Sum up of the clinical trials done by Dreem with Hôtel-Dieu

We are proud to announce the release of the results from our last clinical trial, conducted within the French hospital, Hôtel Dieu. It is currently being reviewed by scientific experts. During the past 3 years, we have worked on research, development, and enhancement of sleep by using the Dreem Band.

These clinical trial results were obtained using the beta version of the Dreem headband. The beta version of Dreem was launched in March 2016. The new version of the headband was announced for pre-order earlier this year, in June. It is based on the same technology and seeks to improve the quality of deep sleep. This study focuses on the classification of sleep phases (realized via EEG measurement) and deep sleep stimulations (through sound frequency between 500 and 1.000 Hertz, typically called “pink noise”).

Frontiersin published the official results of this clinical trials done by Dreem with the French laboratory Hôtel-Dieu. The goal of this article is to give you a quick sum up of these results.

The clinical trial with Hôtel Dieu

It was divided into two parts:

– The 1st part of the study, conducted on 20 subjects, demonstrated the results of the Dreem headband when compared to data collected via polysomnography. This randomized study was realized double-blind with crossed protocols for 60 nights.

– The 2nd part, an observational pilot study realized at home on 90 subjects evaluated the functioning of the headband Dreem. Some cases were excluded from the analysis of this study: people who slept less than 3 hours, people with deep sleep higher than 3 hours and people with recordings lower than 5 hours.


The results demonstrate that the Dreem headband has similar acquisition quality than the polysomnography. In real time (specificity 0. 90, sensitivity 0. 70), the Dreem headband is also able to synchronize the acoustic stimulations accurately during the deep sleep phase. Furthermore, the study shows that the repeated hearing of stimulations (10 nights) still produces the same effect on subjects. It means that the subjects’ brain does not get used to the repeated hearing stimulations.

This clinical trial confirms the promise of Dreem, which is to identify and measure the various sleep phases with precision and improve the quality of deep sleep by the process of sound stimulation.
