Sleeping in Space: Astronauts' Solutions.

Astronauts face challenges in sleeping during space missions due to the unique space environment and the need to establish a natural sleep cycle. NASA researchers are developing tools to help astronauts overcome sleep challenges, including managing exposure to blue light and shifting sleep schedules. Simulated missions on Earth, such as the Human Exploration Research Analog, allow for more control and data collection. NASA is also monitoring the sleep of Earth-bound scientists and engineers working on Mars missions to better understand the effects of the planet's longer day on the human body. Understanding sleep is crucial for astronaut performance, alertness, and relationships during long-duration missions to Mars.
