When astronauts return from space missions, will their bodies be affected by the space environment?

The answer is yes, after astronauts return from space missions, their bodies will be subject to certain changes to a greater or lesser extent. In space, the impact of harsh environments on astronauts' bodies is enormous. The main effects of this are:

Space diseases, bacterial invasion, space radiation, space toxic dust, etc., astronauts' long-term stay in space will also cause great psychological impacts. Astronauts are isolated from family and friends in the small space of the spacecraft, and if they are not psychologically strong, they are likely to lead to mood swings, mental anxiety and fear, etc.

I think it will indeed change, because the environment in space is relatively harsh, and in a weightless environment, various organs of the body may not be able to adapt to it, which may lead to the appearance of space sickness.

I think it will be somewhat affected by the space environment, because the living conditions of the space environment, the distance between the air and the earth are different in all aspects.

After astronauts return from space, the compression of the bones will be significantly reduced, and the muscles will also have some degeneration, and the density of the bones will also decrease. I believe that everyone should have a dream of being an astronaut when they are young, but it is very difficult to become an astronaut, both physically and psychologically. Therefore, every astronaut is very respectable, because after they live in space for a long time and then return to Earth, there will definitely be some changes in their bodies, which will affect their normal life.

The environment in space is different from that of the Earth, whether it is air pressure, air temperature or gravity, it is very different from that on Earth, and in space, astronauts also have to face very strong radiation. Because there is no gravity of the earth in space, there is no way to support the astronauts' bodies, so their movement will be limited to a certain extent. And there will be very strong radiation in space, even if the astronauts wear very heavy spacesuits, there is no way to completely isolate them.

Because there is no gravity of the earth in space, the compression of the bones of the body will be significantly reduced, and the height of the astronauts will become taller, but after returning to the normal life of the earth for a period of time, the density of the bones will return. Because there is gravity on the earth, the muscles will be in a sinking state, and people will have to overcome the gravitational pull of the earth all the time if they want to exercise normally. But in space, because there is no gravity and gravity, human muscles are also in a relaxed state.

If you stay in space for a long time, it is easy to cause muscle atrophy. Therefore, these astronauts will also be equipped with fitness equipment in space, and if they do not carry out continuous training, it is easy to cause muscle degeneration. Moreover, it is easy to cause a series of cardiovascular problems in space, because there is no tissue ability for the body's blood in space, so the blood will flow to the surrounding of the body, and the center of gravity of the body will also be upward, which can easily cause problems such as varicose veins and facial swelling.

There will be severe swelling in the body, muscle atrophy will reach level 4, and then it will be difficult to lift the legs, and the pressure on the bones will become less and less, but in 20 days, it is possible to grow 5 cm taller, and many people will need to lift it out when leaving the cabin.

Your body may be weightless, after all, you may not be able to adapt to the gravity for a while, or you may not be able to operate your own behavior or walk normally, and you can return to normal after a period of relief.

The compressive force of the bones is significantly reduced, the muscles do not degenerate to varying degrees, the bone density decreases, the DNA inside is likely to mutate, and the weight and height will change.

When they stepped out of the cabin, they were actually supported by the staff to prevent them from falling and injuring themselves. After that, they will also need to undergo a 14-day medical quarantine. You might think it's because of the recent outbreak, but that's not the case, as astronauts are largely quarantined when they return to Earth.

When it comes to quarantine, I'm sure everyone is familiar with it. Especially in the shadow of the last two years, we have been more or less isolated. But the isolation of astronauts is not of the same nature.

In addition to the lack of oxygen and water needed for life, the radiation environment in space is also a factor affecting living things. You've probably all heard of space breeding, which basically exposes seeds to high radiation in space, or microgravity or something, causing genetic mutations. Can a human body last longer in space?

A Mars exploration mission can take two or three years, and to date, most space expeditions have lasted six months or less.

How long-term missions beyond Earth orbit can pose potential risks to astronauts' bodies. The muscles are in a state of tension under the action of gravity, and in the process of people's actions, they will always overcome the gravity of the earth to do work, which is equivalent to all the time"Exercise"。But in the space environment, there is generally no need to overcome gravity to do work, and the muscles are in a relaxed state for a long time"Atrophy"The effect will become more pronounced the longer it stays in space.

However, in the microgravity environment of space, the body of the Yufeng clan hardly needs to exert force, and the bones will not be squeezed, so they will no longer grow, and the bone will even be lost.

The above is a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

They usually need to go through a long period of exercise to get familiar with the gravitational pull of the earth, and due to their long-term exposure to microgravity, their body muscles will be seriously degenerated, and due to the long-term consumption of specific food, their gastrointestinal function is very weak, unable to accept our normal food, which requires a certain amount of time to get acquainted.

Astronauts are unprepared to return from closed space and their athletic ability will decrease, because space is a gravitational environment, and long-term combustion in space will reduce motor function a lot, and the oxygen content of the body will also decrease.

The main reason is that the ability to move will be greatly reduced, because they are in a state of weightlessness for a long time, because in the environment of microgravity, it is difficult for oxygen to reach the muscles of the human body.
