The Claim
In adults aged 51–90 across 27 European countries, residence in nations with higher rates of multilingualism is associated with a 54% lower odds of accelerated biological aging and a 30% lower risk of developing accelerated aging over time, independent of socioeconomic, physical, and sociopolitical factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults aged 51–90 living in countries where more people speak multiple languages have a 54% lower odds of accelerated biological aging and a 30% lower risk of developing accelerated aging over time, after accounting for socioeconomic, physical, and sociopolitical factors.
See the scientific wording
In a cross-sectional and longitudinal analysis of 86,149 adults aged 51–90 across 27 European countries, individuals residing in countries with higher rates of multilingualism showed a 54% lower odds of accelerated biological aging (odds ratio = 0.46) and a 30% lower risk of developing accelerated aging over time (relative risk = 0.70), independent of socioeconomic, physical, and sociopolitical factors, suggesting that national multilingual environments are associated with slower aging trajectories.
Speaking multiple languages keeps the brain more active and connected, which lowers harmful stress chemicals in the body and reduces damage to cells over time, slowing down aging.
What the research says
1 studyPeople in countries where many speak more than one language tend to age more slowly, even when you account for things like income and healthcare. The study found they’re less likely to show signs of fast aging.
