Sleep Tracking? No. Now It’s Sleep Training

You can train to run a marathon. You can train yourself to recognize Chopin. But can you train yourself to sleep (or train yourself not to have insomnia)?

Michael Schwartz, creator of the Sleep On Cue iPhone app, says yes.

Michael Schwartz, creator of the Sleep On Cue iPhone app, says yes.

Sleep training “appears to work via conditioning,” Schwartz said in a recent email exchange. “People ‘learn’ the act of falling asleep. I have found it to be helpful for those who struggle to fall asleep initially and/or struggle to return to sleep during the night.”

But why do insomniacs need to learn to sleep when for most people sleep is effortless?

Intensive Sleep Retraining

The idea of sleep training is based on intensive sleep retraining (ISR), an insomnia treatment originally developed by sleep researchers in Australia. It grew out of sleep studies showing that many insomniacs fall asleep more quickly and sleep longer than we think we do.

Schwartz has observed this phenomenon firsthand in his work as a registered sleep technologist in the United States.

“It seems [that insomniacs] who are taking a traditional hypnotic . . . tend to overestimate sleep time,” he says. “Then if the insomniac begins a tapering of the medication, it swings to an underestimation of sleep time.”

Unlearning and Relearning Sleep

The question of why so many insomniacs tend to underestimate sleep time has not been definitively answered. ISR proponents suggest that insomniacs’ trouble sleeping is conditioned, resulting from poor sleep habits, worry about sleep loss, and negative beliefs about sleep. Eventually we lose touch with what falling asleep actually feels like.

So the goal of treatment is to retrain insomnia sufferers in the experience of falling asleep. Proponents claim that sufficient practice (within the prescribed protocol) will make our perceptions more accurate (i.e., more in sync with objective sleep tests, which indicate we’re sleeping longer) and restore confidence in our ability to sleep.

The Challenge and the Payoff

The ISR treatment as originally prescribed is short but onerous. You spend 25 nearly sleepless hours in a sleep lab. Every 30 minutes, you get a chance to fall asleep (and if you fall asleep, you’re woken up). At the end of the 25-hour period, you’ve had lots of practice falling asleep . . . and you’re very sleep deprived.

But after the initial 25 hours the benefits of ISR are immediate. With loads of sleep pressure built up by the next night and instructions on how to proceed, insomniacs who undergo ISR have experienced improved sleep starting at Day 2. The gains continue, research has shown, for at least 6 months.

A Sleep Training App

An insomnia treatment that involves wiring patients up in a sleep lab and round-the-clock supervision by sleep technicians is very expensive (which may be the reason nobody’s doing ISR in the United States). So when a call came out to get ISR out of the lab and make it available to insomniacs at home, Schwartz went to work.

“After reading the ‘call to action’ article by the notable insomnia researchers, I began thinking about how to detect sleep onset without expensive amplified EEG recording,” Schwartz said. He came up with several ideas before landing on the idea of an iPhone app.

“My ‘ah-ha’ was to realize that a call (tone) and response (slight movement) with a smartphone might be the ticket,” Schwartz said, “and it seems to work well.” Here’s how:

  • You lie down in bed holding your iPhone. Each time the phone emits a tone, you shake it slightly.
  • If the app doesn’t detect a shake, it assumes you’re asleep and vibrates to wake you up.
  • A message then comes on the screen: “Do you think you fell asleep?” You press yes or no.
  • You’re then instructed to leave the bed for a few minutes. The phone vibrates again to indicate when to return to the bed for the next sleep trial.
  • You decide when to end each training session. The screen then displays a graph with information about your sleep ability and your awareness of your sleep.

Modified ISR

The Sleep On Cue protocol is very similar to the ISR protocol, allowing for repeated, short sleep onset opportunities with sleep–wake estimation and confirmation. But Schwartz felt he needed to make ISR more palatable for home users.

“So I decided to reduce each sleep trial time slightly after each successful sleep attempt, as well as to prompt the user to leave the bed for just a couple minutes between sleep trials,” he said. “These two features allow more sleep trials in a shorter amount of time.

“I suggest . . . that sleep training should be done around bedtime for a couple of hours following any poor night of sleep. So maybe 10 sleep trials. Put the phone down and go to sleep when done, review the summary graph in the morning.”

Testimonials on the Sleep On Cue website suggest the app has been helpful for users, including users coming off sleeping pills. According to Schwartz, tests verifying the accuracy and clinical effectiveness of a modified version of the app are under way in Australia right now.

“The best user of my app is someone who is committed to sleep training,” he said, “who can grasp the idea of ISR and how it can help.”

Sleep: Practice Makes Perfect? Maker of App Says Yes

Would you be willing to undergo nearly 24 hours of sleep deprivation if by doing so you could learn to fall asleep more quickly?

This is pretty much the bargain you make if you undergo Intensive Sleep Retraining (ISR), a treatment developed in Australia to help people with insomnia learn to fall asleep more easily. The idea behind ISR is that trouble falling asleep is mainly conditioned, involving negative beliefs about sleep, and worry about sleep loss, and poor sleep hygiene. The goal is to get rid of these impediments and make it easier to fall asleep.

A polysomnographic technologist says insomnia sufferers can achieve the same results using a new iPhone app.

How ISR Works

You spend one night in a sleep lab. There, you’re wired up with electrodes, and every 30 minutes you’re instructed to let yourself fall asleep. But you’re never allowed to sleep more than a few minutes. A lab tech comes in to wake you up and sees to it that you’re awake for the rest of the period. Then another 30-minute sleep trial begins.

The results? The few clinical trials conducted show that insomnia subjects who have undergone ISR are able to get to sleep faster and sleep longer. These gains have lasted up to 6 months.

But ISR is currently unavailable in the US. The treatment is expensive and not covered by insurance. Plus the idea of 24 hours of sleep deprivation can be off-putting. So why mention it?

A Sleep Training App

Michael Schwartz, a registered polysomnographic technologist, has developed an iPhone app that delivers sleep training in what he believes is a more palatable way. Called SleepQ, this inexpensive app is based on the principles of ISR and designed to give users repeated exposure to what it feels like to fall asleep at home.

Schwartz’s many years of work in hospital-based sleep centers have convinced him that the problem for many insomnia sufferers is not that we can’t fall asleep, but that we lose touch with what falling asleep feels like and confidence in our ability to do it. Practice with SleepQ at a time when the pressure to sleep is high—for a few hours late in the afternoon or early in the evening following any rough night of sleep, per Schwartz’s recommendation—gives users repeated exposure to what it feels like to fall asleep and helps restore confidence, he says. Like ISR, SleepQ also enables 24-hour training for people who want to do it.

How SleepQ Works

  • Lie down and relax in bed, holding your iPhone in one hand. Every time the phone emits a tone, give it a slight shake.
  • When the app no longer detects movement, it assumes you’re asleep. Then, the phone vibrates to wake you up.
  • The screen then displays this message: “Do you think you fell asleep?” Press “yes” or “no.”
  • Next, you’re instructed to leave the bed for a few minutes. The phone will vibrate to let you know when to return to bed for the next sleep trial.
  • You decide when to end each training session. The screen then displays a graph with feedback about your sleep ability and your awareness of your sleep.

How effective is SleepQ at relieving insomnia? So far, Schwartz can cite only anecdotal testimonials from patients he’s helped. But if you’re open to experimenting, $4.99 is not a lot to lose. For more information about the app, visit the SleepQ website.
