Head rush?: What you describe is called "orthostatic or postural hypotension," a sudden, brief decrease in blood pressure that can occur as you change from sitting or lying down to standing upright. If the heart ant and blood vessels don't compensate quickly enough for the change in position to maintain consistent blood flow to the brain, you will experience dizziness or lightheadedness., a "head rush."
