“Getting regular exercise is obviously an important part of staying healthy. But what about what we do with the rest of our time? A new study suggests that the time we all spend sitting is taking years off life expectancy in the U.S. Scientists are just beginning to investigate how sitting affects health, and early evidence has linked an excess of sitting time to all kinds of chronic maladies, particularly heart disease, diabetes and cancer. Now, a new analysis published in the British Medical Journal suggests that the life expectancy of the entire U.S. population could increase if Americans simply reduce the time they reduce channel-surfing on the sofa. Researchers looked at the results of five studies that explored the effects on nearly 167,000 people of sitting and watching television. Then they turned to national data collected by the U.S. Centers for Disease Control and Prevention on how much time Americans report sitting and watching TV.” w/ video
