08 Apr Should 15,000 Steps a Day Be Our New Exercise Target?
By Gretchen Reynolds
Taking 10,000 steps per day is often suggested as a desirable exercise goal for people who wish to improve their health. But a new study of postal workers in Scotland suggests that that number could be too conservative and that, to best protect our hearts, many of us might want to start moving quite a bit more.
It has been almost 70 years since the publication of the London Transit Workers Study, a famous work in which researchers tracked the heart health of London bus drivers and conductors. They found that the conductors, who walked up and down bus aisles throughout the workday, were substantially less likely to develop or die from heart disease than the drivers, who sat almost constantly while at work.
This study was one of the first to persuasively show that being physically active could lower someone’s risk for heart disease, while being sedentary had the opposite effect.
Since then, countless large-scale studies have substantiated that finding, and at this point, there is little doubt that moving or not moving during the day will affect the health of your heart.
