Understanding Sleep Architecture and Technology

The Science of Sleep Stages

Non-REM Sleep Stages

Stage 1 (N1) - Light Sleep:

• Duration: 5-10% of total sleep time
• Characteristics: Transition from wake to sleep, easy to wake
• Brain waves: Alpha and theta waves
• Function: Initial relaxation and preparation for deeper sleep

Stage 2 (N2) - Stable Sleep:

• Duration: 45-55% of total sleep time
• Characteristics: Sleep spindles and K-complexes on EEG
• Function: Memory consolidation, brain maintenance
• Temperature: Body temperature begins to drop

Stage 3 (N3) - Deep Sleep/Slow Wave Sleep:

• Duration: 15-20% of total sleep time (higher in younger individuals)
• Characteristics: Delta waves, difficult to wake from
• Function: Physical recovery, immune function, growth hormone release
• Importance: Most restorative sleep stage for physical health

REM Sleep
