Spaceships are not exactly five-star hotels where astronauts stay to rest in comfortable beds and relax in fine Jacuzzis. Crew members on missions in space can’t sleep in beds, so closing your eyes after a day’s work can seem like a challenge.
Instead of lifting the sheets before bed, astronauts strap themselves in to spend the night, something that sounds logical due to the absence of gravity. Astronomers in the past have spoken of the difficulty of this method of rest, especially getting used to sleeping like this for several days.
According to different reports like this one from the International Space Station (ISS)space travelers they sleep in small resting compartments using sleeping bags and tie their bodies loosely so that their bodies do not float.
Why do they sleep tied up?
Astronauts can sleep anywhere in a spacecraft facing any direction. But it’s not good to be floating somewhere while you sleep.
To address that risk, astronomers wear sacks and are located in small sleeping compartments. They tie their bodies, loosely, so their bodies don’t float while they sleep in the space shuttle..
There are also available eye masks and ear plugs for astronauts who cannot sleep due to light or noise from air conditioning and other spacecraft machines.
The astronaut’s sleep cycle, while in a space shuttle, it’s eight hours to sleep. However, in most cases, they sleep about six hours because they usually work long hours or spend a lot of time enjoying the view outside from the window to see the stars.
