It turns out having a desk job can increase your risk of death.
Sure, we all know that we should spend more time exercising. But why? In a new study, American Cancer Society researchers exploring the association of mortality and sitting time suggest that a sedentary lifestyle actually has specific biological consequences.
Researchers surveyed 123,216 healthy people (part of the American Cancer Society's Cancer Prevention II study in 1992) and found that people who spent their days sitting down have a higher risk of mortality.
During a time period of 1993 to 2006, researchers found that women who sat down for at least 6 hours a day were 37 percent more likely to die when compared to women who sat for 3 hours a day during the time period studied. For the same time period, men who sat down for 6 hours a day were 18 percent more likely to die than their standing counterparts.
"Several factors could explain the positive association between time spent sitting and higher all-cause death rates," Dr. Alpa Patel said in a statement. "Prolonged time spent sitting, independent of physical activity, has been shown to have important metabolic consequences, and may influence things like triglycerides, high density lipoprotein, cholesterol, fasting plasma glucose, resting blood pressure, and leptin, which are biomarkers of obesity and cardiovascular and other chronic diseases."
