Spaceflight makes the body kill red blood cells and it doesn’t get better after landing

Space anemia is more serious than we thought.

Being in space causes the human body to destroy about 50% more red blood cells, leading to a potentially dangerous condition known as anemia. The effects persist even after astronauts return to Earth, according to a new study.

The study, led by researchers at the Ottawa Hospital and the University of Ottawa in Ontario, Canada, analyzed breath and blood samples of 14 astronauts before, during, and after their six-month missions aboard the International Space Station. The researchers found that the astronaut’s bodies destroyed about 54% more red blood cells than they would on Earth.
