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 DASH (Dietary Approaches to Stop Hypertension) diet has been proven best for controlling blood pressure, according to the American Heart Association. People who follow the diet eat 2,000 calories a day of fruits, vegetables, low-fat dairy foods and whole grains. The diet is rich in potassium, magnesium and calcium, as well as protein and fiber, and low in sodium. Foods on the diet are low in saturated fat, total fat, and cholesterol.
Get moving at least a little bit every day, with a standard recommendation of 30-60 minutes a day, 3-5 times a week. Get your heart pumping at a moderate intensity for a few times a week, and mix it up with some strength training. Because life happens, on the days when you can’t fit it in, try to build more activity into your day by parking further away, taking the stairs instead of the elevator, or even just doing a quick sprint or two up and down the block. Every little bit helps.
Eat potassium- and magnesium-rich foods. Potassium can help regulate your heart rate and can reduce the effect that sodium has on your blood pressure. Foods like bananas, melons, oranges, apricots, avocados, dairy, leafy green vegetables, tomatoes, potatoes, sweet potatoes, tuna, salmon, beans, nuts, and seeds have lots of potassium. Magnesium is thought to help blood vessels relax, making it easier for blood to pass through. Foods rich in magnesium include vegetables, dairy, chicken, legumes, and whole grains. It’s better to get vitamins and minerals from food, and a heart-healthy diet like the one we described above is a good way to ensure you get plenty of nutrients. However, you may want to talk to your doctor about whether taking certain supplements might help your blood pressure.
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:
Unlike the smooth action of the hot tub pump, the human heart expands and contracts mightily each second or so, causing your blood pressure to be comparatively high one moment, and comparatively low in the next. That is why we need two measurements when checking your blood pressure: one at the moment when the pressure is highest (your systolic blood pressure), and one a moment later, when the pressure is lowest (your diastolic blood pressure).
Other exercise options that don’t require a gym membership include body weight exercises, like pushups, squats, and jumping jacks. These exercises can be done at home or outside. For people who like going to the gym or running, these can be good ways to build community, notes Parker. Apps like Fitbit and MapMyRun can be helpful if you like keeping track of your steps, calories burned, weight, or number of miles run.
A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.
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).
