A new study of around 8,000 middle-aged and older adults found that swapping a half-hour of sitting around with physical activity of any intensity or duration cut the risk of early death by as much as 35 percent. The findings highlight the importance of movement—regardless of its intensity or amount of time spent moving—for better health.
Of course, more exercise is still better. The study found that longevity benefits compounded as physical activity piled up; an hour of exercise conferred twice as many benefits as half an hour.
The study was published online in the American Journal of Epidemiology.
