Breaking up prolonged sitting every 30-60 minutes with 2-5 minutes of movement. Prolonged sitting increases all-cause mortality risk independent of exercise habits.

Prolonged sedentary time is independently associated with increased cardiovascular disease mortality risk, with a hazard ratio of 1.179.
Physical activity is effective for improving sleep quality in women.
Studies with lower risk of confounding due to pre-existing diseases showed weaker associations between sedentary behavior and all-cause mortality (HR 1.18).
High levels of sedentary time (median 7.26 hours/day) are significantly associated with substantially increased risk of metabolic syndrome.
