Orthostatic hypertension involving the systolic BP is known as systolic orthostatic hypertension. High diastolic blood pressure measured while standing in a person who stood up shortly after waking up. When it affects an individual's ability to remain upright, orthostatic hypertension is considered as a form of orthostatic intolerance.
Even small increases in the blood pressure may be sufficient to maintain blood flow to the brain on standing. [33] In dysautonomic patients who do not have a diagnosis of high blood pressure, drinking 2–3 liters of fluid a day and taking 10 g of salt can improve symptoms, by maximizing the amount of fluid in the bloodstream.

The basic physiological change that occurs in the body during prolonged standing or sudden stand from supine position is that there will be increased pooling of blood in the legs. This decreases the venous return, and so there will be decreased cardiac output, which ultimately causes systolic blood pressure to fall (hypotension).
Standing for more than two hours a day saw increased circulatory disease risks. Standing too much can raise the risk of circulatory disease, a new study says. Experts say the key is to 'just move.'
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
This condition is believed to be due to calcification of the arteries resulting in abnormally high blood pressure readings with a blood pressure cuff while intra arterial measurements of blood pressure are normal. [95] Orthostatic hypertension is when blood pressure increases upon standing. [96]
Power walk (10 minutes): Now that your body is moving and blood is flowing, increase your pace to your maximum walking pace, making sure you engage arms and core and ideally varying your incline.
Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor, so requires rapid and effective circulatory and neurologic compensations to maintain blood pressure, cerebral blood flow, and consciousness. When a human stands, about 750 ml of thoracic blood are abruptly translocated downward.
