Once Again, Watching TV Proves Unhealthy

The Journal of the American College of Cardiology has done it again. In a recently conducted study, they found that spending too much leisure time in front of a television can and will affect the chance of heart disease and premature death.
The most fascinating part about the whole study is that these results are regardless of how much exercise one accomplishes. The study analyzed the association between screen time and fatal/non-fatal cardiovascular attacks. According to Dr. Emmanuel Stamatakis from the Department of Epidemiology and Public Health at The University College London, UK, boldly proclaims that people who watch a lot of television are more likely to die of “any cause,” and suffer from heart-related issues. According to him and his team that conducted the research, those who spent at least two hours in front of a screen each day were at greater risk.
This study consisted of 4,512 adults, all of whom responded to the 2003 Scottish Health Survey. During a period of 4.3 years, there were a total of 325 all-cause deaths and 215 cardiac happenings. The statistics are astounding!

These relations were autonomous of traditional external risk factors such as smoking, BMI, hypertension, social class, as well as fitness. These results have prompted a spread of advocacy for public health guidelines that promote longer periods of activity and standing, outside of work. This translates to habitual things like watching tv, playing video games, etc…
These test were very similar to the studies that pinpointed prolonged sitting as a direct factor in inflammation and problems in metabolism, and can be directly tied into the simple cliché of being lazy is unhealthy. But it was also found that inherent biological factors also played a role in determining the risk of heart problems. Some of these included:
CRP (C-Reactive Protein)
BMI (Body Mass Index)
High-Density Lipoprotein Cholesterol
All of which suggest that deregulation and inflammation of lipids may be one pathway through which prolonged sitting increases the risk for cardiovascular events. People who spent more than four hours a day watching TV has a CRP that was twice as high as those who didn’t.
Although it’s likely that people will not stop watching TV for extended periods because of this, it is recommended to “turn it back a notch.” Reasonably so (and Dr. Stamatakis will agree), we should attempt to figure out what extended periods of sitting do to the body in the long and short term; find out if exercise can alter these consequences, and ultimately how to alter our current lifestyles!
