In a hot tub, as the water comes through the pipes, it has a degree of force. This force is caused by the action of the pump, which puts energy into the circulating system and forces the water through the pipes. When the pump is off, there still may be water in the pipes, but there is no force. The degree of force in the system when the pump is on can be gauged in several ways, such as by putting your hand in front of a “jet.” Another way would be to have a device to measure the amount of force that the water exerts against the walls of the pipes as it circulates. Such a device might yield a numerical measurement of the force, or pressure, of the water within the pipes.
When you get a high blood pressure reading at the doctor's office, it might be tough for you to understand exactly what impact those numbers can make on your overall health, since high blood pressure has no unusual day-to-day symptoms. But the truth is, having high blood pressure is a serious health risk—it boosts the risks of leading killers such as heart attack and stroke, as well as aneurysms, cognitive decline, and kidney failure. What's more, high blood pressure is a primary or contributing cause of death in more than 1,000 deaths a day in the United States.
While most Americans with hypertension are treated primarily with drugs, “these drugs do not come close to eliminating all the cardiovascular ills associated with the typical American diet and sedentary lifestyle,” observes Danine Fruge, MD, Medical Director at the Pritikin Longevity Center in Miami. Over the last four decades, the Center has helped thousands worldwide lower blood pressure naturally and significantly reduce many cardiovascular risks.
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.
Don’t assume that your doctor is aware of these facts. If you are diagnosed with mild, high blood pressure, you likely will be prescribed medication, instructed that it is helpful, and told that you must take it for the rest of your life. But before accepting this potentially dangerous treatment, it may be to your advantage to seek answers to the following questions: “What caused my high blood pressure?” and “Can I remove those causes and reverse this condition?” 

Do something that's moderate in intensity -- like brisk walking -- for at least 30 minutes a day, 5 or more days a week. That may be enough to keep you off medications or help them work better. Exercise can lower your blood pressure by as much as five to 15 points. Gradually make your workouts more intense to keep lowering your blood pressure to safer levels.
Monitor your blood pressure and talk with your doctor. A medical professional can check your blood pressure by using a sphygmomanometer and a stethoscope, or you can check it yourself using an automatic blood pressure monitoring device. If you have concerns about your blood pressure, talk to your doctor to determine what treatment options may work best for you. Blood pressure is usually divided into categories, which include:[22]
