Astronaut is causing an extremely strange phenomenon in the blood of astronauts

The larger the length of the journey, the more difficult it becomes to control. After all, what did the astronauts suffer?

Space travel is not a simple thing. To be selected, astronauts must go through an extremely rigorous preparation process, with rigorous standards.

But even so, getting into a completely different environment than the ground is likely to cause significant changes to our bodies. In it, there is a strange phenomenon that occurs with blood , published in a recent NASA study.

After traveling, the ability of blood to transport and absorb oxygen during reduced mobility.

Specifically, experts from NASA and Kansas State University (KSU) used data from 9 male and female astronauts, who have at least 6 months on duty on the International Space Station (ISS). This data includes training before and after space travel.

As a result, the team found that after traveling, the ability of blood to transport and absorb oxygen when motion decreased significantly before leaving the ground. This means that astronauts' mobility is also reduced, particularly from 30% to 50%.

"This is a frightening reduction," said Carl Ade from KSU University, the research director. "When the cardiovascular function drops, your mobility also decreases. You can't do the" stressful "exercises anymore."

"Previous research has suggested that this occurs because the function of the heart decreases, but the data show that it occurs in both capillaries, at the microcirculation level."

This is a problem that is not easily solved. According to experts, we need to understand exactly why the amount of oxygen absorbed decreases, and this is currently not possible. Some solutions, such as strengthening exercise or medicine, may also be used, but it is only a temporary solution to help astronauts resist side effects from the universe.

In addition, experts say this study will help humankind better understand how blood vessels work , especially in the elderly and patients with heart attacks.

Research is important for future Mars travel.

In addition, this is considered an important study, serving long-term travel tasks. As for Mars, for example, astronauts must spend at least 8 months in a gravityless environment to reach the Red planet. If mobility decreases, it will be a big problem.

Not to mention, astronauts face many other problems, such as reduced bone and muscle density, inversely proportional to the length of the journey.

The point here is not for us to be discouraged, but science still has many problems to be done before completing the project to bring people to conquer Mars.
