According to a new study published in the Annals of Internal Medicine, a sedentary lifestyle is bad for us. That we know. It leads to health problems and possibly an early death. But, according to this study, if you did sit for 12 or 13 hours a day (easily accomplished with a desk job) sitting for 30, 60, or 90 minutes at a time was associated with the highest risk of death. Sitting for less than 30 minutes at a time was associated with a lower risk. So, while a sedentary lifestyle is always bad, at least getting up every 30 minutes and moving around can be helpful.
