PEOPLE who walk for 10 minutes once a week are 18 per cent less likely to die within a decade, a study found.
The risk of a stroke or heart attack for over-40s also fell by 12 per cent.
Researchers studied activity levels of 88,140 Americans aged 40 to 85 over an 11-year period, and linked them to registered deaths to the end of 2011.
People who did 150 to 299 minutes of activity a week reduced their risk of death by 31 per cent, they found.
Those who did 1,500 minutes or more almost halved it at 46 per cent, and had a 33 per cent reduced risk of cardiovascular disease.
Dr Bo Xi of Shandong University in China said gentle exercise was beneficial but added: “People short of time should consider more vigorous activities.”
