Learning a new language isn’t just great for your career; it also keeps your brain young and active. Recent research shows that multilingualism helps protect the brain from ageing and builds confidence in communication.
A study by Chilean neuroscientist Agustín Ibáñez, published in Nature Aging and reported by Maarten Keulemans in de Volkskrant, found that people who speak multiple languages have up to 15% less risk of early brain ageing for every extra language they master.
Even regional or minority languages, such as Frisian, make a difference. According to the researchers, multilingualism gives the brain a cognitive reserve, a mental buffer that helps protect against ageing and diseases like dementia.
Professor Merel Keijzer from the University of Groningen confirms that the biggest benefits come from actively using multiple languages. Switching between them keeps the brain flexible, like a workout for your mind.
At Taleninstituut Nederland, we see this every day: learning a new language helps you communicate more confidently at work and in daily life. Whether it’s in meetings, client conversations, or small talk with colleagues, language skills make collaboration easier and strengthen your professional presence.
Every new language you learn is more than just a skill; it’s an investment in your brain, your confidence, and your future.
