Key topics and learnings
Light is a potent stimulus for regulating human biology and has the capacity to restore health in clinical applications, such as treating winter depression and sleep disorders. In addition, light therapy has been evaluated for healthy individuals who experience sleep-wake disruption associated with intercontinental jet travel, shift work and spaceflight. Studies are in process testing a prototype solid state light system for supporting astronaut vision as well as sleep-wake rhythm, neuroendocrine, neurobehavioral and sleep regulation in crewmembers on the International Space Station. Development of such advanced lighting technologies opens the door to innovative architectural applications in public facilities, work places and homes.
