A large British study followed more than 33,000 adults with low physical activity who walked fewer than 8,000 steps a day.1][2][4] Participants wore an accelerometer on their wrist for 3 to 7 days to measure their steps and their distribution.2 A study published in the Annals of Internal Medicine found that people grouping steps into longer, uninterrupted walks had a lower risk of premature death and heart disease than those with shorter intervals.[1][2][3] Those who walked regularly for longer than 15 minutes had an 80% lower risk of death from any cause and a nearly 70% lower risk of cardiovascular disease compared to those with most steps in intervals of less than 5 minutes.2][3] Longer walks of at least 10-15 minutes provide greater cardiovascular benefits than the same number of steps in short bursts.[1][2][3] The findings show a dose response: the longer the walk, the better the health outcomes, especially in people who are not very active.[3][4] The longer the walk, the better the health outcomes, especially in people who are not very active.[4][5
