The world economy could be boosted by as much as $100bn (£78bn) a year if employers successfully encouraged their staff to meet World Health Organisation guidelines on exercise, according to an analysis of the economic impact of activity.
Adding an extra 15 minutes of daily walking, or jogging a steady one kilometre each day, would improve productivity and extend life expectancy - leading to more economic growth, the study by the health insurance group Vitality and the think tank Rand Europe found.
The economic boost would come from lower mortality rates - in other words keeping more people alive, working and contributing to the economy for longer, the study’s authors said, and from employees taking fewer days off sick.
The WHO recommends that all adults should take at least 150 minutes of moderate exercise, or 75 minutes of vigorous exercise, a week. In a study last year it found that around 40 per cent of adults in the United States, 36 per cent in Britain and 14 per cent in China did too little exercise to stay healthy.
The Rand/Vitality study was based in part on data from about 120,000 people across seven countries. It then modelled and projected the potential economic benefits of increased physical activity globally and for 23 individual countries.
It also found that physically inactive 40-year-olds could increase their life expectancy, on average, by 3.2 years, by introducing 20 minutes of jogging a day.
