Scientists have long debated the effects of caffeine on blood pressure. But an analysis of 34 studies seems to have delivered a verdict. On average, consuming 200 to 300 mg caffeine (the amount found in one or two cups of coffee) raises systolic blood pressure by 8 mmHg and diastolic blood pressure by 6 mmHg. And the effects can last for up to three hours. (For reference, 8 ounces of drip coffee contain 100-125 mg of caffeine; the same amount of tea, 50 mg; an equal quantity of cola, about 40 mg.)
According to guidelines from the American Heart Association (AHA) and the American College of Cardiology (ACC), a reading below 120/80 mm Hg is classified as normal blood pressure. Those with a blood pressure reading anywhere from 120/80 up to 129/80 are classified within a category called elevated blood pressure. Hypertension is defined as a reading of 130/80 or higher.
When discussing blood pressure issues, the healthcare professional may ask questions about past medical history, family history, and medication use, including prescriptions, over-the-counter medications, herbal remedies, and food additives. Other questions may include lifestyle habits, including activity levels, smoking, alcohol consumption, and illegal drug use.
Digital blood pressure readings have two numbers – systolic blood pressure and diastolic blood pressure. The top number is your systolic blood pressure (the highest pressure when your heart beats and pushes blood around your body), and the bottom number is your diastolic blood pressure (the lowest pressure between heart beats). A blood pressure reading is usually these two numbers over each other – like 120/80.
Practice relaxation or slow, deep breathing. Practice taking deep, slow breaths to help relax. There are some devices available that promote slow, deep breathing. According to the American Heart Association, device-guided breathing may be a reasonable nondrug option for lowering blood pressure, especially when anxiety accompanies high blood pressure or standard treatments aren't well-tolerated.
As you age, your body goes through many changes that can put you at risk for other conditions. If you’re over 50, having a higher than usual systolic pressure might increase your risk of developing heart disease. Systolic blood pressure tends to increase steadily over time due to stiff arteries, a build-up of plaque, and a higher rate of cardiac and vascular disease. This means older adults need to be even more vigilant about monitoring their blood pressure and practicing heart-healthy self-care.
Hypertension, or high blood pressure, refers to the pressure of blood against your artery walls. Over time, high blood pressure can cause blood vessel damage that leads to heart disease, kidney disease, stroke, and other problems. Hypertension is sometimes called the silent killer because it produces no symptoms and can go unnoticed — and untreated — for years.
Lowering high blood pressure is as easy as one, two, tea: Adults with mildly high blood pressure who sipped three cups of hibiscus tea daily lowered their systolic BP by seven points in six weeks, found Tufts University researchers. The phytochemicals in hibiscus are probably responsible for the large reduction in high blood pressure, the study authors say.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
Diuretics can lead to an increase in potassium loss, known as hypokalemia, which, in turn can affect muscular function -- including the muscles of the heart. There is also an increased risk for gout with diuretics -- as well as the possibility of weakness, thirst, dehydration, and increased urination. Changes in blood sugar levels are also possible. Skin reactions, some severe, are possible with thiazide diuretics (such as hydrochlorothiazide). Potassium-sparing diuretics, such as spironolactone (Aldactone) may cause breast enlargement in males.
A study published in the Journal of Bioscience, Biotechnology and Biochemistry looked at the effect that vinegar has on blood pressure if it is introduced to your diet. The results of the research showed that consumption of acetic acid (which is found in apple cider vinegar) caused a significant reduction in hypertension (high blood pressure). The research found that the acetic acid reduced blood pressure by lowering the renin activity. Renin is an enzyme which helps regulate blood pressure. I mix 1-2 tablespoons in a glass of warm water in the morning. I have found like I like Braggs ACV with the mother.
Caffeine can raise blood pressure by tightening blood vessels and magnifying the effects of stress, says James Lane, PhD, a Duke University researcher who studies caffeine and cardiovascular health. "When you're under stress, your heart starts pumping a lot more blood, boosting blood pressure," he says. "And caffeine exaggerates that effect." (Not sure whether you need to cut back? Here are 6 physical symptoms that mean you're drinking too much coffee.)
Slash your blood pressure and lower your risk of chronic disease by making apricots a staple in your diet today. Whether you’re tossing some on a salad, eating dried apricots as a snack, or adding some to your favorite smoothie, these vitamin C-rich, beta-carotene-loaded fruits are the key to healthier blood pressure. Even better is the 3.3 grams of dietary fiber you’ll get per cup of apricots — research published in the Archives of Internal Medicine suggests that a high-fiber diet can significantly lower your blood pressure, too.
Various organizations including the United States Department of Agriculture recommend that Americans consume less than 2,300 milligrams (mg) of sodium per day. But the ideal limit is really no more than 1,500 mg per day for most adults. Unfortunately, the average sodium intake of Americans is more than 3,400 mg per day, according to the Centers for Disease Control and Prevention (CDC). This is partly because sodium is so easy to consume — just 1 teaspoon of salt contains 2,300 mg of sodium.
Because of the need for emergency care, it is important to recognize the early signs of malignant hypertension. The first giveaway is blood pressure of 180/120. You might have bleeding in the eyes due to rupture of the small blood vessels. Other malignant hypertension symptoms can include chest pain, dizziness, a headache, numbness in your extremities, and confusion.
Partner with your doctor. Ask if there are any take steps you can take to lessen medication side effects. For example, to lessen the effects of low blood pressure, it may help to avoid standing for a long time in the sun. In some cases, side effects such as fatigue or diarrhea may subside with time. In other cases, your doctor may change the dosage or prescribe another high blood pressure medication. A combination of medications sometimes works better than one medication alone by not only improving high blood pressure control but also by reducing side effects.
Monitor your blood pressure at home. Home blood pressure monitoring can help you keep closer tabs on your blood pressure, show if medication is working, and even alert you and your doctor to potential complications. Home blood pressure monitoring isn't a substitute for visits to your doctor, and home blood pressure monitors may have some limitations. Even if you get normal readings, don't stop or change your medications or alter your diet without talking to your doctor first.
The reasons for this astonishing success are not yet entirely understood. Certainly, two of the major causes of high blood pressure are being addressed: excessive dietary salt is completely eliminated, and it is likely that some patients experience some reversal of the atherosclerosis process. However, Dr. Campbell has suggested that additional mechanisms may be partly responsible for fasting’s remarkable effects, such as the rapid reduction of a phenomenon known as “insulin resistance.”
Controlling your blood pressure is a lifelong task. Blood pressure is only one of a number of factors that increase your risk of heart attack, stroke, and death. High cholesterol and diabetes are other risk factors. Lifestyle changes—such as weight loss, a healthy diet, and physical activity—can affect all three risk factors, but many people will also need medications.
4. Find an exercise that works for you (and do it). Moving more can help reverse high blood pressure. One meta-analysis of 65 studies found regular exercise provides both an acute and longer-term reduction in blood pressure. Whether you’re an exercise novice or a conditioned athlete, these four strategies can help you create an effective workout plan to optimize health.
6. Cultivate stress management. You don’t need a meta-analysis of cohort studies to prove stress can raise blood pressure, but they exist. You can’t eliminate stress, but you can minimize its impact. Research shows yoga and meditation create effective strategies to manage stress and blood pressure. If those aren’t your thing, consider other stress-relieving tactics including deep breathing or practicing mindfulness.
Both numbers in a blood pressure reading are important. But after age 50, the systolic reading is even more significant. Isolated systolic hypertension is a condition in which the diastolic pressure is normal (less than 80 mm Hg) but systolic pressure is high (greater than or equal to 130 mm Hg). This is a common type of high blood pressure among people older than 65.
How can I stabilize my blood pressure? A wide range of factors influences blood pressure, including anxiety, stress, and medications. High blood pressure can have severe complications, such as a heart attack or stroke. A person can address fluctuating blood pressure with home remedies and lifestyle changes.

While a rising heart rate will increase blood flow through the body, it does not necessarily correspond with an increase in the pressure of that blood flow. This is because blood vessels can increase in size (dilate) to facilitate larger quantities of blood. Even if your heart rate were to double, your normal blood pressure & high pulse may only slightly increase blood pressure.
