Our bodies have evolved to push blood from our feet back up the heart, against the force of gravity. whenever you sit down or lie down, your body finds it easier to pump blood to your heart and head/brain. as soon as you stand up, the blood drains from your head back down to your feet and your body has to start forcing blood against gravity..
so if the reverse is true, matt when you sit down the blood gets to your brain easier, increasing it's effects
