Sleep Apnea
Sleep restriction transiently increases daytime sleepiness, so someone with untreated sleep apnoea should not self-administer it — that stacks two things both cutting into alertness. CPAP first, then CBT-I.
Caffeine + L-Theanine
The sleep-hygiene list is not wrong — it removes obvious obstacles, and with a 5-6 hour caffeine half-life an afternoon cut-off makes sense. But note what it is in most CBT-I trials: the control arm. Hygiene alone does not treat chronic insomnia.

Sleep Architecture & Sleep Debt
CBT-I's stimulus control is not endurance: it rebuilds the bed as a sleep cue, working on sleep pressure and conditioning rather than deepening any one sleep stage directly.
Insomnia
CBT-I is the A-level first line for chronic insomnia, not a sleep tip: stimulus control rebuilds the bed as a sleep cue, sleep restriction compresses fragmented sleep back into a block. Reaching for drugs first inverts the order.

Why behavioral, not pills, is first-line

Stop 1/6

为什么一线是行为而不是药

If you sleep badly for a long stretch, the first instinct is usually 'take something' — melatonin, an OTC sleep aid, or a Z-drug from a doctor. But the first-line treatment for chronic insomnia in every major guideline is not a drug — it is a behavioral/cognitive program: CBT-I (Cognitive Behavioral Therapy for Insomnia).

This island is the 'how to treat it' of the sleep cluster — its division of labor with the other two islands is clean:

`sleep-architecture` is how the building of sleep is constructed (N3 deep sleep / REM / the two-process model) — the 'why'`insomnia` is how insomnia is classified and diagnosed, and what the drug risks are — the 'what it is'This island is how the genuinely effective non-drug intervention works — the 'how to do it,' taking the five CBT-I components mentioned in `insomnia` and unpacking each one's mechanism
How blunt the guidelines are

The American College of Physicians (ACP) 2016 guideline (Qaseem et al.): explicitly recommends that all adults with chronic insomnia receive CBT-I as the initial treatment, with medication only as an add-on 'when CBT-I alone is insufficient,' decided through shared decision-making weighing benefits and harms. This is an official document that strongly recommends CBT-IThe American Academy of Sleep Medicine (AASM) 2021 clinical practice guideline (Edinger et al.): gives a strong recommendation (high certainty) for multicomponent CBT-I in adults with chronic insomnia
Why behavioral and not a pill — the one-line mechanism

A drug (sedation) treats the surface — 'I can't sleep right now.' CBT-I treats the maintaining mechanism — 'why won't this insomnia stop' (the hyperarousal model, next scene). The former covers the symptom; the latter dismantles the root — which is exactly why drugs rebound on discontinuation while CBT-I's effects persist after treatment ends (Trauer 2015, later).

One honest line: CBT-I is not 'toughing it out without drugs' — it is a treatment that is more causal and better value long-term than drugs. It is not mysterious and is very low-risk; the real barrier is availability — most people with insomnia were never told it exists (detailed in the last scene).
