What is the primary function of REM sleep?

The primary function of REM (Rapid Eye Movement) sleep is closely associated with emotional regulation and memory consolidation. During this stage of sleep, which is characterized by heightened brain activity and vivid dreaming, the brain processes and organizes information gathered during the day. It is crucial for integrating memories, particularly emotional memories, into our existing knowledge and experiences. This memory consolidation helps ensure that we can learn effectively and retain important information.

Research has shown that REM sleep plays a significant role in enhancing problem-solving skills and creativity, as well as regulating emotional responses. It is during this phase that the brain appears to work on synthesizing experiences, making associations, and promoting mental well-being, which underscores its importance in our overall cognitive function and emotional health.
