CBT-I: A Science-Based Approach to Better Sleep
If you struggle to fall asleep, wake frequently during the night, or find yourself lying awake worrying about sleep, you are not alone. Insomnia is one of the most common sleep concerns, and over time, poor sleep can affect mood, concentration, energy, and overall quality of life.
One of the most effective treatments for chronic insomnia is Cognitive Behavioral Therapy for Insomnia (CBT-I).
At Moore Psychiatry, we believe sleep is an important part of mental and physical health. CBT-I offers a structured, evidence-based approach to improving sleep by addressing the thoughts, behaviors, and patterns that can keep insomnia going.
What Is CBT-I?
CBT-I stands for Cognitive Behavioral Therapy for Insomnia.
Unlike simply being told to “get better sleep habits,” CBT-I is a structured therapeutic approach designed specifically for insomnia. It typically combines several strategies, including cognitive therapy, behavioral interventions, relaxation techniques, and sleep education.
The American Academy of Sleep Medicine strongly recommends multicomponent CBT-I for adults with chronic insomnia.
CBT-I can help you learn how to:
Reduce anxiety and frustration surrounding sleep
Change unhelpful thoughts and beliefs about sleep
Re-establish a stronger connection between your bed and sleep
Develop a more consistent sleep-wake rhythm
Spend an appropriate amount of time in bed
Reduce behaviors that unintentionally reinforce insomnia
Develop relaxation skills that support sleep
Build sustainable habits that can continue after treatment ends
Why Can't I Just Practice "Good Sleep Hygiene"?
Sleep hygiene is important, but sleep hygiene alone is not the same thing as CBT-I.
Turning down the lights, limiting caffeine, keeping your bedroom comfortable, and maintaining a consistent sleep schedule can certainly support healthy sleep. However, chronic insomnia often involves a cycle of worry, conditioned arousal, inconsistent sleep patterns, and behaviors that unintentionally maintain the problem.
For example, someone may begin spending more time in bed because they are exhausted. They may go to bed earlier, sleep in later, nap during the day, or remain in bed for hours trying to force themselves to sleep.
Over time, the bed can become associated with frustration, anxiety, and wakefulness rather than sleep.
CBT-I works to interrupt this cycle.
In fact, the American Academy of Sleep Medicine recommends CBT-I as a multicomponent treatment rather than relying on sleep hygiene as a stand-alone intervention.
The Core Components of CBT-I
1. Cognitive Therapy
When sleep becomes difficult, it is easy for thoughts about sleep to become increasingly anxious:
"I have to fall asleep right now."
"If I don't sleep tonight, tomorrow will be terrible."
"I only got four hours of sleep, so I won't be able to function."
These thoughts can increase anxiety and physiological arousal, making sleep even more difficult.
CBT-I helps identify and challenge unhelpful beliefs about sleep and replace them with more balanced, realistic ways of thinking.
2. Stimulus Control
Stimulus control helps rebuild the association between your bed and sleep.
This may include strategies such as going to bed when you are sleepy, using the bed primarily for sleep, and getting out of bed when you are unable to sleep rather than spending long periods awake and frustrated.
The goal is to help your brain relearn:
Bed = sleep, not worrying about sleep.
3. Sleep Restriction or Sleep Compression
Despite its name, sleep restriction is not intended to deprive you of sleep.
Instead, this component helps align the amount of time you spend in bed with the amount of time you are actually sleeping. As sleep becomes more consolidated, time in bed can gradually be adjusted.
Because this strategy can temporarily increase sleepiness, it is best implemented thoughtfully and, when appropriate, with guidance from a qualified healthcare professional. NHLBI describes sleep restriction as one of the components that may be used in CBT-I.
4. Relaxation Strategies
Some people become physically and mentally activated when they get into bed.
CBT-I may incorporate relaxation techniques such as:
Diaphragmatic breathing
Progressive muscle relaxation
Mindfulness
Guided imagery
Other strategies designed to reduce physiological arousal
The goal isn't necessarily to force yourself to sleep. Instead, relaxation can help create the conditions in which sleep is more likely to occur.
5. Sleep Education
Understanding sleep can reduce some of the fear and uncertainty that develops when insomnia becomes chronic.
CBT-I education may address sleep drive, circadian rhythms, sleep patterns, nighttime awakenings, and the relationship between thoughts, behaviors, and sleep.
Understanding why insomnia persists can make the treatment process feel much less mysterious.
CBT-I Can Be Especially Helpful When Anxiety Is Part of the Problem
Sleep and mental health are closely connected.
Anxiety can make it harder to sleep, while inadequate sleep can make emotional regulation and anxiety more difficult the following day. This can create a frustrating cycle:
Poor sleep → increased stress/anxiety → increased nighttime arousal → difficulty sleeping → more worry about sleep.
CBT-I helps address the sleep-related portion of this cycle by targeting the thoughts and behaviors that perpetuate insomnia.
This doesn't mean that every sleep problem is caused by anxiety. Sleep difficulties can have many contributing factors, including medical conditions, medications, hormonal changes, circadian rhythm disruptions, sleep apnea, restless legs syndrome, substance use, and environmental factors.
A comprehensive evaluation is therefore important when insomnia is persistent or significantly affecting daily functioning.
What Does CBT-I Look Like?
CBT-I is often delivered over several weeks and may involve keeping a sleep diary to better understand your individual sleep patterns.
Treatment is personalized based on factors such as:
When you typically go to bed
How long it takes you to fall asleep
How often you wake during the night
What time you wake up
How much time you spend awake in bed
Daytime sleepiness
Napping
Caffeine and other substances
Anxiety surrounding sleep
Your daily schedule and routines
NHLBI describes CBT-I as a treatment that commonly lasts approximately 6–8 weeks and notes that it can be delivered in person, by telephone, or online.
What About Sleep Medication?
CBT-I does not necessarily mean that medication is never appropriate.
Some individuals may benefit from medication as part of an individualized treatment plan. However, CBT-I addresses the underlying thoughts and behaviors that can perpetuate insomnia rather than simply attempting to make someone sleepy.
Current AASM guidance continues to support CBT-I as a core evidence-based treatment for chronic insomnia. More recent guidance also recognizes that, for some patients, CBT-I and medication may be considered together depending on individual circumstances and treatment goals.
The right approach depends on the individual, including the nature and duration of insomnia, other medical or psychiatric conditions, current medications, and personal treatment preferences.

When Should You Seek Help for Insomnia?
Consider talking with a healthcare professional if sleep difficulties are persistent, interfere with your daytime functioning, or are causing significant distress.
It is particularly important to seek evaluation if you experience symptoms such as:
Significant daytime sleepiness
Loud snoring or gasping during sleep
Persistent nighttime anxiety
Restless or uncomfortable sensations in the legs
Frequent nighttime awakenings
Major changes in sleep patterns
Sleep difficulties that began after starting a medication
Insomnia lasting several months
A healthcare professional can help determine whether insomnia is occurring on its own or alongside another condition that may need to be addressed.
Better Sleep Is More Than "Trying Harder"
One of the most frustrating things about insomnia is that trying harder to sleep can sometimes make sleep more difficult.
CBT-I takes a different approach.
Rather than fighting sleep, watching the clock, or worrying about how many hours remain before morning, CBT-I helps you understand the factors maintaining insomnia and gradually retrain your relationship with sleep.
For many people, improving sleep isn't about finding the perfect supplement, sleep gadget, or bedtime routine. It is about changing the cycle that has developed around sleep.
If insomnia has become a source of stress in your life, CBT-I may be worth exploring.
At Moore Psychiatry, we view sleep as an important part of an integrative approach to mental health and overall well-being.
