Since the construction of the Chinese space station, astronauts have been conducting various medical experiments in space. What happens to astronauts' bodies in space? And how do they do medical research? Hear what the experts have to say.
【1】What will happen to the human body in space?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
With the different time of entering the orbit, his physiological response is different, and the first entry into orbit is mainly based on the reaction of the nervous system, the distribution of body fluid head and so on. Then with the extension of time, there are cardiovascular problems, a little longer muscle atrophy problems, a longer bone loss problem, bone loss continues to accompany his flight cycle continues to occur, then there are also what immune system problems in between, as well as oxidative stress problems, as well as the body's comprehensive adaptation to endocrine problems and so on. There will be some changes in taste and smell.
[2] Is there any difference between the physical reactions of female and male astronauts?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
For standing endurance, there is still a slight difference between women and men in terms of its regulation. It's whether you can get up as quickly as you get back on Earth. After returning to Earth after weightlessness, his blood pressure regulation system, the cardiovascular regulatory system changed. In general, standing endurance is reduced, but some people may be shorter and recover quickly, and some will take a relatively long time.
[3] Do astronauts change their tastes in space?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
Because the change of taste and smell is actually different from person to person, from the current international reports and some of our experimental data, everyone's change characteristics are different, some people may like acid when they first go up, and they don't like it in the later stage. But this one will soon come back to Earth.
Our recipe design first to ensure its nutrient balance, and second to adapt to some of the effects of space flight on the human body, so we will fully consider these effects and changes, in the diversity of recipes, the personalization of recipes and the category of recipes.
What medical experiments will astronauts do in space?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
On the one hand, we have to collect our own body fluids, blood, saliva, urine, which are all very precious and valuable experimental samples for us.
The second we have some physiological research, from this structure to function, such as our ultrasound, we go to observe his optic nerve, observe his arteriovenous vascular changes, observe the structure of his muscles, and a category of we carry out a variety of electrophysiological tests, such as brain electrical electricity, and another is some of his gait and so on.
【5】How do astronauts collect body fluids in space?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
For example, anti-floating, anti-leakage, anti-bubble when collecting liquid, these will have a special design, which is also a feature of space experiments and the ground.
Will space experiments involve traditional medicine?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
For example, when we do acupressure point stimulation clothing, we are combined with some clinical patients to do experiments. We are mainly aimed at identifying the impact of the aerospace environment on the human body from the theory of traditional Chinese medicine, mainly for the cardiovascular problems of bone muscles, we combine the acupuncture points of traditional Chinese medicine and stimulate different acupuncture points to achieve his adaptation to this weightless environment and the regulation of the body.
[7] Is aerospace medical research helpful for the moon landing?
【During the same period】Li Yinghui, deputy chief designer of astronaut system
The system theory and method platform we have established on the space station not only to solve the health and human factors problems of our human flight in low Earth orbit, but also to carry out some theoretical and technical reserves for us in the future of lunar exploration, for example, for human capabilities, then his adaptation to the gravitational environment, we are now in the space station is a microgravity state, is a weightless state, to the moon is a low gravity state, then in microgravity and low gravity state, its adaptation characteristics, The construction of adaptation laws and adaptation models, then we can achieve it on the space station, so this is an important basis for the moon to make a deep space exploration for us.
