Elevating your feet will not lower blood pressure and will actually increase the blood pressure reading when your feet are higher than your heart. On the other hand, if you are doing activities to relieve stress such as yoga (which often elevates your legs, such as legs-up-the-wall pose), then over the long run, these stress reducing activities may help to decrease your blood pressure (but it is not the act of elevating the legs that is lowering the blood pressure it is the stress relieving activity).
Low levels of vitamin D—which the body gets from fortified foods, supplements, or the skin’s exposure to sunlight—have been linked to high blood pressure. But most research has found that taking supplements doesn't seem to help. Dr. Bisognano says the jury’s still out on how the two are linked. “I have found that people with extremely low vitamin D levels can have high blood pressure that’s more difficult to treat,” he says, “but I can’t be sure whether that’s the driving issue.”
Exercise. Some patients will cringe at the suggestion of exercise, because they envision a chronic cardio scenario like a mouse on a running wheel. Spread the good news: exercise of all kinds—endurance, dynamic resistance, HIIT, isometric resistance—has the potential to reduce blood pressure (38). Whatever exercise your patients will actually do on a regular basis is the best recipe for success. In patients with extreme hypertension, be cautious with exercises that may further increase blood pressure to an unsafe zone (39).
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.
What is a normal blood pressure? Blood pressure is essential to life because it forces the blood around the body, delivering all the nutrients it needs. Here, we explain how to take your blood pressure, what the readings mean, and what counts as low, high, and normal. The article also offers some tips on how to maintain healthy blood pressure.

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.
