Too Much TV Raises Risk of Death
There's more evidence that spending too much time in front of the TV is bad for you.
Researchers at the National Cancer Institute say that sedentary behavior increases your risk for eight of the leading causes of death.
For their study, researchers analyzed more than 221,000 healthy adults between the ages of 50 and 71 years old until either their death or December 31, 2011.
Their findings, published in the American Journal of Preventive Medicine, showed that death risk increased with three to four hours of TV viewing per day, a finding that supports previous research. But this study revealed an associated increased risk in death from specific disease, including diabetes, influenza, pneumonia, Parkinson’s disease and liver disease.
Compared to those who watched an hour or less of TV per day, those who watched three to four hours were 15 percent more likely to die from any cause, and those who watched seven or more hours were 47 percent more likely to die during the course of the study.
Researchers controlled for potential contributors such as increased caloric and alcohol intake, smoking, and population health status.
Surprisingly, the negative effects of TV watching weren’t eliminated in people who remained active.
More research is needed to understand the link between TV viewing and mortality, and whether this risk applies to other forms of prolonged sitting such as driving or working at a desk.
