A 2-Minute Walk May Counter the Harms of Sitting

What they found was unexpected. A low-intensity activity like standing, by itself, had little effect on mortality risk. Those people in the study who spent a few minutes each hour engaged in such low-intensity activities did not show much if any decline in death risk, compared with those who sat the most.
But those who walked around after standing, replacing some of their sitting time with a light-intensity activity like strolling, gained a substantial benefit in terms of mortality risk.
In fact, if they replaced as little as two minutes of sitting each hour with gentle walking, they lowered their risk of premature death by about 33 percent, compared with people who sat almost nonstop.
