In this study, taking a nap during the day was associated with an average 5 mmHg drop in systolic blood pressure. “These findings are important because a drop in blood pressure as small as 2 mmHg can reduce the risk of cardiovascular events such as heart attack by up to 10 percent,” Kallistratos said.

Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body. When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need.

When we stand up from sitting or lying down, our blood vessels respond to gravity by narrowing to prevent our blood pressure falling. This ensures a steady supply of oxygenated blood to the brain. Orthostatic hypotension is a form of low blood pressure.

Low blood pressure is a measurement of 90/60mmHg or lower. When your blood pressure drops, your heart rate increases and the blood vessels in other parts of the body constrict (narrow) to help maintain blood pressure.

When your blood pressure drops, your heart rate increases and the blood vessels in other parts of the body constrict (narrow) to help maintain blood pressure. If your heart rate does not increase enough, or if your blood vessels do not constrict enough to maintain blood pressure, your blood pressure will fall.
