Sleep-Tracking Devices Have Limits. Experts Want Users to Know What They Are
Experts highlight that sleep trackers infer sleep from heart rate and movement, with the U.S. market valued at $5 billion in 2023 and expected to double by 2030.
- Experts warn that millions of people who use phone apps and wearable sleep trackers should understand their limitations and use the data responsibly, as trackers infer sleep rather than measure it directly.
- Recording movement and heart rate, these devices infer sleep states while algorithms used by major brands detect sleep accurately but estimate stages less precisely than in-lab polysomnography.
- Users report Kate Stoye quit alcohol and avoided late meals after her Oura Ring linked those habits to poorer sleep, while Daniel Forger recommends trackers to fine-tune routines even without major disorders.
- Some patients present with anxiety over scores called 'orthosomnia,' which led Mai Barreneche to stop wearing her ring years ago, while Dr. Chantale Branson advises focusing on sleep hygiene and clinician consultation, not scores.
- Market data show the U.S. sleep-tracking devices market generated about $5 billion in 2023, and researchers exploring clinical applications of wearables see potential for infection and mood-related detection.
