Sleep Environment Recommendations for Future Spaceflight Vehicles

We conducted a literature review and subject matter expert survey to determine the parameters required for an optimal sleep environment in space. We reviewed the effect that light, noise, temperature, air quality/humidity, and comfort have on sleep quality. We also reviewed lessons learned from spaceflight analog environments and virtually every past spaceflight vehicle. Additionally, we interviewed individuals with extensive experience around living and sleeping in extreme environments (including astronauts, pilots, military personnel, and oil rig workers). This study has been completed and the results have been published.
