“Exercise, particularly cardio and aerobic exercise, has been known to be a potent dropper of blood pressure for a long time, and we know that fruits and vegetables rich in potassium and naturally occurring nitrates can actually lower blood pressure as effectively as many of the medications,” he said. “So that, to me, is no surprise. It’s nice that they put it all together in this study.”
As explained by Dr. Rosedale, insulin stores magnesium. If your insulin receptors are blunted and your cells grow resistant to insulin, you can't store magnesium so it passes out of your body through urination. Magnesium stored in your cells relaxes muscles. If your magnesium level is too low, your blood vessels will constrict rather than relax, which will raise your blood pressure and decrease your energy level. Insulin also affects your blood pressure by causing your body to retain sodium. Sodium retention causes fluid retention. Fluid retention in turn causes high blood pressure and can ultimately lead to congestive heart failure. If your hypertension is the direct result of an out-of-control blood sugar level, then normalizing your blood sugar levels will also lower your blood pressure readings into the healthy range.
Groundbreaking research published in 1998 in the journal Diabetes reported that nearly two-thirds of the test subjects who were insulin resistant (IR) also had high blood pressure, and insulin resistance is directly attributable to a high sugar, high grain diet, especially if accompanied by inadequate exercise. So, chances are that if you have hypertension, you also have poorly controlled blood sugar levels, because these two problems often go hand in hand.
Chocolate lovers can rejoice because consuming dark chocolate daily may lower high blood pressure. The flavanols in dark chocolate appear to activate nitric acid, which is a gas that allows the blood vessels to relax and widen, reports the Science Daily website. In a study published in the March 2010 issue of the "European Heart Journal," Dr. Brian Buijsse and colleagues from the German Institute of Human Nutrition in Germany found that participants who ate approximately 7.5g of dark chocolate a day had lower blood pressure and had a 39 percent less likely chance of having a heart attack or stroke.
Omega-3 fats are typically found in flaxseed oil, walnut oil and fish, with fish being by far the best source. Unfortunately, most fresh fish today contains dangerously high levels of mercury. Your best bet is to find a safe source of fish, or if this proves too difficult, supplement with a high quality krill oil, which has been found to be 48 times more potent than fish oil.
But weightlifting can also have long-term benefits to blood pressure that outweigh the risk of a temporary spike for most people. And it can improve other aspects of cardiovascular health that can help to reduce overall cardiovascular risk. The Department of Health and Human Services recommends incorporating strength training exercises of all the major muscle groups into a fitness routine at least two times a week.
7. Visit your chiropractor. A special chiropractic adjustment could significantly lower high blood pressure, a placebo-controlled study suggests. “This procedure has the effect of not one, but two blood–pressure medications given in combination,” study leader George Bakris, MD, told WebMD. Your chiropractor can create an effective protocol that helps normalize blood pressure without medication or other invasive procedures.
In most cases where high blood pressure is diagnosed, the cause remains unclear. One review paper in the International Journal of Hypertension explains that this accounts for around 90% of all hypertension diagnosis and is usually referred to as essential hypertension. Secondary hypertension is diagnosed when a cause can be identified. Potential causes of secondary hypertension may include:
Sleep. Short and poor-quality sleep are both associated with raised blood pressure (40). On the other side of the spectrum, excessively long sleep may also be harmful. One study found increased blood pressure in those who got fewer than five hours of sleep per night and in those who averaged more than nine hours of sleep per night, when compared with people who slept around seven hours (41). I suspect that it’s not the long sleep itself that is the problem, but that some underlying condition is both increasing sleep requirement and raising blood pressure.
