Great review thank you! I've had mine for about a year and what made me do research on it was the heart rate monitor. I was diagnosed with an inoperable cerebral aneurysm about four years ago. The reason for it not being operable (coil or clip) is because of its location (Anterior Communicating Artery) and size (small, thank God). I suffer from PTSD, Anxiety, and Depression so I need to keep my heart rate and blood pressure in check. HARD TO DO when being told you could have a stroke any time! But I have learned to let go of what I can't control and focus on what I can. Oura Ring has helped me stay in control of my wellness, for sure! Thanks again for this review, I just emailed it to friends. I "liked and subscribed" so I will be back! ~ Aloha, Christine
Finishing day 6 with Oura Ring. My first morning was 67 and I was really having to push myself to get through my day. Today I am up to 94. I am serious about getting quality sleep and this combined with my CPAP is getting me closer to my goal.
My Oura ring is finally here! On the truck out for delivery today. I have an Apple Watch and a Fitbit Charge 2. I am interested to see how the sleep monitoring compares. I’m also very interested in my body temps throughout the night. I wake up sometimes with hot flashes. Also want to get more active and I find collecting data motivating. Thanks for the video!
Well explained, Dr.Choi. I have fibromyalgia and am looking for a good health tracker. I was looking for videos explaining what the Oura ring is. Yours is only video I’ve come across with a clear and good explanation. I’m interested in getting one. Thanks.
Forget about RUclips's speed crap! Use Video Speed Controller. Using HOTKEYS you can speed it up in 0.10x increments up to 16x... so... yeah. chrome.google.com/webstore/detail/video-speed-controller/nffaoalbilbmmfgbnbgppjihopabppdk
According to the Sleep Junkies podcast with Curzio, he talks about the difficulty in accurately measuring/interpreting EEG waves (see 59m mark). The takeaway seems to be that it's near impossible to get accurate data at home using consumer-grade devices around the head (ex. UMindSleep S1), so I can only imagine how unreliable the data is from devices that claim to do it via the finger/wrist (Oura/sleeploop)! Similarly, Mathew Walker , 'skeptical cardiologist' and nootropedia analyze the data (ex. pubmed 28323455).
Hello Dr. Choi, thank you for the review. I have a question that you brought up during the video but I did not fully understand about putting the ring on airplane mode. If you put the ring on airplane mode, does the ring continue to record all your stats and then when you turn on Bluetooth again, it sends the info to the app? Also, if one uses the app to put the ring on airplane mode, then what wireless signal is the ring using that still connects to the phone that gives one control to turn off Bluetooth? Thanks again!
how is it powered? which finger does it go on? does it need wifi to operate? I have been monitoring my sleep with a trail camera, this ring thing looks awesome!
Dang. Love to have a real doctor reviewing this. I just did my review of it and it is much less informative... This is great. More docs should review the wearables! The tech is out there but doesnt get much credibility.
How can a sensor on your finger know how your sleep was? WIthout measuring EEG? Does it just come up with a "guess" based on your heart rate and body temperature? If it is not on your head when you sleep I just can not see how you can use the date it gives you?
Thanks for this review. How much reliant is the ring on bluetooth, e.g. how long can you have bluetooth deactivated? I imagine the ring can only hold so much data before it need sto transfer it to the smartphone app.
You’re welcome! The battery is the concern if you turn off bluetooth. I have left it in airplane mode only to find that the battery died. I dock and top up charge once every day or so.
Waiting for my oura ring to arrive. Your video was very helpful. I’ve never owned a health monitoring device because of the same issue (bulkiness, irritability) but the ring was a different idea.. does it need to be charged ? If anyone has measured it with an emf meter that would be good info to pass along here!
It does come with a ring charger, which charges very quickly. The ring can be placed in airplane mode. I sync the ring about once a day, charge it, and then put it back in airplane mode.
I'm intrigued by the Oura ring, although the company seems pretty messed up in terms and delivery, commitments and production. Beyond that, my sleep doctor swears that the only way to measure REM sleep is an EEG based polysomnogram ... and she claims the American Sleep Association considers anything short of this mostly a gimmick. Either they're protecting traditional sleep analysis (and their revenue) or Oura is making claims that are suspect.
I've wondered the same thing around accuracy. However, it is still valuable to looking at the changes over time, assuming consistent variance in measurements.
Dr. Aron Choi, ND Completely agree. It’s worth noting that decades ago the medical community was suspicious of oral mercury thermometers. Putting clinical tools in patient’s hands threatens their revenue.
Dr. Aron Choi, ND 22 months ago I was forced off of a benzodiazepine as a result of that I’m in bed in severe pain I don’t think I sleep more than an hour a day because I can never ever get comfortable ever the only semi-relief I get is sitting on the toilet without going into all my symptoms anyway I’m considering ordering one of these to see actually how much sleep I do get and how my brain is recovering
Hey doc I ordered a oura ring!! Just got the sizer today I am a size 11. I chose silver as puter just looks cheap anyways that doesn’t matter. Tomorrow I will confirm my size. I think I am going to be way more active with a step counter vs my iPhone which counts my driving as walking haha.
Oura says it is very very little. Don’t remember the exact number. It’s much less than a cell phone though. I like to use “universal precautions.” I minimize exposure as much as reasonably possible.
It provides HR while asleep and during “Moments” where you can set a timer for meditation/breathing and it will measure your HR and HRV. It does not provide instantaneous HR. A small drawback but not a deal breaker for me.
Where did you read that nocturnal HRV is not as accurate? It tracks HRV while you sleep. It can now also can track HRV during "Moments" when you meditate or do a breathing practice for more than 3-5 minutes. These articles explain more. help.ouraring.com/en/articles/757959-heart-rate-variability ouraring.com/how-to-measure-heart-rate-variability/
Be careful if you're buying this to use with Hauwei Mate 20 Pro. They have bluetooth connectivity issues and Oura are useless at customer service as they appear to have about 2 people working there EDIT: Don't buy one of these is you're using an Android phone. Just look at the feedback for their app on Google Play. Tons of negative feedback from users unable to connect the ring to their phone.
@@draronchoi Well, I need to correct myself on this score. I returned my V1 ring and have now tried the V2 which does work fine with my phone, although the connection is a little flaky, particularly during the day when it often stalls when updating. A simple uninstall and re-install solves that but is something Oura could look at. Having all this data is really great and although it's early days yet I'm going to have fun modifying my behaviour to optimise results as far as possible. I do have a slight issue with their sleep breakdown. Their data has seemingly been biased towards younger users and I'm not certain their breakdown analysis into REM, Light and Deep holds true for older users like me. The study that was carried out and which they cite on their web pages was done using 41 people between 14 and 20, not old farts like me. On my first two nights they're suggesting I had over 5 hrs REM sleep and 1 min of Deep sleep which is nonsense. I also use a Lucid Dream monitor which uses 7 EEG electrodes and I've never had more than 2 hrs at absolute max of REM sleep. I think they probably need to tweak their algorithm for older users. Other than that I'm really happy with what it's collecting as I'm a bit of a data freak....
@@sshroot5565 That's good. After two days I can say the steps data is wildly inaccurate by at least 1000 steps each day. Only to be expected with a ring I suppose, especially as I use a keyboard for much of the day. The accuracy of the sleep data is also a little flaky as it's trying to tell me my REM periods last 5-6hrs daily which is nonsense. Even their study showed the sleep data had a high degree of inaccuracy. But it's early days yet and I'll see how I get on.
I have a Hauwei p10 and its been working fine for about 3 months. It wouldn't connect one time, so I restarted the phone, and have never had an issue since. I have a friend that uses his with a differ brand android phone and he has no issues either.
I really want to get one for myself and my partner. Cos I have some health issues (back problems, anxiety ) . Do you think its gonna be good for me ?. Thx.
It may not directly help those things, but if you find out that you wake up a lot during the night or are not getting deep restorative sleep, then you have data about an underlying issue.
yujinn g yes but It’s not a ‘fitness’ tracker. Heart rate, Heart Rate Variability, sleep duration, sleep level, body temperature. Calories burned, pedometer. This is a sleep min/max tool.

Never expect this to go down or similar, there are a lot of smart rings out there but the quality is low, until now Oura and Motiv Ring are the best and now for years the price has not changed, just too much tech on it to be a cheap device.
@@astrit i'll take that into consideration. i looked at the garmin 935 and i really like it aesthetically, but the sensors on this ring and its suite of tracking features seem to be more aligned with what i'll actually use
I used to wear a Garmin primarily for running. It was great for that purpose but the Oura ring is a much more sophisticated health tracker. Yes it will be cheaper a year from now...all tech goes obsolete. You can wait a year but you lose the benefits of actually using the tech and improving your life.

First night with my oura ring was amazing this device is deadly accurate unlike junky Fitbit tech.
Thanks a lot for taking the time to make this video man. Very felpful and clear.
My pleasure!
Great Video Aron. Thanks for the info. I have used Whoop, Apple Watch and I am really considering Oura tooo
Great review!
Ha! I’m single, never wear jewelry but prefer a ring vs a watch. I wore it for the first time and several coworkers asked if I got engaged, lol.
the oura ring has been such a game changer for me
This review was so helpful. Thanks a ton man!! :)
is there a new version coming this year?
Very informative video, thanks

According to the Sleep Junkies podcast with Curzio, he talks about the difficulty in accurately measuring/interpreting EEG waves (see 59m mark). The takeaway seems to be that it's near impossible to get accurate data at home using consumer-grade devices around the head (ex.

Similarly, Mathew Walker , 'skeptical cardiologist' and nootropedia analyze the data (ex. pubmed 28323455).
Agreed that consumer grade devices are not perfect. However, it does provide helpful data to see trends. I’ll check out the studies, thanks.

It does record while in airplane mode but will not sync until put back on the charger. I had the same question before using it!
how is it powered?

does it need wifi to operate?

Thank you for your review.🙏😺
You don't have to leave bluetooth on for fitbit. You just sync it in the morning.
It would have been great if you brought some insights as Doctor, beyond what’s already said in the app.

Thanks for sharing the information Aron. Really appreciate it.
Just received mine and it’s an incredible piece of tech, I’d go as far to say it’s a masterpiece of technology...amazing

Wish it could track blood insulin/glucose as well.

The rare ability of Oura ring is measuring HRV that few devices can do which is however not mentioned here.

Is it true that the HRV (Heart Rate Variability) is only measured during sleep? If so, that would be a major drawback.
Vishal - For now yes BUT they should be releasing on demand HRV in “early 2019.” Should be out any time now.
It measures throughout the day
Compare to Apple Watch?? You think it’s performance is better?

Love my Oura ring. Just wish I could afford to purchase one for everyone in my family. :-)
Cool-looking gadget. Would try one out, but not at the price of an Apple watch. This needs to be Fitbit price territory.
would you know the radiation of the ring when it is connected to the ph during sleep? wonder if it is in the safety zone. thx

Is it waterproof?
Yes. I shower, sauna, and workout with it.
Does it measure your resting heart rate on demand or only over night?
I would like to know anytime.
It provides HR while asleep and during “Moments” where you can set a timer for meditation/breathing and it will measure your HR and HRV. It does not provide instantaneous HR. A small drawback but not a deal breaker for me.
How is this ring powered ???
There is a small docking usb-c charger.
I read that nocturnal HRV is not as accurate or hasn't been studied well. So does Oura ring give nocturnal HRV values?
