Living in Space

Living in space Living in space is not the same as living on Earth. In space, astronauts' bodies change. On Earth, our lower body and legs carry our weight. This helps keep our bones and muscles strong. In space, astronauts float. They do not use their legs much. Their lower backs begin to lose strength. Their leg muscles do too. The bones begin to get weak and thin. This is very bad for astronauts' bodies. They must exercise in space every day.
Hygiene.
On Earth, people need to stay clean. In space, astronauts need to stay clean, too. Staying clean takes more work in space. In space, the astronauts do not have a bathroom as we have at home. But, they do have their own toothbrushes, toothpaste, combs, brushes, and shavers. These are kept in a Personal Hygiene Kit. Astronauts use toothpaste and toothbrushes just like yours. There is no sink like yours on the Space Shuttle, though. Astronauts have to spit into a washcloth.
Staying neat. Doing chores is not always a fun thing. But we have to keep our rooms and houses clean and neat. In space, astronauts live in a very small space. They have to keep their area clean in space just like we do on Earth. In space, the astronauts wipe the walls, floors, and windows to keep them clean. They use a soap that kills germs. The astronauts also use wet wipes to wash things. They use the same kind of wipes and cleanser on their forks, spoons, and eating trays. Astronauts have to take out the garbage too.
Sleeping in space. Astronauts can attach themselves to a wall, a seat or a bunk bed inside the crew cabin so they don't float around and bump into something. Space Station crews usually sleep in sleeping bags. On the Space Station there are two small crew cabins. Each one is just big enough for one person. Inside both crew cabins are a sleeping bag and a large window to look out in space. Currently, Space Station crews have three astronauts living and working in space for months
