Side Effects Of Sitting Too Long On Computer

By now, youve probably already heard that
sitting all day is bad for you, but exactly how
many hours of sitting may be too much? New
research says reducing the amount of sitting to
less than 3 hours a day can increase life
expectancy by 2 years. Participants in the
National Health and Nutrition Survey reported
their sedentary habits, including how many hours
they spend sitting (e.g., using the computer and
watching TV). The researchers eliminated data for
patients with existing diseases (who might be
more prone to sitting a lot) and then folded in
mortality risk into their meta- analysis.

The results indicate that US life expectancy
drops by 2 years when people sit for more than 3
hours a day, and another 1.4 years for watching
TV more than 2 hours a day. Researchers Peter T
Katzmarzyk and I-Min Lee conclude that reducing
the amount of time you sit, including TV viewing
time, can potentially increase life
expectancy. While that conclusion isnt really
new news (a previous Australian study linked TV
watching with reduced life expectancy), spending
less than 3 hours in a chair is a new goal.
Its clear that the fewer hours you spend
sitting, the better (even if you do exercise
regularly).
