Session 3
Cognitive Restructuring and Sleep
Medication Reduction Techniques
Lesson 1: Introduction to Cognitive Restructuring
Negative Thoughts About Sleep
A major problem with insomnia is the worry that it will affect you the next day. Negative, stressful
thoughts about sleep worsen insomnia by triggering emotions such as anxiety or frustration that
mobilize the stress response. In turn, the stress response strengthens the wakefulness system,
weakens the sleep system, and makes it harder to sleep. And the harder it is to sleep, the more
anxious one feels about not sleeping!
NEGATIVE SLEEP THOUGHTS
INSOMNIA
Here are some examples of negative sleep thoughts that are very common:
I must get eight hours of sleep.
I will not be able to function tomorrow.
My insomnia is going to cause health problems.
I cannot fall asleep without a sleeping pill.
I did not sleep at all last night.
Recognizing and Changing Negative Sleep Thoughts
As you will learn in this session, negative sleep thoughts are usually distorted and inaccurate.
They only make your insomnia worse.
You can overcome insomnia by learning to recognize and change your negative sleep thoughts
with cognitive restructuring. Cognitive restructuring means replacing negative sleep thoughts with
more helpful, accurate thoughts about sleep. The goal of cognitive restructuring is simple yet
powerful: by recognizing and replacing your negative sleep thoughts with more accurate, positive
thoughts about sleep, you will reduce worry and other negative emotions that trigger the stress
response and disturb your sleep. The more you practice cognitive restructuring, the better you will
sleep.
Keep in mind that cognitive restructuring is not the same as pretending you don’t have insomnia
or simply using the power of positive thinking. It means thinking about insomnia less negatively
and more accurately.
Scientific Findings: Sleep and Insomnia
To recognize and replace your negative sleep thoughts with more accurate, positive thoughts
about sleep, you must first learn about some important scientific findings concerning several
aspects of sleep and insomnia:
Sleep duration, health, and daytime functioning
The effects of sleep loss on daytime performance
How much sleep you think you are getting
Lesson 2: Sleep Duration, Health, and Daytime Functioning
The Eight Hour Sleep Myth
Although many people think that we need at least eight hours of sleep to stay healthy, recent
studies show that people who sleep seven hours live longer than people who sleep eight:
Three studies involving over a million people demonstrated that people who sleep seven
hours per night have the lowest death rates and those who sleep eight or more hours per
night have progressively increasing rates of death.
The studies showed that sleeping five hours per night is associated with longer life
expectancy than sleeping nine hours per night.
All three studies are in agreement that long sleep is associated with greater mortality than
short sleep.
The findings of these three studies involving enormous samples (up to one million
people) are consistent with a dozen smaller studies, and no persuasive studies have
contradicted these findings.
Key Concept: This means that you do not have to worry about getting eight hours of sleep
per night to stay healthy.
Similarly, many of us do not need eight hours of sleep to function effectively during the day:
Many individuals cannot sleep eight hours even if they try.
The amount of sleep that we need to feel alert during the day varies from person to
person. The majority of adults sleep less than eight hours per night and report feeling
rested during the day.
If we needed eight hours of sleep, we would expect adults to average about eight hours
of sleep but this is not the case: adults average about seven hours of sleep.
The majority of adults who sleep less than eight hours report positive mood during the
day, feel optimistic, and are satisfied with their lives.
Key Concept: This means that you do not have to worry about getting eight hours of sleep
per night to function effectively during the day.
Sleep Loss and Daytime Performance
What about the effects of sleep loss on daytime performance? Although research shows that not
getting enough sleep can make it harder to do your normal daily tasks, the effects of sleep loss
also depends upon how much sleep is lost and how often it happens. Research also shows that:
Everyone is different. Some people are affected a lot by sleep loss while others may be
affected very little.
Some individuals show a remarkable tolerance for sleep loss, particularly if the person is
motivated to cope with sleep loss (such as caring for a newborn) or the sleep loss occurs
under positive circumstances (such as a vacation or a party).
Some of the effects of sleep loss may actually be due to the effects of stress that led to
the sleep loss. In fact, stress has been shown to have much greater effects on our
functioning than sleep loss.
Most studies on sleep deprivation are typically on young, healthy, eight-hour sleepers
who are restricted to four hours of sleep. However, these younger eight hour sleepers are
more susceptible to the effects of sleep loss than shorter sleepers or older sleepers.
Studies on insomnia patients show that sleep loss does not affect them as much as
normal sleepers.
Key Concept: This means that sleep loss does not always have adverse effects on daytime
functioning.
Lesson 3: Sleep Loss and “Core” Sleep
Core Sleep
Now let’s explore the concept of core sleep. Research also suggests that many individuals can
maintain performance for extended periods of time on about five and half hours of sleep, or what
some sleep researchers call “Core Sleep”:
People who need to maintain performance under challenging circumstances -such as
rescue workers, armed services personnel, physicians, and solo yacht racers - can
maintain their performance with five to six hours of sleep.
Studies on insomnia patients show that they average just under six hours of sleep yet do
not have poorer daytime performance or alertness than good sleepers.
The reason core sleep can maintain performance in those who suffer from insomnia is
that it contains 100 percent of our deep sleep (the most important stage of sleep) and fifty
percent of our dream sleep (the second most important stage of sleep).
Core sleep does not have to be obtained continuously (that is, we can sleep for two
hours, be awake for an hour, and then sleep three or four more hours). Also, your brain is
“programmed” to get core sleep (that is, it will do its best to obtain core sleep each night).
Key Concept: This is not to say that we only need core sleep, since most people need
additional sleep to feel their best. However, it does mean that your performance will
usually not suffer significantly if you obtain core sleep.
Lesson 4: Perceived vs. Actual Sleep Duration
You Are Getting More Sleep Than You Think
Research shows that people with insomnia are getting more sleep than they think:
They overestimate how long it takes to fall asleep and how long they are awake during
the night.
They underestimate how much sleep they get.
This misperception of sleep is because they perceive stage 2 sleep as wakefulness; and, the fact
that time perception is altered under the stressful circumstances of lying awake. As a result,
perception of time seems longer than actual clock time.
Key Concept: This means that, by recognizing you are likely getting more sleep than you
think, you will reduce negative sleep thoughts and sleep better.
Lesson 5: Insomnia and Daytime Mood
Finally, let’s take a look at the relationship between insomnia and daytime mood.
It’s going to be a miserable day
because I didn’t sleep well
You may notice that the biggest effect of insomnia is on your mood the following day. You may
feel irritable, worried, tired, or a little depressed. This is important to know for changing your
negative sleep thoughts:
In most cases, it is only your mood that may be affected for the day after a bad night’s
sleep.
It is not just how much sleep you lose that affects your daytime functioning but also your
negative thoughts about your sleep loss. If you can reduce negative thoughts about your
sleep loss, you will reduce the effects of insomnia on your daytime mood and functioning.
If you wake up and begin your day with a negative sleep thought such as “The day is
going to be miserable because I did not sleep well”, it is the combination of sleep loss
and negative mood from this thought that affects your daytime functioning. You can
prove this to yourself by noticing that sleep loss due to positive events (such as parties,
vacation, etc.) does not have as much of a negative impact on daytime functioning.
Lesson 6: Practicing Cognitive Restructuring
Now that you have spent some time learning about the scientific findings concerning sleep and
insomnia, you are ready to practice cognitive restructuring each day to reduce your negative
sleep thoughts and improve your sleep and your daytime mood.
Your Negative Sleep Thoughts
To begin, you can identify your most frequent negative sleep thoughts using the list below. For
each negative sleep thought, you will be given positive sleep thoughts that you can use to replace
those negative sleep thoughts. The positive sleep thoughts that you will be given are based on
the information you just learned about involving sleep, health, and performance; and, on the
information we reviewed in Session 1 concerning basic facts about sleep and sleeping pills.
You will begin to use these positive sleep thoughts each day to replace your negative sleep
thoughts. Review them regularly. It may be helpful to write them down, print them or keep them
by your bed to refer to at night or when you wake up in the morning.
The 10 Most Common Negative Sleep Thoughts
Now, choose the negative sleep thoughts from the following list that are similar to those you
experience most frequently, then review the positive sleep thoughts on the next page that you
can use to replace those specific thoughts:
I will never fall asleep.
I woke up in the middle of the night/early morning and feel wide awake. This means I
will not be able to fall back to sleep.
I will not be able to function tomorrow.
I must get eight hours of sleep.
My insomnia is going to cause health problems.
I did not sleep at all last night.
I cannot fall asleep without a sleeping pill.
I feel terrible today due to my insomnia.
I will never learn to sleep better.
What is wrong with me? I must have a psychological problem.
Positive Sleep Thoughts That You Can Use to Replace Specific Negative Sleep Thoughts
Positive Sleep Thoughts
To Replace
Negative Sleep Thoughts
I will never fall asleep
I am more likely to fall asleep as my body temperature falls throughout the night.
My brain wants to obtain my core sleep.
I woke up in the middle of the night or early morning and feel wide awake. This means I
will not be able to fall back to sleep.
It is normal to initially feel alert if I awaken at the beginning or end of dream; drowsiness
will soon follow.
If I awaken after about five and a half hours of sleep, I obtained my core sleep. If I do not
fall back to sleep, I will be okay.
I will not be able to function tomorrow.
In most cases, the worst thing that may happen if I do not sleep well is that I may not be
in the best mood during the day.
Sleep loss does not always have a significant impact on my daytime functioning.
I can handle sleep loss, especially if it is only happening a few nights per week.
My performance will not suffer significantly if I get my core sleep.
My functioning will improve during the day as my body temperature rises.
I must get eight hours of sleep.
Sleep requirements vary from person to person.
Sleeping seven hours per night is associated with the longest life expectancy.
My insomnia will cause health problems.
There is no cause-and-effect evidence that insomnia causes any significant health
problems.
I slept very little or not at all last night.
I am probably getting more sleep than I think I am.
I cannot fall asleep without a sleeping pill.
As I learn these CBT techniques, I will fall asleep more easily on my own.
I am better off without sleeping pills since many of them cause a hangover effect and
reduce my deep sleep.
Sleeping pills do not work that well anyway, since part of their effect is actually a placebo
effect.
It will become easier to fall asleep without a sleeping pill the more I try it.
I feel awful today because I did not sleep well.
My daytime functioning is due in part to my negative sleep thoughts. If I minimize my
negative sleep thoughts, I will improve my daytime functioning.
My daytime functioning is not just affected by my sleep.
I will never learn to sleep better.
These techniques work for most people with insomnia, they will work for me.
My sleep will get better as I learn these CBT techniques.
What is wrong with me? I must have a psychological problem
Most cases of insomnia are due to learned thoughts and behaviors, not mental health
problems.
Insomnia is very common. It affects over half of adults.
Lesson 7: Sleeping Pills
Putting Sleeping Pills to Rest
If you are taking sleep medication and you want to reduce the amount you are taking, you are
ready to begin sleep medication reduction techniques along with the cognitive restructuring
techniques this week.
Several studies on CBT have shown that 50% of people who regularly use sleep medication
reduce the amount they take and the other 50% stop entirely. Two important elements aid the
success of these sleep medication reduction techniques:
You can reduce sleeping pill use at your own pace.
The techniques allow you to gradually decrease sleep medication rather than stopping
abruptly cold turkey, which can backfire and cause increased anxiety and insomnia.
Putting Sleeping Pills to Rest
Since regular users of sleeping pills can experience withdrawal symptoms or rebound insomnia if
they stop sleeping pill use abruptly, gradually tapering sleeping pill use minimizes the likelihood of
these problems. Be sure to discuss these medication reduction guidelines with your physician.
Here are the sleep medication reduction techniques:
First, begin by determining the number of nights you generally use sleeping pills during the week,
and the typical number of pills on those nights.
Next, reduce the number of pills you are taking by one-half on two nights this week. Space the
two nights apart.
If you are only taking one pill, cut the dose in half and consider this a half pill.
Choose easier nights when there is little pressure or work obligations the following day.
Use positive sleep thoughts that we have explored such as “In most cases, the worst
thing that may happen if I do not sleep well is that I may not be in the best mood during
the day”.
Once you are sleeping reasonably well on the two reduced pill nights (this may happen
immediately or may take a week or two), you will feel more confident about reducing sleep
medication and can then:
Reduce the number of pills by half on two more nights during the week.
Space these four medication reduction nights apart (e.g., every other night).
Continue in this way until you have reduced the number of pills you take by half on all of the
nights that you typically take sleep medication (you will eventually have to take the half dose on
consecutive nights). Avoid going back to the original dose.
Once you have reduced the number of pills you take by one-half, begin to go medication-free in
the same gradual fashion:
No medication two nights a week
Then no medication two more nights
Then no medication every night
Examples of Sleep Medication Tapering
I take a sleeping pill every night. Therefore:
I will pick two nights this week and take half a pill.
My next goal will be to take half a pill every other night, then every night.
Once I am down to half a pill nightly, I will not take a pill on two nights a week, then every
other night, then every night.
I take a sleeping pill four nights per week. Therefore:
I will pick two nights this week and take half a pill.
My next goal will be to take half a pill on all four nights per week.
Once I am down to a half pill on the four nights I take a sleeping pill, I will not take a pill
on two nights a week, and then I will stop altogether.
I take two sleeping pills every night. Therefore:
I will pick two nights this week and take one pill.
My next goal will be to take one pill every other night, then every night.
Once I am down to one pill nightly, I will take a half pill on two nights a week, then every
other night, then every night. Then I will not take a pill on two nights a week, then every
other night, then every night.
Lesson 8: Week #3 Goals
In addition to your goals from the prior week, your new goals this week are to:
1. Begin using your positive sleep thoughts to replace your negative sleep thoughts.
2. Work on your sleep medication reduction goal.
3. When you have completed all seven nights on your sleep diary, e-mail it to Dr. Jacobs to
receive your individualized sleep scheduling guidelines. Then go on to Session 4.
Tips for meeting these goals:
To help you practice cognitive restructuring for negative sleep thoughts:
Review this session again on the importance of cognitive restructuring.
Post your positive sleep thoughts on your mirror, keep them by your bed, etc.
To help you reduce sleep medication:
Review Session 1 on the drawbacks of sleeping pills.
Use positive sleep thoughts such as “This will get easier with practice”, “Sleep
medications do not work that well anyway”, or “Part of the effect of sleep medications is
the placebo effect.”
