← Media · Sleep → Insomnia

If insomnia has been hanging on for months, this is the straight version: CBT‑I is usually first-line treatment. Not because medication is "bad," but because CBT‑I treats the pattern that keeps insomnia alive. Medications can help as short-term scaffolding; CBT‑I is the foundation.

What it is (one mental model)

CBT‑I is a structured treatment, usually 6 to 8 sessions. It targets the core drivers of chronic insomnia: too much wake time in bed, a weak bed-sleep association, and anxious sleep thoughts. We do not force sleep. We reset sleep pressure, timing, and conditioning so sleep can consolidate naturally.

Why first-line (the evidence)

CBT‑I improves sleep onset, wake after sleep onset, and sleep efficiency in most patients. It performs similarly to sleep medication early on, but the gains are more durable after treatment ends. Long-term sedative use can lose effect and may add tolerance or dependence risk. That is why major guidelines prioritize CBT‑I first, with medication used selectively and time-limited when needed.

CBT‑I also works when insomnia occurs with other conditions, including sleep apnea, depression, anxiety, chronic pain, and PTSD. Comorbidity is not a reason to skip it.

What CBT‑I typically includes (action ladder)

• Education — Sleep drive, circadian rhythm, and the pattern that perpetuates insomnia.
• Sleep compression/restriction — Match time in bed to actual sleep, then expand gradually as efficiency improves.
• Stimulus control — Bed for sleep and sex only; if awake and frustrated, get up and reset.
• Cognitive work — Untangle rigid beliefs and catastrophic predictions about sleep.
• Wind-down routine — A repeatable pre-bed sequence that lowers arousal.
• Medication taper when appropriate — Planned, gradual taper once behavioral skills are stable.

When to see a pro. If insomnia has lasted more than a few months or self-help has stalled, get a formal evaluation. A clinician can rule out other sleep disorders, review medications, and build a personalized CBT‑I plan.

Common traps

Wrong assumption: "CBT‑I is just sleep hygiene." It is not. Sleep hygiene helps, but CBT‑I adds the active components that change outcomes.

Common detour: Relying on nightly medication without a skills plan. Medication may help symptoms now, but skills are what protect sleep long-term.

Bottom line

• CBT‑I is first-line for chronic insomnia because it treats the mechanism, not just symptoms.
• Medication can be useful short-term, but should usually be paired with a plan to build and maintain CBT‑I skills.
• If insomnia is persistent, seek evaluation and structured care. See Choosing Wisely for AASM recommendations on sleep medications.
