Sleeping at the ISS 💤 Astronauts sleep in space by using tethered sleeping bags to prevent floating in microgravity. They follow a strict sleep schedule, often using artificial light to maintain their circadian rhythm, as the space station orbits Earth every 90 minutes. There’s no need for pillows, as their heads float freely. Let us know your thoughts below!
