@@TheQuantifiedScientist idk if that is a compliment. The price is garbage, like the ring. I want source code for that price. The website looks like it’s hiding things. Is the ring Bluetooth? That would suck and be really energy hungry. The dock could be Bluetooth but the ring should be NFC.
Thanks so much Alex! I hope to be testing the Apple Watch once the new generation is released. It should have sleep tracking as a standard feature! Thanks for commenting and have a great day!
Hey Rob! Thank"s for a truly great video. I am a PhD candidate in Belgrade working on HRV and EEG and I am interested if you could tell me what app did you use to record HRV from Polar chest strap during the night? It would really help my research!
get a pro grade microphone and crank the science part up to 11 and become a professional tech reviewer. you definitely have an edge on most other people I know.
Agree,, but remember,, that there's possibly just as many people who are not as tech savvy. I think your sound was great the way it was. Your clear and easy to understand, thanks for your reviews. Just subscribed 😃👍
Incredible review! I enjoyed the more objective perspective of the oura ring! Especially combined with your video on the accuracy of the oura ring’s sleep stage prediction. Thanks for your work!
Great review! I was looking at the Oura ring and the Polar but decided to go with heartmath’s inner balance. It should be arriving in a few days. Apparently they have been around for some time and have a huge list of professional clients. It would be pretty cool to see how it holds out in your lab. Will you be comparing other biofeedback devices such as the Sensate Pebble as well as brain wave scanners like muse 2 or muse S with other similar devices? Wonderful channel. I feel as if it’s the only one I can trust on the subject.
Hi Michael! I had not heard of a lot of these yet :-D. I'll check them out on the internet and see if I can acquire some over time! Thanks so much for the suggestions !
Great video again! I'm looking forward to see how oura ring hrv correlates with your score of feeling sick. I did something similar in the past, after taking vaccine for yellow fever and the impact was felted almost a month after taking it.
Yes, for sure, great idea! I plan to see how HRV associates with all kinds of measurements I have been doing, including my notion of feeling sick! Thanks for the support, and I'll try to make content valuable for you and others :-). Have a great day!
Liked and subscribed! Wearing the sizing ring now anxiously awaiting delivery of my Heritage Stealth. Hoping to understand my sleep patterns better and lose 20 pesky pounds. The positivity of your review will surely help to that end, cheers!
Really awesome video. I really appreciated the well contructed video that answered my question about the accuracy worries i had about the oura. Good job dude. liked and subscribed.
Ich komme aus Deutschland und finde deine Videos echt toll, weil man mal ein paar Informationen über die Genauigkeit der Produkte kriegt z. B. wollte ich mir einen Oura Ring 2 kaufen habe das aber dann wegen den Videos nicht gemacht da mir die Genauigkeit für diesen preis viel zu niedrig ist, würde mich echt freuen, wenn du mal die Genauigkeit des Xiaomi Band 4 oder 5 oder 3 testen könntest da dieses Gerät im Vergleich zum Oura Ring oder Fitbit zwischen 3 bis 10 mal günstiger ist. Ich danke dir für diese Videos und mach weiter damit falls du Zeit hast, es gibt echt viel Nachfrage für solche genauen und präzisen Videos wie deine!
Vielen Dank für das Kompliment! Ich habe möglicherweise einige Daten zum Mi Band 3, die ich überprüfen muss. Das Problem ist, dass das Abrufen der Rohdaten für diese Geräte manchmal schwierig ist. Aber ich habe definitiv auch vor, einige der "billigeren" Geräte zu überprüfen. Ich habe die Schrittzählung für das Mi Band 3 überprüft: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--T2xvWq5e3o.html . Have a great day!
Hi Rob (awesome name ;-) ) ! I am planning to look into it, though I don't know the timeline yet. Recently a scientific paper came out about the Whoop strap and its sleep prediction, unfortunately I cannot access it, since it is locked behind a pay-wall. Hopefully I can get to it at some point and also test it myself. Stay tuned!
@@TheQuantifiedScientist I found the article via Sci-Hub. The lead author's position at the uni is sponsored by Whoop. Like the oura ring, looks like it also fails to record data reliably, but I will leave interpretation and validation of results to you as I'm just an interested layman.
Awesome suggestion! I was looking into that at the moment actually. I already made a similar video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MPDQ1Tt3y14.html. Is this what you meant? Have a great day!
Hi! I plan to make some videos about the Whoop strap! However, the next videos I will first focus on the Apple Watch and the Fitbit Sense :-) . Stay tuned!
Dr Great video. Now one question is most of Smart watches which has ECG measuring function only pdetects Heart Rate variability and also for this, the user has to put one of his Finger on top. Of smart watches or on top. Electrode to close the cycle and get a ECG/ Heart rate variability on demand. Ie user has to do manually each time to get Heart rate variability and ECG But on Oura Ring and also on Polar 10 Patch, how cone a continuous Heart Rate variability is obtained without using 3rd electrode n that too without keeping a finger on it?. Is the Tech used in Oura Ring and Ploar 10 is totally different from other smart watches tech used including Apple watches and Samsung galaxy watch? I kindly request you to give me a detailed reply sir on this tech used Life from. INDIA Thanks n regards
Oura's crazy subscribtion model is putting me WAY OFF! I was going to buy it, but I'm not satisfied by providing my data to someone, and then paying them to get it back! That is completely and utterly dumb!
Hello, Can you help me please find a reseller in the US, I would like to buy a few rings but can't quite find someone's email to contact for the ring. if you could help me it would be appreciated. Thank you!
I've seen 3/4 videos and I have to say: finally some calculations about the performance of these devices, and great videos too🔝 I have a curiosity about the heart rate sensor: is it good the one incorporated by Fitbit, Xiaomi Mi Band and in general the fitness bands? Is at least somewhat accurate the heart rate number they give?
Wow, thanks Luigi! So, in my experience most of them are decent at tracking HR, though some tend to have some bias. I have not quantified this (yet), but my FitBit seems to be a bit low sometimes. However, the technology behind measuring HR on the wrist is quite advanced by now, so most will at least give a good indication. Though there will be some bad apples in there, so if you are looking for a specific device, generally a well established brand is a safer choice I would think. Anyhow, these are just my first thoughts, hope it answers your question!
@@TheQuantifiedScientist Thanks for the informations, man😉 It would be really cool if you would be able to quantify something like the Mi band 4/5, which are by far the most bought wearable in the world, but the Fitbit would be ok too, I think they're quite similar even if the price range is somewhat different. Oh, of course you have a new subscriber, I'm currently doing my specialization in statistics but for economics, and watching a "mad scientist" like you who measured the self-reported stress for 3 years straight is awesome ahah, great stuff!
I was fairly certain that heart rate increases when inhaling and decreases when exhaling, which is why longer exhales than inhales can calm people down. This is the opposite of what is said in the video? Am I wrong in my assumptions?
Great videos! one tiny thing, the Polar is not considered as medical ground truth for ECG, you should really get a medical ECG device for such comparisons. Please continue with more videos! :)
Hi Fezzik! Of course you are right :-). But for these purposes I think the Polar was good enough, especially since the results matched so well. Have a wonderful day!!
Great video! Do you know any wearable (strap with ecg or somethings like that) which can be used to get ECG 24/7 with good resolution (to process raw data for HRV analysis etc) and can work offline for a few days and then sync to phone/cloud over BLE and then export raw ecg data? Right now i'm using polar h10 with Elite HRV, but there is few problems - the hrv app sometimes restarted and loses recordings, and the most thing to worry with polar is permanentl bluetooth signal emmitting near my hearth and that can be dangeroues for health. So i'm looking for offline solution, maybe you know something? Thanks
Hi Max, I have to say I am not sure. There are all sort of devices being developed now to continuously measure ECG signals, but I have no experience with their reliability. For example, with a quick google search I found: www.welchallyn.com/en/products/categories/cardiopulmonary/wearable-ecg-monitors/tagecg-wearable-ecg-sensor.html ; www.vivalnk.com/ecg-monitor ; www.amazon.co.uk/EKG-Heart-Rate-Monitor-Electrocardiograph/dp/B073VW2ZZV . But as I said, no experience with these :-). What is your goal with the measurements? Thanks for commenting!
@@TheQuantifiedScientist Thanks for asnwer! TAGecg sensor looks good, but "A/D Sampling Rate: 250 Hz" are you sure it is enough for good ECG quality? As i'm aware most ppl recommending at least 500Hz with a better choise of 1000Hz. Vivalnk's "ECG: 128 Hz" seems to be not enough too... The one from amazon is 200 Hz. So right now my polar h10 beats them with 1000Hz sample rate, but there is no way to get raw ECG data from sensor, because it not stored... My main goal is to increase lognevity & lifespan. (You can begin with David Sinclair's book if you interested, then deep more into mTOR, AMPK, SIRT, fasting - Valter Lungo, Autophagy induction - Guido Kroemer etc). One of the key thing is to monitor some of self data, check where it goes, what to work on etc. CVD diseases are biggest reason of people dying on our planet, so for now i'm focusing on getting detailed monitoring my heart data, which can analysed, processed and be shared with doctors. Also during collecting some data (i'm collecting food & nutrients, drink, toilet actions, gym excercises, stress, mood - 100+ events per day, and some 3rd party tools like withings sleep/body cardio/go and some blood/urine/ultrasound scans etc) i want to find some correlations and check some ideas (for examples check if some molecules like NMN or Resveratrol have effect on my body). And see how fast my body is aging and where im at with it :) Precious ECG data (for example how hearth reacts to stress) should be a huge indicator for measuring health status, trends, changes in body.
Noted! Did not know it was coming. I have to see what I can do with my budget, but it seems like a really cool device, and not overly expensive at 250/300 euro. Thanks for the suggestion!
@@TheQuantifiedScientist btw, I was in touch with their support regarding the sleep tracking as was wondering how wrist sleep tracking compares to the other ways of doing so, particularly, their "Withings Sleep Analyzer". Today got an answer that Sleep Analyzer should be more accurate as uses more advanced ways of tracking including ballistocardiography (BCG). Given how you reviewed other trackers vs highly accurate device, now I'm suuuper interested in your review of Sleep Analyzer :)
WzR Can’t speak in the same detail as the quantified scientist, but my experience with the withings sleep analyzer has been good and I love that it doesn’t intrude on my sleep or require me to wear anything. Also it has no batteries so nothing to remember to charge = although you do have to plug it in to the wall.
Danke für das Video, ich habe schon festgestellt, dass mir Werte fehlen, wenn meine Finger zu sehr angeschwollen sind in der Nacht. Deshalb nutze ich den Ring hauptsächlich links.
Hi. I am interested in HRV. Thought about Oura Ring, but then came across Elite HRV site. I am using one of their approved devices (Polar H9 strap - a new device that is similar to H10) . Downloaded Elite HRV to my iPhone and take measurements every morning. Have you tried Elite HRV? What is your opinion on that ? They also promote their own, finger measurement-based device. I believe, however, that nothing is more accurate than a chest strap. Thanks
Hi Israel! I actually used Elite HRV to measure the raw RR-intervals for this video, and I used some computer code to analyze that data. I think Elite HRV works fine, it seems to be well developed, though I really only used the raw data. I don't know about the processing of this, but I assume (given the userbase) that enough time has been invested in this. Yes, I also think a chest strap (as long as it is well fitting) should perform best in most cases. I hope this answers your question. Have a wonderful day!
I just found your channel because of the oura ring vs. EEG video and i love your channel! I'm trying to figure out if i will buy the oura ring or the galaxy watch 3. Will you test galaxy watch3? Or have you looked at it? Greetings from northern germany :)
Hi Niklas, unfortunately I have no experience with the galaxy watch. If you want to track your general health, I think the Oura ring is pretty good, but for sleep tracking it is not the best. What are you looking for?
@@TheQuantifiedScientist thanks for the answer! I'm looking for something to track general health + especially things like blood pressure, blood oxygen and pulse. The Galaxy watch3 seems like a good device for that + it'll get an EKG. I already ordered it and will compare the results with medical devices (my uncle is a doctor). If you want to, I could send you my results in a few weeks!
Does OURA really measure HRV? I believe it's rather pulse rate variability, right? I mean, OURA doesn't measure heart rate, it measures pulse rate. It's a big difference for scientists ;-). It might fit for young healthy individuals but potentially can be misleading with people who have cardio-vascular conditions...
Hi, appreciate your thoughts on the Samsung Galaxy active watch, am waiting for their EKG app (for NZ) but understand is now available in the US. Great work. Regards Mike
Great review. Would be great to do the same for Whoop. One irrelevant observation; bit odd how your HR takes hours to go down (& HRV to go up). Do you eat or exercise really late??
I've been using Camera Heart Rate Variability on the iPhone for years. I always look at rmssd. Is that what you're referring to? Now the Apple Watch uses sdnn instead. Is that a similar measurement but a little higher?
Hi Rob, can you please explain the difference between HRV and arrhythmia. Although I believe in the scientific findings, I find it hard to understand why high variability is good? I thought high variability would be the same as arrhythmia. But apparently not?
Hi Azat, I would need to dig into this a bit deeper to give a comprehensive answer, but I expect it all has to do with the underlying cause of the HRV. Normal HRV "is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion.". (www.health.harvard.edu/blog/heart-rate-variability-new-way-track-well-2017112212789 ). From what I understand arrhythmia is "due to problems with the electrical conduction system of the heart." (wikipedia), and it can also go hand in hand with abnormal heart rhythms (so the way the heart beats) . However, in tracking HRV, it might be that I cannot easily distinguish between the "good" HRV and arrhythmia. Both cause variation in the time between heart-beats, but the underlying cause is different. I am not a doctor or a HRV expert, but this is my best understanding. I would have to take some time to read more about it to give you a better answer. Hope this helps though! Have a great day!
I came across these terms while looking at the readiness score in sleep tracking. I can’t find a video about readiness scores, but your videos keep popping up explaining the ingredients. Subscribed!
Hello I own a fenix 6x and oura ring Garmin has just updated the software and now connects all variables when it comes to accurately indicating that you are rested enough to train Could you check it out?
May I ask what software did you use to take the HRV measurements? As far as I know, there are some apps out there such as Elite HRV but I am not sure how accurate they are.
Hi Silje-Sofie, I actually plan to compare a few FitBit models (Fitbit Charge 2, Charge 3, Charge 4 and Fitbit Ionic). I suspect that if all of those turn out to be similar, that you versa 2 will also perform similarly. Stay tuned for that video :-D. Have a great day!
Great quality video my brother. I am looking at the Oura ring for HRv and sleep monitoring, but I read some research that raised serious questions about the veracity of the sleep data that Oura ring provides. Have you seen this research? If so, be great to hear what you thought of it, thanks :)
Hi! Thanks for the compliment :-) . I am actually quite happy with my views at this point already, hopefully I can continue to grow and improve my videos :-D. Have a great day!
Great video and data! I believe some of the missing data may have been from the fit of your ring. It looked slightly loose which can cause inconsistencies in the readings, especially during movements during sleep.
Hi! So I use the Oura ring and a FitbIt Charge 4 continuously. I also have some more custom devices, like a device that measures my light exposure and one for environmental temperature. I used the Spire Stone for a few years, but the charger broke, and they do not produce them any more... I track my home cycling with the Tacx Neo 2 Smart trainer.
