What specific physiological changes in astronauts aboard the ISS are studied by NASA scientists?

Answer

Bone density loss, fluid shifts, immune system changes, and muscle atrophy.

When astronauts live long-term in space, scientists study their adaptation to microgravity and radiation, focusing intently on changes like bone density loss, muscle atrophy, fluid shifts within the body, and immune system response.
