It’s one of life’s truths: Being bilingual or multilingual can only be considered a good thing. The ability to travel seamlessly in another country; to interact with people you wouldn’t otherwise be able to communicate with; to really understand and immerse yourself in another culture, whether it be your own or another’s; and on the most trivial level, to order off a menu and truly know what you’re ordering.
But aside from all these reasons, there is a multitude of research showing how speaking more than one language is also good for your health — particularly, the health of your brain. Here’s where the bilingual among us have an advantage:
They have better “cognitive flexibility.”
Older adults who have spoken two languages since childhood seem to have better cognitive flexibility — meaning, they are better able to go with the flow in the face of a new or unexpected circumstance — than adults who only speak one language, according to a Journal of Neuroscience study. The study involved having participants complete a cognitive flexibility task; while monolingual and bilingual adults were both able to complete the task, the bilingual adults did it more quickly and certain parts of their brains used less energy to do so.
Their brains stay sharper in old age.
And this is true even for people who learned a second language later in life, according to a recent study in the Annals of Neurology. The study involved following native English speakers who took an intelligence test when they were age 11, and then again when they were in their early 70s. People who spoke two or more languages had greater cognitive abilities — particularly in general intelligence and reading — from their baseline, compared with those who only spoke one language.
They look at certain words in a different way than their monolingual counterparts.
People who speak two languages may process certain words faster, particularly if the word has the same meaning in both languages, according to a Psychological Science study. Using eye-movement technology, researchers found that bilingual people spend less time looking at “cognate words” — words that have the same meaning in two languages, such as the word “sport” for both English and Dutch — which suggests their brains need less time to process the word, Scientific American reported.
