According to what I have read by Win, one needs to sit or swim at the bottom of the pool.Immersing one's face in the sink, say, won't trigger the body's powerfulresponses which occur when one is fully submerged.
I posted this a few messages up here. Since your head is on top of your body, it's right to assume that your whole body must be immersed. Also because you function as a whole, I assume the water pressure should be the same in every part of your body.
You can't chop off your head and then put it back on your body, right?
The only way to have your head depper than your body would be by raising your feet, that would provoke two bad things:
1) Water will enter your nose more easily, unless you use a nose-peg.
2) Blood will concentrate in your head, I don't know much about anatomy, but you don't want to do that for a straight hour.
So don't do it.
