Ginger may help control blood pressure. In animal studies it has been shown to improve blood circulation and relax the muscles surrounding blood vessels, lowering blood pressure. Human studies so far have been inconclusive. Commonly used in Asian foods, ginger is a versatile ingredient that can also be added to sweets or beverages. Chop, mince, or grate fresh ginger into stir-fries, soups, and noodle or vegetable dishes, or add it to desserts or tea for a refreshing taste.
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.)
Elevated blood pressure refers to an increase in the pressure or tension applied to blood vessels. Blood pressure is measured by providing two different readings, including systolic blood pressure and diastolic pressure. Blood pressure levels that raise beyond 120/80 is considered elevated. At 130/80, a person is considered to be experiencing high blood pressure. High blood pressure is often classified into two stages. State 1 hypertension is diagnosed when blood pressure levels fall between 130-139/80-89. Stage 2 hypertension is diagnosed when a patient’s blood pressure becomes higher than 140/90.
Arteries are naturally flexible and smooth, which allows blood to easily move throughout the body. High blood pressure creates extra force against the artery walls, which damages the lining of the arteries. As they become narrower and harder, this restricts blood flow, and when blood flow is lowered, the heart has to work harder to pump it through the body, which only makes the problem worse.
In a 2014 review of previous studies, people who consumed probiotics—healthy bacteria found in yogurt and other fermented foods—saw their systolic blood pressure reduced an average of 3.6 points, and their diastolic reduced 2.4 points, compared to those who didn’t. Those with blood pressure higher than 130/85 experienced the greatest reductions, along with those who took probiotic supplements or ate probiotic foods for longer than two months. (Any blood pressure over 120/80 mm Hg is considered elevated.) Experts say any effect probiotics have on blood pressure is likely modest, but that they may play a role in an overall heart-healthy lifestyle.
Celery seed is an herb used to flavor soups, stews, casseroles, and other savory dishes. Celery has long been used to treat hypertension in China, and studies in rodents have shown that it may be effective. You can use the seeds, or you can juice the whole plant. Celery may also be a diuretic, which may help explain its effect on blood pressure. Researchers believe that a variety of substances in celery may play a role in lowering blood pressure. However, human studies are needed.
It's time to heed your partner's complaints and get that snoring checked out. Loud, incessant snores are a symptom of obstructive sleep apnea (OSA), a disorder characterized by brief yet potentially life-threatening interruptions in breathing during sleep. And many sleep apnea sufferers also have high levels of aldosterone, a hormone that can boost blood pressure, according to University of Alabama researchers. In fact, it's estimated that sleep apnea affects half of people with high blood pressure.
