Dreem 2 Headband vs Science (sleep test; long version)
HTML-код
- Опубликовано: 15 авг 2024
- How accurately can the Dreem 2 Headband predict your sleep 💤? That is the question I answer in this video. I also made shorter version of this video: • Dreem 2 Headband vs Sc...
A scientific paper was just released to the scientific community where they compared the Dreem 2 Headband to a professional EEG device🛌. The professional device basically has more than a dozen electrodes attached to your head and face and tracks brain waves. Here I summarize the results from the paper.

YES! Im glad you made this video. Breaking down the research paper in common language is great!
Thanks Shervin!
This is exactly what I’ve been looking for - scientific evaluation of accuracy of commercially available sleep trackers. BRAVO! Awesome no bullshit content. Thank you very much. Please continue to bring us more sleep related content :)
Hi Stepan! Thanks so much for the compliment!
@@TheQuantifiedScientist thank you so much for sharing all valuable informations. I subbed and binged on your materials. Best regards
You understand things so thoroughly, and communicate so clearly -- I guess it's all part of being a good scientist, but I just really appreciate you and your videos, specifically. :D
Thanks so much for the compliment and the comment! Have a great day!
Thank you so much! Please continue reviewing sleep trackers.
Thanks for the compliment Iván! Will do, thanks for commenting and have a great day!
since the DREEM is no longer going to be sold to end users, can you test other devices like the MUSE 2?
are there any alternatives to the DREEM?
they sold their distributer rights to 3rd party. Australia division Resmed is selling it, you can order online. I am getting one, as I live in Sydney Australia
Thanks for this review 👍
It could be nice if you can do the same about the Muse S too 😜
Yeah pls do Muse S review too!
They've stopped making the Dreem 2. Any chance you can do a review on the Muse S or similar basic lead EEG device?
Rob, thanks so much again for the great work. Have you considered reviewing the Muse products? Cheers, Phil
Hi Rob- Fantastic videos! I am a cancer researcher but am interested in tracking my sleep with a consumer EEG device. Would you recommend ZMAX or Dreem2 for this? Also, it seems if you purchase Dreem2 in Canada or Europe it has slow wave stimulation capabilities- any thoughts on this? All the best- A. Rob MacLeod
Dreem 2 is available from distributor now, you can get it easily in Australia - Resmed in Australia got the distributor ship and selling it.
thank you for making these videos! definitely subscribed
Hy!
How about Philips SmartSleep Deep Sleep Headband?
Amazing video!! Thank you from Brazil!
i thoroughly enjoyed this video. thank you for making it. subscribed.
Thanks for the sub Asyush!
Any chance you could do a study on the Muse-S?
Great vid! How does the muse 2 stack up to the dreem 2? Dreem 2 is now unavailable right?
what about muse s (gen2) ??
Great video, thanks breaking this down
Thanks for the review! It looks promising
Sehr gelungenes Intro!
Thanks Daniel! Appreciate it :-D
Thank you.
Welcome David!
I have insomnia but i don't know how can i sleep with those wires and other things on me, how they don't invent something which will not disturb sleep? I also have problem with overactive bladder so how then to go to toilet if i am connected on polysomnography device?
Hi Rob,
Looks like a very nice device. Wondering how it stacks up against an emfit. Perhaps you can do a test of that some day.
And I am looking at getting one.
Would it be cool if there was a device that records a video of the dreams you have at night?
Not available anywhere. Why?
Wow!. January 2021. They told me they dont know when dreem 2 will be avialable, it is sold out wolrdwide. It is a shame. I hope the company is not out of business because I really like to have one.
I found some in Australia Resmed are selling it.
Hallo. Ich habe heute eine gebrauchte Headband gekauft, aber ich kann nirgendswo ein aplication dafür finden . Kann jemand bitte mich weiter helfen??? Dankeschön
The correlation between Dreem 2 and the Lab for sleep stages is very low, less accuracy than guessing?
The Dreem 2 is not available anymore, and therefore disqualified for many applications.
The Muse S could be an alternative.
The Muse app allows sleep tracking, but it is not very satisfying. To write down values from the app, or only look at graphs on the app is very limited.
Fortunately, the Mind Monitor app from Computer Scientist James Clutterbock can solve this problem. The app is excellent, and we can get all the desired data. But the Mind Monitor has no sleep tracking.
But there is Sleep: An Open-Source Python Software for Visualization, Analysis, and Staging of Sleep Data. I should be possible to feed the Mind Monitor data into the Sleep software and get a professional setup in that way. A scientific review about this would be highly desirable.
Maybe this could be a dumb question, but why these confusion matrices never sum 100% for rows or columns (for this video I would expect that rows total must be 100%, for another one that you compared Withings Sleep Analyzer vs EEG I would expect that columns must sum 100%)?
Have you compared zMax and Dreem2 head-to-head? I'd be really curious as the DREEM headbands are now only available for clinical and research studies.
Hi Rob, How are you getting the chart details that I see at 4:57 of your video. I just got a Dreem headband this week and I'm wondering how to get that detail.
Why not review the Muse Headband?
Great videos! Keep it up
Thanks a lot Luigi! I will do my best! Thanks for commenting and have a great day!!
Thank you Rob for your amazing reviews! I am very interested in tracking my sleep and have made some improvements in my sleep. I am disappointed that the Fitbit and Oura are so inaccurate. Do you know where I can get a Dreem2 anywhere in the world? I have a friend living in Stuttgart and if it is sold in Europe I would love to have one. Thanks again, you are amazing.
I bought it 2 weeks ago from an online store located in New Zealand!
@@samygold100 Awesome! I will check it out.
Will you follow this up after this times of corona with your own experiments?
Informative content. Thanks for sharing! I want to do PhD in machine learning for sleep disorders. Can I use dreem headband for that. Is it accurate enough for doing such studies. Thanks
Hi! So that is difficult for me to give advice on. I guess important things to keep in mind: (1) the dreem headband has mainly been tested on people with relatively normal sleep, so I do not know how it would act with people with sleep problems; (2) the scientific community might still be more receptive to traditional PSG devices [this might not be a good thing, but it might be the truth], (3) I guess you will always have fewer electrodes and data then with most PSGs. That being said, these Dreem bands are more comfortable, and much easier to operate. Just some random thoughts, hope they help! Have a great day!
@@TheQuantifiedScientist Thank you very much for replying I appreciate your recommendations.
@@Mohamm-ed You're welcome :-)
Thank you Rob for this high quality, informative video.
Have you thought of getting a Dreem2 device and making a study verifying sleep stages detection on your own?
A neuro-tech enthusiast has reviewed Neuroon sleep tracking device this way - got the Neuroon device, booked a night at a medical facility with PSG's and during the night had both the Neuroon and the PSG reading the biometric data. He did his own study and published it here: alxd.org/neuroon-analysis-results.html#neuroon-analysis-results
I think that a study made by just one person can be much more credible then the one done by multiple others, but involved in product development of the tested device.
Hi Karol, thanks for your comment! For sure, this is definitively in the works. The Dreem company has offered to provide me with a device, and I can test it once I can easily travel back to the sleep lab in the Netherlands I work with. I have done this in the past for the Fitbit (ruclips.net/video/UAcasFNzUl8/видео.html) and the Oura ring (ruclips.net/video/atWcp6FmnbE/видео.html). I also have data on the Withings Aura Sleepmat. Indeed, independence is very important for this :-) . I was actually thinking of trying to get a hold of several devices and testing all of them for a few nights at once. However, it will likely be September once this is really feasible for me to do, given that work and COVID-19 are making things kind of tricky at the moment.
Thanks for commenting and for the link!
@@TheQuantifiedScientist Thanks for the quick reply. Great to hear that you'd like to make your own scientific test :) I assumed that COVID might be the inhibiting factor here.
I will most definitely look into your other videos!
I'm glad I found your channel and I hope you'll keep building it - fingers crossed for new ideas, projects and quality maintenance. Sleep well :D
@@karolputra Thanks for the compliment! Have a good night too!
Thank you so much for your reviews! I heard from a sleep doctor that CBD interferes with REM sleep in a bad way. Is this true?
Hi N V, so, from what I understand using weed/marihuana can mess up your sleep cycles, similar to alcohol. So, though it might be easier to fall asleep, the quality of sleep is often lower. Now, I must say I cannot comment on CBD specifically, though I suspect there are few substances that can actually improve your sleep long-term, most are in the end detrimental if used too long. But again, I am just speculating here. What do you think?
@@TheQuantifiedScientist Thanks! I think there needs to be a study not affiliated with big pharma which pushes benzodiazepines and the medical marijuana industry for us to know. Maybe you will try it? Thanks for your help with the reviews!
@@noriginal2546 You're welcome! Maybe I will try it at some point if I can get it. Did you try, and see some effects?
@@TheQuantifiedScientist what's the legality status for CBD there? I am assuming legal? I will mail you a bottle for free in thanks for your work. I have been on CBD for over a year and it's been life changing for my anxiety issues. Still I only average 5.5 hour per night of sleep with less than 30 minutes deep sleep and it's severely impacted my life. I do work on practicing a low carb anti-inflammatory active lifestyle but it's very hard with American lifestyle. I also have autoimmune disease.
@@noriginal2546 can i contact you with personal info, just to share these. I have ben having troubles with sleeping matter such as yours. Cheers
Hi where can I buy the Dreem 2 headband ?
pretty bad rem detection. How can the Dreem 2 be used to test smart watches?
Hi! The REM sleep is actually not that bad, I just used a different type of confusion matrix which did not scale the columns in this older video. I think the main different I see between nights I score manually myself and the Dreem2 is that it does tend to "smooth" sleep stage scoring slightly. What I have seen personally is that mostly in REM segments there are sometimes short periods where the eyes are not moving, and these are still classified as REM by the Dreem2. Question is if this is wrong or right. If the eyes are not moving for 2-3 minutes in between long REM segments, was this really not part of REM. I'd have to dive into the AASM Sleep Scoring Manual to check what the current guidelines are. Overall, I think the Dreem2 is good enough to get "rough-ish" impressions of which watches are doing well and which are not😊
@@TheQuantifiedScientist Please help me find an accurate device with an app that gives a signal during rem sleep for lucid dreaming.
Good content. Please make More. i would love to be friends :3
Thanks for the nice comment!
Love all your videos and the thoroughness of your tests! Too bad this is really not a review and the paper is only a non-peer-reviewed version from the company selling it. However, since you have access to lab grade equipments & ZMax, Dreem has published the code for the actual method they called DOSED, would be very interesting to compare your own grading from ZMax vs DOSED to the EEG data recorded. github.com/Dreem-Organization/dosed/
