NASA: Insufficient sleep endangers astronauts, jeopardizes space missions

NASA reveals that insufficient sleep poses "catastrophic" health risks for astronauts in space, potentially endangering missions. New data indicates sleep deprivation on the International Space Station can lead to severe, long-term health consequences for astronauts. Zero-gravity conditions and disrupted circadian rhythms contribute to sleep difficulties. To mitigate these effects, NASA is implementing measures like adjusted lighting and private sleep areas, while emphasizing the importance of adequate rest for astronaut safety and mission success.
