Oura Ring Scientific Sleep Test (Review)
HTML-код
- Опубликовано: 8 сен 2024
- How accurately can the Oura Ring predict your sleep 💤? That is the question I answer in this video.
For 18 nights I wore both the Oura Ring and a professional scientific sleep EEG to bed 🛌. The professional device basically has more than a dozen electrodes attached to my head and face and tracks my brain waves. By wearing this device and the Oura Ring to bed 🛌, I tested how well the Oura is able to predict the different sleep stages.

Is there a better alternative
Fitbit has a higher accuracy, but you say the oura ring's sleep score is a very good coorelate of many other metrics? Is the same the case with Fitbit or is oura ring's slessp score somehow superior while fitbit's accuracy is superior?
This is not a review, this is a research! Brilliant. I wish you do same with Apple watch.

Excellent stuff. Would be great if you tested more of the devices you have at hand!
The most helpful review and video I’ve seen on the Oura ring and I’ve watched a lot of them. Thank you so much for taking the time to make such a scientific and high quality video. You’ve helped me and others tremendously in making an educated buying decision. Without your videos I would have been ignorantly assuming the data these trackers give are accurate.
Thanks Steve, glad I could be of help! Really appreciate the compliment! Enjoy your weekend!
We all feel this way! Thank you for your diligent efforts.
Thanks a lot for this review. You're the only one on the internet who actually put some effort into checking this device using scientific method.
Thanks Daniel! Appreciate the compliment. :-) Have a great day!
the only type of review i care about. brilliant. thanks for this
I appreciate that! Thanks Syrone!
Totally inaccurate you need to compare for a population of people not one person.
@@jmax4238 well yeah you're not wrong . In theory testing it on a population or at the very least a sample would be better. Haha but unless u will be carrying it out I think this one will suffice
@@jmax4238 the fact that it only gets 60% accuracy on a specific user is probably quite telling. Only two things I can think of that could go wrong is (1) a faulty device or (2) oversized ring. Only in case of the latter can the low correlation with a professional device be justified. Any other reason mean ms that the device does not work as advertised.
It would be sooo nice if you test Honor Band 5. It costs only 30$, but Honor/Huawei claims that TruSleep (sleep algorithm) was developed in conjunction with Harvard Medical School's CBD Center and has high prediction accuracy.
Hi PDVJAM, great idea! Thanks for commenting. I hope to run a bunch of tests once the corona measures are relaxed at some point. If I do, I'll be sure to include the Honer Band :-D
Very thorough. Helped see past the marketing in the other reviews and saved me $300. Now to find something else to track sleep...
Oura is the best possible wearable device unless you strap something to your skull to measure brain waves
Thank you for taking the time to do this. I'll stick with my fitbit. You saved me a fortune. 👌
Glad I could help Roxana! Thanks for commenting an have a great day!
data is absolutely beautiful and I love looking at scientifically accurate data with commercial devices that say its "the most accurate on the market". I appreciate the data and your work, thank you.
Thanks so much for the compliment demirkafa! Really appreciate it :-D . Have a great day!
I’m a sleep medicine neurologist. My view on these kinds of sleep trackers as they exist now is they can be useful in helping people recognize their current sleep habits/patterns and modify their behavior. In order to sleep well it helps to set the conditions for good sleep, so adjusting your behavior accordingly is often an important part of treating sleep problems. As long as you don’t worry too much about the accuracy of specific sleep stages, you can get a general sense of what time you slept, how much you slept, and when you woke up. That’s actually quite useful as a clinician.
Thanks for sharing your research, I would have thought these machines were originally tested vs actual sleep machines and then tweaked to perform as they are actually advertised. These companies should hire you to help them build better products!
Thank you. For me, I find temperature and HRV data as more important than sleep stages.
Makes a lot of sense Jaraj! I made videos about those too, and these seem to do pretty well :-) . If you are interested: ruclips.net/video/VIfvRzP79Bs/видео.html and ruclips.net/video/AK47cav1i28/видео.html . Have a great day!
I was looking at the Oura Ring as something different from the Fit Bit Charge 2 he currently has. This video along with a previous video about the Fit Bit Charge 4 (actually 3) helped me to decide on the Fit Bit Charge 4. After all 71.6% accuracy is better than 51% when sleep is your primary concern.
I was considering both this device and the fitbit charge 4. Thank you for your honest review. You are very rare on RUclips. I'm now your newest subscriber.
Hi ohplezz! Thanks so much! I try to be as honest as possible :-) . Have a great day!
@Maximilian Beer it's me again, different account. I was asking whether u actually went for the fitbit, cause it is also not totally precise, I guess.
Best review video on Oura ring so far! Clear scientific data input in making this video and the ideas are presented in a simple way. It really helps me to decide whether I should purchase the Oura ring or notb, when the accuracy of sleep monitoring would be the major reason to make the decision (especially when I've considering other device for tracking sleep cycles likes Fitbit, but with much cheaper price). What I've learned that it's almost impossible to get a high accuracy (at this stage of technological advancement) despite Oura ring has always claimed to be the best sleep tracker so far when compared to other. But when you have devoted enough time to track the whole trend with the possible factors affecting your sleep quality recorded, one would benefit from these devices and explore the best environment and setting for achieving their best good night sleep. Anyway Great Content and I wish everyone here a good night sleep.
Thanks so much, and thanks for your input! Indeed the general trends over time are the most important for a lot of people. Have a great day Tommy!
i've read from reddit that the accuracy of the oura ring improves after 2 weeks of use, I recommend u use it for a longer time like 1-2 months and do an update video!
Hi KC, thanks for your comment! If you check at his timepoint of the video: ruclips.net/video/atWcp6FmnbE/видео.html , you will notice I tracked it over a period of 5-6 months. I normally get a sleep EEG only on Monday evenings, so hopefully the Oura should have adjusted to me :-) . But good comment, I did not know
I am wearing the ring for two weeks, I enjoy it a lot, it llos great and the interface quite intuitive. I don't need absolute accuracy of sleep tracking, since I sleep relatively well. I like the activity goal setup which considers past day and night, age etc. At the moment it asks me normally less than I actually do - and this is a good motivation, exceeding instead of falling short.
Great to hear and thanks for commenting! For sure, sometimes accountability and just knowing the rough numbers really help! The Oura ring definitely has some good features, which I discuss in these videos: ruclips.net/video/AK47cav1i28/видео.html and ruclips.net/video/VIfvRzP79Bs/видео.html . Thanks so much for sharing your thoughts, and have a great day!
Excellent review! If you keep doing the same for wider range of technologies your channel will explode. Congrats!
Hi Rodrigo! Thanks so much, that's the plan! ;-)
This guy always smiling while talking giving me good vibes
Thanks so much. I assumed my REM levels would be higher, and I guess they are. I also have a Withings under-the-mattress sleep tracker and am pretty sure the Oura ring is more accurate. As you say, Oura's software can be improved.
Hi Roger! Yes, the Oura ring is likely more accurate. I used the previous version of the Withings mat, and made a review about it in case you are interested: ruclips.net/video/J_n5VoLuLq4/видео.html
Stumbled across your vodeos while trying to figure out a best way to monitor sleep, sleep apnea, snoring and wishfully help me through alerts or some such. Love how you using a scientific approach to understanding device accuracy.
I know you like the Fitbit but am wondering if you have a best recommendation for devices at home or at least some ideas or useful links.
Considering getting the Charge 4 but so many seem to be having quality issues with it.
Thanks!
Hi John, thanks for your comment and the compliment! :-) Specifically for your range of problems a FitBit would be OK, though of course it would not detect everything and cannot send alerts (as far as I know).Of the top of my head I cannot think of any out of the box system that alert you when those problems occur, though I am not as versed in the world of consumer devices as others are. I'll think about it a bit more, and if I come up with anything, I'll let you know. Have a great day! Cheers, Rob
great breakdown, thanks.
I was getting swept away with the hipster marketing a paid youtube reviews, but you brought me back to my senses.
Dodged a bullet with this ring I think.. a sleep tracking device which thinks you're awake when you're fast asleep? Great job Oura 😆
This is an absolute *treasure* for those of us trying to sort through the noise of all the health experts and influencers doing clandestine paid advertisements for these types of devices.
Your findings also match what I'd heard from a friend who examined this device with polysomnography.
Hopefully Oura can improve their software to match their promises / marketing. Given that it doesn't work as a fitness tracker since infrared LEDs deal poorly with motion, it really should perform significantly *better* than fitness trackers at sleep-tracking , not significantly worse! Especially if it costs 2-3x more.
This really helps protect consumers from unscrupulous companies, health pundits, and influencers who take advantage of the fact that consumers lack EEGs (much less PSG) to validate claims. Thank you Rob.
Another amazing video. Thankyou so much. What I like about you is that you are totally genuine. Not sponsored at all. Which means we can trust your data. Love it. Thankyou. Hopefully you will get loads more subscribers.
Thanks Annette! Very nice to get these positive comments :-D! Enjoy your day!
This is amazing! Great work, and thank you so much for sharing. Goes without saying, but this is the most methodical and useful review on the Oura ring that I've seen.
Thanks so much Amar!!
Best scientific review I've seen. Thank you for making a simple to understand yet also very factual based video. I'm looking to invest in a sleep tracker and this was extremely helpful. I also enjoyed the How I Met Your Mother clips. Could you make a WHOOP band review? Thanks again
Hi Jonathan! Thanks for the compliment, and glad i could be of help. Really good to hear that people enjoy my videos. Have a great day!
I’d like to see an accuracy test done with the the Whoop band too!
@@JCampbellDK , hopefully I can get that done at some point indeed :-). Thanks for commenting!
Same thing, interested how whoop strap will perform. Thanks 👍
@@pavelefimkov1805 Thanks Pavel, good to know that multiple people are interested! Have a great day!
Fantastic video, really informative. Seeing as you think it's a software problem rather than a hardware problem, I'd personally be very interested to see a follow up ~2 years on. I'd also be interested in hearing what alternative sleep trackers you'd recommend instead.
I was stressing a lot about having 5-6 awake spikes for some nights and this video just confirms my assumptions that most of them are just not true
Best appraisal video I have seen. Thanks a lot, I’m going to stick with my Fitbit.
Glad it was helpful! Thanks Kieran!
I literally just purchased one. And then I saw this review. I am hoping the software improves but it is better than what I have now which isn't much. Thank you for the science and review!
Hope you enjoy it! There are many benefits to the Oura ring too, I discuss them in these videos: ruclips.net/video/VIfvRzP79Bs/видео.html and ruclips.net/video/AK47cav1i28/видео.html . Have a great day!
awesome video. Was thinking about going from Fitbit to Oura Ring... for $300, I expected a lot more accuracy. Thank you.
Glad I could help! If you are specifically interested in sleep stages indeed the Oura does not add much. However, over time I have come to appreciate that the temperature and heart rate variability (HRV) measurements can also add some value. Something to consider. In a few days (Sunday hopefully) I'll release a video about HRV and the Oura ring, in case you are interested. Thanks for the compliment!
Best review of an oura ring... I was planning to buy it 'cause I want to track myself and my sleep. Thanks!
Hi Ruben, Thanks so much. I also made two other videos about the Oura ring if you're interested: ruclips.net/video/AK47cav1i28/видео.html and ruclips.net/video/VIfvRzP79Bs/видео.html
Relevant and trustworthy review. Thank you. I do consider buying the oura ring. Following this, I will surely wait until it is more accurate concerning the sleep measurement function.
Glad it was helpful Kenneth! Have a Great day :-D
Omg i never post any comment you made me write one now rest of the youtubers... pls listen Pay attention....this is research analysis and "Review" I am amazed you took the time to do it .....pls suggest a good hrv monitor ....which will not make me sell my organs ....we truly appreciate your hardwork and really thankful
Man this is the real thing. Real example data shown exactly as it is. Thanks so much for making your videos!
ty.. I'll save my money. It need's at least 15% more accuracy
Pls make same test with whoop :)
Thx for great work !!!
Thanks Martin, if I ever have the opportunity, I will. Thanks for commenting :-)!
Your scientific comparisons are pure gold! Thank you!
I need better sleep accuracy, this what I want to focus on. Illl have to wait for them to improve this before I buy one.
fantastic review!!!
Thanks so much for the compliment David! Have a great day!
Please do this with the whoop!!
I appreciate the time you put into this. Will be looking for another once Oura Ring does a software update. If possible, a new Fitbit Sense/Oura Ring comparison would be nice. Maybe they will send you a complimentary one for evaluation.
Hi Darryl. Thanks so much! I am definitely looking into the FitBit Sense. Maybe in a few years when my Channel is bigger they will send me one :-D . Have a great day!!
Best review on oura sleep tracking. I have both oura and Fitbit and this definitely helps 🙏
Thanks Dongenaro! So you also noticed the video on the FitBit I made? Have a great day!
@@TheQuantifiedScientist great just watched it! Good to know its quite accurate. Keep m coming :)
@@dongenaro Thanks! Will do :-D
I was definitely looking into one of those rings so thank you!
Glad I could help Jessica!
I just bought one. Since I don’t have access to a “professional” monitor I’ll have to use this....still better info than no info, imo
@@christineritchie8014 Indeed better than nothing, and it is accurate at looking at your total time asleep. Also, the non-sleep measurements might be of interest. Hope you enjoy it!
Oh shit Iv just bought one 😱 should be delivered tomorrow. Have I just wasted my money 😱😱
@@AdamSmith-nk1kc Hi Adam. I would suggest you just try it out, and see if you like it. It also tracks other things like HRV and your temperature, which it appears to be better at: ruclips.net/video/VIfvRzP79Bs/видео.html . Let us know what you think of it in the end!
Dude - thank yo so much for posting this. I've seen a lot of quack doctors and non scientists raving about how its accurate/reliable and suggesting it could be an alternative to conventional polysomnography. Don't get me wrong, it seems super cool and I think the technology and direction they're taking wearables may very well be the future of health as we know it.
That said, it bothers me a little when people start to compare "tech disrupting devices" to validated/rigorously tested medical equipment. Seeing someone actually test it head to head is the only review I can trust.
Awesome channel! Nothing else on RUclips like this
Thanks for the compliment Jane! Hope I can continue to make videos that are fun and/or useful for you :-D
I REALLY appreciate the hard work you put into this video! Great job and thank you. I was about to purchase the oura ring for sleep tracking specifically, but I'm glad I found your video first.
I would love to hear your thoughts on what the most cost-effective sleep measurement tool is.
Awesome! Thank you!
So, FitBits seem to do pretty OK, and are not extremely expensive. So you could give one of those a go (the Fitbit Charge series is what I've mostly tested). If you are purely interested in sleep, and want to spend more money, the Dreem 2 Headband seems like a good choice, though my experience with this is limited to scientific literature.
Hope this helped! Let me know if you have any questions!
Incredible review - thank you, keep this up. All good content rises to the top with enough time
Much appreciated August! Thanks for the wonderful compliment! Have a great day
WHOA ! your fit bits got better accurate rating over the $300 aura !
Sure did Matt! Though the Oura ring does have some other cool features, for instance: ruclips.net/video/AK47cav1i28/видео.html and ruclips.net/video/VIfvRzP79Bs/видео.html
@@TheQuantifiedScientist got yah! i saw the nba thing and was like oh shit Oura must be the shit . i better bite the bullet and buy it . but my main concern was sleep, and i had no idea they were using it for early covid detection . that makes sense tho!
the other fit bands didnt have HRV?
i thought this was super standard in fit bits etc and how they monitor sleep as well
@@mattduncan5500 Hi Matt. Thanks for your comments! For the longest time I wore the Fitbit Charge 2, and now the Charge 4, and as far as I know, neither measures HRV. Though for instance Garmin does have it as an option I believe (i anyone knows better, please correct me). However, I would also like to see a validation of the accuracy before buying these for that purpose, because measuring HRV on the wrist can be tricky. Hope this helps!
@@mattduncan5500 I think it is becoming more and more common, but not all trackers have it, and the accuracy will vary :-) . But if anyone has good experiences with other devices, please let us know! Have a great day!
My experience with the Oura ring is that it does not distinguish between awake time during the night and sleep. It got the awake portion confused with light, deep and REM sleep alike.I was surprised and disappointed, my understanding was that Oura boasts 98% accuracy when compared with a professional sleep device.
Love the video and the information it presents, and you are a very charming man. However, I believe what you are describing as a "prediction" (referring to anticipating a future event) is really a "description" (referring to an event in the past, i.e., how you slept on a given day).
This was a phenomenal analysis! Thank you!
really liked this video. please do same comparison with Honor Band 5 (it also has pulse oximeter)
Thanks Mohsin! I will do this the next time I use a professional EEG :-). Have a great day!
Subscribed, liked, commented. This is definately the way these kinds of devices should be reviewed! I also enjoyed the fitness tracking reviews that you did. Most reviews are from tech sites and wellness sites, and really they only review the form factor and ease of use of devices, instead of how well they actually work in their objective. I was interested in the Withings Steel HR and your HR comments gave me a wake up call there.
Thanks for posting. I think this tipped the scales against my getting the Oura ring, although still considering.
Hi Robert, thanks for your comment. Good luck with making the decision!
I was wondering if the oura ring accuracy may have been influenced by its battery charge. If TheQuantifiedScientist sees this, pls respond, would love to learn.
Keep up the great video
I have used the second generation oura ring for about one year and a half. I agree with your findings. It is not possible to predict sleep stages with an accelerometer and PPG. However I do find the Oura ring reasonably accurate in predicting sleep duration (total time in bed). This metric has helped me keep a consistent sleep schedule. I do not know the accuracy of the HRV metric, However I do find the rate at which resting heart rate drops to be useful in determining how quickly I relax during the initial stages of sleep. Thank you for the video. RL
Nice review!
As a little improvement, you might think about normalizing confusion matrix by rows(since rows are assumed as ground truth) so that it would be easier to read for a general audience.
Hi Andrii! Thanks, I will definitely consider it for the next video. Thanks so much, really helpful to get this type of feedback!
Hi Andrii! I Used your suggestion in my latest video: ruclips.net/video/lWPxpdUjLBI/видео.html . Thanks!!
Thanks! Nice to see such an in depth review.
Hi Pieter, thanks for your comment! Glad the video was helpful!
Thank you for your dedication to develop this great work of analysis! I returned my Oura Ring after feeling it didn’t fit well in my overall routines, specially because it’s not a dedicated sports tracker. I do believe a green light sensor for moments of training would be a great advantage even at the expense of battery life, there are many solutions to that issue. I knew it wasn’t very good at predicting sleep stages according to public research and so I decided to buy the new Withings Sleep Analyser. Let’s se how it performs!
Hi Andre, thanks for your comment. I am interested in the withings sleep analyzer as well. I did use the old Withings Aura System for a long time. I actually have data on that one.
The Quantified Scientist just got the results from the first night! I’m looking forward to keep using it and try to find a program and/or app that allows me to have a more in depth read of the measures tracked as the HealMatte app is too focused on “scores” rather than specific values.
The Quantified Scientist I’m a bit sad for having returned the Oura as it provided HRV and temperature fluctuations but for 300€... I don’t know.
@@andreduarte7206 Yeah, I get it. I'll try to check if HRV and temperature provide any predictive value in another video.
The Quantified Scientist that would be such an amazing information. HRV may be a bit of a current narrative without much data behind.
Awesome video. Thanks for sharing
Thanks for the compliment Mknox242! Thanks for commenting and have a great day!
I hope you keep going until we find a proper sleep tracking device that’s minimal and portable. I’d like to see at least a 90+ percent accuracy before considering investing in one
Hi Jake, hopefully we'll get there at some point. But with something on your arm or finger that will probably be tricky, just by the limited amount fo measurements it can do. So we will probably need something attached to the head. thanks for commenting and have a great day!
Thank you for making this video
Glad it was helpful!
Fantastic video. Would be great if you could investigate the sleep accuracy of the whoop strap.
Thanks for your comment TheEisst! I will do my best to get my hands on one. Have a great day!
Just found your channel. I love it! Please keep making videos.
Thank you! Will do!
You're awesome, I'm an industrial designer designing new devices and this helps alooot. Thanks :D
I was considering the Oura ring... I currently use a Whoop and I am not happy with it. I would love if you did the same with a Whoop, perhaps I would find some reason to stick with it. Loved the video! Thanks.
Hi! I am hoping to do a video on the Whoop strap at some point :-). I actually wanted to look into some scientific literature on it, but it is locked behind a pay-wall unfortunately. Hopefully I can provide you with more info about the Whoop strap soon! Have a great day and thanks for commenting!
Excellent visual aids and translations!!
Hmmm I stick with my Fitbit Versa. Another great video.
Thank you for making it. I am sure your subscribers appreciate it since you still have your day time job. Lol!
Hi Fujihobo, thanks for your comment! Hope you are enjoying the Versa!
Goed bezig ! As an engineer I truely appreciate this awesome content. Being a lousy sleeper with a busy job, I look forward to finding out how the 3rd party Apple Watch apps stack up in terms of sleep tracking.
Thanks for the great content.
This video was amazing, thank you for your deep analysis and confusion matrix. You're incredible.
Thanks for the compliment Kastan! Thanks for commenting and have a great day!
@@TheQuantifiedScientist My friend runs a startup for sleep improvement (thru experimentation with the Oura ring). Probably something you'd be really into bioloopsleep.com
@@KastanDay Thanks Kastan, I'll have a look :-) !
I own one and think it's really cool. I hope they update the firmware and app to become more accurate.
Great video. I only watched it today on Nov 4,2021 so I wonder if the algorithm has improved. I have a Oura version 2 which I recently purchased so they are sending me the new version 3. I am 65 and am finding the ring useful for the readiness score. It is too early to tell, but I hope to use this to understand better how to optimize my daily exercise. One of the problems as we age is that recovery takes longer, so very easy to overtrain or push too hard. I am hoping the ring will help me avoid this better.
Saludos! I'm thinking to buy a sleep tracker. And looking for a reliable review (not just have they felt but how is the accuracy) I came to yours, it is amazing. +1 sub and I will recommend your channel to friends.
Hi Angel! Thanks so much for the compliment! happy to help, and stay tuned for more videos!
Thanks for saying the truth
You are very welcome!
This video is so helpful, you have no idea!
just found your channel. Love it! Subscribed :)
Thanks! Welcome aboard!
Finally someone did this comparison! Thank you!
This channel was a nice find. I like how demonstrative and thorough your format is good job :) . Considering the theme of sleep what are your thoughts on wim hof breathing?
Awesome, thank you! So, I have actually done a study on the Wim Hof technique pubmed.ncbi.nlm.nih.gov/32290188/ . Now, this is just my personal opinion, but: I think there are effects of the breathing techniques that he uses for sure. However, I am not sure if you cannot reach similar results in other ways of exercise and breathing, and if the effects are overstated. Objectively, I can just say that we saw changes in the metabolism of people in our experiment, however what that means for the consequences of the breathing technique and how specific the effects are to his technique I am not sure. Though i must admit I am naturally very skeptic to these kinds of things, so I just try to state the facts as they are :-) . Have a great day!
A couple of things to consider: first, the visual at 6 minutes says it all. I’d much rather wear the ring than wear the helmet with 500 wires coming from it. Second, the accuracy is less important than the consistency. Oura is not a measurement device. It is a tracker. It is meant to help you see the delta between your best and worst. For that it doesn’t need a super high degree of accuracy. Finally, Oura results take about a month to stabilize as it has to learn your baseline. Did you wear the ring for a month prior to running your test? I have an Oura and I really like it.
Like the professional approach, thanks!
Thanks for watching!
Awesome experiment and super interesting video, well done
Thanks so much! Have a great day!
Great study! Great Review! Great speaker! Thank you! It would be great if you would make a similar study of go2sleep ring, which is getting very popular in the last time
Great suggestion!
Thank you for your video. I just bought the Oura ring and the Dreem Band 2 and I'm thinking of returning the Oura ring because of all I've heard of it's inferior accuracy.
Hi Jonny! Thanks for your comment! Happy to hear that my review was helpful. Have a great day!
Hi Jimmy, how do you like the dreem band so far?
I really appreciated this detailed review and all of the research that was done. Thx for the info!
Very cool video format! I would have needed that in march, when i was looking for a tracking device for a study project :D And I'm glad now I didn't spend any money on the Oura ring or the Withings pad.
In the end I decided on the Healbe Gobe 2 Smart Band, which in my opinion cannot track correct REM phases (they always look too modeled and there were always more REM phases than cycles per night), but apart from that It was a very good choice for overall health tracking, as the electrical bioimpedance sensor offers far more options than optical sensors (calorie intake, hydration and sweat-based stress / emotional tension). There is now already the successor, the GoBe 3, which should offer even better measurement results and a larger range of functions, in case you are interested to test this as well ;)
Surprised to bring some humor into this video. That was awesome hahaha
Glad you enjoyed it!
Excellent! Really scientific attitude to the problem. Love it!
Oh man, so glad I stumbled upon your channel! I'd love to see you test other wearables like Whoop and Garmin. Thanks again for doing this -subscribed!
R R thanks for your compliment! Welcome aboard ;-) !
@@TheQuantifiedScientist Hey Rob... whats your opinion on the Dreem 2 headband?
@@miketoner76 I haven't studied it in detail yet, but based on this study: www.biorxiv.org/content/10.1101/662734v1 , it seems to do quite well. (Though I did not check who funded it and I think it has not been peer reviewed yet.)
thank you very much! excellent the information you provide in your videos.
Another alternative that is shown to be variable is the dreem 2 device but it is too expensive (€ 400)
Fitbit charge 2 is enough for me. greetings and waiting for you to release new videos!
Thanks German! Yes, I am also currently using the Charge 2 as my main device, but I will be testing the Charge 4 in more detail now. Have a great day!
So roughly 60% accurate. As opposed to not tracking which is 0% accurate. & how much does a professional sleep tracking device cost? I like the honest data. It’s very useful. But, I think the real question here is if the Oura Ring can be a useful tool? I’ve seen comparisons showing it to be more accurate & useful than Fitbit or Whoop. I’ve also seen The data from Oura be useful in providing ideas for sleep improvement. I think this video may muddy the water between accuracy & usefulness. Thoughts? I’m curious what they have planned for the future, as well. Disclaimer: I don’t own any of these devices
Hi! Good point 😄In my experience when it comes to sleep tracking, fitbit performs best, closely followed by Whoop and then Oura at some distance. Now, as to usefulness: the Oura ring measures many things very well, and some of the scores it provides in the morning are related to real world mental and physical performance the next day. I think fitbit still lags behind in this, and has put some of it behind a paywall. So it really depends on youur goals. If you want to know your sleep stages, choose fitbit; if you want actionable advice, choose Oura. I discuss some of this in more recent videos . Have a great day!
Best oura review video out there! I have mild to moderate sleep apnea and would like to use a device to help me track my sleep and maintain a sleep diary. Would you recommend a fit bit 4 or other device for best available tracking?
Thanks for the compliment! Depends a bit on your budget and exact goals. If you just want to know what time you went to bed and woke up, and potentially find out something about your sleep apnea with the oxygen saturation sensor, the FitBit Charge 4 will work fine. If you want to invest more money in something that can track sleep even better (but is also more cumbersome to wear) the Dreem 2 headband would be great as well, but it is much more expensive. Not sure if this helps, but let me know.
The Quantified Scientist thanks, yes this is helpful. I want to use a device to accurately detect my initial time to fall asleep and my awakenings and time that I am awake during each of these awakenings in the middle of the night. Would the fit bit work for this?
@@onlineservices2050 Time of falling asleep and time of waking up would be very well detected. Awakenings are a bit more tricky, but I think to get a general impression of nights with more or less awake time it would work pretty well. (Based on what I have seen so far).
Hilarious, and helpful. Not hugely surprised, though I still like my Oura because I'm not into fitness and stuff on my wrists to ever use a Fitbit, and I've found it quite helpful for sleep.
Well done!! Ive wore many eeg for my epilepsy and they arent comfortable.
I was thinking of swaping the fitbit versa for the oura ring for reading my heart rate in sleep and it looks like although the fitbit isnt as comfortable the oura ring is less reliable. Thank you very much :)
Hi Rob
Awesome video .... thanks for putting in the effort to objectively track the data and professionally summarize the results.
I've been using Oura for almost a year. Over that time, I've also noticed that my REM sleep times are consistently low and the awake times are consistently high. It was very interesting to see that your study vs EEG confirms this.
I was especially struck by your comment that you believe this is more to do with software than hardware ... can you expand on this?
Hi David. Glad it was helpful! Thanks for your comment :-). I would think that the Oura ring has at least as much data to work with as the FitBit, they measure mostly similar things, and the Oura even has some extra data. The main difference is the position where it is worn, finger vs arm, however I suspect this should not be a major difference. The data quality of the Oura ring also seems pretty good. So, if they have similar data (and data quality), they should be able to have similar prediction accuracy. The fact that they don't makes me think it is mainly an algorithmic problem Does that make sense?
Aha! You've already answered my question my friend! Many thanks :)
Very helpful. Thank you.
You are welcome! Have a great day!
Great video coming from someone who knows their stuff rather than a random dude with a tight t-shirt commenting with no knowledge of science. I’ve been using the Whoop strap for six months and doubting the accuracy. Would be great if you could do some proper testing with that tracker
Hi Mark, thanks for commenting and the compliment! If I get the opportunity, I definitely will, several people have mentioned the Whoop strap actually, so it seems to be quite popular. I had not heard of it, but it might also be regional, maybe more popular in the US than in Europe? Hopefully I'll get to test it! Have a great day
The Quantified Scientist Definitely more a US based product in the popularity states. They have some links to sleep studies describing how accurate it is compared to other trackers. Looking forward to that video from you in the future. Keep up the great work
Your video’s fantastic. Nicely structured and amazing flow with accurate details.
PS : I think it was minor but in confusion matrix you included gold standard on left when it is normally up. Reason I picked it up is because our tutor used to torture us saying “god in always on top” 😂😂😂. Like I said, minor and on fitbit video it was appropriately on top
Always love your videos. I'd have two quesions!
1) Is "REM sleep" lighter than "light sleep"? I'm asking this because it's always displayed as the upper one.
2) Which sleep tracking device would you recommend? (The smallest, the better - i.e. a smartwatch is too big)
thanks for your work :)
Hi Rodas!
Thanks so much for the compliment!
(1) I guess most scientists would not necessarily say that REM sleep is lighter than light sleep per se. I suspect it is mostly displayed on top since sleep is often divided into REM vs non-REM (all the other stages) sleep. This is partly historical as far as I know/expect, and partly because of the way our sleep cycles are structured. The comment by "
György Dr. Báthori " on this video also goes into that: "The REM phase also called paradox sleeping. This mean that in REM sleep the muscle tone is the lowest and we are almost paralized. So based on the motion detectors this is the "deepest" sleep stage. In contrast the heart rate is more slower and slower as our sleep changes from light sleep to deep sleep, but in REM phase the the heart rate jumps up. Therefore based on the heart rate the REM phase is the "lighest" sleep. "
(2) Well, I would recommend the Dreem 2 headband, but that is quite large. I would recommend the FitBit Charge series second. It is still a watch, but quite small. Third I would recommend the Oura ring. I would not recommend a sleep mat that goes under the mattress for now.
Have a great day!!
Cheers,
Rob
