Part 2 of Our Science Series | CBT-I, or cognitive behavioral therapy for insomnia, is the gold standard for treating insomnia. Learn more about CBT-I and how it works.
CBT-I, or cognitive behavioral therapy for insomnia, is the gold standard for treating insomnia. It is theย most effective known treatment for insomnia and has been proven to work for as many as 70% to 80% of patientsย with primary insomnia in clinical trials. Improvements include less time to fall asleep, more time spent asleep, and waking up less during sleep. Unlike sleeping pills, the improvements from CBT-I are maintained over time. This is why both the American College of Physicians and the American Academy of Sleep Medicine recommends CBT-I as a first-line treatment for insomnia patients.
Before we dive into how CBT-I works, it is important to clarify that CBT-I is NOT about sleep hygiene. This is a popular misconception. While common advice such as โavoid caffeine after 4pmโ, โlimit alcohol in the evening to no more than 2 drinks before 7pmโ or โminimize the use of blue-light emitting devices an hour before sleepโ are helpful, there isย little evidence that sleep hygiene alone is sufficient to treat insomnia.
For any insomnia treatment to be effective in the long-term, it needs to address the root causes behind sleeplessness (recall Spielmanโs 3 Pโs Model fromย Part 1). Traditionally, CBT-I is a multicomponent treatment that combines several approaches, includingย cognitive restructuring,ย stimulus control, andย sleep restriction.
A core principle in CBT-I is that the way we sleep is influenced by our thoughts and feelings about sleep. People with insomnia often have dysfunctional thoughts about sleep that result in behaviors that are detrimental to good sleep.
Cognitive restructuring attempts to break this destructive feedback loop byย identifying, challenging and reframing the thoughts and feelings that contribute to insomnia. For example, many insomniacs have distortive thoughts such as thinking โOh my god, itโs been 15 minutes but I still havenโt fallen asleep. Iโm never going to be able to fall asleepโ. These thoughts, in addition to being logically wrong, also create a negative stress cycle where the longer you canโt fall asleep, the more you think these thoughts, the more stressed you become, and the more unlikely you are to fall asleep soon.
Cognitive restructuring equips patients with the tools and skills to challenge and alter their dysfunctional thoughts and feelings. This usually takes the form of structured exercises that require active participation from the patient.
Stimulus control is based on the psychology of conditioning. Classical conditioning was first studied by the Russian scientist Ivan Pavlov in 1897. Pavlov observed in a series of experiments with dogs that he can provoke a conditioned response (salivation) to a previously neutral stimulus (a bell ringing). Similarly, people with insomnia often associate wakefulness (conditioned response) to their bedroom (stimulus) due to habits such as reading, watching TV or using devices in bed.
Stimulus control aims to break these associations byย reclaiming the bedroom as a sanctuary for restorative sleep. Some guidelines for stimulus control include:
You will also learn to recognize the difference between being tired and being sleepy, so you only go to bed when youโre sleepy (and not just tired).
Sleep restriction therapy is one of the most powerful tools in sleep psychology and has been extensively researched.ย People with insomnia often find it counterintuitive that you have to try to stay awake in order to get better sleep, but this is fundamental psychology at work. Youโre so sleepy by the time you hit the pillow that you immediately fall into a deep, restorative sleep. In time, your mind starts forming a strong, permanent association between your bed and quickly falling into a restorative sleep. This association will benefit your sleep for the rest of your life.
The way sleep restriction works is by narrowing your sleep window at the beginning of treatment to increase sleep efficiency, or the ratio of time asleep to time-in-bed.ย Your sleep window is then gradually adjusted in each subsequent session so that you would be able to achieve your sleep goals eventually. There are techniques used by sleep clinics to calibrate your time-in-bed on a regular basis, using your past sleep data and combining it with results from a sleep questionnaire.
Increasingly, relaxation techniques such as breathing exercises, progressive muscle relaxation, guided imageries and meditation are also introduced to supplement CBT-I during treatment. Patients learn and practice techniques to regulate their heart-rate and breathing, relax specific muscle groups in the body, and observe their subconscious mind.ย Benefits include reduced stress and anxiety, and achieving a state of hyper-relaxation that is conducive to restorative sleep.
Stellar Sleepโs digital CBT-I program is rooted in the same clinically-proven practices used during in-person CBT-I. We combine the traditional CBT-I program with content personalization and relaxation exercises, to create what is probably the most effective treatment for insomnia that is available, and we have the data to back this up. Moreover, our program makes it convenient for you to access treatment anytime and progress at your own pace, all from the comfort of your smartphone. Inย Part 3, which is also the final part in this deep dive series, we will tell you more about what you can expect from the Stellar Sleep program.
