New research indicates that the duration of daily walks significantly impacts heart health, with a single 15-minute continuous walk linked to a substantially lower risk of cardiovascular disease compared to multiple short bursts of activity. The study, published in October 2025 in the Annals of Internal Medicine, analyzed data from over 33,500 adults aged 40 to 79 who took fewer than 8,000 steps daily.
Lower Risk with Longer Walks
The researchers found a clear association between walk duration and heart health. Participants who primarily took walks of less than five minutes had an estimated 13% risk of heart and vascular disease over a 9.5-year period. In contrast, for those who gathered most of their steps during walks of at least 15 minutes, the risk was approximately 4%. For walks lasting 10 to 15 minutes, the risk was around 8%. This association was also observed in people who took fewer than 5,000 steps per day.
The Value of a Continuous Walk
The findings suggest that incorporating a 10 to 15-minute continuous walk into one’s routine can be beneficial for individuals who are not very active. This does not require a strenuous hike; a walk around the neighborhood after lunch, a stroll before it gets dark, or a journey to a slightly more distant shop can all suffice. The key is to maintain longer periods of continuous movement where possible, rather than exclusively taking short spurts.
Building a Walking Habit
Especially in autumn and winter, establishing a regular time for a walk can be helpful, such as a 15-minute loop after lunch when it is still light. The study emphasizes that one does not need to become an avid walker to see a benefit. The research shows a correlation, but it does not prove that the longer walks themselves are the direct cause; people who are able to walk for longer periods may be healthier in other ways as well.
Why a 15-Minute Continuous Walk is Worthwhile
The outcome is particularly interesting for people who are not very active, according to the researchers. You do not need to immediately add thousands of extra steps to adjust your walking habits. It can be a good start to walk for 10 to 15 minutes more often, instead of exclusively taking short bursts. This does not have to be a long forest walk. A loop through the neighborhood after lunch, a short walk before it gets dark, or a walk to a shop that is a little further away are all ways to stay in motion for a bit longer. Those short bursts in between continue to count, of course. The point is not to replace them with less activity, but to also build in a longer walking moment where possible.
How to Make a 15-Minute Walk a Habit
In the autumn and winter, it helps to choose a fixed time. For example, make a loop of a quarter of an hour after lunch, when it is still light outside. Feel free to start with five or ten minutes if a quarter of an hour is still too much, and build it up slowly. Walk at a comfortable pace and choose a route that you can easily maintain. For those who walk a bit more vigorously, this can also contribute to the Dutch exercise guidelines of at least 150 minutes of moderately intensive exercise per week, spread over different days.
