‘As long as you are in space, you are destroying more blood cells than you are making’: A new study suggests anemia could pose a challenge for space missions
Jan 14 - The next "giant leap" for humans may be a trip to Mars, but having enough oxygen-carrying red blood cells for the journey might present a challenge, new research suggests.
In fact, anemia is "a primary effect of going to space," said Dr. Guy Trudel of the University of Ottawa, who led a study of 14 astronauts funded by the Canadian Space Agency. "As long as you are in space, you are destroying more blood cells" than you are making." Having fewer red blood cells in space is not a problem when your body is weightless, he added. But after landing on Earth, and potentially on other planets, anemia could affect astronauts' energy, endurance and strength.
