A petty correction to this excellent post: you say "Even a single serving of alcohol disproportionately impares REM sleep", but your source says "Reductions in REM sleep were observed starting at approximately 2 standard drinks".
I love this, the interday variability in my intelligence is extremely annoying.
The biggest thing for me is I don't understand how people can sleep with these watches on, it's so uncomfortable to me personally which is why the different ring technologies appeal to me more. I just wish either Garmin made one or that there was one I didn't have to buy a subscription to use.
A small curiosity: I recently learned that sleep trackers in commercial wearables are terrible for people with sleep disorders like apneas, UARS, etc. It makes sense, as this isn't a typical dataset, but it's worth knowing.
I didn't believe the stress numbers on my Garmin watch were very meaningful until I started taking Nebivolol (an atypical beta blocker) because there were so many gaps (even when I was sitting) that I didn't feel I could eyeball them or trust averages over time. Taking that drug, however, it sees far fewer gaps and I show up in the blue "rest" zone most of the time. I've been watching my heart rate a lot in the last…
Maybe it is not super accurate, but it was eye-opening for me to see how the score changes for the worse even with a little bit of alcohol. I am way more careful with when and how much I drink since I've started wearing a Fenix 6 few years back

When I started wearing a watch, it constantly distracted me and cause minor annoyance all day while I got used to it. At some point it just started blending into the background. Now, when I wear my watch on my other hand, I still have the same problem, but I don't notice my watch normally anymore. I've slept with my watch for a while (stopped because the battery is crap and I need to charge it every day or it won't l…
> I've slept with my watch for a while (stopped because the battery is crap and I need to charge it every day or it won't last past noon the next day) and I've had the same adjustment period. I'm guessing this is an Apple Watch? Garmins typically last a week or more.

I've tracked sleep using a number of devices and algorithms and I haven't found a single one that regularly aligns with what and how I feel. I know it's tracking real data, but the conclusions feel completely made up. What are other people's experience -- especially from those who are more bullish about sleep tracking?
Time in deep sleep is not a direct marker of slow-wave delta power, which is just one of the measures of repair and glymphatic flush which occurs during deep sleep.
If slow-wave activity is slightly impaired, your brain can try to make up for that reduction by increasing time in deep sleep.
However, larger impairments mean your brain will struggle to stay in deep sleep.
This is why our work at https://affectablesleep.com focuses directly on enhancing the Neural Function of Sleep (and specifically deep sleep) rather than focusing on time.
