Sitting can be fatal! Researchers in Germany did a meta-analysis of 43 observational studies that included more than 4 million people. They found sitting is associated with a 24% increased risk of colon cancer, 32% increased risk of endometrial cancer, and a 21% increased risk of lung cancer. The bad news from this study is you cannot exercise away sitting's harmful effects. When adjustments were made for physical activity it did not erase the impact of sitting.
