They don’t hurt as much as you would expect. They are generally as light as possible and spinning with very little torque for energy efficiency. So even at max speed, it hurts less than bonking your head on something solid at walking speed, which is much more common. I am only 6’ 4", you don’t have to be as tall as you would think to “get to” experience this.
This strikes me as a mistake you can really only make once.

And you can easily just put your hand in front of a spinning fan and try for yourself. Don’t do it with metal fans though, only those wood ones.
