7,000 Steps: The Real Health Target
A new Lancet Public Health review of over 160,000 adults finds most health gains come from about 7,000 daily steps, with benefits beginning well before that and plateauing thereafter (except dementia, which may improve with more walking). The infamous 10,000-step target traces back to a 1960s Japan marketing campaign for the Manpo-kei, not science. Increasing activity from very low levels to around 7,000 steps substantially lowers risks of heart disease, dementia, cancer, diabetes, depression, falls, and premature death, with further gains from higher intensity and reduced sedentary time. Wearable trackers can help motivate consistent activity, but guidelines still emphasize sustainable habits, including sleep and, where possible, strength training.
