Space sickness causes

Diseases caused by long-term weight loss. Just solve the problem of weightlessness.

Huang Weifen, chief designer of the astronaut system of China's manned space project, known as the "female head of astronauts", said in an interview, "Don't worry too much about injuries, becauseThe space station is equipped with more than 100 kinds of medicines and medical equipment, and the astronauts have also undergone intensive medical skills training, and their self-rescue ability has been greatly improved, and they can deal with basic diseases and trauma

According to reports, in December 2019, the astronaut system completed the crew selection of the Shenzhou 12 to Shenzhou 15 missions. The selection revolves around a comprehensive examination and evaluation of the mind, body, psychology, knowledge and skills.

In the selection process, we comprehensively consider factors such as flight experience, the matching of the requirements of the out-of-cabin activities with their respective missions, the combination of new and old age, and psychological compatibility to determine the crew. We have stepped up the screening of potential clinical diseases to ensure that the physical fitness and health of astronauts can meet the requirements of the mission. Huang Weifen said that at the same time, the astronaut system also evaluates the emotional stability and crisis handling ability of the astronauts in the crew according to the characteristics of long-term flight missions, and assesses their psychological ability.

She said that at present, astronauts have the ability to perform flight missions in terms of mind, body, psychology, knowledge reserve and operational skills, and are ready for flight missions.

Further reading - astronauts' work and rest time are synchronized with heaven and earth

Chief designer Huang Weifen introduced that the work and rest system of astronauts in orbit is synchronized with heaven and earth. Because during long-term flight, the ground staff must be on duty in the flight control, so the work and rest system of the astronauts in orbit is synchronized with the ground in heaven and earth.

At 8 o'clock in the morning, the astronauts in orbit have to communicate with the ground about today's work plan. From 8 p.m. to 9 p.m., we will communicate again about the completion of today's work and the adjustment of the next day's work.

Astronauts will strictly check their physical condition and disease history before going to heaven, and they are not allowed to go to heaven if they have a serious medical history. In addition, the food eaten by the astronauts is also carefully selected, and there will be no problems.

But even then, it cannot be ruled out that astronauts will suddenly get sick in space. February 2008.

Atlantis.

Space Shuttle.

with the International Space Station.

After a smooth docking, NASA.

Announced, it was scheduled for the next day.

Spacewalk. It was postponed by a day due to "health problems with one of the astronauts".

Therefore, astronauts will prepare several contingency plans to activate when astronauts are sick. In addition to the necessary disease prevention and treatment plan, the medical supervision and medical insurance system will also equip the spacecraft with spaceflight.

Medicine Chest, by. Astronauts take the spacecraft.

Aerospace doctors should also monitor the whole process of astronauts flying in space in real time through the medical indicators transmitted back by the physiological vests worn by astronauts. The spacecraft will transmit the images of the astronauts' work and life in real time, as well as their four basic physiological monitoring data of blood pressure, body temperature, respiration, and electrocardiogram to the ground command center.

In addition, after the spacecraft flies in orbit, the astronaut doctor has to open a special dialogue channel. Due to the confidentiality of the astronauts' physical state and space sensations, the conversation may be in a pre-designed code language. For example, symptoms, medications, feelings, etc., may be transformed into short numbers such as what each number represents, and only astronauts and astronauts know.

It is understood that this kind of call can not only grasp the physical condition of the astronauts in time and conduct the best demonstration of possible problems, but also provide psychological support to the astronauts living in a quiet special environment.

3. If astronauts suffer a little illness in space, then most of them will choose to endure it slowly and carry it with their bodies. In fact, for us, the physical fitness requirements of astronauts are harsh, because of this, the physical fitness of astronauts is generally relatively good, so under normal circumstances, they will not get sick, and ordinary minor illnesses also need to be carried by themselves, which is why the perseverance of astronauts is needed to support themselves.

Most of the time astronauts don't get sick easily in space, which is why there is no such precedent, but imagine that if you do get sick in space, then most of the time you will choose normal**, and if it is indeed a concurrent emergency, you will also call the headquarters and return to Earth with the approval of the headquarters**.

There are standing medicines in the space station, and if you become seriously ill in the spacecraft, the ship will stop its mission and return to Earth, and the station will send it back on the next rotation.

Astronauts will carry some emergency medicines with them when they go into space, and they can take medicine when they are sick.

Can astronauts get sick in space? What should I do if I get sick?

Personnel from the ground command should be contacted urgently, and then the follow-up should be directed by the ground command.

The astronauts were carrying emergency medication. If there is no symptomatic medication, the average astronaut will spend a very short time in space after returning to Earth**. The physical condition of astronauts is incomparable to that of ordinary people, and the quality of their physical meditation and meditation is better than that of ordinary people after many years of training on the earth.

Before going to space, they need to undergo various tests and examinations on their bodies, and if there are underlying diseases that affect the aerospace requirements, they will be replaced. It is important to make sure that all the indicators of the body are normal before going to heaven. After going into space, in a vacuum.

The capsule is strictly disinfected and free of germs.

Astronauts who live in space for a few months may also get sick, or they may not be sick at all, because there is no living environment for the virus, and only those who are sick can get sick if they bring the virus into space, and they will not be able to reproduce effectively at all under the closed conditions of space. Astronauts are selected from those who serve in the army, they do not have a strong body, they are first-class people in training, even if they accidentally carry the virus to the sky, they will disappear naturally under the action of natural conditions.

Therefore, our astronauts will not get sick. However, after living on the earth for so many years, no one dares to say that he has no diseases and disasters in this life, and the space station is still prepared with medicines for some common diseases, or for frequent diseases. Let's pray together with us astronauts!

Chinese astronauts take good care.

If there is a situation that endangers the life and health of astronauts in space, the later space launch mission will be coordinated and an emergency rescue spacecraft will be launched to bring back the astronauts. After exhausting all means to no avail, the relevant mission will be terminated, after all, human life is at stake. Once an astronaut falls ill in space, there must be corresponding measures, because before carrying out space operations, the relevant parties must take into account all possible situations and make emergency measures, so as not to panic.

Getting sick in space is the same as getting sick on Earth, there is no difference.

There will be no such situation, every astronaut will strictly check the physical condition when he goes to heaven, and if there are some diseases, he cannot go to heaven or grass, so this situation will not happen.

Because there are daily medicines in the space capsule, if the astronauts get sick in space, Wang Ying can use the medicine or instruments of the space capsule to perform the sleepy posture**.

If it is a relatively simple cold or other disease, you can directly take some cold medicine to prevent it. If it is a sudden illness, it must be directly approved by the General Curved Ruler Department of the National Aerospace Burial Bureau, and then return to Earth for treatment.

Generally speaking, astronauts must undergo a strict examination of their physical fitness before landing in space, and it is impossible to get sick.

Can astronauts get sick in space? What should I do if I get sick?

It is inevitable that people will get sick in space, and weightlessness will bring a lot of trouble to healing in space. First of all, it is difficult to diagnose, weightlessness makes the chest and head congested, the appearance changes, and it is difficult to accurately observe and auscultate. The Soviet Union once performed open abdominal surgery on rabbits in a brief weightless environment where the plane flew in a parabolic flight, and it was initially proved that surgery could be performed in a weightless environment.

But that's still a long way from performing surgery on people in space. Because in the small space of a spacecraft, it is impossible to build a large operating room and operating table; At the same time, human immunity has been reduced in a weightless environment, how risky is the operation? These need to be thoroughly studied and conditions created to solve them.

At present, the general impact of weightlessness and other space environments on astronauts is dealt with in accordance with predetermined health measures, the most important of which is the strengthening of physical exercise; For occasional minor ailments, the ground doctor can diagnose them through telemetry and instruct the astronauts to take the equipped medicines. For acute and serious illness, it is necessary to return to the ground**. For example, in November 1985, Soviet cosmonaut V. Vashutin fell ill on the Salyut 7 space station and was sent back to the ground on the Soyuz T14 spacecraft.

Sending sick astronauts back to the surface can be life-threatening for acutely ill patients with lost precious time, which is the biggest problem. Another problem is the high cost, which typically costs $2.3 billion. Therefore, the solution in the future should be to build hospitals in space to treat space patients, and until then, they should be dealt with separately according to the situation.

On February 8, 1987, Soviet cosmonauts A. Lavekin and Yuu Romanenko entered the "Mir" space station on the SoyuzTM2 spacecraft and were expected to live in space for one year, but Ravegin fell ill halfway, and the ground command center decided to let him return to the ground on July 30 of that year with two other short-term flight astronauts**. Later, Romanenko also felt tired, but the ground command center did not let him return to the ground, but gradually reduced his working hours, from the original hours, to hours, until finally stopped all work, so that he set a record of 326 consecutive days in space.

They are generally in good physical condition and do not get sick easily.

Under normal circumstances, it is not the general physical fitness that cannot be an astronaut, and astronauts will suffer from osteoporosis and lose their life if they stay in space for a long time.

If you get sick in space, it is of course the most inconvenient, and the growth of bacteria can be more serious.

Astronauts are in good physical condition, and they generally don't get sick, and they know how to save themselves even when they are sick.

Because astronauts stay in space for too long and are prone to osteoporosis.

It's very troublesome, and bacteria can also mutate uncontrollably in space.

It is very likely that Yuan Yuan will get sick in space. will die directly.

Being sick may make you more uncomfortable with weightlessness.

According to scientists, getting sick in space is worse than getting sick on Earth, because the environment and gravity in space make your immune system more fragile and difficult to fight off infections.

They're relatively physically good. Probably not so.

I don't know, but in general, astronauts are in good physical condition.

If you feel sick when you're having a hard time, think of astronauts in space! According to research, a small problem on Earth can pose a big threat in space.

What happens when an astronaut gets sick in space?

During the 30 years of NASA's space shuttle program, Dr. Leonard Mermel, an infectious disease expert at Brown University, tracked the health records of 742 astronauts on 106 space flights. He found that nearly 30 astronauts were suffering from infectious diseases, mainly fever and chills, as well as some fungal and ** infections, flu, etc. So it is clear that astronauts in space do get sick, and quite a few.

Why do astronauts in space get sick?

In space, astronauts who are otherwise fit often fall ill for many reasons. First of all, the weightless environment of space has become a paradise for bacteria. On Earth, if someone sneezes, infectious particles fall to the ground after 1 to 2 meters in the air.

But in zero-gravity space, infectious particles will be floating everywhere. And when they end up somewhere, places like dashboards, equipment, and food stations won't be immune. In this way, infectious diseases can easily spread quickly in a cramped and confined space capsule.

In addition to this, astronauts' immune systems become worse in space, which can also cause them to get sick. Once there is a wound, it takes a long time to heal and the immune system is not able to fight the infection strongly.

How do astronauts in space cope with illness?

In response, NASA is preparing for some contingencies as much as possible. Astronauts undergo 40 hours of medical training before going to space, where they learn skills such as extracting teeth and stitching up wounds. NASA also equips astronauts with medical equipment such as defibrillators, first-aid kits, books, ultrasounds, and saline.

But if something happens that can't be **, then the only option for astronauts is a doctor on Earth. Astronauts in space can send images to doctors on the ground, who can help them solve the problem on their own, but sometimes a diagnosis doesn't help with a more serious problem.

If the problem is more serious and it needs to be returned to Earth for **, then the astronauts will face other risks. Because in the process of returning the spacecraft to Earth, astronauts need to withstand 4 to 5 g of gravity, which in itself is already uncomfortable for healthy people, let alone sick people.

As the length of space flight lengthens in the future, new technologies need to be developed to deal with the problem of astronauts getting sick, making space** simpler. One of them is the development of a robotic surgeon so that many problems can be solved in space.

So, if you feel sick when you feel bad, then imagine how far you are from the nearest hospital when you're in outer space!
