Sleep Tracking

What does your ave HR post against your sleep, and have you checked your HR to see if there are any major blips on it, showing that you definitely woke.
Maybe your HR didn’t move significantly and if you haven’t stood up, its very likely that it might not record it a wake period. I suspect that in your wake periods it was recorded as light sleep, just like it does if you sit and watch tv during your sleep time, don’t move much and your HR lowers similar to sleep - you get a massive light sleep patch, which goes to wake up when you stand up to go to bed.
So if you do wake and want to see a wake period, maybe move around a lot / stand up…

Yesterday I had an interesting situation.
I took the watch off after bathing around 24:00, put it back on around 4:00 (then it started measuring heart rate again). I went to bed and woke up around 11:30. The watch counted almost 12 hours of sleep! For me, compared to Suunto 7 this watch is not suitable for sleep monitoring. maybe they will fix something in the next update. -
@mlatej it does not base sleep to heart rate. So yeah if you take the watch off during the sleep time it will register sleep. You can also turn off the 24/7 hr and still track your sleep …
-
@mlatej
And I’m pretty sure it is also stated in the user manual -
@sartoric The manual does not say that the watch will measure sleep when you take it off. It does say that it relies on an accelerometer. It makes no sense that when the watch is motionless (for example, lying on a desk) it measures this as deep sleep…
-
@mlatej
I guess the manual has been updated when deep sleep data was added, anyway it actually uses accelerometer as you normally don’t move that much while you’re deep sleeping, so the watch guess it’s “right”
The only way for the watch to start monitoring sleep is to check the sleeping range time and then any movements as it cannot check your brainwaves
-
@sartoric correct.
-
@dimitrios-kanellopoulos Well, it’s not quite like that either
In my watch I have set my sleep time to be between 4:15 and 13:45. In the manual it is written that outside these hours the sleep will not be counted. In my watch, however, sleep is counted outside of these hours… That is why it counted only 12 hours of sleep then, and today, despite the fact that I got up far after 13:45, it still counted it as sleep.
I don’t really know how it works, but maybe I will learn it somehow, or there will be an update which will sort it out
-
@mlatej I truly believe the device has an issue if you wore it after waking up.
Just for my sanity and sorry if you had answerd and didn’t see it so far.
Does the device count steps. ?
-
@dimitrios-kanellopoulos Hmmm, it looks like it’s counting, but I have no way to check if it’s working well except by manually counting the steps
What I do know is that the Raise to wake function works pretty clumsy… I think this function uses accelerometer too. Here I created a thread about this issue: https://forum.suunto.com/topic/6711/raise-to-wake
Maybe there is something wrong with my accelerometer? -
I noticed this behavior with S5. It can detect quite good when i fall a sleep. But it often doesn’t recognize when i wake up. I must get up from bed and walk or move with hands for a while for watch to notice that i woke up. And during night it sometimes doesn’t notice i got up and went to toilete. So if i am away from bed for only few minutes, it often didn’t notice at all. There is room for improvement, but i am not sure what precision can be achivied with these kind of device.
-
@hristijan-petreski totaly agree, same with S5.

Last night wake up, went to kitchen, eat, go to bathroom, back to sleep, still s9p got continuous sleep.
Also I didn’t went to sleep at that time, I may have lay down on bed but was on the phone having a video call and moved.
It is not first time this happens . If I can help the devs let me know.

@andré-faria but it has awake 33h. It won’t segment the sleep.

Ok that is already more clear. But since in the end my real go to sleep time was like 22:40 and not 21:38 (between those timings I was on bed on the phone, moving and as I said , get up, kitchen, prepare something to eat, bathroom) I would think the watch would detect that 21:38 was not at all the sleeping hour.
At least that was what happened when I had Garmin (fr45,245, f6s). Maybe something related to sensitivy of accelerometer? -
@andré-faria hmm
-
@andré-faria For me it’s the other way around: went to toilette on 5:15 and back to bed (which is the room next door - 7m to walk, took as a whole 2 minutes) and the Suunto S9P thinks I am awake
. Sleeptime set to 21:30-07:15, Auto DND 23:00 to 6:00 . Also fell asleep around 23:20 and not an hour later like it assumes.
But also have near perfect hits with the S9P. The best sleep metrics I got from my Fitbit devices, second best from Polar. Suunto is on par with Garmin, but in the Garmin app you could edit the Start- and endtime which then was filled up with light sleep.

@andré-faria
You would need to try and see your wake periods against your time, which I don’t think the suunto shows as a graph from what I can remember, but as you do have wake time it will have picked up when you were up and about.In regards to not picking up your conference call that is nothing new - if you are sitting reasonably still, and your HR is down (i.e. watching TV, lying on the bed) the watch quite reasonably assumes that you have fallen asleep and will record it as light sleep. In future make a note to make a serious movement every 15/20 mins (still trying to work out the period it uses) or make your sleep time later.
It is one of the things that I like in how Garmin shows the same sleep tracking, in that it also provides details of the sleep stages against a time on a graph, so you can see the sleep cycles etc, and it can show movement, respiration and SPO2 readings against your stages. I just wish it also had the duration trend graphs that suunto has which you can put average HR etc against them, as I found that super useful when checking out the my sleeping trends.

@jamie-bg Hi Jamie. Which devices did you use for the sleep tracking?
-
@patrick-löffler
I have used a variety in the past. used to use fitness bands from huawei, sony, fitbit - all of them said I had great sleep despite my chronic fatigue, so stopped using them - turns out my chronic fatigue was due to obstructive apnea @ +60apnea/hour, which was diagnosed by doctors after a sleep clinic session.I now track my sleep with a CPAP machine, S7 and Fenix 6x Pro Solar.
The CPAP machine does an excellent job of duration, gives me details on the number of apnea which points to whether I am getting deep/rem sleep, and show me mask leakage (have 12bars being pumped down me, so can be prone to leakage, which can increase apnea. As a general rule I now generally am less than 3apnea per hour (as long as less than 14 it means you will be getting rem/deep sleep).
The suunto 7 (firstbeat sleep tracking) and the Fenix 6x Pro (same firstbeat sleep tracking) - only difference is with amount of recovery it produces for body resources (S7) and body battery (F6), as S7 uses firstbeat recovery rate and its rubbish- far too few resources, whereas the F6 uses Garmin’s recovery rate which provides a much higher recovery rate on the same quality score (both use firstbeat quality score), and is much more in line with how my body feels.
I find the firstbeat sleep tracking based on duration normally understates it a little, but most I have seen is 30mins, it also occasionally will capture me as light sleep when siitting very still watching a movie, but happens less with F6 as Pulse Ox light lets me know, however the sleep cycles seem very relatable and seem realistic based on how normal sleep cycles work i.e. never see rem in first 90mins, and the first rem is always a quick session, deep sleep is pretty much always before first REM session and is normally between 20-40mins. Deep and rem sleep are pretty much always over 25% of total sleep - which pretty much tracks to what is the normal. Of course sometimes when I drink alcohol before bed, eat something, and or am coming down with something (as the govt infecting me covid showed) it can adjust and show in my sleep cycles and quality - which is correct - it should.
