I'm sorry my friend, I'm not a healer and I can't answer a specialized question that only a healer can answer.
Humans are great explorers, and our DNA drives us to keep exploring - we've landed on the Moon, we're about to go to Mars, and we'll probably go beyond the solar system.
There is no doubt that astronauts are among the healthiest people in the world because of the rigorous training, scrutiny, and isolation they undergo before going into space.
Despite these precautions, they sometimes get sick. For example, Fred Haise of Apollo 13 experienced a kidney infection during his dangerous mission.
Because space missions plan everything ahead of time on a strict schedule, it is difficult for sick astronauts to go directly to a doctor on Earth during a space mission.
And the environment and medical facilities in space are completely different from those on Earth, so when astronauts unexpectedly get sick and injured, they have to take some completely different treatment options than they would on Earth.
Medical Situation in Space
Each astronaut on a spacecraft has a specific mission, so everyone receives the intensive training required for that particular mission, and for medical emergencies, the crew medical officer is in charge.
The medical crew is trained not only in the usual first aid treatments, but also in other medical matters, such as suturing wounds and giving injections. In addition, all astronauts are trained in emergency resuscitation in the event of a heart attack.
The spacecraft's medical kits also contain many medical instruments and medicines. These kits are used to treat minor illnesses and injuries during the flight, and at least stabilize the patient for treatment back on Earth.
But as for medical emergencies, so far astronauts have only been able to get medical assistance remotely from space, and it's unlikely that a doctor would be able to travel to space to help treat them.
Even with the presence of a doctor, routine practices on Earth, such as setting up an IV, taking a blood sample, or even keeping a wound clean, are very difficult.
So what ailments can astronauts get rid of on their own?
Space-adapted diseases in zero gravity
Zero gravity alters many normal bodily functions, including the fact that fluids in the body float up and confuse the inner ear, making it impossible for them to tell up from down.
This leads to Space Adaptation Syndrome (SAS), a common condition similar to space sickness. Motion sickness, on the other hand, is the most commonly reported disorder, a subset of SAS, and it affects at least 67 to 75 percent of astronauts.
Astronauts' bodies take several days to adjust to weightlessness, during which time they may experience symptoms such as headaches and vomiting.
Although dealing with vomit is a nightmare, NASA has a good system for dealing with this problem.
Each astronaut carries special vomit bags with wipes and seals attached that can be used during launch or in orbit, and once they are used, the bags go in the trash.

Also, astronauts floating around in zero gravity are prone to bumping into things, and sometimes injuries are inevitable. When astronauts on the ISS want to check their wounds, they call a doctor on the ground and follow his or her instructions to treat them themselves.
Colds and Nasal Congestion
Because astronauts are quarantined before spaceflight, it is very unlikely that they will be exposed to pathogens in space.
But if an astronaut does get a cold or a stuffy nose, the snot doesn't empty in zero gravity, which can make astronauts feel more stuffy than on the ground.
To make matters worse, bacteria seem to thrive better in weightlessness, and according to Time, pathogens can form thicker cell walls in weightlessness, as well as cope better with antimicrobial agents.
Fortunately, even in space, a cold or flu goes away on its own, so astronauts just need to be patient.
Returning to Earth for Treatment
On the ISS, if something serious needs to be dealt with, astronauts can return to Earth via the Soyuz spacecraft that sent them into space.
Medical repatriation only happened once, in 1986, when Soviet cosmonaut Vladimir Vasyutin had to leave the Salyut-7 orbital laboratory with a prostate infection.
His return to Earth took about six hours, but fortunately it was not too serious, and today cosmonauts can land in less than three and a half hours.
Normally, returning to Earth for treatment is the only way for astronauts to be treated when they need to undergo surgery, which would be impossible in weightlessness, and the blood would flow right out of the wound, contaminating the entire cabin.

Finally: the future of space medicine
As humans go further into space, medical technology will need to become even more complex, and as we explore deeper into space, we may lose contact with Earth, and returning to Earth for treatment will be even more impossible.
Imagine what would happen if the crew doctor himself was injured or seriously ill and had to be treated by someone with no medical knowledge.
Perhaps artificial intelligence could help astronauts diagnose and treat illnesses, and also the use of remotely operated surgical robots would be a good option.
But there are a number of other technical and economic issues that we need to address before we can explore an exoplanet like Mars.
First, the most important thing is to strengthen physical exercise for astronauts, which is why astronauts are one in a million. The advantage of innate good health, combined with intensive physical exercise, is why astronauts generally don't get sick very often!
Then, if you are really sick, how do you do it? The doctors on the ground will guide the astronauts to take the medicines they are equipped with after the telemetry diagnosis, and they will need to be sent back to the ground for treatment of some acute or serious illnesses. For example, in 1985, a Soviet astronaut fell ill on the space station and was sent back to the ground on a Soyuz T14 spacecraft.
Hello, I'm glad to answer your question.
First of all, we need to go back to the roots of the problem! We all know that without hard training and a strong body, it is not possible to carry out a series of space work in weightlessness. So the physical fitness of astronauts is top notch in itself!
Then, the already strong body, plus the vacuum environment of space. So, there are rumors that in space, astronauts will not get sick. Because there is no bacteria in the vacuum environment.
In fact, in the face of this more rigorous question, I also looked up a lot of information, and the answer is that bacteria are still there. It's just that in this environment, the bacteria become less active. The cell structure has changed, from the "bad boy" into a "good boy", quietly do a beautiful man. But once they catch a chance, they're likely to explode in an instant. So there's still a chance that astronauts will get sick in space.
In addition, according to U.S. scientists in San Francisco, due to the weightlessness in space, will inhibit some of the immune genes in the body of the astronauts, so that they can not work. That's what we call an overall decline in immunity, so it's also one of the reasons for getting sick easily.
Well, synthesizing these influences. Astronauts are given nearly 100 medications that go up with the astronauts before they board the plane. If unfortunately they do get sick, they must return to land quickly to ensure life safety!
Also recall that in 2018, the Russian newspaper Kommersant published an article about a hole in the Russian Soyuz MS-09 spacecraft on the International Space Station, which it claimed was intentionally drilled by U.S. astronauts in the spacecraft to allow sick astronauts to be sent to the ground as soon as possible ......
In space, physically strong astronauts often get sick for a number of reasons. First, the weightless environment of space has become a haven for germs. On Earth, if someone sneezes, infectious particles will travel 1 to 2 meters in the air before falling to the ground. But in zero-gravity space, infectious particles float around. When they eventually fall somewhere, places like dashboards, equipment and food stations will not be spared. This makes it easy for infectious diseases to spread quickly in a cramped and enclosed capsule.
NASA prepares for emergencies as much as possible. Astronauts must undergo 40 hours of medical training before going into space. They must learn skills like tooth extraction and wound closure. NASA also equips astronauts with medical equipment such as defibrillators, first aid kits, books, ultrasounds, and saline solution.
But if something is untreatable, the astronaut's only option is to be an Earth doctor. Astronauts in space can send relevant images to doctors on the ground in order to fix the problem themselves with their help, but sometimes the diagnosis doesn't help with more serious problems.
If the problem is more serious and requires a return to Earth for treatment, the astronaut faces other risks. That's because astronauts are subjected to 4 to 5 G of gravity during the spacecraft's return to Earth, which is uncomfortable enough for a healthy person, let alone a sick one.
What if an astronaut gets sick in space?
This is a very serious and grave question.
Astronauts are undoubtedly a very healthy bunch, and the need for medical assistance during spaceflight is rare, but that doesn't completely rule out injuries and unforeseen illnesses in space. It is generally accepted that the risk of illness and injury exists when the flight is long enough, and in space, anything can happen. Therefore, it is necessary for the ISS and spacecraft to stock a certain amount of medicines.
What medical equipment will be on board the ISS and Soyuz spacecraft, and what medicines are carried on the flight?
Taking into account the fact that the ISS has a considerable number of metal structures and equipment with angular design, which the astronauts may come across in case of impact, antiseptics for use in case of minor breaks in the skin are configured, and the dressings are creams and bandages; sometimes the humidity in the Russian segment of the module is low, and therefore the members of the crew can feel discomfort in the eyes, and in order to get rid of these symptoms, in the medicine chests are equipped with drops for the eyes; it is known that. air conditioning on the ISS is constantly running, artificially maintaining the climate of the small environment, but crew members often induce myositis, and in view of this situation, medicines and warm ointments are prepared in advance. There are also medications used to address gastrointestinal related issues.
Nasal congestion may occur during the initial phase of spaceflight due to acclimatization, which is due to the weightlessness response of the body at that stage, with blood flowing from the legs to the head; also the increase in dust on the ISS can lead to allergies and nasal congestion, so nasal drops can be used to relieve similar symptoms. Crew members also usually take multivitamins containing trace elements. Some crew members complain of sleep discomfort because of the unsupportive feeling of sleeping, which may be the main cause of discomfort. In order to create a small, familiar sleeping environment for the crew members, sleeping bags with special straps, which have the feeling of the back being fixed to something, are prepared. If this does not help to sleep normally, then sleeping pills stocked on the space station are taken. In addition, in the medicine chest there are always drugs for regulating the heart, improving blood circulation, lowering blood pressure and eliminating cardiac arrhythmia. The crew hopes that most of the drugs will always be there in their original packaging.
There is no medium for viral influenza transmission on the ISS, because doctors at the Astronaut Training Center take fairly strict precautions against the astronauts before they fly into space, and crew members are in isolation, with contact with outsiders reduced to a minimum. Only people who showed no signs of contagion were allowed to contact crew members when necessary, and they were required to wear masks for meetings. All cargo is also specially handled before it reaches the space station to prevent the spread of infectious diseases.
Normally, each day begins with a short meeting with ground mission control. The short meeting focuses on discussing the day's activities. Each astronaut then begins work on his or her own schedule, which includes experiment operations, repair and maintenance tasks, meals, short breaks, and exercise. At the end of each day, the astronauts had another short meeting with Mission Control. There are two hours of exercise each day to keep them healthy.
The astronauts carry a full assortment of nearly 100 medications for possible illnesses. "Shenzhou" six spacecraft on the types of drugs involved in almost all clinical disciplines, including cardiovascular, respiratory, gastrointestinal, urinary, neurological, dermatological, five senses, oral, surgical, etc., the types of drugs are painkillers, stomach medicines, antidepressants, antidizziness drugs, anti-inflammatory drugs, stabilizers and so on dozens of kinds of drugs. "Shenzhou VII added five new medicines, including "space heart pills" and oral fast-acting tablets. In addition, the astronauts are also equipped with a daily medicine bag and emergency life-saving medicine bag, placed in advance in the return cabin.
Astronaut doctors also have to monitor the whole process of astronauts' flight in space in real time through the medical indicators transmitted back by the physiological undershirts that astronauts wear on their bodies. The spacecraft will real-time images of the astronauts' work and life, as well as their blood pressure, body temperature, respiration, electrocardiogram, four major basic physiological monitoring data transmitted to the ground command center. After the spacecraft is in orbit, the space doctors also have to open a special dialog channel. Since the astronauts' physical state and space feelings involve secrets, the dialog may use pre-designed code words. For example, symptoms, medication, feelings and so on may be changed into 10, 20 and other short digital, what each digital means, only the space doctor and astronauts know. This kind of call not only can grasp the astronaut's physical condition in time, the possible problems of prediction argument, but also can give in the silence of the special environment to live in the astronaut to psychological support.
All this, scientists have long thought, virus-free on the spacecraft, it is unlikely to develop.
Take medication.
Astronauts in space to get sick this chance should be very, very small, why do you say so? This is mainly due to the following considerations.
On the one hand, the selection of astronauts is very strict and harsh, astronauts not only have to have a healthy body, but also have a good psychological quality. In addition to the pilot's requirements for a comprehensive physical examination of the body, but also on the past history of attention to the presence or absence of hidden neurological - endocrine system function flocculation, a comprehensive and detailed examination of the cardiovascular system, vestibular function and visual system, etc.. It is also necessary to ascertain the astronaut's personality, emotional stability, and neurological state. These physical and psychological qualities before entering space to further do a comprehensive examination to ensure that the astronauts are physically unharmed.
On the other hand, the astronauts' space food is also carefully prepared, containing a variety of nutrients that the human body needs, so that "illness from the mouth" is absolutely impossible to happen.
As the saying goes, "Be careful what you wish for, but don't be afraid of what you might find", so don't worry if the astronauts get sick in space.
On the one hand, astronauts should be trained to master the necessary medical self-help capabilities, and the space station or spaceship is equipped with simple medical equipment and medical kits, like the movie "Mars Rescue" protagonist, the body is injured, but also self-help, stitching wounds, etc.
On the other hand, astronauts should be trained to master the necessary medical self-help capabilities.
On the other hand, after the astronauts entered the space, their body indicators will be the ground command center real-time monitoring, the astronauts will also be on the physical condition of the regular report, if the body of which the indicators are abnormal, the ground medical experts will be on the astronauts will put forward a reasonable proposal or response to the treatment techniques.
So, to sum up, the selection of astronauts, eating in space and so on will not let the astronauts have a big disease, astronauts in space in the chance of illness is very small, even if there is a small disease, by virtue of the astronauts of the ability as well as the ground command center of the effective first aid measures will also be able to solve, we do not need to worry about it.
I am a science enthusiast and I hope my understanding reaches your appreciation, thank you all!!!!
