The Business of Medicine Discovery at HMS

Step Back

Is taking 10,000 steps daily  the key to better health and longevity? Maybe not, say HMS researchers at Brigham and Women’s Hospital. An observational study over four years of more than 16,000 women, average age of 72, found that those who walked least—2,700 steps on average daily—had the greatest mortality rate, while those who achieved 4,400 steps daily had a 41 percent decrease. Mortality rates continued to decrease with more steps taken, before leveling off at 7,500.
