During missions on the International Space Station, astronauts’ bodies go through a wide array of changes due to lack of gravity – everything from vision to cardiovascular health to bone density is affected.
Though astronauts exercise and take supplements to mitigate some of these effects, understanding more about deconditioning in microgravity could allow physicians to design better treatments. This wouldn’t just be useful for spacefarers; it could also improve treatment strategies for common health conditions here on Earth.
