Steps matter: 9,000–10,000 daily steps linked to big drops in death and heart disease
A UK Biobank study of 72,174 adults wearing accelerometers found that increasing daily steps up to about 9,000–10,000 is linked to a 39% lower risk of death and a 21% lower risk of cardiovascular disease, with benefits already appearing around 4,000–4,500 steps and regardless of sedentary time; the study is observational and cannot prove causation, and high sedentary time still carries risks.
