We could learn vocabulary while we are sleeping. This is great news for language learners. Researchers said we can learn new information while sleeping and use this information later. The researchers did tests using new words and their translations. The researchers said our sleeping brain is active.

The language areas and memory in the brain work after a person wakes up. These areas remember vocabulary when we sleep. During deep sleep, our brain is active for about half a second. This is when our brain could learn vocabulary. More research is needed to be sure that we can learn vocabulary when we are sleeping.
