High blood pressure, also known as hypertension (See blood pressure chart below) is called the “silent killer” for a reason — there are no obvious symptoms but it can result in heart attack, stroke and even death. The good news is there’s a lot you can do to maintain healthy blood pressure or get back to one, often without the need for medications.

Keep in mind that sea salt and kosher salt contain the same amount of sodium as table salt.[6] 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.[7]
Sunny days not only boost our mood, but they can help keep our blood pressure in check. A study published in the Journal of Investigative Dermatology found exposure to sunlight can alter the levels of nitric oxide in the skin and blood, therefore reducing the blood pressure. When exposed to sunlight, small amounts of nitric oxide are transported from the skin to the circulation lowering blood vessel tone. This decreases the risk of heart attack and stroke.

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?”
Also, be sure that the quality chocolate has large quantities (a minimum of 70%) of cocoa - the active ingredient that lowers the blood pressure. Cocoa has antioxidant-rich compounds called flavanoids, which help dilate blood vessels and assist in glucose metabolism. Surprisingly, dark chocolate contains more of these antioxidant compounds than even the famed blueberry.
Now I work with patients with high blood pressure every single day in my clinic. I’m board-certified chiropractic physician and people come into my office all the time with high blood pressure. And over the years I learned that traditional lifestyle changes do not have the answers for these patients. On top of that many hate the idea of taking drugs to manage their high blood pressure. 
If you happen to love any of the above alternative approaches, or are doing it as part of your healthy lifestyle, you can continue to do so. Remember they complement, and not necessarily replace traditional approaches and medications that your doctor suggests. You might see only a modest reduction in your blood pressure, but you know what...it is probably not going to hurt either!
National guidelines recommend not getting more than 2,300 milligrams of sodium a day (about 1 teaspoon of table salt). The limit is 1,500 milligrams a day for some people, depending on age and other things. By staying on a sodium-restricted diet, your systolic blood pressure (top number) may drop two to eight points. Salt-restricted diets can also help enhance the effects of most blood pressure medications.
Caffeine can raise blood pressure by tightening blood vessels and magnifying the effects of stress, says James Lane, PhD, a Duke University researcher who studies caffeine and cardiovascular health. "When you're under stress, your heart starts pumping a lot more blood, boosting blood pressure," he says. "And caffeine exaggerates that effect." (Not sure whether you need to cut back? Here are 6 physical symptoms that mean you're drinking too much coffee.) 

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]
