Question

How does microgravity affect the human body? A: QUICK ANSWER

Answer 1

Microgravity usually makes your body very nauseous, and due to it, your bones, especially your spine, enlarges by some percent. (Not all effects)

Answer 2

Many different ways, primarily through bone and muscle loss. The lack of pressure on bones causes the body to reabsorb calcium from them, weakening them and potentially causing kidney stones.
