why does blood pressure fluctuate
The devilâs in the details. Everyoneâs blood pressure fluctuates throughout the dayâthus evaluating it is like shooting at a moving target. Complex bodily systems (including the heart, arteries, nerves, hormones and kidneys) regulate and affect blood pressure. It can fluctuate from minute to minute, rising when youâre active, for instance, and typically dropping when you rest or sleep. Just standing up can cause pressure to riseâor fall.
Since the blood vessels are already in a constricted state, they become more sensitized to changes in the bodyâs condition. For someone with hypertension, factors such as stress, physical exertion or poor dietary habits can result in immediate fluctuations in blood pressure.
