    Exercise has been called the “drug-free way to lower blood pressure” if you have hypertension.  Lack of physical activity can increase your risk for a heart attack or stroke, and can also contribute to obesity.  A regular exercise habit helps to control weight, stress, and helps to improve your blood pressure profile.


    Understanding your blood pressure numbers

    According to the American College of Sports Medicine, three out of four people over age 60 have hypertension, and more than 75 million Americans have elevated blood pressure.  High blood pressure is also referred to as a silent disease, because most people do not experience symptoms until blood pressure readings are quite high, or persist for sustained periods of time.  Normal blood pressure is a reading below 120/80.  Pre-hypertension is al systolic (upper) number of 120 to 139 or a diastolic (lower) number of 80 to 89, or both in combination. High blood pressure is diagnosed with a reading of 140/90 or higher.

    Systolic blood pressure measures the pressure in the arteries when the heart beats (heart muscle contraction).


    Diastolic blood pressure  measures the pressure in the arteries between heartbeats, when the heart muscle is resting and then filling again with blood.


    How exercise lowers blood pressure


    To have normal blood pressure, you need to have a strong heart.  A strong heart pumps blood efficiently through your circulatory system with less effort.  The less intensely your heart has to work, the lower the force needed to push blood through your arteries, and the lower your blood pressure will be.


    Intentionally being more physically active will help to lower your systolic blood pressure – the top number in the blood pressure reading.  Exercise can also help you avoid  blood pressure medication as you age, as aging is a risk factor for hypertension. 


    Which exercises are best for improving high blood pressure?


    Aerobic exercise, which helps to raise your heart rate and over time, strengthen your heart, should be the core element of a workout program designed to optimize blood pressure and cardiac health. But you don’t need to run a marathon! Just 30 minutes of heart-pumping exercise a day seems to be the best formula for lowering blood pressure or maintaining a healthy blood pressure. Any physical activity that results in sustained periods of an elevated heart rate and faster, deeper breathing is considered “aerobic” activity, including:


    • Household chores like manually mowing the lawn, raking leaves, gardening, scrubbing the floor
    • Brisk walking, jogging, running, swimming, biking, dancing, rowing
    • Climbing stairs
    • Using a treadmill, elliptical, stationary bike, or other aerobic gym equipment
    • Aerobic classes like Zumba, kickboxing
    • Weight training that involves very short rests between sets of exercise repetitions can also keep heart rate elevated


    Best timing of exercise to lower blood pressure


    If you decide to begin exercising, check with your doctor first to be clear on safe practices, especially if you have prehypertension or hypertension. Your doctor may have to adjust the levels or timing of certain medications, . Typically, medications prescribed for heart problems and high blood pressure, such as beta-blockers or calcium-channel blockers, lower or slow heart rate, so you need to understand what heart rate goals to set for your personal exercise regimen.

    You also should consider wearing some kind of heart rate monitor or tracker, especially if your doctor would like you to target a specific heart rate.  The tracker will show  if you are exercising too vigorously, which you may need to avoid if you have a history of a heart attack or other cardiac problems..  Cardiac rehabilitation can provide a safe environment where you can receive appropriate exercise instruction.


    Morning workouts or short workouts during daytime hours are best, because exercising close to bedtime can interfere with sleep, and poor sleep is actually a risk factor for hypertension.  Morning workouts also seem to provide sustained blood pressure benefits throughout the day.  If evening  is the only time you can work out, however, that’s  better than no workout at all.  Consistent timing works best for people taking blood pressure medications.


    Research seems to suggest that blood pressure control and response is better if you spread your workout minutes through the day.  Even standing up periodically can help to improve blood pressure.  A small study conducted at Arizona State University of 11 healthy people with prehypertension, published in the December 2012 issue of Medicine and Science in Sports and Exercise showed that three 10-minute walks during the day were more helpful in preventing blood pressure spikes than one 30-minute exercise effort, and had longer-lasting results. The study also showed that the intensity of these workouts was less important than sustaining an elevated heart rate for throughout each 10-minute interval.  Adding more short bursts of exercise throughout the day does seem to provide more blood pressure control.


    It’s important to understand that when you perform aerobic exercise, your body requires more oxygen, so your blood pressure, specifically the systolic pressure (upper number) will increase during exercise.  One indicator that you may be at risk of developing hypertension is if your blood pressure remains elevated for a period of time after you finish an aerobic workout.  Having a home blood pressure reading machine is a good idea if you face this risk or have any stage of hypertension.


    See if you qualify for a cardiac rehabilitation program if you are diagnosed with hypertension. Experienced health professionals can guide your initial workouts and develop a workout program with heart-rate goals you can then meet on your own. . Even a single session with an experienced personal trainer can help you to understand what your exercise limitations and goals should be.
