What are the interesting lifestyles of astronauts?

1, confused feeling and strange sleeping position

It is indeed a "confused feeling" for astronauts to sleep in space. One of its manifestations is that it is black and white, and the other is that it sleeps strangely.

Black and white refers to astronauts sailing around the earth in the sky, sometimes sunrise and sunset alternate many times in 24 hours. Astronauts can't follow the life habit of "working at sunrise and resting at sunset" on the earth, so they can only arrange their work and sleep mechanically according to the hours.

Strange sleeping position means that astronauts can't find the feeling of "lying down" in the weightless environment of space. In the weightless environment, people lose the reference coordinates of "up" and "down", their feet can't reach the ground, and the sky is all around them, so they can't tell up and down at all. Therefore, there is no such thing as lying flat when sleeping.

2. Strange washing face and brushing teeth

Because of the weightless environment in space, washing face, brushing teeth, shaving, haircut and washing are seemingly simple things on earth, which become very complicated and troublesome in space.

Take brushing and gargling as an example. At first, Americans chewed with a special kind of chewing gum instead of brushing their teeth, while Soviet astronauts massaged with their hands and scrubbed their mouths with towels instead of brushing their teeth.

Now astronauts use a sealed razor, which can be connected to a vacuum cleaner through a sealed tube, and the vacuum cleaner can suck stubble into a garbage disposal box.

Extended data:

The space environment is very different from the earth environment. There is no air, no gravity and dangerous space radiation. Of course, there is enough air for you to breathe in a closed space station or space shuttle cabin. Good spacecraft shielding materials can effectively block space radiation, but "weightlessness" will bring some troubles to life.

The astronaut's menu is also very rich, with 100 choices. However, space food is not ordinary fruits and vegetables, but specially processed "compressed bricks" or "toothpaste tubes". After a certain proportion of water, it can be restored to its original shape, tastes good and contains all the nutrients needed by the human body.
