How do astronauts sleep in space?

Astronauts sleep in space with special sleeping bags. Fixing the sleeping bags in a certain area can exert a certain pressure on the astronauts, making their bodies stick close to the cabin, creating a feeling similar to lying in bed in a gravity environment.

Astronauts will also have their own dedicated cabins when sleeping, which can be separated by curtains to protect personal privacy.

Due to the influence of the microgravity environment, people are in a floating state in space. Without the restraint of gravity, astronauts may fall asleep while floating.

The space food for astronauts is very rich, and has developed from the initial dozen or so to more than a hundred types.

What is the principle of human sleep?

The principle of human sleep is that after the nerve cells in the cerebral cortex are excited, they will produce inhibition. When the inhibition is dominant in the cerebral cortex, people will feel sleepy and fall asleep. This is a physiological reaction. Sleeping is one of the indispensable physiological phenomena of human beings.

Generally speaking, if a person does not sleep for 18 hours, the human reaction time will change from 0.25 seconds to 0.5 seconds and continue to grow, so sleeping can keep people energetic and healthy.

Most people are used to sleeping lying down, but animals in nature sleep in many different ways. According to their habits, most of them sleep standing up. Bats sleep upside down, and owls sleep with one eye open and one eye closed.

The correct sleeping posture on the plateau

The correct sleeping position on the plateau: lying on the right side. When sleeping on the plateau, it is recommended to sleep on the right side. Because when sleeping on the right side, the heart is in a high position and the liver is in a low position, so the pressure on the heart is relatively small and it helps to provide oxygen to the human body.

Maintain a good mental quality and stay optimistic. If you worry too much, feel anxious, and have poor sleep, it will increase the oxygen consumption of brain tissue, leading to or aggravating altitude sickness.

On the plateau, you must pay attention to keeping warm in your clothes. Even in summer, you should prepare woolen sweaters and thermal underwear. In winter, the temperature is lower, so you need to pay more attention to cold protection.

On the plateau, you should choose high-calorie and easily digestible foods, avoid overeating, and be careful not to overeat at dinner, so as not to increase the burden on the stomach and intestines and cause chest tightness and panic.
