A landmark study published in The Lancet found that just 15 minutes of moderate exercise per day — roughly 90 minutes per week — is associated with three additional years of life expectancy and a 14% reduction in all‑cause mortality. This research remains one of the most influential pieces of evidence showing that even small amounts of movement deliver meaningful longevity benefits.
Key Insights
- Based on data from 416,000+ adults
- Benefits observed even in people who didn’t meet the 150‑minute guideline
- Each additional 15 minutes per day reduced mortality risk by a further 4%
- Strong evidence that some movement is dramatically better than none
Why It Matters for Longevity at Work
This study reframes physical activity as a minimum effective dose conversation. For busy workers, it reinforces that short, achievable bouts of movement can meaningfully improve long‑term health and productivity.
