Redistribution of body fluids in
zero-g makes your face puffy. Your eyeballs
distort, blurring vision.
As your heart no longer needs to pump
blood up against gravity in zero-g,
it weakens and deteriorates.
Conditions aboard spacecraft can
lead to insomnia, loss of appetite,
anxiety and depression
Long-term exposure to cosmic rays may also
impair brain function, which could be critical
in an emergency situation

YOUR BODY
IN SPACE
Your inner ear can’t work in microgravity,
which can cause dizziness and space
sickness.
Without gravity, your skeleton loses calcium
to become brittle and weak, like with
osteoporosis.
