Pickering TG, et al. Recommendations for blood pressure measurement in humans and experimental animals: Part 1: blood pressure measurement in humans: a statement for professionals from the Subcommittee of Professional and Public Education of the American Heart Association Council on High Blood Pressure Research. Hypertension. 2005 Jan;45(1):142-61.
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.
Again, foods that lower blood pressure are usually high in potassium and similar nutrients. Famously rich in blood pressure-lowering potassium, one banana contains about 420 milligrams, or 11 percent of the 4,700 milligrams the American Heart Association recommends people consume daily. Surprisingly, however, many veggies are actually higher in potassium than these popular fruits. A cup of Swiss chard boasts 960 milligrams, a cup of cooked white beans has nearly 1,200 milligrams, and a whole avocado has 975 milligrams.
Taking a few moments to concentrate on breathing deeply can be a great help. Meditation and yoga are other great activities to reduce stress. We recommend Yoga Burn, by Zoe Bray Cotton for an amazing at-home yoga workout. In the long term, creating a routine that including one or more of these stress reduction techniques will be important to keep your blood pressure down in normal levels. 
The acronym FAST can help. F: Face drooping. Can the person smile? Is the smile uneven? A: Arm weakness. Is one arm weak or numb? If the person raises both arms, does one drift down? S: Speech difficulty. Is the person's speech slurred? Can they repeat simple sentences you give them? T: Time to call 911. If the person shows any of these symptoms, even if the symptoms go away, call 911. Check the time so you know when the symptoms began.
High blood pressure does not have any noticeable associated symptoms. This is, by far, the most worrisome problem that the healthcare industry and general population is facing when it comes to hypertension today. Chronic high blood pressure can cause damage to arteries and other areas of the body and, in turn, cause several complications to develop. This is why regular screenings for blood pressure levels are vital to help a person identify high blood pressure problems early on. This can help to administer treatment to stabilize blood pressure and avoid further damage to the body.
When added to a healthy diet, almonds can help influence lower blood pressure levels. In fact, almonds are included in the Dietary Approaches to Stop Hypertension — DASH — Diet. In the diet, almonds are included in the “nuts, seeds and legumes” group. The diet recommends eating four to five servings of this food group per week. With regard to almonds, one serving of almonds is just one-third cup. The healthy monounsaturated fat in almonds contributes to lower blood cholesterol levels and reduced arterial inflammation, which ultimately helps lower the pressure inside the arteries.
Swearing off cigarettes is probably the single best thing you can do for your heart. It’s good for your health in general, too. Not only does smoke hurt you over the long term, but your blood pressure goes up every time you have a cigarette. Lower your blood pressure and prolong your life by quitting. If you need help getting started, talk to your doctor.
Sunny days not only boost our mood, but they can help keep our blood pressure in check. A study published in the Journal of Investigative Dermatology found exposure to sunlight can alter the levels of nitric oxide in the skin and blood, therefore reducing the blood pressure. When exposed to sunlight, small amounts of nitric oxide are transported from the skin to the circulation lowering blood vessel tone. This decreases the risk of heart attack and stroke.
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?
