Summary: Research from the ProPASS Consortium reveals that just five minutes of vigorous activity like stair climbing or uphill walking could help reduce blood pressure. The study, which tracked over 14,000 participants across five countries, suggests that replacing sedentary time with exercise could significantly impact cardiovascular health.

Small Changes, Big Impact
In the global battle against high blood pressure, which affects 1.28 billion adults worldwide, a new study offers hope through surprisingly manageable lifestyle changes. Research published in Circulation demonstrates that even brief periods of exercise could make a meaningful difference in blood pressure control.
“High blood pressure is one of the biggest health issues globally, but unlike some major causes of cardiovascular mortality there may be relatively accessible ways to tackle the problem in addition to medication,” explains Professor Emmanuel Stamatakis, Director of the ProPASS Consortium from the Charles Perkins Centre.
Tracking Real-World Movement
The research team analyzed data from 14,761 volunteers across five countries, using wearable accelerometer devices to measure activity and blood pressure throughout day and night. This approach provided unprecedented insight into how different types of movement affect blood pressure in real-world conditions.
Participants’ daily activities were categorized into six types: sleep, sedentary behavior (like sitting), slow walking, fast walking, standing, and more vigorous exercise such as running, cycling, or stair climbing. The findings revealed that replacing sedentary time with 20-27 minutes of exercise could potentially reduce cardiovascular disease risk by up to 28 percent at a population level.
Every Minute Counts
“The finding that doing as little as five extra minutes of exercise per day could be associated with measurably lower blood pressure readings emphasises how powerful short bouts of higher intensity movement could be for blood pressure management,” notes Professor Stamatakis.
First author Dr. Jo Blodgett emphasizes the practical implications: “What’s unique about our exercise variable is that it includes all exercise-like activities, from running for a bus or a short cycling errand, many of which can be integrated into daily routines.”
