How do I know whether I need CBT-I or just better sleep habits?

Sleep hygiene focuses on general practices that support sleep, such as managing caffeine, maintaining a comfortable sleep environment, and allowing enough time for sleep. Those practices matter, but many people with chronic insomnia already know them.

CBT-I addresses the processes that keep insomnia going. Depending on the person, treatment may include:

• Reviewing sleep patterns with a sleep diary
• Adjusting time in bed to strengthen sleep consolidation
• Rebuilding the association between bed and sleep
• Reducing sleep-related monitoring, effort, and fear
• Working with thoughts that increase nighttime arousal
• Developing strategies for difficult nights and future disruptions

The distinction matters because insomnia is not always caused by poor sleep habits. A person may have an excellent bedroom routine and still experience conditioned arousal, an irregular sleep window, circadian misalignment, medication effects, pain, anxiety about sleep, or another sleep disorder.

Consider seeking an evaluation when sleep difficulty:

• Persists despite reasonable sleep habits
• Happens regularly rather than occasionally
• Affects mood, concentration, energy, performance, or safety
• Creates increasing fear or effort around bedtime
• Leads to spending substantially more time in bed trying to sleep
• Occurs alongside snoring, gasping, uncomfortable leg sensations, unusual nighttime behavior, or severe daytime sleepiness

A behavioral sleep medicine evaluation should also consider whether insomnia is the primary problem or whether another medical, circadian, psychiatric, or sleep condition needs attention.

CBT-I is a structured treatment, not a collection of generic sleep tips. The goal is to understand what is maintaining the sleep problem and choose interventions that fit that mechanism.
