Sleep hygiene is the set of repeated cues that make sleep easier or harder: stimulant timing, light exposure, schedule regularity, bedroom conditions, evening stimulation, naps, and what the bed is used for while awake. These habits do not force sleep on command, but they shape the conditions that decide whether the body and mind are ready to settle.

A rough night often begins long before bedtime. Afternoon caffeine can keep sleep pressure from building cleanly. Weak morning light can leave the body clock less anchored. A long recovery nap can make bedtime feel too early, while late scrolling or clock checking can teach the brain to stay alert in the very place where sleep should feel automatic.

Sleep pressure: The drive to sleep that builds with time awake. Late or long naps can spend some of that pressure before night.
Circadian timing: The body-clock pattern shaped by wake time, morning light, darkness, and regular schedules.
Arousal load: Mental or physical activation near bedtime, such as interactive screens, stressful checking, or intense late exercise.
Bed association: The learned link between bed and sleep. Work, planning, watching, or scrolling in bed can weaken that cue.

Sleep-hygiene reviews work best when they compare the whole routine rather than one rule in isolation. A person may avoid screens but keep an irregular wake time, or make the room darker while drinking caffeine too late for their own sensitivity. The useful question is which repeatable cues add enough friction that a small, steady experiment is worth trying.

Better habits can support sleep, but they are not a diagnosis or treatment. Persistent insomnia, loud snoring, breathing pauses, severe daytime sleepiness, unsafe drowsiness, pain, medication effects, anxiety, depression, and shift-work strain need broader review. A habit audit is a starting point for sorting cues, not a verdict on sleep health.

The strongest sleep-hygiene plans protect the anchors that are already helping while changing only a few gaps at once. Too many simultaneous changes can make the next result harder to interpret, even when the changes are sensible on their own.

How to Use This Tool:

Use the checker as a snapshot of the routine you actually repeat. Honest ordinary-night answers are more useful than a perfect profile that only happens once in a while.

Start with Preset. Custom keeps manual answers, while Balanced baseline, High-friction pattern, Weekend drift pattern, Wired-and-tired evenings, and Optimized routine load editable starting profiles.
Set each habit field by the usual pattern. The field preview should match your real caffeine timing, alcohol timing, evening screens, schedule consistency, nap pattern, bedroom environment, clock checking, bed use, exercise timing, and morning light.
Open Advanced only when one domain should count more or less for the question you are testing. Substance timing, circadian anchor, arousal loop, and bedroom load weights can be set from 0.75x to 1.50x.
Choose Focus queue size, Reset pace, and Retest window. Queue size can be 2 to 6 items, pace can favor gentle, steady, or focused ranking, and retest windows run from 7 to 21 days.
Read the Sleep Friction Snapshot first. The friction band, total score, primary driver, top gap, protected count, queue count, and retest days tell you whether the profile points to maintenance, a targeted reset, or broader cleanup.
Use Gap Findings for the full factor audit and Reset Queue for the working plan. If a row looks wrong, revisit the relevant answer choice or weight before exporting anything.
Check Sleep Friction Map, Reset Brief, and JSON when you need a visual comparison, a plain-language plan, or a structured record for the next pass.

Interpreting Results:

Total score is a 0 to 100 weighted friction score for the selected habit answers. It is not a sleep-quality score, a sleep-duration estimate, or a medical screen. A high score means the current answers contain more routine friction; a low score means the scored cues look relatively protected.

The Primary driver can matter more than the headline band. If one domain carries most of the drag, start with that domain and keep the first queue narrow. If several domains are similar, hold the same small queue for the full retest window before adding more changes.

Protected factors are anchors to keep steady while other changes are tested.
Watch factors are mild enough to monitor, especially if sleep worsens or the routine shifts.
Gap and Critical factors are the main candidates for the reset plan.
Reset Queue is capped by Focus queue size, so it may leave some imperfect habits out of the first experiment.

A heavy score does not prove habits are the only cause, and a light score does not prove habits are irrelevant. If the result clashes with symptoms, check whether the answers were too generous, compare the protected anchors with the reset brief, and consider a sleep diary or professional review.

Technical Details:

The checker treats each habit as a friction cue. Every cue has a selected answer with a raw severity from 0 to 3, a domain, an effort score, an expected impact window, and a leverage weight. The four domains are Substance timing, Circadian anchors, Arousal loop, and Bedroom load.

The total score is normalized, so domain weights change contribution without changing the maximum scale. Raising the arousal loop weight, for example, makes evening screens, clock checking, and wakeful bed use count more in the numerator, while the denominator rises too. Compare repeated runs only when answers, weights, queue size, reset pace, and retest window stay consistent.

Formula Core:

Each selected answer contributes a weighted factor. The total score converts the weighted load into a percentage of the maximum possible weighted load.

weightedFactor = rawScore \times domainWeight

totalScore = 100 \times \frac{\sum weightedFactor}{\sum 3 \times domainWeight}

With all ten factors at 1.00x weight, the maximum weighted load is 30. If the selected answers add up to 12.6 weighted points, the score is 100 x 12.6 / 30 = 42.0, which reaches Moderate drag.

Sleep hygiene scoring bands and boundaries
Output	Boundary	Meaning
Protected	`raw score < 0.6`	The selected answer is currently low friction.
Watch	`0.6 <= raw score < 1.6`	The cue is present enough to monitor.
Gap	`1.6 <= raw score < 2.6`	The cue is adding meaningful routine friction.
Critical	`raw score >= 2.6`	The cue is one of the strongest friction choices for that factor.
Low drag	`total score < 22`	The selected routine has relatively little weighted friction.
Building drag	`22 <= total score < 42`	Several cues may matter, but the pattern is not broadly loaded.
Moderate drag	`42 <= total score < 62`	A deliberate reset is worth testing.
Heavy drag	`total score >= 62`	The routine carries broad or intense friction across one or more domains.

Reset Queue Rules:

The reset queue starts with factors whose raw score is at least 1.0. It ranks them by weighted severity, built-in leverage, expected response speed, effort, reset pace, and a bonus for stronger gaps. The visible leverage label is Very high at 72 or above, High from 56 to below 72, Medium from 40 to below 56, and Low below 40.

Reset queue timing rules
Queue output	Rule	Practical meaning
Tonight	Early queue item and effort score 1 or 2	A low- or medium-effort change can start immediately.
Next 3 nights	Raw score at least 2.5, or one of the first two ranked items	The cue is severe enough or ranked high enough to test early.
This week	Expected impact window of 5 days or less after earlier rules	The change may respond within the current week.
Week 2	Remaining queued items	The change is slower or heavier, so it should not crowd the first nights.

The reset tempo is a separate guardrail. It starts from the total score, adds 8 points for each Critical factor and 2 points for each Gap, then labels the profile as Maintain anchors, Targeted reset, Focused reset, or Full reset. That label is a planning cue, not a diagnosis.

Limitations:

This is an informational sleep-habit audit. It does not diagnose insomnia, sleep apnea, circadian rhythm disorders, medication effects, mental health conditions, pain-related sleep disruption, or other clinical causes of poor sleep.

The score depends on self-reported habits and selected domain weights.
The checker does not include sleep duration, sleep efficiency, wake-after-sleep-onset time, wearable data, medication history, medical history, or a formal sleep diary.
Schedule, morning-light, and bed-association changes often need repeated days before they are fair to judge.
The habit answers are processed in the browser and can be copied or downloaded from the visible outputs when you choose.
Seek professional advice for persistent insomnia, severe daytime sleepiness, breathing pauses, loud snoring, unsafe drowsiness, or symptoms that do not improve after routine changes.

Advanced Tips:

Keep Focus queue size small when several gaps appear at once. A 2- or 3-item queue is easier to repeat than a broad reset plan.
Use Gentle bias when the first experiment should favor lower-effort changes. Use Focused bias when stronger gaps should outrank quick wins.
Raise a domain weight only when the question warrants it, such as testing arousal-heavy evenings or schedule drift. Record the same weights before comparing future runs.
Use the Sleep Friction Map to spot high weighted factors that did not make the capped queue, then revisit them after the current retest window.
Export the Reset Queue or Reset Brief before making changes so the next pass can compare the same plan against the new score.

Worked Examples:

Late stimulation with clock checks

A profile with Interactive or emotional screen time near bed, Repeated or compulsive checking, and Bed is a regular work or entertainment zone can make the arousal loop the primary driver even when schedule and room answers look protected. The queue is likely to favor moving wakeful activity out of bed, hiding the clock, and changing the last screen block before rebuilding the whole schedule.

Weekend drift with catch-up naps

Selecting Rotating or catch-up pattern most weeks, Frequent catch-up naps after poor nights, and Some days for morning light pushes the circadian anchor domain upward. A focused reset should usually protect one wake time, add morning light, and keep naps early or short through the chosen retest window.

Low drag but ongoing symptoms

A profile with early caffeine, rare bedtime alcohol, a dark and cool room, rare clock checking, sleep-only bed use, and daily morning light may return Low drag. If sleep is still poor, the result should not be treated as proof that habits are irrelevant. Check whether the answers were too optimistic, protect the anchors, and look beyond sleep hygiene with a diary or clinician-supported review.

Weight change moves the band

If the same answers move from Building drag to Moderate drag after the arousal loop weight is raised, the habit answers did not change. The score changed because screens, clock checking, and wakeful bed use were made more influential for that pass.

FAQ:

Does Heavy drag mean I have insomnia?

No. Heavy drag means the selected sleep-hygiene answers produced a high weighted friction score. Insomnia is a clinical condition and needs a broader assessment than this habit checklist.

Why did the Reset Queue leave out a gap?

The queue includes only factors with raw score at least 1.0 and is capped by Focus queue size. Some lower-priority gaps may wait so the first experiment stays repeatable.

Should I use a preset or Custom?

Use a preset when you want a fast starting profile, then edit every answer that does not match your real routine. Use Custom when you already know the pattern and want the least guided pass.

Why did changing a weight move the primary driver?

Weights multiply the raw scores in their domain. Raising the arousal loop weight makes evening screens, clock checking, and wakeful bed use count more in the total and queue ranking.

How long should I wait before checking again?

Use the selected Retest window. Quick changes such as hiding the clock may show up sooner, while schedule, light, and bed-association changes usually need repeated days.

What if the score looks too low for how I feel?

Recheck the answers for generous choices, especially schedule consistency, naps, screens, clock checking, and bed use. If the answers still look accurate, the problem may sit outside sleep hygiene and deserves a diary or professional review.
