Insomnia test: do you have insomnia, and what can a night recording add?

Most people who search for an insomnia test are really asking "do I have insomnia?" They want a yes or a no, and a number to hold on to. The answer from the field is less satisfying and more useful. There is no scan, no blood marker and no gadget that can say yes. What there is: a short questionnaire, a conversation, a way of ruling out lookalikes, and the surprising fact that many people with insomnia sleep more than they feel they do.

This page explains how insomnia is actually assessed, where an app or a tracker helps and where it misleads, and how to walk into an appointment with something better than "I just can't sleep". If you only want the checklist, skip to the one-week plan further down.

Insomnia test: no scan, no marker, just what you report

A 2026 review in Nature Reviews Disease Primers states it bluntly: diagnosis relies on self-report, as a biomarker for the disorder has not yet been established. The same review gives the prevalence of insomnia disorder in adults as 10 to 16%, and describes two sets of symptoms that belong together. Night-time symptoms are difficulty starting sleep, difficulty maintaining it and early morning awakenings. Daytime symptoms are fatigue, perceived problems with thinking and concentration, and mood disturbances. An earlier review, from 2015, describes the disorder as dissatisfaction with sleep duration or quality plus difficulties initiating or maintaining sleep, along with substantial distress and impairment of daytime functioning.

In other words, a bad night is not insomnia and neither is a short night. Insomnia is the persistent combination of a sleep complaint and a daytime cost. Formal criteria add a minimum frequency and duration, which your doctor will ask about. The classification manual that sleep medicine uses, the third edition of the International Classification of Sleep Disorders, lists insomnia as one of seven major categories, next to sleep-related breathing disorders, hypersomnolence, circadian rhythm disorders, movement disorders and parasomnias. That matters, because several of those neighbours can produce the same complaint.

Insomnia in one line

Doctors define insomnia in one line as a persistent problem getting to sleep, staying asleep or sleeping long enough despite the chance to, with consequences by day that you feel. If the daytime half is missing, you may simply be someone who sleeps a little, which is a different situation.

Signs of insomnia, at night and by day

The signs of insomnia fall into the two groups above, and it helps to ask yourself about both. Symptoms of insomnia at night: taking a long time to fall asleep, waking and not getting back to sleep, waking well before you meant to. Symptoms of insomnia by day: tiredness or flatness, a foggy head, irritability or a lower mood. Many people also describe a kind of dread of bedtime, which belongs to the picture but is not one of the cited criteria.

Insomnia types: three ways the night goes wrong

The night-time symptoms give three rough insomnia types. Sleep-onset insomnia is trouble getting to sleep. Sleep maintenance insomnia is trouble staying asleep: waking in the night and lying there. Early morning awakening is waking hours before the alarm and not going back. Many people have more than one. Chronic insomnia is the persistent version, and persistent insomnia has been linked to adverse long-term outcomes including worse quality of life and physical and psychological illness.

When insomnia symptoms point somewhere else

Many sleep disorder insomnia symptoms overlap with conditions that need different handling. Waking repeatedly in the night and feeling unrefreshed is also what sleep apnea can feel like. A strong urge to move the legs in the evening is restless legs. A body clock that runs late looks like trouble falling asleep at a normal hour. This is the case for a conversation rather than a self-test, and for the related pages on waking at 3am, sleep apnea without snoring and restless legs.

The Insomnia Severity Index: the questionnaire people actually mean

When an online insomnia test shows you a score out of 28, it is usually a version of the Insomnia Severity Index (ISI). Its seven questions cover how hard it is to fall asleep, stay asleep and avoid waking too early, plus how satisfied you are, how much the problem gets in the way of your day, how noticeable it is to others and how worried it makes you.

What has been measured about it is more modest than a lot of web pages imply. A study by its research group examined 959 people drawn from the community and 183 people evaluated for insomnia treatment, plus 62 controls without insomnia. The ISI showed excellent internal consistency (Cronbach alpha of 0.90 and 0.91), and its scores correlated with fatigue, quality of life, anxiety and depression. A cut-off score of 10 was optimal for detecting insomnia cases in the community sample, with 86.1% sensitivity and 87.7% specificity. In the treatment sample, a drop of 8.4 points was associated with moderate improvement after treatment.

That makes it a screening tool. At that line, about 14 in 100 people who have insomnia would be missed, and about 12 in 100 people who do not have it would be flagged. The number is a reason to talk to somebody, not a diagnosis. Insomnia testing in a clinic goes beyond it: history, sleep diary, medicines, mood, and a look for other sleep disorders.

What a sleep tracker can and cannot say about insomnia

The most important result for anyone who owns a tracker comes from a laboratory study of seven consumer sleep-tracking devices, tested against polysomnography in 34 healthy young adults over three nights, one of them deliberately disrupted. Every device was good at detecting sleep: epoch-by-epoch sensitivity was at least 0.93. They were poor at the reverse. Specificity, the ability to correctly call wake, ranged from 0.18 to 0.54, sleep stage comparisons were mixed, and devices did worse on nights with poorer sleep.

Insomnia is largely about being awake when you want to be asleep. A tool that is excellent at saying "asleep" and mediocre at saying "awake" is therefore a weak insomnia detector. The same study calls for testing the devices in other populations and settings, and its volunteers were healthy young adults, not people with sleep trouble.

There is a second problem, which clinicians have named orthosomnia: patients seeking treatment for self-diagnosed sleep problems based on light or restless sleep seen on their tracker, and developing a perfectionistic quest for ideal sleep. The authors of that report describe a tracker's data often feeling more consistent with the patient's experience than validated techniques. Checking the score every morning and going to bed anxious about it can feed the very problem it was meant to measure, which is the worry behind the term.

Paradoxical insomnia: when the night was better than it felt

The best-known twist in this field is misperception. A review in Psychological Bulletin describes the puzzling finding that many people with insomnia overestimate how long it takes to fall asleep and underestimate how long they sleep, compared with objective measures. The tendency is ubiquitous, although not universal. Of thirteen possible explanations, the best supported were misperceiving sleep as wake, worry, and brief awakenings. The term paradoxical insomnia is used in clinical classification for cases where the complaint is far larger than the measurements, and the term itself is not from the review.

Two things follow, and both are easy to get wrong. A recording that shows several hours of sleep does not mean the complaint is imaginary, because the misperception is a recognised part of insomnia and the distress is real. And a tracker score cannot settle it either way, because trackers are weakest at wake. The sensible use of a recording is to compare it with a diary, not to win an argument with your own experience.

Insomnia is a sign of what? The conditions it overlaps with

The usual follow-up question, what is insomnia a symptom of, has no single answer. The 2015 review says insomnia can be the chief complaint but more often co-occurs with other medical or psychiatric disorders, such as pain and depression. The 2026 review adds that insomnia disorder is itself an independent risk factor for other mental disorders and physical diseases. So the arrow can point either way.

Insomnia or depression?

Insomnia or depression is a question without a clean answer, and it is often both. Insomnia is an independent risk factor for other mental disorders, as the 2026 review puts it, and disturbed sleep is also part of how depression shows up, so a clinician asks about mood either way. That is the main reason this page does not offer a self-scoring shortcut: whatever score you get, the next sentence is "tell somebody about the mood as well".

Breathing is the other big overlap. In a clinic cohort of 2,401 people with suspected obstructive sleep apnea, 49.5% had insomnia by questionnaire and 16.9% had both moderate-to-severe apnea and insomnia. The authors cite 30 to 50% of people with apnea as having comorbid insomnia and argue for screening for both. That is a sleep-clinic sample, not the general population, but it explains why a snoring partner and a restless night belong in the same conversation.

How to know if you have insomnia: one week of information

Whether you have insomnia is a clinical question. Knowing enough to take it to a clinician has a practical answer: gather a week of facts.

1. Answer the seven ISI questions once and note the total. In the community study a score of 10 or more was the best line, and everybody scoring below it can still have a problem worth discussing.
2. Keep a plain diary for 7 to 14 nights: when you went to bed, how long you think it took to fall asleep, how often you woke, when you got up, how the day felt.
3. If you want an extra view, record a few nights. Compare what you wrote with what the recording shows: sound, movement, time stamps of wake-ups. How to record yourself sleeping explains the set-up.
4. Add the sleepiness check if the days are the problem. The Epworth Sleepiness Scale takes a minute.
5. Bring all of it to a doctor. A diary, two scores and a few recorded nights make a better first appointment than a general impression.

Treatment is not this page's subject. The 2026 review notes that clinical guidelines recommend cognitive behavioural therapy for insomnia as the first-line treatment, with digital versions available, and that most sleep medicines are recommended for short-term use only. What you do with that is a decision for you and your doctor.

What a recorded night can show

A recording answers different questions than a questionnaire, and it is worth being clear about which.

A recording cannot tell you that you have insomnia. It can show whether the 3 a.m. wake-up came with a snore or a gasp, whether the hours you call lost were quiet, whether a partner's noise is part of it, and whether the same hour repeats night after night. It can also protect you from the wrong conclusion, in either direction: a night that sounds long and peaceful may sit next to a complaint that is still real, and a night full of stirring may explain why you are tired when the diary says eight hours.

Which tool answers which question: a short decision guide

• "Do I have insomnia?" A clinician, with the ISI score and your diary as input. No device settles this.
• "Is something else hiding behind the bad nights?" A few recorded nights can show snoring, pauses or a noisy room, which is worth bringing to the appointment.
• "Was I really awake as long as it felt?" Compare the diary with the recording, remembering that misperception is a recognised part of insomnia and not a sign you are making it up.
• "Is the deep-sleep number on my screen meaningful?" Treat it lightly. Wake detection is the weak spot of consumer devices.

We build a sleep tracker, so the easy move would be to say a recording tells you whether you have insomnia. It does not, and no app can. SleepTrace marks snoring, coughing and talking on a timeline with timestamps and estimates sleep stages from sound and movement. Those stage estimates are in the same class as the devices in the laboratory comparison above, so read a wake estimate lightly. The audio is the useful part: when you stirred, what the room did, and a record over weeks you can show somebody. If the question is mostly about tracking, how to track sleep without a wearable goes through the options, and tired but can't sleep covers the feeling this page started from.
