Product Safety & Use

Learn how to safely use your Oura ring with this guide.

Use, Care, and Maintenance 

Care

- Remember to thoroughly wash and dry both your hands and your Oura Ring. 

- If it works for your hands, it works for your ring. Hand sanitizer is safe to use.

- If you're observing more stringent hand washing protocols, you can follow the same steps as you would with other jewelry and remove your ring while scrubbing your hands to give the ring a separate cleanse.

- To clean your ring, use a soft cloth or wash the ring with mild soap and water. Always remember to dry off after washing your hands to prevent skin irritation. (If you experience skin irritation/redness on your finger remove the product immediately. If symptoms persist longer than 2-3 days, while not using your Oura product, please contact a dermatologist/medical professional).

Use and Maintenance

- You can wear your Oura Ring 24/7. It's built for all-day comfort.

- The ring is water-resistant up to ~ 330 ft. (100m).

- If your skin can take the heat, then the ring can too! Hot tubs and saunas are safe.

- To prevent scratching/internal damage avoid wearing the ring when strength training, working with heavy tools or carrying heavy objects made of metal, ceramic, or stone.

- Keep the ring away from children.

- Do not leave the ring exposed to heat for extended periods.

- Do not puncture the ring or its battery.

- Be careful handling batteries when wearing your ring. In certain cases where both the cathode and the anode of a battery touch the ring, there is a risk of battery short circuit, similar to standard metallic rings.

Ring Stuck?

In the event your ring gets stuck on your finger, please heed the following suggestions.

- Use cold water and a small amount of soap, wet your finger, and slowly twist the ring to remove it.

- Hold your hand up above your heart until your blood pressure lowers, and then try to remove the ring.

In case of emergency, cut the ring with a ring cutter from the palm side of the finger- the ring’s thinnest point. This prevents the battery from being cut. Do not cut along the ridge of the Balance or in the flat plane of the Heritage.

The lithium-ion polymer battery should not have electrolyte flowing, but, in case electrolyte comes in contact with your skin or eyes, flush it out with water and seek immediate medical attention.
