Energy balance

Reallocating time from sedentary behavior to moderate-to-vigorous physical activity (MVPA) significantly reduces all-cause mortality risk, with the magnitude of benefit increasing as the intensity of the substituted activity increases.

To lower your risk of death, prioritize replacing sitting time with moderate-to-vigorous activity (like brisk walking, jogging, or cycling) over light activity. The more intense the activity you swap in, the greater the mortality benefit. You do not need to find extra time; simply displace sedentary time with this higher-intensity movement.

GoodSupportsHIGH confidence
It seems that reallocations of sedentary time to LPA or MVPA are associated with significant reduction in mortality risk. Current evidence appears to consistently suggest that reductions in mortality risk are greater when time spent sedentary is replaced with higher intensities of physical activity.
