The Brain Benefits of Being Bilingual

By Dr. Mercola

More than half of the world’s population is bilingual or multilingual, which means if you only speak one language, you’re in the minority. This isn’t the case in the U.S., where only about 1 in 4 Americans speak a second language well enough to hold a conversation.1

In other areas of the world, however, numerous languages may be spoken in a small geographic area. And even if your home life doesn’t necessitate another language, in today’s digitally connected world, your business life might.

This language acquisition is not only valuable for communication, however — it offers health benefits as well.
