Achieving 8.75 marginal MET-hours per week of non-occupational physical activity (equivalent to 150 minutes/week of moderate-to-vigorous aerobic activity) significantly reduces the risk of all-cause mortality, cardiovascular disease, and total cancer incidence compared to inactivity.
To significantly lower your risk of early death and heart disease, aim for 150 minutes per week of moderate-to-vigorous activity (like brisk walking) outside of work. This is the most impactful change you can make if you are currently inactive. Benefits are largest when moving from zero activity to this level.
Compared with inactive individuals, adults accumulating 8.75 mMET- hours/week had 31% (95% CI 27 to 35) and 29% (95% CI 23 to 34) lower risk of all- cause and CVD mortality, respectively, whereas the risk difference for total cancer mortality was 15% (95% CI 11 to 19).
