Red Blood Cells Die Faster In Space

In a new study about space missions, it has been told that space missions start destroying red blood cells in the human body more rapidly. This can be a big problem, which can cause a lot of trouble not only for long-distance astronauts, but also for those travelling to space for tourism who are already suffering from anaemia.

The health of astronauts is one of the major challenges in preparation for long space missions. But now astronauts have no less problems on short trips. Now that even ordinary citizens will start going to space through space tourism, then health in space will face new challenges, it is a sure thing. Scientists will now have to solve a major health problem in space travel. Due to going into space, the red blood cells in the blood of the passengers start decreasing. In such a situation, a challenge like anaemia is going to be a big need.


Maintaining Red Blood Cells

Many health-related problems were already a challenge for space travel. Now according to new research, maintaining sufficient amounts of red blood cells in astronauts for long journeys will also be a problem that will be very important to solve. Even space tourists may have to stay indoors if they are at risk of anaemia or lack of red blood cells.


This was considered a temporary problem

It is noteworthy that space anaemia is not a new thing. But until now it was believed to be a temporary problem. It was said in the study that this problem is cured in 15 days. The loss of red blood cells during space travel occurs by replacing the fluid accumulated in the astronauts’ bodies due to weightlessness and by returning to gravity.

Guy Trudell of the University of Ottawa, who has studied 14 astronauts from the Canadian Space Agency, says that anaemia is actually a basic effect of going to space. As long as you’re in space you’re eliminating more blood cells and then making them when you return.


Normally a human body kills 2 million red blood cells in a second and replaces them. Trudell’s team has found that astronauts’ bodies can kill 30 million red blood cells per second in six-month missions. Trudell says that we thought we knew about space anaemia. But we didn’t know.


What Happens In Space

In fact, the astronauts used to make extra cells to replace the red blood cells that were lost earlier. But Trudell has raised the question of how long the human body will continue to produce 50 percent more red blood cells. In such a situation, both the travel time and the capacity of the human body can affect it.


  The effect of gravity on red blood cells (RBC) becomes another problem factor.  Trudell believes that this could become a problem in the two-year journey to Mars. He said that if you are going to Mars then you will not be able to keep it because for this all the extra red blood cells have to be made and you can get into serious problems in such a situation.
