One of the easiest ways to manage your blood pressure is simply making healthy life choices such as eating low-sodium diet, committing to a regular exercise routine, and avoiding (excessive) alcohol. Smoking is one of the worst things that you can do to your cardiovascular system, and it’s important that you take steps to quit as soon as possible to avoid hypertension, even if you don’t yet suffer from it yet.
Eating nutritious foods that are packed full of vitamins and antioxidants is a great way of lowering your blood pressure and keeping it down for good. Raw vegetables and fresh fruits are vital to a healthy diet and play a key part in controlling your blood pressure. Spinach, tomatoes and garlic are all good choices for keeping blood pressure down. 
Scientists have long debated the effects of caffeine on blood pressure. But an analysis of 34 studies seems to have delivered a verdict. On average, consuming 200 to 300 mg caffeine (the amount found in one or two cups of coffee) raises systolic blood pressure by 8 mmHg and diastolic blood pressure by 6 mmHg. And the effects can last for up to three hours. (For reference, 8 ounces of drip coffee contain 100-125 mg of caffeine; the same amount of tea, 50 mg; an equal quantity of cola, about 40 mg.)
1. Concentrate on foods that lower blood pressure. Sugary, processed foods contain salt, sugar, damaged fats, and food sensitivities like gluten that contribute to or exacerbate high blood pressure. Shifting to a whole, unprocessed foods diet can dramatically impact your blood pressure. Many whole, unprocessed foods are rich in potassium, a mineral that supports healthy blood pressure. Some research shows that too much sodium and low amounts of potassium – can contribute to high blood pressure. Research shows people with high blood pressure can benefit from increased potassium in foods including avocado, spinach, wild-caught salmon, and sweet potatoes.
Although medications can lower blood pressure, they may cause side effects such as leg cramps, dizziness, and insomnia. “The best habits to establish for reducing blood pressure are the same ones for a healthy life; follow an anti-inflammatory diet, do consistent low-level physical activity throughout the day, and the time plenty of time to reduce stress by learning how to smell the roses,” said Dr. Barry Sears, president of the Inflammation Research Foundation, to Medical Daily in an email. Lowering blood pressure can be attained without a prescription, not just by remaining alert on salty foods, but also with these five little-known everyday habits:
Visit the zoo: Viewing and being around animals can be very therapeutic, having a positive effect on blood pressure levels. A study in Japan found that when people visited a zoo, their systolic blood pressure dropped by six percent and their diastolic blood pressure dropped by eight percent. It is thought that observing animals simulated the parasympathetic nervous system, which reduces blood pressure to help counteract stress-induced adrenaline spikes.
If you’re eating more fruits and vegetables, you’re already taking a positive step toward reducing salt and enhancing potassium intake. Sodium can be found in abundance in processed foods – anything that comes in a package, can, or especially from a fast food restaurant. If you’re over 50, or at higher risk, aim for no more than 1,500 mg/day. Check your food labels for sodium content. If you see that a food has more than 400-500 mg in a serving, see if there’s a lower-sodium option.
As simple as it sounds, breathing is an effective technique to lower blood pressure. Slow breathing and meditative practices such as yoga can help decrease the stress hormones that elevate renin — a kidney enzyme that raises blood pressure. "Sit in a comfortable chair with armrests. Your body should be as relaxed as possible. Place one hand on a part of your chest or preferably your abdomen. Watch your hand rise and fall with each breath...feel the breath as it moves into your abdomen,” Dr. John M. Kennedy, a cardiologist in Los Angeles, Calif., and author of the book The Heart Health Bible told Medical Daily in an email. This should be repeated seven times and can become a daily habit by doing deep breathing 10 minutes in the morning.
i am currently 63 years old and was on a higher daily dose of zestoretic from about 1992-2010 for 140/90 BP and slowly reduced my need (lower mg) for zestoretic by paying more attention to my health (diet, weight, exercise, etc), eventually (about 2014) i got down to 10mg of lisinopril (no more hctz) about once per week or as needed since i was monitoring BP at home. in late 2016, a new doctor recommended that i stop taking 10mg lisinopril, and my blood pressure was usually low about 100/60 after breakfast or exercise and would go up to about 130/90 in the evening. in 2017, my BP was 150/90 the morning before hernia surgery. anyway, long story short my BP seems to fluctuate a lot during the day, low (100/60) after exercise, low after breakfast, high (130/90) before going to bed. the low BP periods get shorter and shorter so i went back to taking 10mg lisinopril as needed, about once every 2 or 3 weeks and the low BP periods get long again. also my pulse seems to get higher (80) when my BP gets lower 100/60 and my pulse gets lower (70) when my BP gets higher (130/90). anyway, i recently moved so probably need to see another new doctor, but thought i would just let you know what is going on.
Blood pressure is written as two numbers, such as 112/78 mm Hg. The top, systolic, number is the pressure when the heart beats. The bottom, diastolic, number is the pressure when the heart rests between beats. Normal blood pressure is below 120/80 mm Hg. If you’re an adult and your systolic pressure is 120 to 139, or your diastolic pressure is 80 to 89 (or both), you have pre-hypertension. High blood pressure is a pressure of 140 systolic or higher and/or 90 diastolic or higher that stays high over time.
