Important Information About Product Safety

This article is about the new Oura ring. You'll find more information about the first Oura ring in our About The First Oura Ring section here.

Use, Care, and Maintenance

You can wear your Oura Ring 24/7. It can be worn in the shower and sauna, when taking a bath or swimming. It's even suitable for snorkeling. 

Try to avoid wearing the ring when strength training, working with a shovel or other heavy tools, or carrying heavy objects made of metal, ceramics or stone. In addition, try to avoid wearing the ring next to other rings or objects which are made of metal, ceramics or stones, like a diamond. The Oura ring may get scratches or it can scratch softer metal jewelry or other objects in close contact with the ring, like phone covers, made of e.g. gold, silver, aluminum. Also some ceramic phone covers may get scratches, if covered with softer coating. 

Use soft cloth or hand wash with mild soap and water to clean the ring. Always remember to dry your skin under the ring after washing your hands to prevent possible skin irritation. 

Keep the ring away from children. Do not leave the ring exposed to heat, such as in a vehicle or in the sun. Do not puncture the ring or its battery.

The ring material is titanium. Like with all rings made of metals such as silver, gold or steel, be careful when handling batteries when you’re wearing the ring. In some rare cases where both the cathode and the anode of a battery touch the ring, there is a risk of battery short circuit, similar to normal metal rings without electronics in them.

What if the ring gets stuck in my finger?

Finger size can vary depending on the time of the day, and sometimes it may be difficult to remove the ring from your finger. In case the ring gets stuck:

  • Use cold water and gentle soap to wet your finger, and slowly twist the ring to remove it.
  • Hold your hand up above your heart until the blood pressure gets lower, and then try the removal.
  • In case of emergency, cut the ring with a ring cutter from the palm side of the finger, from the ring’s thinnest point. In other words, do not cut the ridge of Balance or plain of Heritage. This prevents the battery from getting cut. 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.
