The Link Between Multilingualism and Longevity
Recent research published in Nature Aging suggests that learning languages is one of the most effective ways to preserve brain health. Analyzing data from over 80,000 individuals aged 51–90, scientists discovered that monolingual people are twice as likely to experience accelerated aging compared to those who speak multiple languages. Using the Biobehavioral Age Gap (BAG) indicator, the study highlights a significant difference between biological health and chronological age based on linguistic ability.
Fitness for Neurons
As the global population ages and dementia cases rise, finding preventative measures is critical. The study reveals that the protective effect of language learning is "dose-dependent"—the more languages you know, the stronger the brain protection. Researchers explain that languages remain active in the background even when not in use, forcing the brain to constantly exercise executive functions, attention, and memory.
Conclusion
The authors argue that language acquisition should be treated as a tool for preventative health care rather than just a communication skill. To slow down brain aging effectively, the recommendation is simple: start learning a new language today.
