A landmark systematic review and meta-analysis challenges the long-held belief that 10,000 steps are necessary for optimal health. The new data, synthesizing findings from 35 cohorts, reveals that achieving just 7,000 steps per day is associated with a dramatic 47% reduction in all-cause mortality compared to a baseline of 2,000 steps . This establishes a more accessible, yet highly impactful, daily target for health optimization and longevity.
