Understanding Sleep Patterns
Sleep patterns include various stages that our bodies cycle through each night. The main stages are REM (Rapid Eye Movement) and non-REM sleep, which consists of three sub-stages. Non-REM stages go from light sleep (Stage 1) to deep sleep (Stage 3).
REM Sleep
REM sleep is vital for cognitive functions like memory and learning. During REM, our brain activity increases, breathing becomes irregular, and dreams are most vivid. According to Sleep Foundation studies, REM sleep usually accounts for about 20-25% of total sleep in adults.
Non-REM Sleep
Non-REM sleep features three stages:
- Stage 1: Light Sleep
This initial stage includes drifting in and out of sleep and makes up about 5-10% of total sleep time. It’s easy to wake up during this phase. - Stage 2: Moderate Sleep
This stage stabilizes sleep patterns and covers around 45-50% of total sleep time. Body temperature drops and heart rate slows. - Stage 3: Deep Sleep
This stage supports physical recovery and growth. It covers about 15-20% of total sleep time and is hard to wake up from during this phase.
Importance of Sleep Cycles
Each cycle, comprising both REM and non-REM stages, repeats approximately every 90 minutes. Healthy sleep patterns include 4-6 complete cycles per night.
Tracking these cycles using wearables provides insights into the duration and quality of each sleep stage. This data is crucial for evaluating sleep health and making necessary adjustments to improve overall well-being.
