With the maturity of manned space technology, astronauts and doctors in charge of astronauts' health need to think about an important question-what should astronauts do if they have gastrointestinal discomfort in space?
In the space environment, space is a very scarce resource, so the toilets in the spacecraft are also very limited. On the International Space Station, about 3-4 astronauts share a toilet. At the peak, even six astronauts share a toilet. If an astronaut has gastrointestinal discomfort, it will bring "pressure" to many astronauts.
Astronauts' "toilet time" is also carefully arranged: astronauts' space missions are often arranged and planned in advance; Working hours and meals in space will also be strictly controlled, and even the time for astronauts to go to the toilet will be planned.
Although the "toilet time" of astronauts will be planned in advance, astronauts often finish space work ahead of schedule. According to the feedback from astronauts, almost no one will abide by the "toilet time" arrangement. Because the time that astronauts need to use the toilet rarely overlaps, most astronauts can have enough time to occupy the toilet.
When astronauts first enter space, weightlessness will lead to changes in the position of human stomach. The weightless environment will also lead to the upward flow of blood and the accumulation of body fluids. In order to alleviate this situation, the brain will make the human body urinate.
Astronauts will be dehydrated in different degrees in the first few days in space, which will easily cause gastrointestinal problems and increase the use time of astronauts' toilets.
In order to reduce the utilization rate of toilets, astronauts will choose to wear diapers after entering space, which can directly solve some physiological problems.
Strict space plan to reduce accidents: when entering space, the astronauts' daily diet will be strictly controlled. Through diet control, on the one hand, it can ensure the daily nutritional intake of astronauts; On the other hand, it is to control the physiological problems of astronauts through diet.
Gastrointestinal problems are often the first problem that astronauts need to solve after entering space. After each manned launch mission is completed, NASA will ask relevant questions and give solutions in time.
If the astronauts have gastrointestinal problems, the ground control center will prescribe relevant prescriptions according to the current materials, thus helping the astronauts to quickly alleviate the gastrointestinal problems. In the relevant prescriptions of NASA, there is even tea that we are familiar with.
In order to avoid the time conflict of the space toilet, astronauts can choose to enema in advance before taking off to reduce the possibility of using the toilet.
Astronauts will also learn to use space toilets on the ground so that they can quickly solve their own physiological problems and provide convenience for other astronauts.
If the space toilet is really in short supply, then astronauts can only solve it by themselves with plastic bags. This method is very unreliable and there is a great "health risk".
When Apollo 1969 flew around the moon, a "floating event" occurred. The Apollo 10 document recorded the communication of astronauts, but all astronauts denied that they were the source of "floating objects", so the matter was dropped.
In 20 16, the gastrointestinal problems of astronauts were included in the space risk project announced by NASA.
Diarrhea and electrolyte imbalance caused by gastrointestinal problems will not only bring pressure to the use of space toilets, but also affect the health of astronauts themselves. If other astronauts can't use the space toilet normally, it will pose a potential health threat to the living environment of astronauts.
Although NASA believes that further improving the "water absorption" of spacesuits is a solution, this solution will undoubtedly reduce the comfort of astronauts in space missions.
Summary: Space life is a very complicated matter, and using toilets alone is full of potential risks.
However, the essence of space toilet pressure is that human space technology is not yet mature. If humans can launch spacecraft with larger space, they can easily solve related problems. If humans can create a spaceship that simulates gravity, they can avoid the physical discomfort of astronauts such as dehydration.
Astronauts are also human beings, and the most suitable environment for human survival is the earth environment. If humans can bring the earth's environment into space, we can easily achieve a long-term space journey!
