One brisk walk a week could cut an older woman’s risk of early death by 70 percent, according to new research.
The study suggests that more physical activity, particularly at higher intensities, could lead to a ‘big’ increase in life expectancy among females in retirement age.
Researchers at Harvard University found light-intensity physical activity, such as a walking a dog, doing housework, or window shopping, did nothing to improve or worsen longevity.
Experts say this research should drive doctors to prescribe more intense physical activity to their patients, particularly older females.
