Research — Insight Sessions for the Focus & Sleep Gaps¶

Fills the Part-4 gap analysis in ../insight-session-mapping.md. The two most under-served Library categories are focus (only 2 source articles: Concentration, At Work) and sleep (4 articles that explain why sleep is hard but not how to fix it). This doc proposes net-new insight sessions for the gap topics named in Part 4 that no existing article or backlog row already covers.

Scope & dedup¶

These slugs already exist and are not re-proposed here:

focus: concentrating-with-tinnitus, working-with-tinnitus, the-attention-amplification-loop
sleep: why-tinnitus-is-louder-at-night, sleep-and-tinnitus-the-bidirectional-spiral
adjacent: the-checking-compulsion-explained, sound-therapy-what-it-does-and-doesnt-do

The proposals below take a distinct angle from each of those (e.g. the checking item here is about app/digital monitoring specifically, not the general compulsion already covered).

A note on grounding¶

The insight authoring standard (../authoring/standards/session-insight.md) says article-derived insights ground in their source article. These gap topics have no source article — they are the gaps. So the sessions below ground directly in the clinical literature cited here, exactly as the standard permits for technique-derived content. Every claim below traces to a real source I verified; where a claim is general clinical consensus without a single anchor study, it is marked [consensus], not attributed to a specific paper. No citation is fabricated.

FOCUS¶

1. Attention training — building the switch¶

slug: attention-training-for-tinnitus · approach: CBT

Key evidence points: - The cognitive signature of bothersome chronic tinnitus is a failure to switch attention away from the sound — impaired top-down control keeps the signal in awareness, rather than the sound being objectively loud (Roberts et al. / Trevis et al., Front Psychol 2016, PMC4996052). - Attention is trainable: the relevant skill is not "block the sound out" but "move attention onto a task and back at will." Clinically this is framed as directed attention — using an engaging external focus to pull attention off the tinnitus — and is one of the two pillars (with habituation) of behavioural tinnitus management (Searchfield et al., Am J Audiol 2023, AJA-22-00178). - Multisensory / auditory attention-training protocols produce small but statistically significant reductions in tinnitus severity and measurable gains in attentional control (Spiegel et al., Sci Rep 2015, srep10802; perceptual-training RCT, PMID 26910854).

2. Digital tool hygiene — using a tinnitus app without feeding the loop¶

slug: using-a-tinnitus-app-without-checking · approach: CBT

Key evidence points: - In the cognitive-behavioural model, distress is maintained not by the sound's physical properties but by attention, monitoring, and safety behaviours — including the reassurance-seeking habit of repeatedly checking "is it louder today?" (UCSF EARS tinnitus programme; cognitive-behavioural model of tinnitus distress). - The corrective move is attentional flexibility, not more measuring: reduce the frequency of "is it louder?" checks and let attention rest elsewhere (UCSF EARS, tinnitus management strategies). - Particularly load-bearing for Naluma, which is itself an app: a tool meant to help can become a monitoring ritual that keeps tinnitus in the brain's threat-detection loop. [consensus / Naluma-specific framing]

3. Tinnitus at school / studying¶

slug: studying-with-tinnitus · approach: CBT

Key evidence points: - Concentration difficulty is one of the most commonly reported functional impacts: in surveyed populations roughly 41% report mild, 33% moderate, and 20% severe trouble concentrating (Hearing Health Foundation, Working With Tinnitus). - The same workplace levers apply to study settings: a low, neutral background sound beats silence, and interesting-enough audio holds attention on the task rather than the tinnitus (NHS audiology sound-enrichment guidance; Searchfield 2023 "interesting sound" for directed attention). - Short timed work intervals (e.g. Pomodoro-style 25-minute blocks) reduce the cost of attention slipping to the tinnitus and make sustained focus more achievable. [consensus — Pomodoro is a general attention technique, not tinnitus-specific]

SLEEP¶

4. Sleep hygiene built for tinnitus¶

slug: sleep-hygiene-for-tinnitus · approach: CBT-I

Key evidence points: - The shift from a noisy daytime environment to a quiet bedroom makes tinnitus more noticeable at lights-out; low-level neutral sound in the bedroom reduces that contrast (NHS audiology — Newcastle Hospitals & NHS Forth Valley tinnitus sound-enrichment guidance). - Standard sleep-hygiene levers — reduce caffeine and alcohol, avoid stimulating activity and exercise close to bed — apply and matter for tinnitus sufferers (NHS audiology guidance). - Keep the bedroom sound quiet, not attention-grabbing: a fan, rain, or waves help; talk radio or anything that pulls attention works against falling asleep (NHS Forth Valley).

5. CBT-I — the evidence-based fix for tinnitus insomnia¶

slug: cbt-i-for-tinnitus-insomnia · approach: CBT-I

Key evidence points: - In a 3-arm RCT (n=102), CBT-I was superior to audiology-based care and a sleep support group at reducing insomnia and improving sleep efficiency, with gains held at 6-month follow-up — and it also reduced tinnitus distress (Marks, Hallsworth, Vogt, Klein & McKenna, Cogn Behav Ther 2023, PMID 35762946). - Clinically meaningful improvement was reported by >80% in CBT-I vs ~47% in audiology-based care vs ~20% in the sleep support group (Marks et al. 2023). - CBT-I's active ingredients are behavioural, not hygiene tips: stimulus control (bed = sleep only; leave the bed if awake ~20 min) and sleep restriction / sleep-efficiency work (Sleep Foundation CBT-I overview; Rossman, CBT-I: A Primer, PMC10002474). These are what drive the effect.

6. The sleep–tinnitus loop you can actually break¶

slug: breaking-the-sleep-tinnitus-loop · approach: CBT-I

Distinct from existing sleep-and-tinnitus-the-bidirectional-spiral (mechanism explainer): this one is action-first — what to do tonight when you're lying awake.

Key evidence points: - Poor sleep amplifies next-day tinnitus reactivity, and louder/worse tinnitus then disrupts sleep — a self-reinforcing loop where sleep loss is a major driver of perceived severity (Naluma evidence base, vault #342/#405; loop framing consistent with Marks et al. 2023 finding that fixing sleep lowers tinnitus distress). - The single highest-leverage rule: don't lie in bed awake fighting it. If you can't sleep within ~20 minutes, get up, do something quiet and low-stimulus in dim light, return when drowsy (stimulus control — NHS audiology; Sleep Foundation CBT-I). - One bad night is not a relapse: spikes track stress and sleep loss and are transient — treating a rough night as neutral data, not catastrophe, keeps the loop from tightening. [consensus — spike/sleep relationship; see Naluma evidence base]

7. Sound for sleep — set it below the ringing¶

slug: sound-therapy-for-sleep · approach: TRT

Distinct from existing sound-therapy-what-it-does-and-doesnt-do (general what-it-is): this one is the bedtime how-to — level, source, dependency.

Key evidence points: - Set bedside sound just below the level of your tinnitus so you can still faintly hear it ("partial masking") — this supports the brain reclassifying the signal as background; loud masking that drowns it out does not build habituation and tinnitus can rebound louder when the sound stops (NHS Forth Valley; AIHHP nighttime relief guidance; British Tinnitus Association sound enrichment principle). - Pick neutral, non-attention-grabbing sound (fan, rain, waves) over anything with words or melody hooks; the goal is to fill silence, not entertain (NHS audiology guidance). - It's a scaffold, not a crutch: many people stop needing bedside sound once a regular sleep pattern is re-established, and chasing ever-louder sound is a warning sign, not progress (NHS / AIHHP). [consensus]
