Gravity is such an important force of attraction. Earth’s gravity is so strong that it attracts living things, to objects from outer space.
Gravity is very important for living things, even in matters of eating and defecating. But what about the astronauts in outer space without gravity?
Personal hygiene, such as bathing regularly, urinating, and defecating is very important to support health.
But what if you are more than 200 miles above the Earth’s surface?
How do they do their daily routines like bathing?
Bathing is something that must be done by humans to remove stains or dirt and dirt that sticks to the body. Of course, if on earth, bathing requires water as a wash, it turns out that it is a little different if someone wants to clean the body in outer space.
Because in outer space there is very low gravity, so everything can float around aimlessly. The same goes for water.
In a video that was uploaded on YouTube featuring an astronaut named Chris Hadfield who was on the International Space Station (ISS), he showed that when water is in space, this liquid will form like a gel floating in the air.
Because it is feared that it can damage the equipment on the plane or space station and to save it, considering that water is a very valuable thing in outer space, there is a special way for an astronaut to clean his body.
On the plane or the space station, astronauts have been provided with a special place to clean the body with a cylindrical system that uses a plastic bag.
When in a special place, an astronaut can use a special wet sponge or foam that can be used to wash the body. To avoid splashing water floating into the air, then that is the main function of the cylinder system that can suck up the lumps of water.
Astronauts also shower with soap but they don’t need water to rinse. Reporting from the NASA page, the soap is specially designed like the one in the hospital. Usually people who are seriously ill can not go to the bathroom so they use soap without water. After the shower, they have to make sure the foam doesn’t float all over the place.
After the activity of washing the body is complete, the plastic bag containing the water must be tightly closed, then the astronaut is obliged to put a new plastic bag in that place for other astronauts who will wash the body.
Cleaning teeth in space is an important thing to do. But not for the usual reasons. According to the European Space Agency (ESA), astronauts always clean their teeth because the force of acceleration and vibration during flight can make teeth hurt, especially if there are cavities or fillings.
Then how to do it? It turned out that there was nothing special, they still used regular toothbrushes and toothpaste. But because they have to reduce their water use, they usually have to swallow the toothpaste or spit it out onto a towel.
Like most people, astronauts bring their own cleaning equipment. Among them are deodorant, soap, comb, toothpaste, toothbrush, shaver, plastic bag, and others. Usually they carry more than one item for each equipment considering there is no shop that can meet their needs.
