Microgravity and Human Health: Risks, Benefits, and Spaceflight Hazards

What does space do to the body—and how can it advance medicine? We break down microgravity’s risks (fluid shifts/SANS, bone loss, muscle atrophy, cardiovascular deconditioning, immune dysregulation, radiation exposure) , then explore benefits for biotech: protein crystallization, stem-cell growth, organoids/tissue engineering, and drug discovery. Clear takeaways for space medicine and Earth health. Educational only; not medical advice.
