The Impact of Space Travel on the Human Body: Insights on Bone, Blood, and Immune System
A new study of International Space Station (ISS) astronauts suggests that fatty tissue inside bones helps replenish red blood cells and rebuild bone lost during space travel. The study examined 14 astronauts who spent at least six months on the ISS and found that the body uses fat in the bone marrow to replace red blood cells and increase bone density. This knowledge could lead to treatments for aging populations and individuals on Earth who are bedridden due to medical conditions. Understanding how to prevent anemia in space is crucial for future missions to the moon and Mars.
