What Would Happen to the Human Body in Zero Gravity?

💡 The Answer

• Astronauts experience muscle atrophy and bone density loss during prolonged microgravity.
• Bodily fluids shift upward, causing facial puffiness and reduced leg volume.
• The spine expands, temporarily increasing height by several centimeters.
• Without gravity, the sense of balance is disrupted, leading to space motion sickness.
