Do you know why astronauts face bone density loss in space? The absence of gravity reduces the stress on their bones, leading to bone density reduction. Bones are dynamic structures that constantly reshape in response to stress.

To build bone mass, weight-bearing exercises like walking, jogging, volleyball, and basketball are essential. In space, astronauts use restraints on a treadmill to simulate these exercises, but this only slows bone loss, not preventing it completely.
