New space trip trio with female astronauts! So what if in space comes the menstrual period? Does life in space affect fertility?
A series of "women going to space on business" problems, accompanied by the Combination of Shenzhou 13 manned spacecraft and Long March 2F Yao 13 carrier rocket, were transferred to the launch area and once again appeared on the hot search.
According to the disclosed information, this time, the "Shenzhou XIII" crew stayed in space for 3 months longer than the "Shenzhou XII" crew, and there were female astronauts in the crew this time.
In addition, the "Tianzhou-3" cargo spacecraft, loaded with nearly 6 tons of supplies, including hygiene products and cosmetics for female astronauts, suddenly triggered a hot discussion about women's lives in space.
It just so happens that I am reading a book on space exploration, and I will talk about it from this point.
<h1 class="pgc-h-arrow-right" data-track="9" > first, what if female astronauts in space come to menstruation? </h1>
We ordinary people inevitably have some magical imaginations: for example, will women reverse the flow after weightless menstrual blood? Will the space environment affect the physiological cycle?
In fact, according to the known space exploration data of mankind, the female body in space, there is no obvious change, physiological period and menstrual volume are no difference.
I checked the scientific records of female astronauts in the United States — lucid female astronaut quipped: "Except for the disappearance of the calluses on my feet because I did not wear shoes, I did not find any change in my physical condition." The same claim was confirmed by American space shuttle astronaut Mike Mullen.
However, due to physiological characteristics, the physiological characteristics of blood flow in women are ultimately different from those of men. Therefore, women's endurance will be worse than men's.
Fortunately, the Chinese medicine community has developed a "space nourishing heart pill" for female astronauts. How is this Chinese medicine a good method?
The author is not a medical expert, naturally can not solve the composition of this pill, but according to the previous Chinese Astronaut Scientific Research and Training Center Astronaut Medical Supervision Medical Insurance Research Office Director Li Yongzhi's introduction: "space heart pills", has been on several days, and is a space meal essential, reduce blood oxygen concentration, improve anti-fatigue ability, both can regulate sleep, but also improve the endurance.
In other words, the space environment does not directly affect the physiological period, and drug reserves also regulate the negative impact of space life on the blood system.
In addition, fertility issues have also attracted widespread attention.
Du Heng, a researcher at the Space Center of the Chinese Academy of Sciences, once pointed out that there are a large number of high-energy charged particles in space, which will produce strong radiation, especially when encountering solar storms.
<h1 class="pgc-h-arrow-right" data-track="30" > then, the amount of radiation in space is very strong, will it affect female astronauts and lead to infertility?</h1>
Astronaut magazine gives the answer: in the low orbit of the Earth such as the International Space Station for manned space flights, radiation has little impact on the health of astronauts. Because there is a magnetic field around the Earth, it can capture most of the cosmic rays.
In addition, the spacesuit itself has a strong ability to resist radiation, and it is difficult to approach it in general radiation.
American astronauts have even joked: "Unless you fly to the sun, otherwise, if you want to be affected by the cosmic radiation of the space station, the difficulty coefficient is no lower than flying to the sun." ”
That is to say, in theory, "living in the sky for a while" does not seriously affect the fertility of female astronauts, and, in practice, the first female Svetlana Savitskaya who walked in space in 1984 gave birth to a baby boy a year and a half after returning to Earth from space.
Manned spaceflight, after all, can not be full of merit in one battle, human exploration of space, will not be limited to a temporary matter, can make human beings in space for a long time to survive, reproduction, is the ultimate mission of space exploration.
Therefore, the problem of life that we are worried about has long been carefully studied by scientists, in the final analysis, what is the significance of space that cannot live and reproduce for the future of mankind?
