CBT-I is usually delivered through weekly or bi-weekly sessions over a period of between 4 and 8 weeks.
CBT-I works by addressing the thoughts and behaviors that are the root cause of most cases of insomnia. The techniques used include:
Sleep education
Sleep education is included in a course of CBT-I to help you address incorrect thoughts about sleep and better understand how your behaviors affect sleep.
Having a better understanding of sleep can reduce sleep-related worries and anxiety, and therefore improve the likelihood of sleep.
Cognitive restructuring
This is a fancy way of saying ‘changing the way you think’. Cognitive restructuring will address (and help correct) certain ways of thinking that are unrealistic and inaccurate. We often have inaccurate assumptions about things. Cognitive restructuring helps correct these inaccuracies by proving that the opinions we have (even when we are absolutely sure about them and can easily justify them) may not be accurate.
Sleep restriction
When clients enroll in the Insomnia Coach course, I usually find that they are spending far more time in bed awake than asleep. Sleep restriction reduces the amount of time spent in bed to more closely match the amount of time spent asleep. The phrase ‘sleep restriction’ isn’t the greatest because it suggests that sleep is being reduced. When sleep restriction is done correctly it rarely leads to less sleep.
Stimulus control
This is another scientific phrase that could be changed to be more easily understood! I prefer to use the term ‘sleep reconditioning’ because the aim of stimulus control is to make the bed a trigger for sleep. For many people with insomnia, the bed has become a place of wakefulness and all of the difficult emotions associated with insomnia. The result? Whenever you get in bed (or think about the bed) you don’t see the bed as a place for sleep. Stimulus control corrects this by retraining the mind to see the bed as a place for sleep. This is done by using the bed for nothing other than sleep (or sex) and by getting out of bed when you can’t sleep.
Relaxation techniques
A common complaint among those with insomnia is being unable to sleep because of an active or racing mind. A lot of people who find it hard to sleep say that they can’t shut down their minds at night. Relaxation can help to calm the mind and make sleep more likely. A course of CBT-I usually includes at least one type of relaxation technique for the client to practice. Relaxation techniques for sleep include:
It’s worth bearing in mind that the goal of relaxation is relaxation — not sleep! However, as you become more relaxed, sleep becomes more likely. It’s also important to note that relaxation is a skill. Relaxation rarely works when first tried. It takes a lot of practice.
Sleep hygiene
As you have probably realized, cognitive behavioral therapy for insomnia is a lot more than just sleep hygiene! A lot of people think that CBT-I is the same thing as sleep hygiene. It isn’t. Sleep hygiene is unlikely to improve your sleep if you are living with chronic insomnia. For this reason, sleep hygiene is usually included in a course of CBT-I but it is not the focus (in my online course for insomnia, I don’t even cover sleep hygiene).
Relapse prevention
Finally, a good course of CBT-I should teach you what to do if your insomnia returns. This will help prevent any future sleep issues from developing into insomnia.
