Probably dehydration: A common symptom of dehydration is dizziness with standing. This is because when you are dehydrated, your blood pressure tends to be low and when you stand up, the blood pressure drops as the blood in your head falls (due to gravity) down back towards your heart. As a result, this can make you feel temporarily dizzy or lightheaded, which may or may not be accompanied by ringing in the ears.
