After the astronauts return to the ground, they must carry out relevant medical examinations, that is, conduct a comprehensive health examination of the astronauts' bodies. After returning to the training base, it is necessary to observe for a period of time and conduct a more detailed and systematic physical examination and health assessment. Because there are many and complicated inspection items, astronauts are not allowed to see other people at this stage, especially those who perform tasks under special conditions, because space is unknown to human beings, and the effects of different space environments on astronauts are also unknown, such as decreased standing endurance, decreased balance function, muscle atrophy and so on, which need special attention.
Moreover, astronauts live in space for a long time, and a series of radiation problems are likely to affect the body. Moreover, after living in space for a long time, I often feel exhausted when I return to the ground, let alone being interviewed. There are too many unknowns in space, and radiation in space may mutate bacteria and viruses. It will eventually lead to serious consequences, and medical isolation is necessary and necessary.
