Cognitive behavioral therapy for insomnia (CBT-I) is a structured, evidence-based treatment for persistent difficulty falling asleep, staying asleep, or returning to sleep. It addresses the learned behaviors, distressing expectations, and physiological and cognitive arousal that can keep insomnia going after its original trigger has passed. Multicomponent CBT-I is recommended as a first-line treatment for adults with chronic insomnia disorder by the American Academy of Sleep Medicine (AASM), the American College of Physicians, and the 2025 VA/DoD clinical practice guideline.
CBT-I is a treatment process rather than a single bedtime tip. A clinician assesses sleep and daytime function, develops a working explanation of what maintains the insomnia, and combines behavioral and cognitive methods with a carefully monitored sleep schedule. The treatment has specific components, measurable goals, legitimate short-term challenges, and circumstances that require adaptations. This guide explains what the research supports, how a typical course unfolds, and how people can obtain appropriately matched care.
For a broader clinical discussion of insomnia and its management, see Insomnia: Symptoms, Causes, Diagnosis, and Treatment.
What is CBT-I?
CBT-I means cognitive behavioral therapy specifically adapted to insomnia. Its cognitive component works with worry, catastrophic predictions, rigid expectations, and excessive monitoring of sleep. Its behavioral component changes patterns such as staying in bed awake for long periods, irregular rising times, and compensatory extensions of time in bed that can weaken the relationship between bed and sleep. Education explains the roles of sleep pressure and circadian timing; relaxation techniques may be added when appropriate.
The goal is more reliable, restorative sleep and better daytime functioning. Clinicians often monitor how long it takes someone to fall asleep, how long they remain awake after initially sleeping, how much time they spend asleep relative to time in bed, how distressed they feel about sleep, and how insomnia affects daily life. Total sleep time matters, but it is only one outcome. An improvement in sleep continuity and confidence may precede a large increase in hours slept. The AASM systematic review evaluates these outcomes separately.
CBT-I is usually delivered individually, in a group, by telehealth, or through a structured digital program. A typical therapist-guided course involves several meetings across approximately six to eight weeks, although some validated brief protocols are shorter and complex situations need more time. The NIH National Heart, Lung, and Blood Institute (NHLBI) describes CBT-I as a six- to eight-week treatment framework.
Who is CBT-I for?
The clearest evidence applies to adults with chronic insomnia disorder. Persistent insomnia involves difficulty initiating or maintaining sleep or early awakening despite adequate opportunity and circumstances for sleep, together with daytime consequences. A commonly used chronicity threshold is symptoms on at least three nights a week for at least three months, alongside clinical criteria. A person who sleeps too little because of work schedules, caregiving responsibilities, or another external restriction may have insufficient sleep opportunity rather than an insomnia disorder. Someone whose preferred sleep period falls unusually late may require assessment for circadian rhythm misalignment. The NHLBI diagnostic guidance and the AASM ICSD-3-TR classification overview clarify these distinctions.
CBT-I can help people whose insomnia coexists with depression, anxiety, posttraumatic stress disorder, chronic pain, cancer-related symptoms, or other conditions, provided clinicians address relevant risks and concurrent causes. Insomnia may deserve its own treatment even when another diagnosis is present. A meta-analysis of insomnia comorbid with psychiatric and medical conditions found meaningful improvements in sleep outcomes; it does not establish that insomnia treatment alone resolves every coexisting disorder.
An isolated bad night, a brief period of understandable sleep disruption, or daytime tiredness without a clear insomnia complaint does not automatically call for a full CBT-I course. A clinician establishes which sleep problem is being treated and whether time, supportive care, addressing a precipitating stressor, circadian treatment, or further medical assessment is more suitable.
Why insomnia can persist: the mechanisms CBT-I addresses
Predisposing, precipitating, and perpetuating factors
An influential clinical account describes how baseline vulnerability interacts with a triggering event and subsequent maintaining habits. Stress, illness, pain, a disrupted routine, or an emotionally demanding period may initiate sleep problems. In response, someone may begin going to bed much earlier, remaining in bed after waking, sleeping in on difficult mornings, taking prolonged naps, watching the clock, or trying harder to force sleep. Each response may make immediate intuitive sense, yet some can perpetuate fragmented sleep or anticipatory anxiety.
This framework helps organize treatment, but it is not a test that proves the cause of an individual's insomnia. Biological factors, medication effects, environmental constraints, life stage, and other sleep disorders can contribute. CBT-I targets changeable maintaining processes within this larger picture.
Hyperarousal and conditioned wakefulness
Many patients describe feeling exhausted throughout the day but strikingly alert when they get into bed. Their attention turns toward whether sleep will occur, tomorrow's responsibilities, bodily sensations, the clock, and the consequences of another poor night. Bedtime itself can become a cue for effortful monitoring. Hyperarousal is a research and clinical framework involving cognitive, emotional, and physiological activation; it is not a standalone home diagnosis. The relationship between self-reported alertness, physiological measures, and objective sleep varies across individuals.
Stimulus control targets learned associations between the sleeping environment and wakeful struggle. Cognitive interventions address escalating predictions and safety behaviors. Sleep scheduling aims to consolidate sleep while respecting individual medical safety. Together these methods can interrupt a reinforcing loop between sleep difficulty and the fear of sleep difficulty.
Sleep pressure, circadian timing, and time in bed
Sleep is regulated partly by a homeostatic drive that builds with time awake and a circadian timing system that helps organize periods of alertness and sleep propensity. Irregular schedules, long naps, and extended time in bed may interfere with a stable pattern for some people with insomnia. CBT-I uses predictable wake times and carefully adjusted sleep opportunities to improve consolidation. These changes must reflect the patient's life, sleep need, alertness, medical conditions, and occupational responsibilities.
Chronotype, shift work, delayed sleep-wake phase disorder, and insufficient sleep are related but different phenomena. If the underlying problem involves circadian timing, ordinary CBT-I alone may not address the timing disorder. Light exposure, melatonin, and schedule shifts require diagnosis-specific planning, particularly with bipolar disorder or other relevant vulnerabilities.
The core components of CBT-I
1. Assessment, education, and shared treatment goals
A clinician first takes a sleep history and reviews timing, patterns, duration, daytime symptoms, sleep opportunity, medication and substance use, physical and mental health, and functional or safety concerns. A sleep diary, often spanning one or two weeks, records usual bedtimes, attempted sleep, awakenings, rising times, and naps. Diaries provide estimates; their numbers are not equivalent to laboratory-measured sleep. The NHLBI recommends a sleep diary as a useful part of assessment.
The therapist explains the treatment rationale and agrees on meaningful outcomes: less insomnia-related distress, improved ability to sleep at appropriate times, improved functioning, and sustainable patterns. A plan should account for pain, caregiving, shift work, disability, neurodivergent needs, and the person's capacity to follow behavioral instructions. Clinical collaboration and adaptation are central to a safe program.
2. Stimulus control
Stimulus control is intended to rebuild a strong connection between bed and sleep rather than prolonged wakefulness, frustration, work, or monitoring. A therapist typically helps the patient keep a consistent rising time, approach bedtime when sleepy, reserve the bed chiefly for sleep and sex when appropriate, and respond flexibly to prolonged wakefulness by leaving the sleeping environment for a quiet activity until sleepiness returns.
The treatment is guided by actual experience rather than a stopwatch. Repeatedly timing awakenings, monitoring a wearable, or getting up at a fixed number of minutes can become another source of pressure. The mobility, fall risk, housing circumstances, caregiving duties, and safety of getting out of bed at night must be considered. Some patients benefit from an adapted version of the instruction.
The AASM behavioral-treatment guideline supports stimulus control as a possible single-component treatment with a conditional recommendation. In standard CBT-I it commonly works together with other components and ongoing review.
3. Sleep restriction therapy and sleep compression
Sleep restriction therapy, sometimes called sleep scheduling or sleep-window therapy, aligns the time allotted for sleep more closely with estimated time actually slept and then cautiously adjusts that opportunity as sleep becomes more consolidated. The clinical intention is to reduce prolonged periods of frustrated wakefulness in bed and rebuild predictable sleep. Sleep compression is a gentler variant that reduces excessive time in bed more gradually and may suit certain patients.
The word restriction is easy to misunderstand. Treatment is not a general recommendation to deprive yourself of sleep or to aim for the shortest possible night. A specialist uses sleep records, symptom response, medical history, daytime safety, and an individualized minimum sleep opportunity. Changes are reviewed over the course of treatment. Early increases in sleepiness are possible, and unsafe applications can impair concentration, driving, or work performance.
Sleep-window intervention needs particular caution when there is a history of mania or hypomania, seizures, severe daytime sleepiness, high fall risk, safety-sensitive work, or another condition that can deteriorate with acute sleep loss. Untreated sleep apnea, unstable medical illness, and complex medication regimens also call for evaluation and coordinated care. People should not copy an aggressive sleep-window formula from the internet and apply it without assessment. The 2025 VA/DoD guideline places behavioral insomnia treatment within a broader clinical screening and safety pathway.
4. Cognitive therapy for sleep-related beliefs and worry
Many people with long-standing insomnia develop understandable but unhelpful conclusions, such as the belief that one imperfect night will make every task impossible, or that sleep must be controlled through ever more elaborate rituals. Cognitive therapy explores the evidence for these expectations, identifies all-or-nothing interpretations, and develops a more flexible relationship with inevitable night-to-night variation.
Methods may include identifying bedtime predictions, examining how they change behavior, testing beliefs about control and daytime functioning, and modifying catastrophic judgments. Therapists can also address clock checking, reassurance seeking, pressure to achieve a perfect sleep score, and constant planning for the next night. This is a collaborative examination of patterns; it does not ask patients to deny genuine fatigue or serious consequences of insufficient sleep.
A 2024 component network meta-analysis spanning 241 trials identified cognitive restructuring, sleep restriction, and stimulus control among components associated with stronger remission outcomes. Component findings estimate contributions within heterogeneous treatment packages and do not provide a universal ranking for individual patients.
5. Sleep education and sleep hygiene
Sleep education covers the biological regulation of sleep, realistic variation in sleep need, the effects of caffeine and alcohol, daytime activity, morning light, bedroom conditions, and why regularity can help. Good sleep habits support treatment and sometimes remove an obvious source of disturbance. For example, late-day caffeine or an inconsistent schedule may deserve attention in an individualized care plan.
However, sleep hygiene advice alone is a substantially narrower intervention than multicomponent CBT-I. A person with chronic conditioned wakefulness and entrenched sleep anxiety may follow every routine suggestion and still experience disabling insomnia. The AASM specifically suggests against sleep hygiene as a single-component treatment for adult chronic insomnia disorder. Sleep hygiene is an adjunct that should be fitted to the case, not offered as a complete substitute for evidence-based therapy.
6. Relaxation and reduction of sleep-related effort
Depending on the patient, treatment may include progressive muscle relaxation, paced breathing, guided imagery, or methods that reduce mental and physical tension. Relaxation is useful when it lowers activation or helps someone approach bedtime less anxiously. It becomes counterproductive if treated as a mandatory performance test in which relaxation must produce immediate sleep.
CBT-I also helps patients make room for ordinary fluctuations in alertness. Acceptance-oriented or mindfulness-related techniques sometimes appear in adapted protocols. Their conceptual usefulness should be distinguished from the strength of evidence for the full multicomponent CBT-I package. Relaxation as a standalone treatment receives a conditional, rather than strong, AASM recommendation.
What happens during a typical course of treatment?
Initial assessment and baseline
At the beginning, the clinician clarifies whether the presenting complaint meets criteria for chronic insomnia disorder, explores other sleep and medical explanations, and checks whether it is safe to use standard behavioral methods. Patients may complete a sleep diary, describe the timing and meaning of their sleeplessness, and identify objectives relevant to their daily lives. Validated measures such as the Insomnia Severity Index can track symptom change; a questionnaire score cannot establish the diagnosis on its own.
Early treatment sessions
The therapist explains why habits and anticipatory responses can maintain insomnia, builds a workable wake-time and bedtime strategy, and introduces suitable behavioral components. Cognitive patterns and beliefs about sleep are identified without blame. Someone whose schedule is constrained by caregiving, disability, or night shifts may need a different plan from someone with a stable daytime routine.
Early treatment sometimes feels demanding. Time spent awake in bed may fall before total sleep increases. A temporary rise in daytime sleepiness, frustration with scheduling, or concern about changing familiar coping habits should be discussed promptly with the treating clinician. Patients who drive, operate equipment, or have safety-critical responsibilities need clear precautions.
Monitoring, adjustment, and relapse prevention
At subsequent visits, the clinician reviews diary trends, daytime alertness, distress, adherence, practical barriers, and potential adverse effects. The sleep window is adjusted when clinically appropriate, rather than kept fixed regardless of response. Cognitive work continues as expectations and behaviors change. The final phase develops a plan for travel, illness, stressful periods, isolated poor nights, and return of symptoms.
A successful course leaves people with skills they can use when insomnia recurs. Lasting remission is possible, but relapse or incomplete response can occur. A return of insomnia warrants reassessment, especially if new snoring, unusual movements, mood symptoms, medications, pain, or daytime sleepiness has developed.
Does CBT-I work? What clinical trials and guidelines show
The evidence base for multicomponent CBT-I includes randomized controlled trials, systematic reviews, component analyses, and professional guidelines. The AASM makes a strong recommendation for multicomponent CBT-I in chronic insomnia disorder in adults, while its recommendation for each of several isolated components is conditional. The strength of this distinction matters: the full treatment has a more comprehensive evidence base than generic sleep tips.
A 2015 meta-analysis by Trauer and colleagues, drawing on 20 randomized trials and 1,162 adults with chronic insomnia, found clinically meaningful improvements in diary-based sleep onset latency, time awake after sleep onset, and sleep efficiency. These are averages across trial populations; an individual response will depend on the baseline problem, other conditions, access, and implementation. The 2021 AASM systematic review and GRADE assessment provides a broader synthesis underpinning the behavioral guideline.
The evidence does not mean every participant becomes a consistently long sleeper, or that one intervention fixes every form of fatigue. Sleep outcomes in trials are often self-reported, and a reduction in insomnia severity or wakefulness can occur with little immediate change in objectively measured total sleep time. This distinction between the person's experience and device-based indicators helps interpret outcomes responsibly.
For people with psychiatric or medical comorbidity, Wu and colleagues' meta-analysis supports treating insomnia directly. However, improvement in associated depression, pain, or anxiety may be smaller or less consistent than improvement in sleep. Clinical trials typically impose enrollment rules and may underrepresent people with severe instability or complex safety risks. Generalizing results to every clinical population requires judgment.
A major 2024 component network meta-analysis synthesized 241 trials involving more than 31,000 participants. It supports the importance of specific cognitive and behavioral ingredients while also highlighting differences in delivery and study design. This literature strengthens confidence in CBT-I as a treatment class and leaves room for refinement of individual treatment components.
CBT-I versus sleeping pills: what the 2026 guidance changes
CBT-I and insomnia medications have different roles. Medications may alter sleep-promoting or wake-promoting signaling and can have benefits and harms that depend on the product and patient. CBT-I teaches strategies aimed at changing maintaining mechanisms and building skills that persist beyond a particular course. A clinician may consider medications when symptoms are severe, when CBT-I is unavailable, or when a carefully assessed treatment plan calls for them. Medication choice and discontinuation require individualized medical decisions.
The 2026 AASM guideline on combination treatment adds an important refinement. It conditionally favors starting CBT-I together with an insomnia medication over medication alone, but conditionally advises against routine combination over CBT-I alone. Both comparisons rested on low-certainty evidence. Its authors note that patients who especially value an early increase in total sleep time may reasonably prefer combination treatment after shared decision-making.
These recommendations do not imply that a person should stop prescribed sleeping medication at the beginning of CBT-I. Abruptly changing sedative-hypnotics, benzodiazepines, or other medications can cause withdrawal or other complications. The prescribing clinician should coordinate any tapering or medication changes. A treatment that is initially combined can be reassessed as sleep and daytime function evolve.
Digital CBT-I, online programs, and telehealth
CBT-I can be delivered in person, by telehealth, in groups, or through structured digital treatment. Digital CBT-I is a program that implements CBT-I methods with an organized sequence and monitoring. Its evidence should not be transferred automatically to an ordinary relaxation app, a sleep tracker, a generic chatbot, or an AI companion that discusses sleep.
A 2025 systematic review of fully automated digital CBT-I included 29 randomized trials and 9,475 participants. Automated programs improved insomnia severity compared with control conditions, while comparisons suggested that therapist-supported delivery may provide additional benefit. A 2025 meta-analysis of remission and treatment response across CBT-I delivery methods shows why engagement and clinically meaningful outcomes matter in addition to accessibility.
Digital access can be especially valuable where trained clinicians are scarce or travel is difficult. Yet program content, screening, human oversight, privacy practices, dropout rates, patient accessibility, and instructions for escalating safety concerns vary. Patients with significant bipolar-spectrum risk, seizures, marked daytime sleepiness, untreated breathing problems, or complex medical comorbidity should not rely on fully automated sleep-window changes without clinical review. Insurance coverage, regulatory status, and local availability should be checked for the specific program rather than presumed from the phrase digital CBT-I.
When CBT-I needs adaptation or a different first step
Sleep apnea, restless legs, parasomnias, and hypersomnolence
Loud habitual snoring, witnessed breathing pauses, gasping, significant unexplained daytime sleepiness, or drowsy driving call for assessment of obstructive sleep apnea or other medical sleep conditions. Uncomfortable urges to move the legs at rest may point toward restless legs syndrome. Dream enactment with injury risk, unusual nocturnal behaviors, and sudden sleep episodes need appropriate evaluation. CBT-I may be useful when insomnia coexists with a diagnosed condition, but it cannot replace treatment of the other disorder.
A sleep study is not routinely needed to establish uncomplicated insomnia. Clinicians use history and examination to decide whether polysomnography, a home sleep apnea test, or another investigation addresses a credible differential diagnosis. Consumer wearables can help notice patterns but cannot rule out sleep apnea or establish precise sleep stages, nor should they become a nightly source of compulsive reassurance.
Bipolar disorder, seizures, high-risk work, and severe daytime impairment
A history of mania or hypomania warrants special caution with strategies that acutely reduce time in bed, because sleep loss can destabilize mood. A seizure disorder or safety-sensitive employment similarly calls for tailored planning. People with high fall risk, limited nighttime mobility, and substantial daytime impairment may need adapted stimulus control or gradual compression. Patients should disclose these risks before sleep scheduling begins.
An abrupt reduction in need for sleep accompanied by unusual energy, racing thoughts, elevated or irritable mood, impulsivity, or disorganized behavior needs timely clinical assessment rather than routine insomnia self-treatment. Severe sleepiness while driving or operating machinery is an immediate safety concern. These situations can coexist with insomnia complaints but change the order of care.
Depression, trauma, chronic pain, and pregnancy
Mental health symptoms and insomnia often reinforce one another. When someone has depression, PTSD, or chronic pain, treatment can coordinate insomnia-specific work with care for the other condition. Sleep-window decisions may need modification for severe pain, fatigue, trauma-related hypervigilance, or functional limits. During pregnancy or the postpartum period, nighttime care duties and changing physical needs affect sleep opportunity and safety; treatment should be adapted with the relevant clinician.
CBT-I is a framework that permits individualization. Protocol flexibility is a clinical feature, not a failure to follow the program. The key question is which maintaining factors are present, what interventions have evidence for this patient, and which risks require a modified sequence.
What CBT-I can and cannot promise
CBT-I has a strong evidence base for chronic insomnia in adults and can provide durable strategies for coping with later sleep disruption. It commonly reduces insomnia severity and improves perceived sleep continuity and confidence. The response is not instantaneous, and improvement may develop over several weeks. Some people need additional sessions, further investigation, or a combination of treatments.
CBT-I does not create unlimited sleep opportunity, remove a person's caregiving or work constraints, reverse sleep apnea, normalize a circadian phase disorder without targeted treatment, or guarantee complete remission. It also does not make fatigue caused by anemia, inflammatory illness, medications, depression, or another medical condition disappear simply because nights become more consolidated. Clinical reassessment is indicated when outcomes do not match the working explanation.
How to find qualified CBT-I treatment
An appropriate first contact can be a primary care clinician, behavioral sleep medicine specialist, sleep physician, or mental health professional trained in CBT-I. Ask whether the provider delivers a structured multicomponent program, uses a baseline sleep diary, monitors insomnia severity and daytime safety, adjusts plans for comorbidities, and coordinates care with prescribers or other specialists. The relevant training and experience are more informative than a broad advertisement promising better sleep.
A patient may ask: How do you assess conditions that resemble insomnia? What treatment components do you use and why? How will you respond if I become excessively sleepy or show mood symptoms? What kinds of monitoring do you use? Are sessions available remotely? How is my health information protected? How do you decide whether to refer for sleep testing? What happens if this treatment does not work for me?
When access is limited, a validated digital CBT-I program may be an alternative for appropriately screened patients. Group therapy, telehealth, primary-care integrated behavioral treatment, or a brief behavioral approach may also be available. The most useful option is one that fits the clinical presentation and can be completed safely.
Practical expectations during treatment
Before starting, it is helpful to separate your goals into sleep outcomes and daytime outcomes. For example, improvement may mean less time worrying about sleep, more predictable mornings, fewer extended awakenings, better concentration, and the ability to resume valued activities. Such outcomes remain meaningful even when nightly sleep duration fluctuates.
Keep a simple, honest record rather than striving for perfect measurements. When a night's sleep is difficult, the point of monitoring is to help the clinician understand patterns, not to grade personal performance. Avoid using device-based scores as proof that an entire day will go badly. Discuss emerging adverse effects, unusual sleepiness, mood changes, or barriers with your provider. A treatment protocol can be adjusted when real-life conditions change.
Frequently asked questions
Is CBT-I the same thing as regular CBT?
CBT-I uses cognitive and behavioral principles shared with broader cognitive behavioral therapy, but it focuses on sleep-specific maintaining mechanisms and includes interventions such as stimulus control and supervised sleep-window adjustment. A therapist trained in general CBT may have useful skills yet need additional behavioral sleep medicine training to deliver the full protocol safely.
Does CBT-I work without medication?
Yes, many people improve with CBT-I as a standalone treatment, and major clinical guidelines recommend it as an initial treatment for adult chronic insomnia. Some patients need additional medical or psychological treatment, and medication decisions should be shared with the relevant prescriber. The 2026 AASM comparison guideline does not support adding insomnia medication routinely when CBT-I alone is suitable.
How long does it take to see results?
A typical course lasts around six to eight weeks, though timing varies. Some people notice changes early in sleep continuity or confidence, while others require more time and adaptations. Early sleepiness during a monitored sleep-scheduling phase is not a reliable marker that treatment is succeeding; safety and overall functioning should be assessed throughout.
Can I do CBT-I on my own?
Self-guided resources can teach sleep principles, and structured digital CBT-I can be effective for suitable patients. However, the core scheduling component can cause short-term sleepiness and may be inappropriate without supervision when specific medical, psychiatric, or safety risks are present. A generic list of bedtime instructions is not equivalent to an assessed and monitored treatment program.
Is sleep restriction therapy safe for everyone?
No. Sleep-window manipulation must be individualized. Patients with bipolar-spectrum vulnerability, seizures, excessive daytime sleepiness, fall risks, occupational driving demands, or unstable medical conditions require particular caution and may need another approach or more clinical oversight. A fixed formula applied without screening is not appropriate.
What if I have both insomnia and sleep apnea?
Both conditions may require treatment. CBT-I can address insomnia symptoms, while an obstructive breathing disorder requires its own assessment and treatment plan. The 2025 VA/DoD clinical guideline addresses evaluation and management of both problems. Sleep medication or behavioral scheduling decisions should be coordinated when the diagnoses coexist.
Can CBT-I help sleep anxiety?
Sleep-related worry, clock watching, and conditioned arousal are common CBT-I targets. Therapists work on distressing beliefs and unhelpful checking or compensatory behaviors while improving sleep regularity. Broader anxiety disorders or traumatic symptoms may also need dedicated care.
What if I sleep only a few hours but my tracker says my sleep efficiency is high?
Device estimates and diary measures have different limitations. A high sleep-efficiency estimate does not establish adequate sleep duration, well-being, or absence of another disorder. Treatment decisions should reflect the full history, actual sleep opportunity, daytime function, clinical assessment, and safety rather than one app score.
Will insomnia come back after CBT-I?
Some people maintain substantial benefits, while others have recurrent periods of poor sleep during stress, illness, travel, or changing schedules. Relapse-prevention work helps people recognize patterns and seek timely support without restarting an unsafe sleep-window regimen by themselves.
When should I seek medical help urgently?
Seek prompt evaluation for severe daytime sleepiness with driving risk, breathing pauses with significant symptoms, violent dream enactment or injuries, a marked change in sleep associated with manic symptoms, or significant deterioration in mental or physical health. Urgent local care is appropriate when immediate safety is threatened. A routine online sleep program should not delay assessment.
