Orthosomnia: When the Sleep Tracker Is the Thing Keeping You Awake

You woke up feeling reasonably fine. Then you checked the ring, saw 61, and by the time you reached the kitchen you had reinterpreted the morning: actually you are exhausted, actually today is going to be difficult, actually you should not have had that drink on Tuesday.

Or the reverse, which is stranger. You feel wrecked, the app says 91, and you spend the day quietly suspicious of your own body.

And then the part nobody admits to: lying in the dark, aware you are not asleep, thinking about how the tracker is recording that you are not asleep, which is not helping you get to sleep.

That last one has a name. Sleep clinicians coined it in 2017, and it is orthosomnia.

The term, and the case series behind it

Kelly Baron and colleagues published a paper in the Journal of Clinical Sleep Medicine in 2017 titled "Orthosomnia: Are Some Patients Taking the Quantified Self Too Far?" It described patients arriving at a sleep clinic with complaints driven substantially by their tracker data.

The name follows the pattern of orthorexia, the unhealthy fixation on healthy eating. Ortho meaning correct, somnia meaning sleep: an unhealthy preoccupation with achieving perfect sleep.

The patients in the series shared a pattern. They were pursuing an ideal defined by a consumer device. They treated the device's output as more authoritative than how they felt. Some were spending longer in bed to improve their numbers, which is close to the worst possible response, because time in bed awake is exactly what maintains insomnia. And in some cases, the clinical assessment found their sleep was fine and the tracker was the problem.

It is a small case series, not a prevalence study, and nobody knows how common this is. What is known is that the paper landed in 2017, when wearable sleep tracking was a fraction of what it is now.

Why the tracker is less accurate than it looks

This is the part that changes how you read your data.

Consumer sleep trackers do not measure sleep. They measure movement, heart rate, heart rate variability, and sometimes temperature and blood oxygen. Then an algorithm infers sleep stages from those signals.

Polysomnography, the clinical standard, measures brain activity directly via EEG, along with eye movement and muscle tone. That is how sleep stages are actually defined: the definition of REM is electrophysiological, and your wrist cannot see it.

Validation studies comparing consumer devices against polysomnography find a consistent pattern. Devices are reasonably good at distinguishing sleep from wake overall, and substantially less reliable at staging it. Deep sleep and REM estimates in particular can diverge considerably from the lab. A known specific weakness is that lying still while awake tends to be scored as sleep, which means the number can flatter exactly the night you spent motionless and miserable.

There is also no agreed definition of a sleep score. Each manufacturer has its own proprietary composite, weighted by their own choices, not calibrated against clinical outcomes. Devices worn by the same person on the same night do not agree with each other, or with a sleep lab, on everything: when seven consumer trackers were tested at once against polysomnography, their accuracy varied by device and by measure (Chinoy et al., 2021). A score is a vendor's opinion, presented with two significant figures.

The loop

The mechanism is the same one behind health anxiety generally, and behind the panic cycle.

1. You look at the score. Attention goes onto sleep as a performance.
2. Sleep is one of the very few things that gets worse when you try. Effort produces arousal; arousal is incompatible with sleep onset.
3. Now you are awake and monitoring your own wakefulness, which is more arousing still.
4. The next night carries anticipatory anxiety about repeating it.
5. The tracker records the worse night and hands you a worse number, which confirms that there is a problem.

This is not a new loop. It is precisely the worry-and-monitoring loop that cognitive models of chronic insomnia describe (Harvey, 2002), and the tracker functions as an amplifier: a nightly, quantified, seemingly objective source of evidence that your sleep is failing.

Worth saying clearly, because the loop is what CBT for insomnia treats and it is treatable. See why you wake up at 3am for the physiology of the specific case, and scrolling instead of sleeping for the other common version of the same problem.

The interoception angle

There is a deeper thing happening than anxiety about a number.

Interoception is your sense of your own internal state. Sleep tracking systematically teaches you to override it, and the training is repeated every morning: you feel one thing, the device says another, and you learn to defer to the device.

Over months this can genuinely degrade your confidence in your own reading. People report no longer knowing whether they are tired without checking. That is a real cost and it is not on any product page, because the entire proposition is that the device knows better than you do.

For most metrics that is a defensible claim. For "am I tired", the subjective reading is not a rough proxy for the real answer. It is much closer to being the answer.

What to do

Consider not tracking. The most effective intervention for orthosomnia is the obvious one. If your sleep is fine and the score is what is bothering you, the score is the problem. Take the ring off for two weeks and see what happens to your sleep and your mood.

If you keep it, look at trends only. Weekly and monthly averages are where the data has some validity. A single night's score is noise presented as a verdict, and the stage breakdown is the least reliable part.

Never look at it before you have decided how you feel. If you must check, check in the afternoon. This preserves the reading you would otherwise overwrite.

Do not extend time in bed to chase a number. This is the specific behaviour the original paper flagged and it makes insomnia worse. Sleep restriction, which is the counterintuitive core of CBT for insomnia, goes the other way.

Take feeling seriously over scoring. If you feel rested and the app says otherwise, you are rested. If you feel wrecked and the app says 91, you are wrecked. The device is inferring from your wrist; you have direct access. One exception: if the device flags low blood oxygen, or someone you sleep beside says you snore loudly, gasp or stop breathing, see a doctor, because that can be sleep apnea, and feeling rested does not rule it out.

Get an actual assessment if it persists. If you have had significant sleep problems for more than a few weeks, that is a conversation with a doctor about CBT for insomnia, which has better evidence than any wearable. The tracker is not diagnostic and its data is not a substitute for an assessment.

Why this keeps happening

Not because tracker companies are villains. The devices are impressive engineering and the data is genuinely interesting.

It happens because a number invites a target, and a target invites effort, and sleep is the one domain where effort is counterproductive. The product category is built on a feedback loop that works well for step counts and training load and works against you here.

It is also a specific instance of the general problem with quantified self tools: a metric you can see becomes the thing you optimise, whether or not the metric is the thing you actually wanted. You wanted to feel rested. You got a score, and scores are much easier to care about than feelings.

Frequently asked questions

What is orthosomnia? A preoccupation with achieving perfect sleep as defined by a tracking device, to the point where the pursuit itself worsens sleep. Named by Baron and colleagues in 2017. It is a descriptive term, not a formal diagnosis in the DSM-5 or ICD-11.

Are sleep trackers accurate? Reasonably good at total sleep versus wake, considerably less reliable at staging. Deep and REM estimates in particular diverge from polysomnography. Lying still while awake is a known failure case, and no two manufacturers compute a sleep score the same way.

Should I stop using my sleep tracker? If checking the score affects your mood or your sleep, yes, at least for a trial period. If you find the trend data interesting and it does not change how you feel about your night, keeping it is fine.

Can a sleep tracker cause insomnia? It can contribute by amplifying the arousal-and-monitoring loop that maintains chronic insomnia, and by encouraging longer time in bed. Whether it causes insomnia in someone who had none is not established.

What is the actual treatment for insomnia? CBT for insomnia is first-line and better supported than any device or supplement. It includes stimulus control and sleep restriction, both of which are counterintuitive and both of which work. Ask a doctor rather than an app.
