    Hehe,

    could be a scenario. But I don't remember a thing, so it could be anything.
    Have to track that a little bit if a regular pattern occurs like time after falling asleep or specific time-frames in the night.

    Edit says:
    I messed up the screenshot upload - I changed the original post above to show the heartrate. Don't know how that happened when writing the post. Sorry :-D

    Edit 2:
    The first spike on the wednesday-HR-shot is from my cat that decided to shout into my ear when I was nearly asleep and scared the heck out of me. =/

    Really interesting data, thanks! I'm intrigued that you set it on Wednesday night, and it "detected" that you fell asleep at 11:49. Kinda suggests that the Band "could" automatically detect sleep. I also think -- if accurate -- that those swings up to ~100BPM are a serious concern. Maybe you could post a workout with, say, 30 minutes of walking? Or you mentioned preferring stationary exercises, no? Something aerobic and sustained could be interesting to see.

    Hey,

    just hijacking the thread for a quick heads-up.
    Today I tested the GPS on the band when walking with a colleague to grab lunch. It was pretty much 1km away and we stopped at his car for a minute to grab a jacket. That's the result from the walk in a pretty decent pace.
    walking_1km.jpg
    heartrate_1km.jpg

    So in the background of the HR you can see the pace with the little stop at the car. But it should be pretty normal. Just checked my HR when sitting at the PC - shows around 69 - 72. Nothing rad in my opinion. I did a workout on Monday and was on the crosstrainer for half an hour and it showed a max HR of 174 - which is pretty much everything I could push out and after that half an hour I had not much energy left in my body - so it was pretty hard exercise for me.

    Like I said with the spikes when sleeping:
    I have no clue where they come from. I'm not remembering that I was awake anytime near that timeframe and I have no idea of a bad dream. No sweaty shirt when waking up or something like that. What could be a reasonable explanation for that is, that I know I'm snoring and my girlfriend has to give me a pretty good kick that I stop it when she wakes up from it. Maybe that's causing the "issue" that that is the time when I'm snoring and my body doesn't get the full breath of air it wants and naturally increases my heart rate for it.
    I'm going to look if I can find a solution to record the audio of the night and keep checking the Band data just to know if that's happening or if my cat's are jumping around in our bed and my body gets disturbed while sleeping.

    These would be the first explanations that come to my mind.
    But thanks for your opinion and your thoughts. I'm definitely keeping an eye (and ear aka microphone) out for this spike-behavior.
    I mean it shouldn't be too serious because it's approx. the heart rate when I'm walking in a decent pace and nothing like 180+ and beyond. :-)

    Regards,

    You guys sleep well. As a 27 year old male as a full-time student and a 40 hour a week schedule, I sleep pretty bad. Average of about 5 hours of sleep and maybe at least 1 hour and 30 minutes of deep sleep. How am I living? lol...

    All you guys with mid-40's resting HRs need to STRESS more! Or maybe you're just a bunch of 23-year-olds with no spouse, children, or pets! The rest of us have a lot to worry about!

    I am early 30's 280lb 6'3 and my resting is in the 40's when I remember to cut the dang tracker on. Wish it was automatic.

    Here is a fairly typical night for me. Awake for a bit tossing and turning. I have RA so getting comfortable can take a while.

    Deep sleep in 15 minutes? No problem there. The tossing and turning, turning and tossing looks to be about midnight.

    I don't think you can.....or at least I can't find it either. You can view it on the web dashboard, though.

    looks like even though the Band was on the correct local time on my trip to Japan, it still shows my sleep on EDT
    on the website...
    Of course that screws up the average bedtime and wake up time...
    interesting...

    I'm guessing the website normalized all the times to a single time zone. At least for the graph.

    Sure, in May I had 8 nights optimal. They always fall on my days off......otherwise I only get 4 to 5 hours when I have to get up at 1 am.

    I had some too, but I still wonder how it is determined, since the efficiency was bad, I woke up pretty often...:

    Also I find it quite intersting that you see on the Heart Rate how you actually feeling. When everything is OK and I'm working during the day I usually have a resting HR of ~45. When I'm at home (couple days off) it usually goes down to ~40. Tonight I had back pain, didn't realize it during sleep (in my opinion) and had ~51. And mid of May i was in pain and even had to go to the hospital and my HR was ~70 during the periods I slept.

    This is one I could imagine that it's maybe optimal:

    Wow, that's some serious deep sleeping there. I have had quite a few good nights but I am missing on optimal on my days off due to consumption of alcohol and the summary tells me that!. A beer or two before bed wrecks the night in terms of quality, regardless of quantity, and this can be born out by how i feel the next day.

    I don't know if other have found this but wearing the band has made me very conscious that I am getting insufficient quality sleep and as a result has reduced my alcohol consumption quite a bit.

    I'm already a pretty serious lightweight (when it comes to alcohol) so no effect on my drinking habits, but...this is going to sound a bit odd but looking at my sleep data has also made me more "mindful" about "how" I sleep. I can't say I deliberately put my head on the pillow and think, "OK TONIGHT YOU'RE GOING TO SLEEP WELL, DAMMIT!" But there is an intentional aspect to it, and sure enough, the "desire" or "will" to be a bit more restful has seemingly led to better data on the Band. I guess it's a kind of delayed biofeedback of sorts.

    Yes, I understand. I have even started looking at techniques to help get to sleep such as Dr Andrew Weil 4-7-8 technique. It's a;; about being more aware of your health rather than just the fitness and exercise bit.

    I've given up on the "restoration" measurement. I've had a grand total of one night of "good" restoration -- ever -- with the rest almost uniformly low. I've compared all the data and it appears totally arbitrary, and has nothing to do with time asleep, light versus deep sleep, number of times awake or anything else.

    I can say restoration does not seem to be just heartrate. My "good" night my heart rate was 65. Next night it was 58 but that was a "low." Both days had about the same level of physical activity. Whatever secret sauce they are using, I'm not impressed.

    It is pretty mysterious. Last month I downloaded my sleep data and began to look for a linear combination of factors (e.g., Duration + Sleep efficiency + HR + etc.) that predicted Restoration but didn't make much progress. Eyeballing it, I can see 2 days in the month, one that's "Good" and another that's "Moderate" and yet the stats themselves looks the same. That suggests (OHNO!) that there is also an "historical" factor, i.e, a moving window or average that includes the influence of recent days. If that's the case we'll never reverse engineer the formula, or even which measurements are being used.

    On a related note, I now regularly get, "Your restoration was delayed in the beginning of your sleep. Try minimizing physical and mental stress close to your bedtime." Or...wait!...I just checked past days and the notification is gone...weird. But it's there for this morning. Seems I get it every morning and then it's gone the next day? If so that's an odd bug. Anyway, yeah...huge grain of salt!

    OH! And here's another one I never noticed before: on my phone (Health app) the latest session is "Thu 6/4" and yet those same data are showing up as "Today, June 5, 2015" on the Dashboard. So Phone = "The day I go to sleep" and Dashboard = "The day I wake up." When did that start happening???

    This thread has some interesting discussion:
    Help Interpreting Sleep Restoration - Microsoft Community

    User RogMcc hypothesizes that the restoration measurement is based on how quickly your heart rate drops after you fall asleep. Not how low it drops eventually, but if there is an initial plunge. The one night of "Moderate" restoration I have my heart rate only dropped about 10bpm but it did so within the first hour of sleep. Every other night I have a more gradual drop, usually about 20bpm, but that's a restoration of "Low."
