Simulated microgravity affects sleep and physiological rhythms

Simulated effects of microgravity significantly affect rhythmicity and sleep in humans, a new study from the University of Surrey finds. Such disturbances could negatively affect the physiology and performance of astronauts in space. Previous findings have shown that astronauts exposed to microgravity, simulated via 60 days of constant bed rest at a six-degree head-down tilt … Read more
