- NREM sleep has three stages, namely N1, N2, and N3. N1 is the transition from wakefulness to sleep, N2 is a slightly deeper sleep, and N3 is deep sleep or slow-wave sleep (SWS), crucial for physical restoration and growth.
- REM sleep is associated with vivid dreaming and rapid eye movements. It occurs approximately 90 minutes after falling asleep and is crucial for cognitive functions, memory consolidation, and emotional regulation.
- A typical night’s sleep consists of multiple sleep cycles. In the first half of the night, deep sleep stages (N3) are more prominent, while REM sleep becomes more dominant in the later cycles.
- Each sleep stage is characterized by distinct patterns of brain activity. For instance, during REM sleep, brain activity is similar to wakefulness, while deep N3 sleep shows slow delta waves.
- The proportion of time spent in each sleep stage changes across the lifespan. Infants spend a significant amount of time in REM sleep, while deep N3 sleep decreases with age.
