A longer daily walk could be better for your heart than short strolls
The study looked at more than 33,000 adults aged 40 to 79 in the UK who walked fewer than 8,000 steps a day. The researchers, from the University of Sydney and the Universidad Europea in Spain, tracked their health over eight years.
People who walked in longer stretches had a lower risk of heart problems than those who walked in short bursts. Whether that's because they were fitter to begin with isn't fully clear from the study, but the researchers did try to control for this by taking into account factors such as whether the person smoked, was obese or had high blood pressure.
Even among the least active, those who walked under 5,000 steps a day, longer walks appeared to make a difference.
