Astronauts and space mission planners lack practical solutions for managing severe sleep disruption in microgravity environments

Astronauts experience significant sleep quality degradation in microgravity due to environmental factors (constant light, noise, temperature fluctuations, inability to maintain natural sleep posture) and physiological changes, yet current countermeasures are inadequate. Space agencies and mission planners struggle to optimize crew performance and safety because they don't have evidence-based interventions specifically designed for the unique constraints of spaceflight environments. Existing terrestrial sleep solutions fail to account for the physics of microgravity and the psychological stress of space missions.
