Good News! You May Be Getting More Sleep Than You Think, Especially If You Suffer Insomnia!

Send to Kindle

The Wall Street Journal today had a very interesting article about how people with insomnia tend to greatly underestimate how much sleep they get and overestimate how long it takes them to fall asleep. They also overestimate how often they wake up at night.

Roughly 30% of adults have some insomnia each year. About 10% of people have chronic insomnia which means that you have trouble sleeping three times a week or more. According to the Journal article, 42% of insomniacs who actually slept the normal amount (6 hours or more) underestimated how much they slept by more than an hour. I looked up the research article which was published in Psychosomatic Medicine. According to this research, insomniacs who slept six hours or more typically showed a profile of high depression and anxiety and low coping skills according to psychological testing.

What’s also interesting is that even though insomniacs may be sleeping six or more hours a night, there does appear to be some real differences in their brainwave activity compared to good sleepers. Even though they are asleep, their brains are more active, which may account for why they perceive their sleep to be less than it really is.

Another interesting factoid was that normal people tend to overestimate how much sleep they get. Most people when asked how much sleep they get will answer between seven and eight hours, but they are actually getting six hours. That’s why people tend to be so sleep deprived. For most people six hours is not enough sleep to feel really good.

So what’s the answer to this sleep estimating dilemma? It turns out there is a very simple answer. The two gold standards for measuring sleep are brainwave measurements and activity measurements. While brainwave measurements are difficult to come by in the home, activity measurements are very easy and inexpensive to obtain. Many of the current fitness tracker’s have a sleep tracking function. For instance, according to my Xiaomi Mi Band, which cost me the grand sum of $15, last night I was in bed for seven hours and 58 minutes, and got three hours 20 minutes of deep sleep and four hours and 38 minutes of light sleep. I was awake for one minute. (Yes, I know, please don’t hate me all you insomniacs!)

For insomniacs who worry about how much sleep they are getting, I recommend buying a fitness tracker and wearing it every night. The best ones automatically track sleep without having the requirement that you push a button to activate sleep mode. This is pretty important as most people forget to press the button. I have been pretty happy with my Xiaomi Mi Band, which you can buy directly from the company  but I’m sure there are other brands of fitness trackers which offer similar features.

Also, as I’ve written about previously here and here, cognitive behavioral therapy for insomnia (CBT-I) may also improve the quality of sleep as well as the quantity. Some studies show that CBT-I improves people’s ability to accurately estimate their sleep time, and it also may calm  the over-activity of the brain that occurs when insomniacs sleep.

So here’s the executive summary for all of you sleep-deprived folks:

1. If you are an insomniac who is anxious and depressed, then you are probably getting more sleep than you think. Buy a fitness tracker with a good sleep tracking function, and you will see how much sleep you are actually getting.

2. If you want to improve the quality of your sleep, either practice meditation or see a CBT psychologist for CBT-I, as both of these interventions seem to lower the activity of the brain during sleep, which will improve your perception of your own sleep.

3. If you consistently feel anxious or depressed, consider getting some cognitive behavioral therapy for these problems, as they may contribute to sleep difficulties.

I’m off to bed now and hope I don’t have insomnia now that I’ve written about it!

Cognitive Behavioral Therapy for Insomnia (CBT-I) Outperforms Drugs for Insomnia

Send to Kindle

The New York Times today had an excellent article The Evidence Points to a Better Way, which summarized what I have written about before. Cognitive behavioral therapy for chronic insomnia (CBT-I) kicks the butt of drug therapy!

One study compared CBT with a common sleeping pill called Restoril and found that the CBT treatment led to larger and longer lasting improvements in sleep. Another study found that CBT treatment outperformed the drug Ambien, and that CBT alone was even better than CBT plus Ambien combined.

Even more impressive are the results of a large meta-study which was published today. This meta-study, which combined data from 20 clinical trials and involved over 1000 patients with chronic insomnia showed that CBT I resulted in these patients falling asleep 19 minutes faster and having 26 minutes less wakefulness during each night on average. The actual study is protected by a pay wall, but the summary results are here.

One might question the clinical relevance of these outcomes. Does falling asleep 19 minutes faster really make that much of a difference? Does sleeping an extra 26 minutes a night make patients feel better the next day? As a good sleeper, I don’t really know the answer to these questions.

But I suspect that the biggest impact of CBT-I is in affecting the person’s perception of control over sleep. One of the horrible things about chronic insomnia is that patients feel out of control in terms of their sleep. They worry tremendously about the impact of loss of sleep on their ability to function the next day. It is this worry cycle that actually can create insomnia.

So I suspect that even though the effects were durable but modest, that the overall treatment made a large difference in how people felt. There is a big difference between taking 45 minutes to fall sleep and 20 minutes to fall sleep. And I suspect that sleeping an extra 26 minutes a night actually does make a difference. I know that I feel much better on eight hours of sleep as opposed to 7.5 hours of sleep.

When I work with patients on CBT-I one of the things I work on is helping the patient lower their anxiety about the impact of sleep restriction. As crazy as it sounds, one of the interventions I typically use is to have the patient stay up all night and go to work the next day. Although they are typically very tired, they discover that they can focus and function, maybe not at 100% but at an adequate level, maybe 75% or so. This lowers a lot of the anxiety about insomnia, since even a bad night of insomnia typically leads to quite a bit more sleep than staying up all night.

Other than the time and energy that a patient must invest in learning CBT-I skills, there are no side effects of cognitive behavioral therapy for insomnia. All sleeping medications have significant side effects the most troubling of which involve impaired cognition and coordination during the night and the following day. This impaired coordination and cognition leads to increased falling in the elderly, and probably also leads to an increase in automobile and other accidents. Because drug companies don’t want studies done on this issue, there are relatively few studies, but one study in Norway found that there was a doubling of traffic accidents among patients who took a variety of sleeping pills. Another study that compared 10,000 sleeping pill users to 23,000 nonusers found that the sleeping pill users were five times more likely to die young than nonusers.

So what does this mean to the person suffering insomnia? It means that you should avoid taking sleeping medications, and get cognitive behavioral therapy for insomnia. This kind of therapy typically does not take very many sessions. I teach the basic skills of CBT-I in about 4 to 6 sessions, and typically the entire course of CBT-I takes less than 10 sessions. There are also options for CBT- I online and even apps that run on your phone. One such app that runs on both android and iPhone is called CBT-I Coach. This app was developed with your tax dollars as part of a large Veterans Administration insomnia treatment program, and is excellent.

It’s getting late, so rather than have to experiment with any of these treatments, I’m off to bed…

Want to Sleep Better? Get Brief CBT-I Therapy for Sleep Instead of Sleeping Pills

Send to Kindle

“To sleep–perchance to dream. Ay, there’s the rub”

The New York Times reported on a terrific study at the University of Pittsburgh, looking at ultra short treatment of insomnia in the elderly. According to the article roughly 1/4 of older adults suffer from insomnia. The researchers streamlined an approach called CBT-I, which stands for cognitive behavioral therapy of insomnia.

There were only two sessions of treatment, totaling about 90 minutes. There were also two brief follow-up phone calls, over the first month. They tested this brief treatment and 79 seniors with chronic insomnia.

So what were the results of this study? They couldn’t have been very powerful, right?

Wrong. Two thirds of the CBT-I group reported a clear improvement in sleep, compared with only 25% of the people in the control group. Even better, 55% were cured of their insomnia. And six months later the results were even better.

So what was this magic treatment and the magic rules for curing insomnia? There were only four rules.

  • Spend only seven or eight hours in bed.
  • Set your alarm and get up at the same time everyday.
  • Never go to bed until you actually feel sleepy.
  • If you are tossing and turning and can’t sleep, get out of bed and do something relaxing until you get sleepy again. Then go back to bed.

These are standard cognitive behavioral sleep hygiene rules. And they are very powerful. Although not mentioned in the study, a few other rules are also helpful.

  • Regular exercise performed no later than midday is also helpful.
  • Reducing caffeine, nicotine, and alcohol all are helpful.
  • Avoid all naps.
  • Only use your bedroom for sleep and sex. Don’t watch TV or read in bed.

So why isn’t this treatment widely available? Could it be because there isn’t a powerful drug lobby for sleeping pills pushing this very effective therapy?

What is really tragic is that most seniors end up being prescribed sleeping pills for insomnia. And this is in spite of very clear data from research that shows that modern sleeping pills such as Ambien, Lunesta, or Sonata, have very minimal effects. On average they reduced the average time to fall asleep by 12.8 minutes compared to placebo, and increased the total sleeping time by only 11.4 minutes.

Patients who took older sleeping medications like Halcion and Restoril fell asleep 10 minutes faster, and slept 32 minutes longer.

How can this be? Why is it that patients believe that sleeping pills are much more effective? The answer is very simple. All of these drugs produce a condition called anterograde amnesia. This means that you cannot form memories under the influence of these drugs. So you don’t remember tossing and turning.  If you can’t remember tossing and turning even though you may have, then you perceive your sleep has been better. The drugs also tend to reduce anxiety, so people worry less about having insomnia, and thus feel better.

The hazards of sleeping pills in older adults include cognitive impairment, poor balance, and an increased risk of falling. One study in the Journal of the American geriatrics Society found that even after being awake for two hours in the morning, elder adults who took Ambien the night before failed a simple balance test at the rate of 57% compared to 0% in the group who took placebo. This is pretty serious impairment. Interestingly enough, in the same study, even young adults who took Ambien showed impaired balance in the morning.

So what are the key messages here?

1. Even though sleeping pills give people a sense of perceived improvement in sleep, the actual improvement tends to be almost insignificant, especially with the newer and very expensive sleeping medications. The older medications increased sleep time a little better, but have more issues with addiction and tolerance. Side effects of these medications are potentially very worrisome, since they can cause cognitive impairment and increased falling which leads to injuries, especially in the elderly. Why risk these side effects for such small improvements in sleep quality?

2. Cognitive behavioral therapy for insomnia works better than sleeping pills, has no side effects, is cheaper in the long run, and has a lasting impact on sleep improvement.

3. Most people who suffer insomnia will see their physician, who will prescribe sleeping pills. This is partly because of the lack of availability of cognitive behavioral treatment for insomnia. There are relatively few cognitive behavioral practitioners, and even fewer who regularly do CBT-I. We need to improve the availability of these treatments, and should follow in the footsteps of the University of Pittsburgh researchers in learning how to streamline these treatments. Most people don’t have the patience to spend 6 to 8 weeks in cognitive behavioral therapy for insomnia. Instead we need treatments that can be administered in a single week or two with some brief follow-up.

4. CBT-I availability will always suffer from the fact that there is no powerful corporate interest backing it. There are no CBT-I sales reps going to doctors offices offering free samples of CBT-I for doctors to pass out to their patients. I don’t have a solution for this problem, but would be interested in hearing from my readers as to how we might more effectively promote effective and safe treatments such as CBT-I.

Okay, now that I’ve written this, it’s time to trundle off to bed. As Hamlet said, “To sleep — perchance to dream. Ay, there’s the rub!”
