15 minutes of brisk walking every day? It really does help you live longer.

A brisk fifteen-minute walk a day can extend your life. A new study shows that brisk walking reduces the risk of death by as much as 20 percent.

We've known for a while that walking is healthy. But this study from Vanderbilt University in the US shows that the speed at which you walk is at least as important as the duration.

It turns out that 15 minutes of brisk walking every day has a greater impact on your life expectancy than hours of slow, slow plodding. Even people who already do light exercise can further improve their health by adding some brisk walking.

The benefits lie primarily in protecting against cardiovascular disease . Brisk walking increases the heart's efficiency, helps regulate blood pressure and cholesterol, and contributes to a healthy body weight.

According to the researchers, this makes it an accessible and affordable way to exercise, achievable for almost everyone. Even those without access to a gym or a healthy diet can benefit from a brisk daily walk.

The study specifically focused on participants with limited financial resources. According to the researchers, this group is often overlooked in scientific studies, despite the fact that this group often struggles with stress, unhealthy eating habits, smoking, and pollution.

“That is why it is all the more important to find simple ways for them to improve their health,” concludes research leader Wei Zheng.
