Because there’s no gravity to pull the blood back down from their head. On earth, your heart works hard to pump blood up to your head, but in space to doesn’t have to fight against gravity, so blood that gets pumped to your head stays there. Which is why your face goes red and puffy if you’re upside down for extended periods of time, gravity is keeping the blood in your head.

It’s also why astronauts often have constantly blocked noses and sinus pressure, since gravity isn’t there to drain the mucus like it usually would.

The normal forces of gravity that are typically pulling things like hair and clothes down aren’t working on astronauts in microgravity, so those things float freely. They’re not actually being pulled “up” either, but the effect is unusual enough to us that we still notice and relate it to times we’ve seen people hanging upside down.
