The Insomnia Treatment Every Guideline Recommends First Isn't a Pill

Cognitive Behavioral Therapy for Insomnia (CBT-I) retrains the sleep-related thoughts and behaviors — stimulus control, sleep restriction, cognitive restructuring — that perpetuate chronic insomnia. Melatonin supplies a hormone your body already produces to signal circadian timing, useful for shifting the sleep-wake clock, not necessarily for building sleep-maintaining habits.

What the guidelines actually recommend

Clinical guidelines, including strong 2025 endorsements, unanimously recommend multicomponent CBT-I as first-line treatment for chronic insomnia. Its efficacy is similar to sleep medication short-term, but more durable after treatment ends, with a far better safety profile.¹

Where melatonin actually fits

Melatonin, by contrast, has mixed and generally low-quality evidence for treating chronic insomnia specifically, despite widespread use.² One RCT in a specific population — people with neurodevelopmental conditions — found melatonin alone or combined with CBT-I outperformed CBT-I alone, a reminder that population matters.

Why the distinction matters

CBT-I addresses the habits and thought patterns that keep chronic insomnia going. Melatonin addresses circadian timing — a different problem. Using melatonin for general sleep-maintenance insomnia is treating the wrong mechanism for most people.

The practical takeaway

• CBT-I (increasingly available via app-based or therapist-led programs) is the better-evidenced first move for ongoing insomnia
• Melatonin is more consistently useful for jet lag or shift work than for general sleep-maintenance insomnia
• Talk to a doctor about which approach fits your specific sleep problem before starting either
