Why do my sinuses tend to swell shut when I sit or lay down, and open when I get up and walk around?

I’m not looking for suggestions for medication or homemade remedies. I have found an effective treatment for my sinus condition.

I’m just looking for a scientific/medical explanation for this phenomenon. Needless to say, I’m not a medical expert, but this just doesn’t make sense to me. Why in the world would walking have any effect whatsoever on my sinuses? But it does. Anyone know the answer?
It’s not just when I’m laying down, though. It happens when I SIT down for any extended period of time. As I sit through a class, my sinuses become more and more congested, so that by the end of the class, I cannot breathe through my nose at all. Then, in the time it takes me to walk from one building to another between classes, my sinuses open and I become completely clear. I sit down for my next class, and the cycle starts all over again.

When I’m sitting, my sinuses are oriented in the exact same position relative to the direction of gravity as they are when I’m standing or walking, so drainage cannot be the factor here.
