The first lesson of "Tiangong Classroom" officially started today (December 9). The astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu of the Shenzhou 13 crew gave space lectures at the Chinese Space Station.

The weightless environment will cause the blood distribution of the human body to be different from that on the ground, and the blood in the lower limbs will surge, which will affect the health of the human body. How to reduce the impact of weightlessness on the body?

Let's take a look at the secret weapon of the astronauts↓

Astronaut Zhai Zhigang:

Classmates, weightlessness has an impact on our cardiovascular system, on our bones, and on our muscles.

In order to protect our muscles from atrophy caused by weightlessness, in our space station, in addition to treadmills, bicycles, and tensioners, there is also a secret weapon.

Do students see any difference in the dress Yelaoshr wears?

There is no difference in appearance, let's take a look at its internal structure.

  These are the two adjustment rings of the chest strap, which are used to adjust the elasticity of the chest strap.

The human body is tightly bound by these pull straps, so that the muscles can maintain a certain tension for a long time, which can effectively prevent the muscle atrophy caused by weightlessness. The name of this suit is called the penguin suit.
