Recent research has found a link between sitting and an increased risk of developing endometrial, bowel and lung cancer.
For every extra 2 hours spent sitting each day, your risk of developing one of these cancers increases by between 6-10%.
In even more bad news, this effect does not seem to be affected by the amount of exercises you do. So even in those who are generally physically active, excessive sitting can increase cancer risk.
