A 12-year study of over 41,000 Chinese adults found that sitting fewer than two hours a day was linked to higher death and cardiovascular risk than moderate sitting, especially among manual laborers.
Turns out “sit less” isn’t a one-size-fits-all rule. A 12-year study tracking over 41,000 adults in China found the sweet spot for avoiding death or cardiovascular trouble was around four hours of sitting a day, StudyFinds reports.
People sitting less than two hours actually faced higher risk — and most of them weren’t couch potatoes; over 60% worked grueling jobs like farming or construction. Researchers point to the “physical activity paradox”: nonstop, necessity-driven labor doesn’t deliver the same heart benefits as a chosen workout, so rest may matter more for these workers.
Office workers and retirees, though, shouldn’t get comfortable — sitting eight-plus hours daily still carried elevated risk in the study.
