Changes in blood pressure when body is sitting supine standing?

Sitting:

- Blood pressure is typically lower when sitting than when standing. This is because gravity pulls blood down to the legs when you stand, which can increase pressure on the blood vessels in your legs and feet.

- Normal blood pressure for an adult sitting is less than 120/80 mm Hg.

Supine:

- Blood pressure is lowest when you are lying down (supine). This is because gravity is not pulling blood down to your legs, so there is less pressure on your blood vessels.

- Normal blood pressure for an adult lying down is less than 110/70.

Standing:

- Blood pressure is highest when standing up suddenly from a sitting or lying position. This is because your heart has to work harder to pump blood against gravity.

- Normal blood pressure for an adult standing is less than 130/80.

It is important to note that blood pressure can vary throughout the day and from person to person. If you are concerned about your blood pressure, talk to your doctor.
