High blood pressure: jumping out of bed in the morning may cause dizziness

Doctors report that people with high blood pressure who rise abruptly can experience dizziness from a temporary drop in venous return, and clinicians note a natural morning blood pressure surge that can increase cardiovascular stress.

Doctors and cardiologists are highlighting a common morning habit to avoid for people with high blood pressure. High blood pressure is pressure in the arteries that deliver blood from the heart to the body. Normal adult blood pressure is generally reported as about 120/80, with higher ranges classified as hypertension. Clinicians report that rising too quickly from bed can cause dizziness or fainting, particularly for people taking antihypertensive medications. Key facts: - The Centers for Disease Control and Prevention is reported as saying nearly half of U.S. adults have high blood pressure. - Normal and hypertension ranges are reported roughly as 120/80 for normal, Stage 1 as 130–139/80–89, and Stage 2 as above 140/90. - Menhel Kinno, MD, and other clinicians say rising abruptly can cause a temporary drop in venous return, which may lead to dizziness, lightheadedness or fainting. - Doctors report a natural morning blood pressure surge driven by circadian rhythms, increased sympathetic activity and hormonal shifts, and that surge can amplify cardiovascular stress. - Reported measures mentioned by clinicians include sitting briefly on the edge of the bed, hydrating, taking prescribed medications, and delaying vigorous exercise for 30 to 60 minutes after waking. Summary: Clinicians report that the morning blood pressure surge can amplify cardiovascular stress, particularly for people with uncontrolled hypertension or a history of heart disease. Reported guidance from the clinicians quoted includes brief sitting on awakening, hydration and delaying vigorous activity, and they note that exercise timing and intensity can be personalized with a treating physician.
