The Oura Ring & Medical Conditions

The Oura Ring is not a medical device, and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions/illnesses. The ring’s data can still provide you with valuable information regarding your sleep, activity, and recovery. Please do not make any changes to your medication, daily routines, nutrition, sleep schedule, or workouts, without first consulting your doctor or another medical professional. 

Sleep Apnea

Obstructive sleep apnea is a common medical condition that occurs when the respiratory air flow is repeatedly interrupted during sleep. Sleep apnea requires a formal diagnosis (i.e.evaluation of your medical history and a physical exam) from a professional healthcare provider in a hospital setting. They may also suggest a home sleep test, to monitor your sleep patterns. 

While the Oura Ring cannot be used to diagnose sleep apnea, it can provide helpful insights on the quality of your sleep. Individuals with sleep apnea may experience reduced deep and REM sleep, which may be reported as excessive awake time in the Oura app. 

In case of apnea referral to a sleep clinic is recommended, particularly if you have daytime fatigue. While Oura Ring cannot be used to diagnose sleep apnea, it's possible that Oura's data can provide valuable information to those who suffer from sleep apnea. Consistent sleep timing and positive lifestyle practices can also help ease some sleep apnea symptoms. Oura Ring can be used to create consistency and help you manage the impact of your newfound routine!


You should be able to use the Oura Ring with a pacemaker, although we cannot issue a guarantee on our product’s compatibility with implanted devices. The Oura’s EMF frequency is incredibly low, so in theory, there should be no interference with a pacemaker’s functionality. If you have any concerns, or experience any discomfort while wearing your Oura ring, we strongly suggest removing the ring until you consult your physician or other medical professional.


Persons with arrhythmia, such as atrial fibrillation, or other heart related condition, may find that some data, such as resting heart rate, heart rate variability numbers and sleep staging accuracy, can be affected. 

Raynaud’s Syndrome

Persons with Raynaud’s may find that their Oura Ring has difficulty measuring pulse signal. In these cases, we recommend wearing the ring in your index, middle, or ring fingers for the best pulse signal. 

Restless Leg Syndrome (RLS)

Persons with RLS may find that the Oura Ring records excess movement during the night as awake time. The same applies to certain other sleep movement disorders (including  sleep walking, nightmares, and rem sleep disorder behavior).

Heart Conditions

In most cases, Oura’s proprietary algorithms do a good job in showing very accurate resting heart rate and heart rate variability (HRV) readings and trends in the Oura app. 

The algorithms have been tested and verified against data measured from healthy adults. If you have a heart condition or other health issue that causes continuous or regular arrhythmia, or you’re on continuous medication that affects your cardiovascular system, the Oura app may not be able to show your full resting heart rate and HRV data. Instead, you may notice gaps in your heart rate and HRV graphs. In some cases, you might not see your heart rate and HRV data at all.
