How does REM help in memory?

REM (Rapid Eye Movement) sleep plays a crucial role in memory consolidation, which is the process of stabilizing and integrating new information into long-term memory. During REM sleep, the brain is highly active, and it is believed that this phase helps in organizing and processing memories, particularly emotional and procedural information. Studies have shown that individuals who experience adequate REM sleep tend to perform better on tasks requiring recall and problem-solving. Overall, REM sleep enhances cognitive functions by facilitating the brain's ability to form and retain memories.
