Going for a brisk walk for just 22 minutes once a day may be enough to offset the negative health effects of sitting too much, research suggests.
Sedentary lifestyles are among the leading causes of ill health worldwide. Millions of people who sit for long periods, watching TV or working at a computer, for example, are more likely to die earlier.
But moderate-to-vigorous physical activity can eliminate this increased risk from being sedentary, according to the study, published in the British Journal of Sports Medicine.
Experts examined data for 11,989 people aged over 50, half of whom were women, from Norway, Sweden and the US. People in the study had worn activity trackers that measured their moderate-to-vigorous physical activity (MPVA).
