In order to avoid muscle tissue degradation

But while on the International Space Station, astronauts use a specially designed bathroom. There, specially designed devices suck up waste, turning urine into drinking water, and all solid waste is compressed and sent to the multifunctional Progress spacecraft, which unloads all the garbage into the Earth's atmosphere, where it burns up before it reaches our goals. In order to learn how to use a space toilet, astronauts undergo special training on Earth, because the opening of this device, so important for life in orbit, is quite small and does not at all resemble its terrestrial counterpart.

After training, astronauts sweat profusely and then use this liquid to drink.
To prevent or at least slow down the muscle strain that occurs in uae number data weightlessness, all astronauts on the ISS must exercise for at least 2 hours a day. Active physical activity causes sweat to appear, which behaves very differently than on Earth. In weightlessness, sweat doesn't drip from your skin; it sticks to you and forms small droplets. You can swim with these droplets of sweat on your body, but astronauts wipe all the liquid with a special towel, collect it, and filter it. Like urine, the filtered sweat is consumed as drinking water.


astronauts must spend at least 2 hours a day on the treadmill.

It's better not to cry in space.
Despite the opportunity to observe the picturesque view of the bright blue Earth from the ISS portholes every day, homesickness can seize anyone and make them want to cry, thereby relieving their emotional state. However, astronauts are better off not missing home and not shedding tears in space. In conditions of weightlessness, tears do not flow down the cheek, but remain around the astronaut's eyes and sting painfully.
