What pattern of sleep typically occurs after Non-REM sleep?

Deep dreamless sleep
Light sleep
REM sleep
Shallow sleep

The correct answer is: REM sleep

The correct answer is REM sleep, which follows Non-REM sleep in the sleep cycle. Understanding the sleep stages is crucial as they play a significant role in physical and mental health. Non-REM sleep consists of several stages, including light sleep and deep sleep. In these stages, the body physically recuperates, and restorative processes occur. After completing one cycle of Non-REM sleep, the body transitions into REM sleep. This stage is characterized by rapid eye movement, increased brain activity, and vivid dreams, making it essential for cognitive functions like memory consolidation and emotional regulation. The alternation between Non-REM and REM sleep constitutes a cycle that typically continues throughout the night. The combination of both types of sleep contributes to overall restfulness and well-being. This understanding underscores the importance of both Non-REM and REM stages in a healthy sleep architecture.
