6. Getting (a little) sunshine. Researchers at the University of Edinburgh confirmed previous studies that found that subjects exposed to UV light experienced a significant drop in blood pressure, apparently because the sun’s rays convert nitrate stored in your skin to nitric oxide, a compound that helps blood vessels retain their elasticity. Of course, you should never spend more than 10 minutes a day in the sun without sunscreen, because of the risk of skin cancer.
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.)
Talk to your doctor about adding supplements to your diet. Check with your doctor to see whether a natural remedy may help lower your blood pressure. Many natural remedies have scientific evidence to show that they can lower high blood pressure, but you should never attempt to replace your blood pressure medication without talking with your doctor.
Exercise. Doctors recommend at least 150 minutes per week of exercise to help reduce blood pressure. Brisk walking is excellent for reducing blood pressure and improving overall cardiovascular health, but other exercises can work too. Try jogging, riding a bike, swimming, dancing, or interval training to get your aerobic exercise. Strength training is also important to your heart health and can help reduce blood pressure.
Cardamom is a seasoning that comes from India and is often used in South Asian cuisine. A small study of 20 people investigating the health effects of cardamom found that participants with high blood pressure saw significant reductions in their blood pressure readings after taking 1.5 grams of cardamom powder twice a day for 12 weeks. You can include cardamom seeds or powder in spice rubs, soups and stews, and even baked goods for a special flavor and a possible positive health benefit.
“This does not mean I want them exercising so hard that they pass out, but I want them to be challenged, even if it means taking a break if they have to,” he said. “For some people, that may mean nothing more than a gentle walk with periodic breaks, but as the weeks go on they need to challenge themselves to get rid of those breaks, little by little.”
If you cannot be sure that your diet includes sufficient potassium, consider supplementation. However, including potassium in your diet gives better results, as an intake from food can be accessed by the body more efficiently. Potassium-rich foods include squash, sardines, salmon, raisins, potatoes, organs, pears, legumes, beets, bananas, carrots, and apricots, among many other fruits and vegetables.
A heart rate watch can let you quickly assess your pulse. Here's how to use one. Put the band that comes with it on your chest underneath your shirt. By looking at the watch during exercise, you can see your actual heart rate. This is a good alternative to taking your pulse manually. Ask your doctor to recommend the best target heart rate zone (or training zone) for you.
Monitor your blood pressure and talk with your doctor. A medical professional can check your blood pressure by using a sphygmomanometer and a stethoscope, or you can check it yourself using an automatic blood pressure monitoring device. If you have concerns about your blood pressure, talk to your doctor to determine what treatment options may work best for you. Blood pressure is usually divided into categories, which include:
