This feature is currently being tested and will be available for everyone in the coming weeks. 

Irregular breathing detection

Your breathing may be interrupted during the night without you having any recollection of it in the morning. Breathing irregularities during sleep are relatively common and it is not unusual for there to be a few instances over the course of the same night. However, a high frequency of breathing irregularities can be a sign of a more serious condition.

By analyzing real-time audio recording during the night, Dreem can detect a user’s level of breathing irregularities.


Dreem uses a built-in microphone in its headband that is only activated upon the detection of irregular breathing.

Audio analysis is carried out in real-time in the headband. For reasons of confidentiality, no audio recording is stored on Dreem’s servers.


Once detection has been activated for at least 5 nights, a section of your weekly Dreem report will be dedicated to breathing irregularities, expressed as a measure on a four-level scale.

Tap on the “Find out more” button to access the STOP BANG questionnaire (available here). This short questionnaire allows users to assess their risk for Obstructive Sleep Apnea (OSA).

Attention !

Dreem cannot guarantee that you do not suffer from breathing irregularities based solely on the lack of notification of such. If in any doubt, consult a medical specialist.

Your breathing irregularities as measured by Dreem may differ slightly from your CPAP measure should you use one. This discrepancy is due to the use of different detection methods.
