Due to gravity pulling blood towards the legs and abdomen, the heart uses more force to pump blood to the head

than them. On the other hand, in a supine posture since the head, abdomen, and legs are effected by the same

gravity, it takes less force for the heart to pump blood to the head.

If the position of the wrist is higher than that of the heart on measurement, the blood pressure result of the wrist

can be measured lower than the same level of the wrist cuff as the heart.

If you lean forward or sit on a desk, sofa and low table, pressure will be given to your abdomen. So then your blood

pressure can increase because the wrist cuff position is lower than your heart.

There is a distinct blood pressure difference between lying down, sitting and standing.

The blood pressure of the standing posture is about 5 mmHg higher than that of the lying down posture on diastole

while the blood pressure of the lying down posture is 8 mmHg higher than that of the sitting posture.

The blood pressure of legs-crossed is about 28 mmHg higher than that of the legs-spread posture.

When you sit at a table without armrests and measure it, diastolic blood pressure is about 6 mmHg higher.

According to statistics from several studies, there is a significant decrease in blood pressure in sitting posture

(upright) and standing (standing) posture rather than in both upper and lower (lying) postures. This posture also

affects blood pressure, but illness, stress and weight can also affect blood pressure. Undoubtedly, there is a

difference in blood pressure by posture according to age. Young adults in 20s and 30s have little or no difference in

blood pressure depending on their posture.
