Exercise Lengthens Life Span, TV Shortens It

I was going to file this under News You Already Knew, but it didn’t really fit, so I’m gonna put this under the heading of Studies Confirming the Obvious:

Today we learn that the results of a new study “suggests” (gotta love how studies can make suggestions) that when people get even just 15 minutes of exercise a day, they can reduce their ‘mortality risk’ by 14%:

A study in Taiwan, reported in The Lancet, tracked more than 400,000 men and women over 12 years, and showed significant benefits from 15 minutes a day or 90 minutes a week of moderate exercise such as brisk walking.

And then we learn from another study that every single hour of TV watched after the age of 25 may shorten your lifespan by 22 minutes:

“Logically we know that physical activity is good for health and so it’s not so strange that the reverse is not so good.”

No word yet on whether or not watching TV while on the exercise bike counts for or against the length of your lifespan. Or if it depends on if you’re watching someone else exercise on that TV.

    Technically speaking, I’d say an hour’s worth of TV shortens your life by an hour 🙂

      Totally, so it’s more like an hour and 22 minutes…

    We spend so much time and effort to bring them here and then we put them in front of TV. Thanks for posting on this important issue. Yes, getting off the couch and computer is healthy and an investment for life!
