KEY TAKEAWAY
Orthosomnia is the pattern where chasing a perfect sleep score makes sleep worse. The score itself is not what does the damage: it changes what you believe about the night, and the behaviour that follows, above all spending longer in bed to improve the number, is what costs you sleep. Change the response before removing the device, and read weekly trends instead of single nights.
If tracking your sleep has made you sleep worse, you are describing something sleep clinicians named almost a decade ago. It is called orthosomnia, and it is not a failure of willpower or a sign that you are unusually neurotic about numbers.
The short answer is that the score is not doing the damage directly. It changes what you believe about the night, and then you change your behaviour to chase a better number, and that behaviour is what costs you sleep. What harms sleep is what you do about the number, not the number existing. That distinction matters, because it means the fix is rarely as blunt as throwing the watch in a drawer.
What is orthosomnia?
The term comes from a 2017 case series in the Journal of Clinical Sleep Medicine by Baron and colleagues, who described three patients arriving at a sleep clinic convinced by their trackers that they had a sleep disorder. The authors borrowed the shape of the word from orthorexia: a perfectionist pursuit of ideal sleep that ends up doing harm.
The detail that matters most is what those patients did next. All three responded to a poor score by spending longer in bed, trying to bank more of the sleep the device said they were missing. Extending time in bed is close to the opposite of what insomnia treatment asks for, and it tends to fragment sleep further. One patient had a full overnight sleep study showing normal deep sleep and a normal arousal index, and still asked why her tracker said she was sleeping badly. Another routinely opened sentences with the observation that his clinician would not like this, but his device had told him otherwise.
It is worth saying plainly that orthosomnia is a descriptive label from a case series, not a formal diagnosis. Nobody is going to be diagnosed with it. It is a name for a pattern, and the pattern is real.
Can a score really make you sleep worse?
There is a controlled experiment on this, and it is the most useful thing in the whole literature. Gavriloff and colleagues gave 63 people with insomnia disorder feedback on a watch that looked like ordinary device output, except the feedback was fabricated. Half were told their sleep efficiency had been good, half were told it had been poor, regardless of how they had actually slept.
The group told they slept badly reported worse alertness and more sleepiness and fatigue across the day, with moderate to large effect sizes. On objective psychomotor vigilance testing, the two groups were indistinguishable. The feedback changed how people felt all day without changing how they actually performed. The number was writing the story of the day before the day had happened.
A sleep read you cannot fail
FitWoody scores your night against your own patterns and your own sleep goal rather than a target set for somebody else, so one night stops looking like a verdict. 7-day free trial of Plus.

Is it the tracker, or the worrying?
Mostly the worrying, which is better news than it sounds. When researchers in Bergen built and validated a scale to measure orthosomnia in 2025, across a sample of 473 adults, the trait that emerged correlated most strongly with obsessive-compulsive symptoms, dysfunctional beliefs about sleep, sleep effort and perfectionism. Insomnia symptoms themselves correlated only modestly. The authors noted, with some understatement, that sleep tracking turned out to be rather tangentially related to the construct.
Sleep effort is the mechanism underneath all of this, and it has its own literature. A 2024 scoping review covering 43 empirical studies found that higher sleep effort went with worse insomnia severity, more pre-sleep arousal and a wider gap between how people slept and how they thought they slept. In treatment studies, a single point higher on the sleep effort scale predicted a 1.32 times greater likelihood of insomnia. Trying is precisely the thing sleep does not respond to.
So a tracker is a trigger, not a cause. It hands a perfectionist a nightly scoreboard for something that only works when you stop supervising it.
What should you do if this is already happening?
Start with the behaviour, not the device. The single most valuable change is to stop adjusting your time in bed in response to a score. If the number was bad, get up at your usual time anyway. Extra hours lying there chasing a total is the specific move that made things worse for all three of Baron's patients, and it is the one worth removing first.
Then change when you look. Checking the score before you have had any experience of your own day lets the number set the tone, which is the exact effect the sham feedback study produced on purpose. Look in the evening, or once a week, or not at all on days you already feel fine.
Third, read trends and stop reading nights. A single night is mostly noise, both physiologically and in the measurement itself, and wrist devices are far better at detecting sleep than wakefulness. If you want a metric to actually work on, regularity is the one with the best evidence behind it and the least room for obsessive scoring, which is the argument in why consistent timing beats total duration.
Taking the watch off is a valid option, and it is rarely the first one. If the three changes above do not settle it within a few weeks, then yes, stop tracking sleep for a month. Nothing is lost, and knowing whether the anxiety follows the device out of the room is genuinely informative.
Does knowing how the score works help?
It helps more than people expect, because most of the fear comes from treating an estimate as a verdict. A sleep score is a model built from movement and heart rate, weighted by choices its designers made, and how those numbers are actually assembled is less authoritative than the confident single digit suggests. The same goes for the mornings when the score and your body disagree: feeling fine after a bad score is common, and your own read is not the unreliable one by default.
This is why FitWoody scores sleep against your own patterns and your own sleep goal rather than against a target somebody else should hit, and why it reports where you sit relative to your own range. A number you cannot fail is much harder to become anxious about.
When is it worth talking to a doctor?
We do not diagnose anything, and this is a good place to say so. If you have had trouble sleeping three or more nights a week for over three months, if you are exhausted during the day regardless of what the tracker says, or if anyone has noticed you stop breathing or gasp during the night, that is a conversation for a clinician rather than an app. Cognitive behavioural therapy for insomnia is the first-line treatment for chronic insomnia, and it works on exactly the sleep effort and belief patterns described above.
Being unsettled by a number is not a character flaw. It is what happens when something involuntary gets a public score, and it is fixable without giving up on knowing anything about your own body.
Frequently asked questions
Is orthosomnia a real diagnosis?
No. It is a descriptive term introduced in a 2017 case series in the Journal of Clinical Sleep Medicine for a pattern clinicians kept seeing: a perfectionist pursuit of ideal sleep, driven by tracker data, that ends up making sleep worse. It is not in any diagnostic manual, and nobody will be formally diagnosed with it.
Should I stop wearing my sleep tracker?
Not as a first step. The changes with the most evidence behind them are behavioural: stop extending your time in bed in response to a bad score, stop checking the score first thing in the morning, and read weekly trends rather than individual nights. If a few weeks of that does not settle things, taking a month off tracking is a reasonable next move.
Can a sleep score make you feel worse even when you slept fine?
Yes, and it has been tested directly. In a study of 63 people with insomnia disorder given deliberately fabricated feedback, those told they had slept badly reported more sleepiness and worse alertness across the day, while objective vigilance testing showed no difference between the two groups.
