TV Shortens Lifespan, Australian Study Finds

January 12, 2010

Australia (ChattahBox) – An Australian study has found a link between increased television viewing and cardiovascular related diseases.

This would seem like a no brainer for most: watch a lot of TV, you probably don’t exercise enough, you are higher risk for obesity and cardiovascular disease.

But what was once a matter of common sense has now been confirmed by scientific proof.

The study was performed by the Australian Diabetes, Obesity and Lifestyle Study.

It found that every hour of TV increases your risk of cardiovascular disease by 18%, 11% by all other causes of death, and 9% of cancer.

“What we showed was that irrespective of a person’s exercise level, sitting for four or more hours watching television was linked to a significant increase in risk of death compared to watching lower amounts of TV,” Dr. David Dunstan explained of their results, which showed an 80% increased chance of death by cardiovascular disease, or 46% of death itself, for those that watched 4 or more hours a day.

“The message here is that in addition to promoting regular exercise, we also need to promote avoiding long periods of sitting, such as spending long hours in front of the computer screen.

“When we’re in that sitting posture, we’re not using our muscles, and we know from extensive evidence that muscle contractions are important for the body’s regulatory processes, such as the ability to break down glucose and use it as energy.”

The study has been published in the American Heart Association’s journal, Circulation.
