New research from Columbia University’s Mailman School of Public Health has found that people who attain higher levels of education age more slowly at the biological level and have a reduced risk of death.
Using data from the long-running Framingham Heart Study and an epigenetic tool called DunedinPACE, scientists observed that just two additional years of education were linked to a 2–3% slower pace of aging and a roughly 10% reduction in mortality risk.
The DunedinPACE clock measures biological aging by analyzing DNA changes in blood, offering a “speedometer” for how quickly the body is aging. Researchers found that individuals with higher educational mobility—those who achieved more education than their parents or siblings—tended to age more slowly and live longer.
This pattern held true across generations and within sibling comparisons, suggesting the effect isn’t just due to family background. The findings highlight education as a powerful tool for public health, offering benefits that go far beyond the classroom and deep into the biology of aging itself.
