What does zero gravity do to your body?

The muscles used to fight gravity –like those in the calves and spine, which maintain posture– can lose around 20 per cent of their mass if you don’t use them. Muscle mass can vanish at a rate as high as 5% a week.

Can humans live without gravity?

Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. … Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space.
