Just 15 minutes of exercise a day can increase your life expectancy by three years and reduce the risk of dying by 14 per cent, according to research.
And every additional 15 minutes of daily exercise reduces the risk of death further, by four per cent, the study found.
Past research has shown that regular exercise can lower risk of heart disease, stroke, type 2 diabetes, dementia, brittle bones and some cancers. Exercise can also help to reduce stress, boost mood and improve sleep.
But the minimum amount of exercise needed to improve a person's health prospects is ill-defined.
Currently, the UK government recommends that adults should try to fit in 150 minutes of 'moderate intensity' physical activity every week.
But the latest study, published online in the Lancet, suggests people can still reap the health benefits of exercise by doing substantially less than this.
Researchers at the National Health Research Institutes, Taiwan, tracked the health of more than 400,000 Taiwanese men and women between 1996 and 2008, who took part in a medical screening programme. The participants filled in questionnaires about their leisure-time physical activity, including exercise duration and intensity.



Based on their responses, the participants were placed into one of five 'exercise volume' groups: inactive, low, medium, high, or very high activity.
People in the low volume group exercised, on average, for 92 minutes a week, or about 15 minutes a day.
When compared with those in the inactive group, those in the low volume group were 14 per cent less likely to die from any cause, 10 per cent less likely to die from any cancer and had an increased life expectancy of three years.
