Due to differences in living conditions in space and on Earth, adapting to life on the surface after living on the International Space Station (ISS) can be a more difficult task than it seems.
To demonstrate one of the side effects that astronauts suffer upon returning to Earth, Drew Feustel posted a video of his recovery after spending 197 days at the ISS.
It is the difficulty of walking straight with your eyes closed and the need to train to do it again. It is known that while astronauts are in space, they spend about two hours a day training to maintain muscle tone and bone mass.
But even these trainings do not guarantee that when they return to Earth they can walk normally. Precisely for this reason, astronauts go through a series of rigorous physical and medical tests upon their return.
Thanks to the information obtained, scientists can study the effects of a prolonged stay in space in the human body.
It is a very important knowledge in the face of future long-term space missions, such as the trip to Mars.
