Adults who are inactive much of the day may be more likely to die prematurely than people who don't sit around a lot, regardless of their exercise habits, a US study suggests.
People may also be less likely to die young if they break up sedentary time by moving around every half hour than if they remain seated for longer stretches of time without getting up, the study also suggests.
"We think these findings suggest that it is simply not enough to be active or move at just one specific time of the day, that is, exercise," said lead study author Keith Diaz of the Center for Behavioral Cardiovascular Health at Columbia University Medical Center in New York.
"We need to be mindful of moving frequently throughout the day in addition to exercising," Diaz said by email.
While previous research has linked excessive sedentary time to an increased risk of death, many of these studies relied on people to accurately recall and report how much they moved around and might not have painted a clear picture of the relationship between mortality and inactivity.
