The Claim
Multilingualism is associated with slower aging, and this association remains significant after adjustment for country-level factors including immigration, air quality, gender inequality, GDP, and political democracy.
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.
People who speak multiple languages tend to show signs of slower aging compared to those who speak only one language, even when accounting for differences in country-level factors such as wealth, pollution, and social equality.
See the scientific wording
The protective association between multilingualism and slower aging persists after adjusting for country-level factors including immigration, air quality, gender inequality, GDP, and political democracy, suggesting that the link is not explained by broader socioeconomic or environmental conditions.
Speaking multiple languages keeps the brain's networks more active and flexible, which helps the brain stay strong and work well longer as a person gets older.
What the research says
1 studyEven when scientists accounted for things like how rich a country is, how clean its air is, or how equal it is for men and women, people who speak more than one language still showed signs of aging more slowly. So it’s not just because they live in better places — speaking multiple languages seems to help on its own.
