the first Conclusions They are for others worrying: astronauts sufferfor each month in orbit, Serious bone problems. as per search, Bone density decreases Between 1% and 2%, recovery is not achieved even one year after returning to Earth.
This way, stay in state of weightlessness It leads to a significant weakening of the bones. This was determined by a group of international professionals, detect report In the Journal of Scientific Reports.
“To study the effects, researchers measured the wrists and ankles of 17 astronauts before, during and after spaceflight. They found that their bones lose 1% to 2% of their density each month in orbit. The process is the equivalent of decades on Earth,” constribte RT.
According to Nature, it has been observed It was also found that bone recovery is slow. In fact, experts found that pimples from The astronauts did not recover Even a year after their return: Among those who spent a long time in orbit — in the sample there were people who had been there between four and six months — recovery was worse.
in this line, Interview with Agence France-PresseStephen Boyd, one of the specialists, compared the damage recorded to the Eiffel Tower, from which some rods were extracted, and warned that it would not be possible to return to its pre-flight state:
“When we get back on the floor, we thicken what’s left, but we’re not actually making new bars. However, exercise, especially deadlift, helps reduce the damage.”
Boyd believes that “the findings are important not only for current orbital flights, but also for potentially longer missions. In particular, they raise significant concerns about planned expeditions to Mars.”
“Will things get worse over time or not? We don’t know. We might get to a stable state after a while, or we might continue to lose bone. Let’s keep losing it until there’s nothing left,” Boyd said.
