People who predominantly sit at work would need to engage in an additional 15 to 30 minutes of physical activity per day to mitigate an increased risk of mortality, new research has revealed.

The study involving 481,688 individuals over a mean follow-up period of 12.8 years found that individuals, who predominantly engaged in sitting at work, exhibited a higher risk of mortality from all causes (16 per cent) and cardiovascular disease (34 per cent) compared with those who predominantly did not sit.
