Few medical studies have analyzed the relationship between sitting and total mortality. But a large (123,216 individuals) new study from the American Cancer Society found that women who sit for more than six hours/day were 37 percent more likely to die (over the 13-year study period)—and 10 percent more likely to get cancer—than those who sat less than three hours/day. Surprisingly, the “sitting risk” was lower for men: six-plus-hour-a-day male sitters were 18 percent more likely to die, but the cancer risk was not considerably higher.

Check out the findings—and also see just how deadly combining sitting with a lack of physical activity is.
