Scientists discovered that adopting five or more healthy lifestyle practices boosted life expectancy even in those over the age of 80 and notably, people with chronic health conditions.
Osaka University researchers discovered that adjusting lifestyle behaviors can have a significant impact on lifespan, even in those with chronic health issues.
Ever since the beginning of civilization, humans have wanted to live longer. Whether it be the Fountain of Youth, Gilgamesh’s secret plant of immortality, or the elixir of life, the idea of immortality is incredibly prevalent in humanity’s oldest and most well-known stories.
Unfortunately, immortality is only a myth. The average lifespan in the United States is nearly 79 years and it is unlikely to increase dramatically in the next few years. Still, scientists have been researching how to increase our longevity and have found promising results.
Idioms and proverbs emphasizing the significance of good health have been passed down for centuries. Many emphasize how closely health is linked to happiness and the ability to live a full and joyful life.
A study published in Age and Ageing on May 11, 2022, by The Japan Collaborate Cohort (JACC) Study group at Osaka University examined the impact of adjusting lifestyle habits on life expectancy from middle age onwards. The researchers discovered that adopting five or more healthy lifestyle behaviors boosted life expectancy even in those over the age of 80, and, importantly, including those with chronic conditions.

The study continued until December 2009, by which time 8,966 individuals had died. The study’s primary author, Dr. Ryoto Sakaniwa said. “The results were very clear. A higher number of modified healthy behaviors was directly associated with great longevity for both men and women.” The lifetime gains were highest for reducing alcohol intake, not smoking, losing weight, and increasing sleep, adding up to 6 years of life for healthy 40-year-olds.
This benefit was prominent even among older individuals (80 years or more) and those with one or more major comorbidities including cancer, cardiovascular disease, hypertension, diabetes, and kidney disease, and in each life stage from middle age onwards. “This is a particularly important finding given that the prevalence of chronic diseases has increased globally and is a major cause of death in older populations,” says Senior author, Prof. Hiroyasu Iso. This is one of the first studies to measure the impact of improvements to health behavior among older individuals in a country with a national life expectancy achieving almost 85 years.
