The Claim
In adults aged 51–90 across 27 European countries, speaking two or more additional languages is associated with a 49% lower odds of accelerated aging (odds ratio = 0.51) and a 20% lower risk of developing accelerated aging over time (relative risk = 0.80), with effects increasing with age.
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 in 27 European countries who speak two or more additional languages have a 49% lower odds and a 20% lower risk of accelerated aging compared to those who do not, and this difference becomes larger with increasing age.

In adults aged 51–90 across 27 European countries, speaking two or more additional languages is associated with a 49% lower odds of accelerated aging (odds ratio = 0.51) and a 20% lower risk of developing accelerated aging over time (relative risk = 0.80), with effects becoming more pronounced in older age groups, suggesting a cumulative protective association between multilingualism and aging.
Regularly using multiple languages strengthens connections between brain regions that manage attention, memory, and decision-making. This makes the brain more efficient at handling tasks and resisting damage over time, so it ages more slowly.
What the research says
1 studyPeople who speak two or more languages besides their native language tend to age more slowly, and this benefit gets stronger as they get older — and this study found exactly that in a huge group of adults across Europe.
