People who speak two or more languages are half as likely as those who speak only one to age prematurely relative to their biological age, concludes a study conducted in 27 European countries. This benefit is as important as physical activity and quality sleep.

Is learning multiple languages at least as important a protective factor against aging as physical activity? New research conducted in 27 European countries, including France, demonstrates that the brains of multilinguals, bilinguals, and more mature individuals age more slowly than those of monolinguals. While these results currently reflect non-pathological aging, they are likely also relevant to protection against age-related diseases. Individuals with accelerated aging typically exhibit the same vulnerability patterns that predict chronic diseases such as diabetes, dementia, or hypertension, while delayed aging reflects greater resilience and preserved functional capacity." , confirms to Science and Future neuroscientist Agustín Ibáñez, who led this international work published in the journal Nature Aging.
