Oura Ring validation for sleep using gold-standard sleep tests

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study collects data from the Oura Ring while participants undergo polysomnography to create a data set for product research, algorithm validation, and scientific sharing. The aim is to align wearable readings with established sleep metrics across a broad adult age range and BMI criteria. Exclusion criteria filter out high sleep apnea risk, certain medical devices, language barriers, and conditions that could affect ring wear or safety. The study is led by Ouraring Inc. with Clayton Sleep Institute as a collaborator, at the Clayton Sleep Institute Sleep Center in St. Louis, Missouri.

* Current active illness (e.g., cold, flu, bronchitis, suspected COVID-19)
* Have known allergies or previous reaction to titanium or medical-grade plastic
* Report regularly sleeping \<4 hours per night
* Restricted peripheral circulation (e.g. Raynaud's disease)
* Individuals with physical limitations or deformities or skin conditions that would preclude safely wearing up to two Oura Ring devices or reference polysomnography equipment
* Individuals that have completed overnight rotating shift-work in the past 2 weeks
* Individuals that have traveled across time-zones in the past week
* Current use (within the past month) of the following medications/classes, pending investigator decision: Stimulants (Adderall, Ritalin); Sodium oxybate; Heroin, cocaine, or methamphetamines; Non-stimulant wake promoting agents (e.g. modafinil, pitolisant, etc.); Prescription sleep medication
* Individuals employed by a company that develops or sells medical and/or fitness devices in a similar space (e.g. wearables) or are technology journalists (e.g. professional bloggers, TV, magazine, newspaper reporters, etc.)

Sleep Apnea sample Inclusion Criteria

* High risk for mild-to-severe sleep apnea, defined by at least one of the following:
* Prior clinical diagnosis of obstructive sleep apnea (OSA)
* Currently seeking or actively undergoing treatment for sleep apnea (e.g., PAP therapy, oral appliance)
* Documented apnea-hypopnea index (AHI) ≥5 events/hour from a previous sleep study
* Self-reported Habitual sleep duration of 6-9 hours
* Willing and able to comply with study requirements Exclusion criteria
* Same as for Healthy Adult sample, with the exception of the "high risk for mild-to-moderate sleep apnea) criterion
