Americans’ sedentary lifestyle is raising their risk of several types of cancer - but just a 30-minute increase in activity each day is enough to make a difference, experts say.
A quarter of U.S. adults are sitting at desks, in cars, on couches and elsewhere for an average of eight hours a day, federal research says. And a study from Glasgow University this summer shows sitting for around 30 minutes, without getting up, each day could be linked to a higher risk of cancer.
