Q: You did a survey that suggests that clinicians are less keen on these devices than consumers. Conor Heneghan of Fitbit/Google also mentioned a study using the Fitbit Charge and a SleepLife portal. The patients were very engaged but only one physician (out of 49) logged into the portal to look at the data.
A: Our survey of sleep professionals (which we need to publish) showed that they were wary of the data. They found it frustrating in some ways because it took time out of the clinical encounter.
Some of them said that parents are putting trackers on their children and then catastrophizing their children’s sleep.
Q: Is there such a thing as an ideal hypnogram or does it vary by individual?
A: I would say that it depends on a lot of things. If you think about a hypnogram from a sleep study, the patient is not sleeping in their home environment, and it’s only one night. There’s a range of what would be considered normal, and it’s related to your sex and your age.
One night is not going to be sufficient to characterize your percentage in this or that sleep stage. Our patients come in saying, “I’m not getting enough REM.” But there isn’t a sleep disorder called lack of REM; there’s no treatment for that. It’s probably pretty normal for them or maybe they’re taking medications that suppress their REM, such as antidepressants.
The tech world is very interested to sense REM properly and to display it. But on the treatment side of things, there’s not much that we do with that data. We’re more interested in the consolidation of their sleep, the duration of their sleep, breathing-related sleep disorders, those sorts of things.
Q: Is there any reason to be concerned about the amount of REM sleep in terms of outcomes? We know that poor sleep can lead to bad cardiovascular outcomes, but has any of that correlated to sleep stage?
A: There are studies where they’ve experimentally deprived people of certain stages of sleep, but they’re not very useful in the real world. We’re looking at sleep holistically: Do you have a good sleep pattern? Any breathing-related sleep disorders? Insomnia? We don’t treat sleep by the stage.
Q: Any concern that people who are focused on a device may be ignoring the basic tenets of good sleep hygiene?
A: If people are doing things that are obviously bad for their sleep, like working too late, not exercising enough, sleeping in on weekends to compensate for being up late during the week, or probably the biggest thing contributing to insomnia – stress. A device itself won’t fix those things but it could show you the evidence.
If somebody really has a sleep disorder, then sleep hygiene alone is probably not going to be enough. They’re going to need to engage in a more extensive program to improve their sleep, such as cognitive-behavioral therapy for insomnia.
Q: Is there anything else you want to mention?
A: I don’t want to leave with a reputation of being against sleep trackers. I think they are a great opportunity for people to get excited about and learn about their sleep and try to improve it. We have a lot to learn about what people want from their data and how we can use that data to improve people’s sleep.
As providers, we can engage with our patients – sleep is an automatic process, but improving sleep takes some effort. Buying a device is not going to automatically make you sleep better. It takes work to establish a better sleep pattern; it may require some cognitive-behavioral therapy or treating a sleep disorder. That takes some work.
