Why do astronauts grow tall when they return to earth? The reason is heartbreaking

Since the 21st century, with the great progress of aerospace technology in the world, there are many cases of human going out of the earth into space, and space heroes are well-known. However, the physique and physical fitness of astronauts need to go through extremely strict selection and training. There are three main reasons for doing so. One is to ensure that astronauts are in space The second is to ensure that astronauts can quickly adapt to the impact of weightlessness on their bodies in space; the third is to enable astronauts to overcome the abnormal body function caused by gravity return to normal, including the “magic” phenomenon of body height increase! < / P > < p > although the physical fitness of every astronaut is one in a million, astronauts will still experience a disaster after returning to earth. So, what is the reason for this disaster? < / P > < p > we know that astronauts are not subject to gravity in space. In addition, the spaceship they are in is extremely narrow and does not have any movement conditions at all. Therefore, astronauts outside the earth must not only adapt to gravity, but also endure the boring space life without activity space. Over time, it will cause muscle atrophy and immunity decline of astronauts. < / P > < p > and in space, astronauts are in a state of weightlessness. Because the spine of a person can not feel the pressure, it will make the body more straight and straight. Therefore, astronauts who return to the earth often find that their height has increased, which is caused by the influence of gravity. < / P > < p > in the known condition of astronauts’ body height, the maximum range is as high as 9cm! < / P > < p > all countries in the world, all astronauts who have contributed to the cause of space are heroes. It is because of the exploration of these warriors that human space travel has made such rapid progress. I believe that in the future, countries can better protect astronauts while exploring the universe! New product launch
