Tbh the oura ring has been a game changer for a data nerd like me. I can easily see how some exercise in the day actually impacts my HRV[1] and then the quality of my sleep. Had a heavy night of drinking? Watch what the oura ring reports not just on the same night but even the next night :) Basically if you're thinking of starting your own "protocol" for sleep and would like to A/B test what works and what seems like…

Did you really need a $300 device to tell you that a night of drinking will undermine your sleep?

Cool! I have a Whoop. I purchased it before they started the subscription model. https://www.whoop.com/the-locker/team-thrive-average-hrv-on-...

Another view on the Oura thing: https://www.medpagetoday.com/practicemanagement/informationt...

It's rather skeptical. Choice quote:

[...] The SRI researchers studied 41 healthy adolescents and young adults (average age 17). Sleep data were recorded using the Oura ring and standard PSG on a single laboratory overnight. Metrics were compared using Bland-Altman plots and epoch-by-epoch analysis.

The ring accurately detected "light" and "deep" sleep in 65% and 51% of the sleep epochs, respectively. It also accurately detected 61% of REM sleep epochs, with an overall overestimation of PSG REM sleep (by about 17 min). When the ring misclassified PSG REM sleep, the algorithm usually classified the epoch as "light sleep" (76%).

These data suggest that the Oura Ring is virtually useless in telling you if you are in REM sleep versus deep or light sleep. [...]

The stats imply that it's very inaccurate in tracking sleep phases - you probably know better yourself the day after.

Hmm another sleep article. I'll share what I do. After being in the Army for a while, and waking up at 430 and going to bed at close to midnight for a long time during the week (there's no real "sleep schedule" overseas though) I've been working on tuning my sleep cycle for the seasons to great success. Over the last year I've been slightly altering my alarm each night based on when sunrise is (plus going to bed earl…

Can you add more details on how you handle seasons? This is something I've been wondering about. Do you shorten/lengthen your sleep? Or just shift it to always wake up at sunrise? I think shifting seasons might be one "natural" thing which our biology is not "naturally" attuned to, and a fixed-length day would probably be better (maybe we'll have it in the future on a space colony, by I digress).

Polysomnography seems like an area in desperate need of innovation to improve efficiency and lower cost. It is far too expensive for the entire undiagnosed sleep-deprived population to have a single sleep study let alone for those already diagnosed to have more frequent observation.

Does the Apple Watch do sleep tracking out of the box now? I was one of the 5 people who bought a Microsoft Band, and I really enjoyed the sleep tracking features. I still haven't pulled the trigger on an Apple Watch since switching to and iPhone because it (used to?) lack sleep tracking as a feature.

No. It still is intended to charge overnight. Apple store sells other sleep tracking products at this time.

There are sleep tracking apps that integrate with the health app, but I tried two of them (sleep++ and pillow) and I found them to be very inaccurate.

I have trouble justifying spending 314 euros on a sleep-tracking ring.

it depends. do you have 314 in disposable income? is health really important for you?

My problem is when this company fizzles out in 2 years and stops servicing or supporting their product.

If Apple make made something like this, I may bite.

If it's important to him he might ask his doctor or head to Cochrane Collab?
