A major 2023 analysis from Harvard T.H. Chan School of Public Health examined more than 116,000 adults over 30 years to identify the exercise levels most strongly linked to longer life. Published in Circulation, the study found that people who performed 2–4 times the recommended weekly activity levels had significantly

A major analysis published in The Lancet Public Health examined device‑measured step counts across large adult cohorts to understand how daily movement influences mortality and chronic disease risk. The study found a strong, consistent dose‑response relationship: as step count increases, the risk of early death and major health conditions declines

A 2022 study published in Nature Medicine found that just 3–4 minutes of vigorous incidental activity per day — such as climbing stairs quickly, power‑walking uphill, or running for the bus — is associated with a 40% reduction in all‑cause mortality compared with doing none. This research reframes longevity by
