In brief: Blood flow

When you stand up, there can be a temporary decreased in blood flow to the brain.
The blood vessels have to tighten up a little bit, and the heart has to pump a little harder. Getting dizzy or light-headed when standing up is called orthostatic hypotension. The first step to try to make this better is to drink plenty of fluids.
