Circadian Rhythm Sleep Disorders
Not insomnia — misalignment. The clock runs fine, it's just set to the wrong time relative to the world around it. Delayed and advanced phase disorders sit at opposite ends; shift work forces the mismatch externally.
This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.

the one idea
why this one carries the topic.
Sleep isn't the brain switching off. It's the brain running a different program on a schedule — and breaking the schedule degrades everything else.
The internal body clock is functioning normally but is out of sync with the external environment or required sleep-wake schedule.
what examiners catch — Students confuse these disorders with insomnia when the issue is timing misalignment, not inability to sleep at all. *2. Consciousness as a Continuum* Consciousness isn't on or off. It runs from total awareness through daydreaming to deep sleep and anaesthesia — and sleep is a naturally occurring altered state, not an absence of one.
what you leave with
four things, not forty.
DSPS: sleep onset and waking both much later; common in adolescence
ASPS: sleep onset and waking both much earlier; more common with age
Shift work disorder: work schedule fights the internal clock
The rhythm itself is intact — its alignment isn't
what's underneath
nothing here is a standalone fact.
knowhere maps every concept to what it rests on and what rests on it — 1 underneath this one, 1 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
