Meditation itself was 'mindfulness', some of it was guided, most of it was not, guided meditation was once a week (I'm not counting the yoga, which was also meditative), I spent 5 minutes in the morning, 5 minutes at lunch, 15 minutes when I got home and 5 minutes before bed. (and I'm pretty well disciplined so I stuck to that routine).
The reason I say I've tried everything is because I've seem therapists/psychologists and taken their recommendations on board, I've researched and taken more information on board and this is not the first thread where "night owl" information has come up, and I took information from there too. And, like I said, I'm rigorously self-disciplined; so I'm able to stick to things... But, I will happily take your advice on board and try that. Since I don't care about whinging, I care about results.
I use an Oura ring for this but I bet there are cheaper methods, perhaps with a heart rate chest strap, though there's an additional bonus with the ring in that it tracks sleep phases as well.*
*to some degree of accuracy (~66%?) I use it directionally only since the values have big error bars.
I'm surprised to hear this, although I'm glad it works for you.
I wear an Apple Watch Series 3 night and day, which reports HRV. I've found it to be pretty difficult to draw conclusions from since the measurement stays pretty much the same even when significantly changing lifestyle/habits. Over the past year I have went pure vegan (went down 15% body weight), went from exercising 0 days a week to 6x 1 hour high intensity, went from chronically sleep deprived to 7-8 hours / night, and HRV has been exactly the same.
Perhaps the accuracy of the apple watch isn't so great compared to what you're using. My measurement tends to fluctuate between 25ms - 40ms throughout the month with an average of 30ms over the entire month for the past year, despite the dramatic lifestyle changes mentioned above.
I've noticed Apple Watch's VO2 max measurements are also -very- unreliable. Mine has decreased 25% in the past year despite being at a dramatically higher cardio fitness level.
Curious if anyone else with an Apple Watch has had a similar experience with these measurements. I really like the idea of using them as a feedback loop, which is partly why I wear an apple watch to begin with, but hasn't quite panned out.
I've seen my average vary from 10-50 and HRV max from 50-140 depending on sickness, exercise routine, hydration, drug use, etc. The quality of that average is interesting to observe as well, ie two nights' average of 40 can look very different depending on the peaks and valleys.
It is challenging though to suss out what effects various things have. It requires a whole lot of normality in my lifestyle so as to limit the number of variables as best I can.
EDIT: the one I use is paid on Glo.com. Found a free one that seems similar https://youtu.be/F0jwdoSWsio

Saying you did "meditation" for a year doesn't tell us much, just the same as you saying you "exercised" for 4.5 hours a week doesn't tell us much. Both of those terms can mean a great number of things qualitatively speaking.
Counter-intuitively you could warm yourself 1-2 hours before bed with a hot bath or sauna session. This triggers the body to bring blood closer to the surface and extremities to shed heat, in effect "helping" the body cool itself as it approaches bedtime.
Based on these observations I think maybe you haven't tried "absolutely positively everything". And even with all the environmental and body things you've tried, the mental aspect cannot be understated.
EDIT: based on some of the replies about temperature. The hot bath method because it will help your body cool in a physiological way while a cold bath will do the opposite. A cool environment will do the same while a hot one will do the opposite. So hot bath 1-2 hours before bed and lower the room temp for the best of both worlds. Some people go further with chilled blankets such as the Ooler.
