Are 10,000 Steps a Day Necessary, for Good Health?. Cumulatively, 10,000 steps equates to about five miles.
The health advice dates back to a mass-produced pedometer popularized in the wake of the 1964 Tokyo Olympics and invented by a Japanese clockmaker. Researchers today say that the 10,000 number is more arbitrary than based in actual science.
A study of women in the their 70s conducted by doctors with the Harvard T.H. Chan School of Public Health in 2019 found that the risk of premature death falls by 40 percent with 4,400 steps a day.
The risk of premature death continues to fall up to about 7,500 steps a day at which point the study found that it levels off. The findings of the Harvard study were backed by a 2020 study of middle-aged men and women. which found that 8,000 steps was the point at which added benefits began to taper off.
Even adding just two or three thousand steps to your daily routine makes a huge difference.
