Previous studies have shown a link between time spent sitting and cancer, diabetes, heart disease, and early death, even among those who regularly exercise. An analysis of 26 published studies found the most effective interventions for reducing sitting time were promoting sit-stand desks, encouraging people to keep a record of how much time they spend sitting each day, setting individual goals for limiting sitting time, using alarms to encourage people to get up and move around, and educating people on the health consequences of sitting too much.
