1. What do I need to use the headband?

A smartphone with the Dreem app and Wi-Fi access are required to use the headband.
If you want to know more about smartphone compatibility, take a look at this support page.

2. Can I transfer my data with a cable if I don't have a Wi-Fi connection?

Unfortunately not. The data is only transferable via Wi-Fi.

3. Is it necessary to have Wi-Fi access to upload the data?

Yes. However, the headband can store up to 8 nights before being overwritten.

4. Do I need Wi-Fi to start my night?

No, you can start your night using the Dreem app on your phone or the headband’s touchpad (long touch). Wi-Fi is useful in the morning for uploading data.
If you want to know more about the touchpad’s functionalities, you can read this support page.

5. Do I need the app to start my night?

No, you can start your night by using the headband’s touchpad (long touch): the night’s parameters will be the same as the last ones you set in the app.

6. Can I schedule the beginning of the night’s recording in advance?

No, the beginning of the night cannot be scheduled in advance or started automatically/remotely.

7. Can I set the night’s parameters for a participant?

Yes, parameters (active features) can be set in the app and the participant just has to start the night (via the app or touchpad).

8. Can I skip the sleep assessment phase?

Yes. Once you have downloaded the app, let us know if you would like to skip this step and we’ll do it for you remotely. (The first 7 nights with the headband are dedicated to analyzing the user’s sleep. During this first step, the Relaxation Techniques and Pink Noise aren’t available.)

9. Can I enable/disable the active features of the headband (SIP, stimulations, etc)?

Yes, all active features are optional.

10. How can I run a study with stim/sham situations, without the participant having access to info about deep sleep stimulation (on/off)?

You can simply turn the stimulations off/on on the app and ask your participant to launch the recording by using the touchpad.
If you want to know more about the touchpad functionalities, you can read this support page.

1. Is it possible to check the quality of the signal?

You can check the signal quality by looking at the live EEG. If your subject or patient is relaxed with closed eyes, alpha rhythm should be visible. We cannot provide you with an impedance value.

2. What is the displayed channel on the live EEG in the app?

The EEG derivation displayed in the app is the one with the best signal quality.

3. What about the maximum level of sound in decibel, emitted during stimulation (as perceived by the bone conduction)?

It’s very hard to have a precise measure of the equivalent in dB of the bone conduction as compared to a sound produced by a speaker. By using sensitivity tests, it seems that the volume we use is equivalent to a perceived 40 dB sound. However, if you would like to maximize the effect, we can increase the volume.

1. What is the headband’s warranty?

Our warranty covers the Dreem headband for two years. Refurbished headbands are covered for 6 months.

2. How you’ll find to wash the headband?

We recommend using ethanol to clean the device as it’s inert for all the headband’s external components.

3. Can I buy extra pads for the headband?

Yes, you’ll find some extra pads in the box and you can buy more if needed.

1. For how long can I hold data in the headband?

The headband can hold around 80 hours before overwriting the recorded data. That means you shall be able to recover all (or most of) the data, of 8 nights without Wi-Fi (unuploaded data).

2. Can I upload the data to my phone and then synchronize them with the cloud after several days?

The headband has to be connected to Wi-Fi to enable the server to process it, and unfortunately, you cannot upload the data to your phone.

3. What format are the recordings in?

As a researcher, our special offer provides you with the raw data. The format is basically HDF5, but we can generate the EDF files on demand.

4. Is it possible to store the data on local servers?

The data is accessible on our external online viewer, and you can download and store it on your servers.

5. How secure is the data?

Personal data protection is central to our privacy policy. We ensure the confidentiality of all your personal data, including any data resulting from the use of our sites. Your personal data will never be sold, exchanged or transferred without your consent for any reason.
If you want to know more about the touchpad functionalities, you can read this support page.

6. Where are your servers located?

Data is available in multiple formats, all of which are open and can be analyzed and/or processed with the adequate tools. The unprocessed raw data is available as binary blobs. Once processed they are stored as HDF5 files and/or EDF.

Currently, recordings must go through our servers in order for them to be accessible. The storage pipeline is as follows: First, the recording is created and stored by the headband only, on its internal storage. Once the recording is over and the headband is plugged in and connected to Wi-Fi, the recording is uploaded to our servers and deleted from the headband. The raw recordings are then accessed and processed by our internal services, making them available for download afterward.
The actual storage for these records is Amazon S3. For EU users, all our servers and storage capabilities are located in an AWS region located within the EU. Data access permissions are granted only to you and certain members of our team.

1. If multiple individuals are wearing headbands, is there a way to link them all to one device controlled by the researcher, instead of each participant having the device linked to their personal phone?

We can create an administrator account for the researcher, who will be able to monitor all the headbands' data. You would just have to let us know which Dreem account (email) will be the administrator, and which Dreem accounts (email or name of headbands) we need to link.

2. Can I access data from multiple users?

Please see above.

3. What information can I get from my recordings?

The Dreem headband measures EEG, heart rate, head position and breathing rate. This raw data is processed and only aggregated metrics are displayed to the user. Indeed, on the basis of the biosignals, Dreem detects physiological patterns in real-time and computes a sleep stage classification. You can also find your hypnogram, your positionogram and the times of any stimulations.

4. Can I score the data by myself?

Yes. You can download your data and score it by yourself, using your own software.

5. Can I change the stimulation algorithm by myself?

No. Some parameters can be modified on our side, but these changes remain very rare and light.

6. Is it possible to customize the stimulation algorithm (sleep-staging, pink noise stimulating, etc…)

No. Some rare and light parameters can be modified on our side.

7. Can extra sensors be added on demand or is there a possibility to integrate them to the Dreem headband by ourselves?

It’s not possible to add extra sensors to the device. In order to synchronize your physiological or psychological measures with the EEG recordings, we recommend you use recognizable markers on the EEG such as blinking.

8. Is there an API for interacting with the Dreem headband?

No, there is no API currently.

9. What is the post process on filters?

The visualization channels that can be observed on the viewer are raw channels filtered using a band-pass filter between 0.4 Hz and 18 Hz and two notch filters at 50 Hz and 60Hz.

10. Does the headband have a GPS?

No, the headband doesn’t have GPS. But as smartphones do, Dreem can obtain the localization information in the app (in order to know the timezone), but the headband when used alone does not have any information about geolocalization.

11. Are the deep sleep stimulations (pink noise) dangerous for the brain?

The deep sleep stimulations are merely sounds, with reasonable intensity. They do not present any contraindication nor known adverse effect.

1. What about your clinical trials?

Dreem is currently running two clinical trials for its headband, one in France and one in the USA: https://clinicaltrials.gov/ct2/results?term=dreem. The Dreem Beta headband passed one clinical trial in France already.

2. What about the Dreem papers and publications?

You can find some of our scientific publications here: https://dreem.com/en/science.

1. Is the headband a medical device?

The Dreem headband is not currently considered as a medical device, but we’re working on it.

2. How can I be sure that the headband is effective?

The Dreem headband has been subject to numerous clinical trials and scientific validation, notably when testing the precision against that of polysomnography and the deep sleep stimulation (Pink Noise). What’s more, our coaching programs are based on Cognitive Behavioral Therapy, which is the reference solution recognized by the medical community. As such, these programs have real results if followed correctly.

3. Can I use the headband’s data to diagnose a patient?

Unfortunately not, because the headband is not currently considered a medical device.

4. Is the headband covered by health insurance?

No, the Dreem headband is not covered by health insurance.

5. Can I buy headbands and then rent them to my patients?

The headband is designed for individual, long-term use. Once the restructuring program is completed, it’s the ideal companion for occasional sleep check-ins and optimization when needed.

6. Can the headband be coupled with relaxation techniques (hypnosis, meditation, sophrology)?

Yes, the headband actually has audio features, including relaxation exercises designed specifically to make falling asleep easier.

7. Can the headband treat pathologies (apnea, restless leg syndrome, narcolepsy, depression etc…)?

No, the Dreem headband is not adapted to the detection of these sleep pathologies.

8. How can I be sure that the headband won’t have a negative impact on my patients’ health?

The Dreem headband only transmits sound to users. Wi-Fi and Bluetooth waves are not active during the night.

9. Can I make money by recommending Dreem to my patients?

No, for ethical reasons, it’s forbidden to profit from recommending Dreem to patients.

10. Can the headband be coupled with sleeping pills or phytotherapy?

Generally speaking, yes. There are no contraindications. What’s more, we strongly remind users to never stop a prescribed treatment when starting to use the Dreem headband.

11. I’m a doctor, can I access the Dreem Viewer?

No, the viewer and access to raw data are uniquely for research and scientific studies.

12. Is there a headband that just analyzes sleep without the programs or active audio features?

No, the headband has always been solved with the possibility to use the programs and audio features. Whether someone chooses to use a program or the audio features is then their own choice.
