Sitting and watching TV too much up risks of cancer

How many hours a day do you spend in sitting and watching the TV? This behavior may be very dangerous, and not only for the obvious consequences a sedentary lifestyle can bring (overweight or obesity). As a matter of fact, “prolonged TV viewing and time spent in other sedentary pursuits is associated with increased risks of certain types of cancer”, assess researchers at the Universität Regensburg, Germany, in their study published in the Journal of the National Cancer Institute.

The scientists put together data from 43 observational studies which involved over 4 million people, including 68,936 cancer cases. Thereafter, they divided sedentary behavior into three categories — TV viewing time, occupational sitting, and total sitting time. At last, they calculated risks for many cancers in correlation to the level of sedentary time. The findings show that any two-hour of sitting time increases the risk for lung cancer by 6%, for colon cancer by 8% and for endometrial cancer by 10%.

Furthermore, it doesn’t matter whether you make regularly physical activity, as sport doesn’t seem to positively affect health, by producing a sort of “counter-balancing effect”.
