Sleep Architecture
Sleep is a highly structured, 90-minute cyclical progression through four distinct neurological phases.
NREM Stage 2
Characterized by sleep spindles and K-complexes. Acts as a gatekeeper.
NREM Stage 3
Delta waves. Highly restorative physical repair phase.
Phase Distribution
| Phase | Percentage |
|---|---|
| N1 / Light | 5% |
| N2 / Core | 50% |
| N3 / Deep | 20-25% |
| REM | 20-25% |
Clinical FAQ
Can I skip phases?
No, they are strictly sequential. Alcohol can suppress REM entirely, however.
