15 Minutes Daily Exercise Adds 3 Years To Life

Even if the exercise was of light intensity just 15 minutes of exercise a day was found to extend life expectancy 3 years among Taiwanese.

HOUSTON -- Taiwanese who exercise for 15 minutes a day, or 92 minutes per week, extended their expected lifespan by three years compared to people who are inactive, according to a study published today in The Lancet.

"Exercising at very light levels reduced deaths from any cause by 14 percent," said study senior author Xifeng Wu, M.D., Ph.D., professor and chair of The University of Texas MD Anderson Cancer Center Department of Epidemiology. "The benefits of exercise appear to be significant even without reaching the recommended 150 minutes per week based on results of previous research."

All the way up to 100 minutes of exercise per day more exercised translated into additional reduction of risk of death.

Lead author Chi-Pang Wen, M.D., of the National Health Research Institutes of Taiwan, and colleagues also found that a person's risk of death from any cause decreased by 4 percent for every additional 15 minutes of exercise up to 100 minutes a day over the course of the study. Those exercising for 30 minutes daily added about four years to life expectancy.

If you live just a mile from some place you now drive to consider walking instead. Want to have a conversation with a friend? Do it while walking.

15 minutes daily exercise adds 3 years to life?
Then exercising 24 hours a day would add 144 years.
Such a deal.

So by taking perhaps ten years out of your life to exercise, you gain three back?

There are other benefits to exercising but the raw math on this one is...interesting.

Fantastic! So, now I can exercise for 15 minutes, then watch TV for six hours and call it a wash!

15 minutes/day for 96 years would equal one year of total exercise time. Not a bad deal.

Did they take prior health risks into account? correlation doesn't equal causation. Maybe people don't exercise because they are unhealthy and not the other way around.

Yahoo! Three more years of drooling into a bib in a government rest home.

Why don't you get back to us when you actually do the raw math? As dbp accurately implies, if you exercise for 15 minutes a day, then for it to add up to ten years would take over 960 years.

PacRim Jim, congratulations on saving some of your precious seconds by reading only the headline, but couldn't you have double-checked your math? (24h gives 288 years.)

If y'all are going to go for very obvious snark, at least get the basic arithmetic right.
