How do astronauts sleep in space?

Browse → Science → Space

Usually after a long day of work, an astronaut will settle in for a much needed eight hours of sleep. Sleeping in a space shuttle or on the space station is a lot different than sleeping down on Earth.

How do you sleep? You probably have a bedroom with a bed.  Astronauts often have only very tiny rooms to sleep in, and there isn’t enough room for a bed. They often sleep in small compartments or in sleeping bags!

The biggest difference between sleeping on Earth and sleeping in space is gravity.  In space, there is no gravity to pull people down.  Without gravity, there actually isn’t really any up or down at all! Sometimes astronauts sleep standing up!  Also, so that they don’t float away and bump into things while they sleep, astronauts will often strap their sleeping bags to the walls!
