"Space Travel's Impact on Astronauts' Red Blood Cells Revealed"

A 2022 study has revealed that astronauts experience a significant loss of red blood cells during space missions, with their bodies destroying about 54 percent more red blood cells than normal. This phenomenon, known as 'space anemia', continues throughout the duration of the mission and can lead to higher-than-normal circulation of iron serum in the blood, potentially resulting in anemia. While red blood cell levels return to normal a few months after landing, astronauts' bodies continue to destroy 30 percent more red blood cells than before their space trip, posing potential health risks. Adjustments to astronaut diets may be necessary to account for increased red blood cell production and prevent adverse effects upon returning to Earth.
