Two studies, one from Taiwan, and another that examined many previous studies, shows that even smaller amounts of exercise (~15 min/day) can prolong life and reduce heart disease. The protective effects of exercise are even greater for women than men.
Exercising 15 Minutes a Day Adds Three Years to Life, Study Says
Aug. 16 (Bloomberg) — Exercising for 15 minutes a day adds three years to a person’s life expectancy, according to the first study to show there’s a health benefit from even low levels of physical activity.
In a study involving more than 400,000 people, those who exercised for 90 minutes a week were also 14 percent less likely to have died after eight years than those who were inactive, researchers at Taiwan’s National Health Research Institutes wrote in The Lancet medical journal today. Every extra 15 minutes of exercise reduced the risk by a further 4 percent.
