“Sleep hygiene” is the standard advice for insomnia — and for mild, situational sleep problems, it often suffices. But for chronic insomnia disorder, sleep hygiene alone isn’t enough. Patients have usually tried all the obvious things and still aren’t sleeping. They need real clinical intervention.
According to the American Academy of Sleep Medicine, chronic insomnia affects roughly 10% of adults — making it one of the most common health complaints in clinical practice. Evidence-based treatment exists. Most patients don’t access it.
What Chronic Insomnia Actually Is
DSM-5-TR insomnia disorder requires:
- Difficulty initiating sleep, maintaining sleep, or early morning awakening with inability to return to sleep
- Daytime distress or impairment
- Symptoms 3+ nights per week
- Persisting 3+ months
- Not better explained by another sleep disorder or substance
Why Sleep Hygiene Alone Often Fails
Standard sleep hygiene advice — consistent schedule, dark room, no screens, no caffeine after noon, no daytime naps — addresses environmental factors. But chronic insomnia involves more than environment:
Conditioned arousal
The bed itself becomes associated with wakefulness. Patients learn that bed = lying awake. The brain activates rather than settles when going to bed.
Cognitive arousal
Worry about sleep produces racing thoughts. Catastrophizing about consequences of not sleeping (“I’ll be useless tomorrow”) activates the nervous system at the worst possible time.
Sleep effort paradox
Trying to sleep produces wakefulness. Effortful relaxation is an oxymoron — the harder you try, the more activated you become.
Time misperception
Insomnia patients often spend 9 hours in bed to get 6 hours of sleep — drilling in the bed-wakefulness association.
Sleep hygiene doesn’t address these factors. Specific evidence-based interventions do.
Cognitive Behavioral Therapy for Insomnia (CBT-I)
The gold-standard treatment for chronic insomnia — more effective than sleep medications long-term and with no medication side effects. Components include:
Sleep restriction
Counterintuitively, reducing time in bed often increases sleep efficiency. By temporarily restricting bed time to actual sleep time, the brain re-establishes bed-sleep associations.
Stimulus control
Bed only for sleep (and sex). Getting up when can’t sleep. Returning only when sleepy. Re-conditions the brain’s bed-sleep association.
Cognitive restructuring
Addressing catastrophic beliefs about sleep loss. Patients often substantially overestimate the consequences of poor sleep.
Relaxation training
Specific techniques — progressive muscle relaxation, guided imagery, breathing exercises — for managing arousal.
Sleep hygiene
Important supporting element but not sufficient alone.
Medication Considerations
When CBT-I isn’t accessible or sufficient, medications can help — but with careful consideration:
Generally preferred
- Trazodone — low doses (25-100 mg), generally well-tolerated, no dependence risk
- Mirtazapine — sleep and appetite effects useful when depression coexists
- Doxepin (low dose) — FDA-approved for sleep maintenance at very low doses
- Melatonin — modest effect for some patients, especially circadian rhythm issues
Generally avoided long-term
- Benzodiazepines — tolerance, dependence, cognitive effects
- “Z-drugs” (zolpidem, eszopiclone) — similar issues, complex sleep behaviors
- Diphenhydramine (Benadryl, Tylenol PM) — anticholinergic effects, cognitive effects in older adults
Sometimes useful
- Suvorexant, lemborexant (DORAs) — newer mechanism, less dependence risk
- Short-term hypnotics for acute crises with clear plan to discontinue

Hypnotic accumulation
Patients often end up on sleep medications long-term, with tolerance and dependence — when CBT-I would have produced better, drug-free outcomes.
CBT-I plus careful medication
Dr. Farkas coordinates with CBT-I therapists when appropriate, uses safer medication options when needed, and supports patients off long-term hypnotics.
Sustainable sleep
Patients who address chronic insomnia properly often see lasting improvement without dependence on sleep medications.
Common Questions About Chronic Insomnia
Will CBT-I work if I’ve had insomnia for years?
Yes — duration of insomnia doesn’t significantly predict CBT-I response. Long-standing chronic insomnia responds well to evidence-based treatment.
Should I be tested for sleep apnea?
Often yes — particularly if you have snoring, witnessed apneas, daytime sleepiness, or risk factors (weight, age, neck size). Sleep apnea masquerading as insomnia is common.
Is melatonin safe long-term?
Generally yes at typical doses (0.5-5 mg). Most useful for circadian rhythm issues or sleep onset difficulty. See our related article on sleep and mental health.
How do I find CBT-I in my area?
CBT-I trained therapists, telehealth-delivered CBT-I, and digital programs (Somryst, Sleepio) all exist. Dr. Farkas can guide referrals.
