Previous studies have established that regular exercises help maintain blood pressure. However, recent studies have found that aerobic exercises such as brisk walking, jogging, swimming, cycling, dancing are quite effective in lowering blood pressure.
Researchers reviewed 54 clinical trials that measured the effect of aerobic exercises on the blood pressure readings. Overall result indicated that regular aerobic exercises decreased systolic blood pressure (upper reading) by 4 mm of Hg and diastolic blood pressure (lower reading) by 3 mm of Hg. Another interesting finding in the study was that doing aerobics regularly not only decreased blood pressure in those suffering from high blood pressure but also in those with normal blood pressure. Hence aerobic exercises can prevent high blood pressure from occurring in the first place apart from lowering it in hypertension patients.
Experts therefore recommend doing some form of aerobic exercise for at least 25-30 minutes 3-4 times in a week. If you are planning to start an aerobic routine for the first time, or after a long gap, do consult your doctor first. Also do not stop taking anti-hypertensive medications unless the doctor says so.
