Frequently asked questions
How accurate is the Oura Ring?
The sensors in the Oura Ring have been tested against laboratory results in multiple validation studies.
See The Pulse Blog for more on Oura in research and scientific studies.
Wearables differ in where they're worn, the sensors they use, and how they process data. For the most consistent and meaningful insights, it's best to track trends and changes over time within your Oura Ring and Oura App, rather than comparing your Oura results to those from other devices.
Can I wear my Oura Ring in pools, saunas, or ice baths?
The Oura Ring is water-resistant up to 100 meters (~330 feet), meaning that you can wear it while showering, swimming, or partaking in recreational diving (e.g. snorkeling), but we don't recommend using your ring while scuba diving or keeping it submerged underwater for over 12 hours. Chlorine will not damage it.
Oura Ring operating temperature ranges from –10–52°C / 14–125°F. You can safely wear your ring in the shower, hot tubs, saunas, ice baths, and cryotherapy tanks. However, extended exposure to extreme temperatures (below –20°C / -4°F or above 60°C / 140°F) may lead to battery damage.
What does the Oura Ring track?
Oura Ring gives a complete picture of your health, including:
- Readiness
- Sleep
- Activity
- Daytime Stress and Resilience
- Heart Health: Cardiovascular Age and Cardio Capacity (VO2 Max)
- Metabolic Health: Glucose and Meals
- Women's Health: Cycle Insights, Fertile Window, and Pregnancy Insights
Can I use Oura Ring without a subscription?
Oura Membership unlocks the full potential of the Oura App, allowing you to access detailed insights and personalized guidance. Without a membership, the Oura Ring can be used only with limited functionality.
How do I choose the right size for my Oura Ring?
We recommend you use an Oura Ring sizing kit before selecting your Oura Ring size. The kit includes plastic ring sizers corresponding to Oura Ring sizes, which differ slightly from standard ring sizes.
For accuracy, wear the sizing ring for at least 24 hours, including while sleeping, before finalizing your size. If you're between sizes, we recommend choosing the smaller size for a more secure fit.
