I my experience, the most important thing is, wake up when you wake up. Don’t go back to sleep because you feel like you should, or the alarm has 20 more minutes. If you’re awake, get moving.
I feel like going back down signals to my body that this is going to be a lazy day and it should settle in, instead of firing up all systems.
I don't particularly want to remember to put it on every night. I know Nokia launched a mattress pad recently (https://health.nokia.com/gr/en/sleep) but I'm concerned about how reliable this is if I don't sleep exactly on top of it. (Plus I don't know how this could actually tell anything like sleep cycles and what not, or even detect that I'm asleep vs. watching TV in bed)
1. The researcher is also an entrepreneur whose product's sales depend on people thinking Fitbit isn't good enough. https://sonicsleepcoach.com/about-dr-dan/ 2. The quote lumps Fitbit and Apple Watch together in terms of how frequently heart rate is measured, when there's a 60x difference. A sincere quote would be more along the lines of "Apple Watch's 1-5 minute sample rate certainly isn't enough, but even Fitbit's 1-5 second sample rate won't give the accuracy you need..." 3. He doesn't say what's wrong with any published study showing sleep stage accuracy of Fitbit, notably https://academic.oup.com/sleep/article/40/suppl_1/A26/378095...
I haven't yet received the newer model, but it seems to solve the issue of limited battery life in the previous model and the ring is also significantly smaller.
I wonder if you considered that maybe I use my bed throughout the day for non-sleep-related activities.
I wonder if you considered that "watching TV" might have been an example, and I don't actually have a TV in my bedroom.
I have to assume getting up at the end of a REM cycle is far better than starting another you cannot finish.
90% of the time I will wake up before the alarm and will sleep the same amount of time over the weekends, when I usually don't go to bed as early as I do during the working part of the week. The thing that I constantly think about is - could I benefit from those 2 extra hours to get to that magic number 8? I would really like to try it, but I keep waking up after 6 hrs. :)
I've started to think it's because of not so healthy lifestile - no exerxice, sub optimal diet, irregular bed time. Is it possible that my poor lifestyle results in me waking up after only 6 hrs of sleep and while feeling OK (it became normal to me), I could feel better if I slept longer? That was always something I pondered about. How to know if you really are a short sleeper, or you're just a person that gets by with sleeping less than recommended while not feeling as good as they could if they slept longer?
