Running for an hour is equivalent to seven hours added to your life, a new study revealed.
The study, which was conducted at the Cooper Institute in Dallas, Texas for three years, found that running trumps all other forms of exercise in terms of considerable impact on life span.
The results of the study were published last month in Progress in Cardiovascular Disease, and also looked at findings from other recent studies which focused on relationships between exercise and lifespan.
The results estimated that running adds more time to people's lives than it takes up, even if they smoke, drink and are overweight. The average reported running time was about two hours weekly, Cooper Institute found, which means that over about 40 years, a runner might only run less than six months total.
Study co-author Dr. Duck-chul Lee told The New York Times that the additions are "not infinite" and the added years to longevity are capped at around three extra years.
Researchers also found that other kinds of exercise also help with lengthening lifespans, but not to the same degree as running. Lee said activities like walking and cycling typically lessen the risk of premature death by about 12 percent.
Dr. Lee said it's unfounded why running has such a substantial relationship to lifespan, but that one might point to its effect on lowering high blood pressure and getting rid of extra body fat.
