The Sleep Cycle: From Wakefulness to Deep Sleep and Back

An illustrative guide to how broad brainwave patterns are commonly associated with different sleep stages. This resource is educational only and is not medical advice.

Sleep-stage cycle pathway A looping pathway moving from Wake to N1, N2, N3, REM, and then back toward wake-like activity.
Wake Baseline before sleep onset.
Simplified calm brain illustration A simplified warm-neutral brain illustration with soft shading.

Broad patterns only. Brain activity changes continuously through the night; these ranges are simplified anchors for education, not a diagnostic sleep model.
