Understanding Your Sleep Architecture
The Four Stages of Sleep
Stage 1: Light Sleep
Transition phase where brain waves begin slowing down from wakefulness.
Stage 2: True Sleep Onset
Body temperature drops and heart rate slows as sleep deepens.
Restorative Sleep Phases
Stage 3: Deep Sleep
Critical for physical recovery and immune function.
REM Sleep
Essential for memory consolidation and emotional processing.
