It's not deadly for humans. Gravity doesn't stop your heart from pumping blood throughout your body. By that same logic your feet would always be pooling with blood when you're standing. At most you'll get headache from hanging upside-down for long periods of time.

We evolved to stop things like blood pooling in our feet.
Granted you'd have to be upside down for a really long period of time to die from it, but bad things can happen in shorter periods of time.
