How much water should I drink for orthostatic hypotension?
Drinking 500 mL of water improved orthostatic tolerance by 5±1 minute (range, −1 to +11 minutes, P<0.001). After drinking 500 mL of water, supine mean blood pressure increased slightly (P<0.01) as the result of increased peripheral resistance (P<0.01).

If you’re dehydrated, even slightly, your heart has to work harder to pump blood, which can increase your heart rate and cause an irregular heartbeat or palpitations. Dehydration thickens your blood and makes blood vessel walls constrict which can cause hypertension, or high blood pressure, and strain your heart.
