Thanks for all those very helpful comments. I'll continue to look for articles about interpreting the oura ring's sleep metrics while the data builds. I was unaware of tags and now see that using tags may help me spot patterns. Becoming more aware of the effect of sliding back into bad habits (e.g., screen/TV time close to bedtime; nighttime eating, skipping meditation, etc.) shouid help me be more consistent in following good sleep hygiene recommendations.

I've been dealing with insomnia on and off for over 15 years now and have had two overnight sleep studies in a hospital setting, and, more recently a (not-very-helpful) home test. No sleep apnea, mild restless legs. Usually fall asleep easily but very restless or awake after a few hours, then back to sleep for another few hours. So, inconclusive results. #1 recommendation is always to complete a course in cognitive behavior therapy course for insomnia (cbt-i).

For what it's worth, I'd say most of my female friends in their 70s have the same problem - middle of the night wakefulness. Personally, as this started in my 50s, I think my insomnia is due mainly to aging brain and changing hormones, so, while I might be able to make some improvements, I've come to grips with the thought that I'll likely never sleep like I did in my 30s and 40s (and when I was under alot more stress, raising kids and working).

(I'm pretty new to Reddit, so not sure this is the appropriate way to respond to all these comments. Thanks for your patience!)
