An observational study in the BMJ Open found an association between the amount of time spent seated every day to longevity. A before the headlines analysis was also sent out to accompany comments.
Prof David Spiegelhalter, Professor of the Public Understanding of Risk at the University of Cambridge, said:
“This is a study of populations, and does not tell you personally what the effect of getting off the sofa might be. It seems plausible that if future generations moved around a bit more, then they might live longer on average. But very few of us currently spend less than 3 hours sitting each day, and so this seems a very optimistic target.”
