Orthosomnia and Sleep-Tracking Anxiety

What it is

The term comes from a 2017 clinical report in the Journal of Clinical Sleep Medicine. The authors described patients seeking treatment for self-diagnosed sleep problems such as short sleep or insomnia, based on light or restless sleep seen on their tracker. [1] They wrote that the link patients drew between tracker data and daytime tiredness could become a perfectionistic quest for ideal sleep. [2] Patients also said tracker data often felt more consistent with their experience of sleep than polysomnography or actigraphy. [1] This was a clinical observation by sleep clinicians, not a measurement of how often it happens.

The word "orthosomnia" has no single agreed definition. In 2025 researchers built the Bergen Orthosomnia Scale to measure what they describe as excessive preoccupation with sleep. [3] In their data it was linked with sleep effort, unhelpful beliefs about sleep, perfectionism, obsessive-compulsive traits and health anxiety, though correlation does not show that trackers cause these traits. [4]

How common is it?

Estimates depend heavily on how it is defined.

• In a general-population sample of 523 people, 35.8% regularly used sleep-tracking devices, and algorithm-identified orthosomnia ranged from 3.0% to 14.0% of the sample depending on how strict the cut-off was. [5] The authors caution that the study is cross-sectional and cannot show cause. [6]
• In a US survey of 897 adults, among those who already owned a sleep device, 12.3% reported sleep-related worry (orthosomnia) and 17% did not trust the data. [7]
• In a 2026 Norwegian survey of 1,002 adults, people with insomnia reported more negative effects of sleep apps, and the authors suggest it may be wise to caution patients with sleep problems about such use. [8]

These are self-reported surveys. They show that worry exists and that it clusters among people with sleep trouble, not how much harm trackers cause.

Why a tracker can make worry worse

• Scores look precise but are estimates. In a lab study, devices were much better at detecting sleep than wake. [9] See Why Sleep Trackers Disagree.
• One night is noisy and normal variation is large. See Sleep Trends vs Individual Nights.

What to do

These are general options, not treatment.

1. Choose what to track. Time in bed and wake time are usually enough.
2. Look at the data weekly, not each morning, or take the device off the bedside for a few weeks.
3. Compare with how you feel rather than with a score.
4. Keep a brief diary instead; see Sleep Diaries vs Devices.
5. If worry about sleep is affecting daytime life, speak with a clinician. Cognitive behavioral therapy for insomnia is a main non-drug approach, and the NHS notes that a GP may sometimes offer it. [10] The orthosomnia authors say tracker use should be incorporated into that therapy. [11] See CBT for Insomnia and Insomnia.

If tracking becomes compulsive in general (for example with food, weight or exercise), see Tracking Anxiety and Compulsive Measurement.

Who should be especially careful

People with insomnia, anxiety, obsessive-compulsive tendencies or health anxiety may be more likely to feel worse with constant sleep data. [8][4]
