Exercise Extends Lifespan

Regular exercise can add years to your life! In a new study scientists used information from several national data resources to estimate the impact of exercise on longevity. Being active added more than 2 years to the life expectancy of white men at age 20. Women at that age gained even more, roughly 3 years added to their lifetime. African-American women who exercised at least 2 and a half hours a week got the biggest boost. They extended their probable lifespan by 5 and a half years.
The authors conclude that leisure-time physical activity is an excellent investment of time and effort. They estimate that for every hour of moderate physical activity, an American adult will gain between 2 and 5 additional hours of life. Exercising vigorously brings even greater rewards. Anticipate anywhere from 5 to 11 extra hours of life for every hour of vigorous physical activity.

Not only can exercise boost longevity, it can also improve brain function. Our interview several years ago with Dr. John Ratey reviewed the evidence that exercise benefits cognition both in children and in older people. Finding an activity that you love, whether cycling, swimming or dancing, increases the likelihood that you will stick with it for at least 30 minutes a day most days of the week.
