predict the effects of sleep-wake cycles, light and other countermeasures on performance, and can be used to identify optimal (and vulnerable) performance periods during spaceflight.
