The fact that the data in the official test is just interpreted by “experts” which can’t agree with each other makes me very sceptical.

[@nathanielblake8099]

exactly what i’m thinking! there’s no point at all in taking sleep stages seriously if that’s the case

[@Duci1989]

Exactly. Did he say that between those experts there can be 85% discrepancy? Thats huge.

[@quantifiedmax]

in validation studies, usually agreement between 5 experts is around 80-85%, so you dont have to be to sceptical. 85% disagreement is something unusual

[@BigEyeFluffy]

I got oura ring and returned it at the end of the allowed window. The light bleeding kept annoying me, it made my skin itch, and worst of all the readiness score was nonsense. I would get 98% on days I felt like a garbage truck ran me over while on days I got 60% I felt fantastic. Completely useless for making any changes in your lifestyle.

[@E-Nigma_]

@@BigEyeFluffy I’ve found you need time with these types of devices for them to be anyone than a best guess. When I first started tracking with apple watch, it was all over the place. After three years, I trust it. I think my whoop is more accurate, so for calories, I follow what whoop says on exertion (their only focus is data capture and analytics). For everything else, the Apple watch spits out pretty much what my other wearables do.

[@MigRx]

For the Apple Watch time being off on the second night, I remember there was a setting where the watch would detect you were awake if your phone is in use. I’m not sure if it’s there yet as this was maybe 2-4 years ago but it seems like a very helpful setting to have specially in the same ecosystem

[@gianni4302]

you would think any smart watch that is connected to your phone would be able to do this very easily

[@RomeuBertho]

Hi! I'm an Epix Pro 2 user, and I noticed that your Garmin is not recording SpO2. To get this metric, you must set the pulse ox sensor to read all day/ during sleep. SpO2 metric was handy in detecting something wrong with me. Next, I did a PSG and found out I have light to moderate apnea. Also, I like to track HRV and HR; every time those metrics get off track, it signals that I'm getting sick. Great video! 👏👏👏

[@AIKTV]

Hi, I have a short question regarding sleep tracking. There have been many tests on KZbin about how accurate it is. All well and good, but to be honest, no one has said so far why we even need sleep tracking and knowing which sleep cycles we go through. Why do I need it ? What can we actually do with it? What do I get out of it? How does it improve my life, and how do I interpret whether it's good or not?

[@babor_]

Let’s say 10 person sleeps for 8 hours per night. Each and every person will have a sleep score which determines the quality of sleep. There are several occasions when you slept for 7-8 hours and still feel tired, that’s where it comes handy to actually check your sleep quality. Several scientific study suggests when you sleep for 7 hours how much of that time period will be allocated by REM, Core and Deep sleep. Every sleep stages has benefits to your body. Some stages regulates your hormonal function, others helps you to recover from day to day work. You can do some googling and you will find the information. If you find a pattern that you aren’t sleeping properly then it’s time you do some changes or talk to a professional with the data on your hand.

[@bananasandbass]

@@AIKTV well for those of us with trouble sleeping, or getting good quality sleep, it can help you analyse sleep together with other activities and diet and things and then correlate and make adjustments in lifestyle to see if those changes help your sleep.

Super video, on an interesting topic. Always wondered how accurate those were. And generally thank for the topics you cover. It is super helpful. A suggestion for future videos.The background music/sound on this video is somehow super distracting and almost painful to listen to. It is perhaps the repetitiveness of the sound. Maybe use something, with a bit more variation, or perhaps longer before repeats.

Hey Shervin, Can create a video with a full review of the automatic sleep detection from Apple with WatchOS 11? something that covers both night sleep and naps, sleep mode and wake alerts + alerts if only using the auto detect... This will be very valuable as this feature has very little information out there much like it is not really a full fledged feature yet by Apple....

[@jamiebg3952]

what I would find intersting is if you did a test to find out how reactive all of these devices are to change i..e while I think it would be difficult for you to test for illness and injury it would entirely be possible to check for lifestyle/habit and how good they are at picking up those changes and reflecting them in their scores/data so that a user can make a make valid decisions about habits/lifestyle and if they are worth changing.

Everytime I do platelets donation (it takes an hour for a separator to pump blood there and back) my Apple Watch detects it as sleep. Also few days ago I was standing (yes standing, straight on my feet) in a queue, watching something on a phone, making a step forward from time to time, and my AW detected even a part of that as sleep.

[@Duci1989]

My experience with Garmin sleep tracking is terrible. It pretty much always takes my reading time before bed as sleep time, and it takes my wake up time (I stay in bed for some time after my kid wakes me) also as sleeping time. Also I have small kids and they tend to wake me a lot during the night. Regularly I wake up feeling like total crap after waking up multiple times and Garmin morning report will tell me my sleep was "continuous" and had "great recovery". So I share your conclusion that it's all useless and can pretty much be ignored completely.

i’m still looking for anyone to explain what the data means….. what is considered better or worse data for overall health regarding sleep tracking and how to improve. as much as I love the pretty graphs, even if the Apple Watch is somewhat accurate. I have no idea what data parameters are considered good or bad or favorable or unfavorable information. For now, I will keep tracking my sleep, looking at the pretty graphs in the morning over coffee and going about my day with absolutely no information of the quality of my sleep.

[@johnnyxd6065]

its literally useless, because as you can see in the video, one night apple watch can be somewhat accurate for deep sleep but light sleep off and the other night otherwise, so you cannot even see any trend or patterns as its making different mistakes each night
