Scientists have discovered new evidence for why astronauts get anemic after returning to Earth following space travel. According to Canadian specialists, space destroys 50 percent more red blood cells than Earth does, and this happens through the journey. Their discoveries, on the other hand, may be valuable to other bedridden people around the planet who are experiencing the same problem. Since the first expeditions returned to Earth, scientists have known about “space anemia,” but the cause has remained unexplained. A small University of Ottawa study of 14 astronauts who spent six months on the International Space Station, including Britain’s Tim Peake, has revealed more. The researchers were able to determine red blood cell loss using blood and breath samples collected during their visits. These cells are necessary for life because they transport oxygen from the lungs to other parts of the body.
