Carrying the expectations of countless people, the Shenzhou 16 successfully returned.

The Shenzhou 16 astronauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao all safely and smoothly exited the spacecraft. Jing Haipeng has flown in space for over 200 days on four occasions, making him the Chinese astronaut with the highest number of flight missions so far. China's first aerospace flight engineer Zhu Yangzhu and the first payload expert Gui Haichao also successfully completed their first flight.

However, just as the three astronauts left the spacecraft, there was such a detail that I don't know if everyone had noticed.

That's because all three of them have abnormal facial expressions. Their faces are slightly reddish, and compared to the photos taken before the launch of Shenzhou 16, their faces also show obvious swelling.

Not only that, but we can also notice from the live broadcast footage that,After leaving the cabin, all three astronauts were lifted onto "stretchers" and carried away.

Based on this, many attentive viewers are very worried that there may be problems with the physical health of astronauts.

So, the three astronauts of Shenzhou 16,Why is the face red and swollen after leaving the cabin? Why are they being carried on stretchers and carried away?

Reset of body fluids under weightlessness

Speaking of it, the facial swelling of the three male astronauts on Shenzhou 16 is not particularly noticeable compared to the female astronauts Liu Yang and Wang Yaping who returned from the space station.

Let's take a look at the photos taken by Liu Yang and Wang Yaping when they first returned from the space station.

Compare these two photos again, the two of them took photos before going to the space station.

By comparison, we can clearly see that,After returning from the space station, their faces showed swelling.

The reason for this situation is that on the surface of the Earth, body fluids are more concentrated in the lower part of the body under the action of gravity.In a weightless environment, although blood flow is normal, the distribution of blood is completely different,Due to microgravity, blood is almost evenly distributed throughout the body, with the most obvious change being an increase in bodily fluids in the upper body, which can be seen on the face.

Why should astronauts be carried away on stretchers?

In the video footage transmitted back from now on, it is not difficult to find that the three astronauts of Shenzhou 16 are unable to leave the spacecraft immediately after landing in the return module. They need to stay for at least an hour, and the first to come into contact with the astronauts are medical supervision and insurance personnel. They first need to communicate with the astronauts to understand their physical condition and confirm that there are no problems before assisting them in leaving the spacecraft.

Effects of microgravity on human muscles

Why are astronauts carried away on stretchers when they return to Earth? This is becauseIn the microgravity environment of space, the force on any active muscle is very small, almost completely unused. In the short term, muscle mass loss during space flight will reach10% -15%If there is a long-term space flight, this data can even be usedUp to 50%.

Loss of calcium in weightless environments

Prolonged exposure to weightlessness can also have a significant impact on the bones of the human body, especially causingThe loss of calcium ultimately leads to the loss of bone mass,NASA1%-1.5%.

Normal vertebrae and vertebrae with osteoporosis

Not only that,The spacesuits worn by astronauts may not weigh as much as the extravehicular spacesuits, but they weigh at least a few tens of pounds,.

For these reasons, as soon as the astronauts returned to Earth, they needed to be carried away on stretchers
