Many scientific studies have shown that in general, physical activity can reduce blood pressure. In confirmation of these findings, a study published in a recent issue of the Annals of Internal Medicine indicates that aerobic exercise (exercise in which oxygen is used as a primary fuel source) in particular is effective for reducing blood pressure.

Researchers from Tulane University in New Orleans analyzed over 2,400 people who participated in 54 studies that examined the effect of aerobic exercise on blood pressure.

Overall, participation in aerobic exercise reduced blood pressure in people with high blood pressure as well as people who did not have high blood pressure. In addition aerobic exercise also reduced blood pressure in both overweight and normal-weight study participants.

If you've been told by your health care provider that you have borderline high or high blood pressure, adding aerobic activity to your lifestyle (after receiving an okay from your physician) can reduce blood pressure. Walking, swimming, bike riding and hiking are affordable aerobic activities that could make a difference in your health if you participate in them regularly. The American College of Sports Medicine recommends that you exercise at a moderate intensity for at least 30 minutes most days of the week.
