This is another reason to look at ways to work a couple of walks or any form of exercise into your day. This study found that one 30-minute afternoon walk improved blood pressure readings for 24 hours among adults with borderline hypertension, BUT, Three 10-minute walks spaced throughout the day improved overall blood pressure just as effectively, but unlike the single session, they also blunted subsequent spikes in pressure, which can indicate worsening blood pressure control. So, the 7 min workout, the four minute workout, the 10 min walk to the furthest bathroom from your desk, the quick spin around the block with your dog, it does not take much to make a big difference in your health. Even moderately elevated blood pressure over time is stressful on your heart, kidneys, blood vessels. So, what is keeping you from the 10 minute walk?
