Oura & Medical Conditions

The Oura Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions/illnesses. 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

Sleep Apnea is a common medical condition that occurs when the respiratory airflow is interrupted during sleep.

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.


You should be able to use the Oura ring with a pacemaker. Oura’s EMF frequency is relatively low. There should be no interference with a pacemaker’s functionality. If you experience discomfort while wearing your ring, we suggest removing the ring and consulting your physician or another medical professional. Oura cannot issue a guarantee on our products' compatibility with implanted devices. 


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. 

Blood Circulation Issues

Persons that have Raynaud’s or other blood circulation issues in fingers may find that their Oura Ring has difficulty measuring their 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.

Heart Conditions

In most cases, Oura’s proprietary algorithms do a sound job of showing accurate resting heart rate and heart rate variability (HRV) readings and trends.

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 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.
