The simulated effects of microgravity significantly affect rhythmicity and sleep in humans, which could negatively affect the physiology and performance of astronauts in space.
Researchers explored how sleep and biological rhythms are impacted in simulated microgravity, highlighting challenges for astronaut health.
Astronauts exposed to microgravity experience changes to physiology, including immune suppression, increased inflammation, and reduced muscle mass and bone density.
