London - nine-to-five office lifestyles are fuelling a ‘pandemic’ of inactivity and leading to 90,000 unnecessary deaths a year, researchers warn.
They say it raises the risk of dying early by up to 60 per cent – and that inactivity claims as many lives as smoking.
Adults who sit down for at least eight hours a day must do at least an hour’s daily exercise to undo all the harm, according to scientists at Cambridge University.
But even brief spurts of activity such as walking to the printer or going out for a coffee would help.
Their 20-year study, based on data from a million adults, published today in the Lancet, also estimates that 37 per cent of UK adults are completely inactive – meaning they spend less than 30 minutes a day on their feet
