Question

what is the difference between the blood in your brain when you stand on head and the pressure when you stand by feet​

Answer 1

Answer:

The medical definition of a head rush is a systolic blood pressure drop of at least 20 mm Hg (millimeters of mercury) or a diastolic blood pressure drop of at least 10 mm Hg within 2 to 5 minutes of standing. When you stand up quickly, gravity pulls your blood toward your legs and your blood pressure quickly drops.
