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.)
First, keep in mind that drugs have limited success. Most studies on diuretics and other blood pressure-lowering drugs suggest they lower the risk of cardiovascular events among those with blood pressure between 140/90 and 159/99 by 15 to 20%.3 The problem is, with this range of blood pressure, the risk of cardiovascular-related deaths has increased by 300 to 400% compared to people with normal blood pressure.
You can lower your systolic blood pressure (the top number) by switching to the DASH diet. The DASH diet is based on 2,000 calories a day. It's rich in fruits, vegetables, and low-fat dairy products. It's also low in saturated fat, cholesterol, and total fat. According to studies, adopting a DASH diet can reduce systolic blood pressure by eight to 14 points. The goal is to keep you blood pressure goal is less than 120/80.
Conventional allopathic medicines and lifestyle modifications still remain the backbone of hypertension management. What about alternative treatments, though? Well,in 2013, the American Heart Association came out with an official statement addressing this issue, published in the journal Hypertension. The statement runs about 59 pages, but I will try to summarize this statement's conclusion's addressing the efficacy of approaches like acupuncture, yoga, meditation, etc in treating high blood pressure. Please note that these conclusions apply only to treatment of high blood pressure, and not to other health/psychological benefits that may be derived from doing these activities.
Coconut water finds itself high on the list of home remedies for high blood pressure. One of the causes for high blood pressure is an imbalance of electrolytes in the blood. Because coconut water contains an adequate supply of minerals and salts, it can help counter this imbalance. Modern researchers say the potassium content in coconut water plays a huge role in lowering blood pressure. Both potassium chloride (seen in supplements) and potassium citrate (seen in foods) can help lower blood pressure. Potassium helps balance out the level of sodium in your blood and keeps your body functioning properly.
If you are in this 130/80 range, reducing your blood pressure can help protect you from heart attack, stroke, kidney disease, eye disease, and even cognitive decline. The goal of the new guidelines is to encourage you to treat your high blood pressure seriously and to take action to bring it down, primarily using lifestyle interventions. "It is well documented that lifestyle changes can lower blood pressure as much as pills can, and sometimes even more," says Dr. Fisher.
Keep in mind that sea salt and kosher salt contain the same amount of sodium as table salt. Salt substitutes contain potassium chloride, which is not safe for some people, so you may want to avoid it. Instead, look into sodium-free alternatives to replace salt in your diet, such as lemon juice, flavored vinegar, fresh herbs, and salt-free herb and spice blends.
