#2The article briefly mentions RHR (resting heart rate) also. Anecdotally of course, but I notice my RHR being ~5 - 8 bpm lower when I abstain from alcohol for a few days.

#3They close with this:
However, a more critical review[0] of the epidemiological data that took into account genetic variants which impact the effect of alcohol intake on longevity shows that the described J-shaped relationship is not as robust as once thought. In conclusion the review simply states:
The optimal level of alcohol intake for health and longevity is zero

Great example of the hazards of trying to infer causation from epidemiological datasets.

#5> A healthy HRV reflects a healthy balance between sympathetic and parasympathetic stimulation.
How do you know this?

n = 1, but using my oura ring, I can see a diff of 10% higher RHR pmb during my sleep when drinking a single glass of beer after diner.
It surprised me a lot.

I have worn a Garmin watch with HR monitor for months at a time off and on for the last few years.
My resting heart rate while sleeping is typically 64-68 without alcohol and 65-85 after drinking several glasses of wine. There is such a marked difference in RHR in the two scenarios that you could tell if I drank simply by looking at my heart rate chart during the night.
Interestingly, I attempted to start running for one month about a year ago. My endurance is poor, but I would run/walk for several kilometers. Within the first week and continuing through that month, my RHR while sleeping was 52-62. Not only was it significantly lower, it took a long time after stopping exercise for the rate to return to what it usually is.
I don't know what this all really means, but it is fascinating. Studies or not, I imagine that not drinking + regular cardio exercise is better for long life than the alternative combinations.

Since we're talking anecdata anyway, it could be from decreased sleep quality instead of direct causation.

Elite athletes have RHR in the 40s. Exercise improves the heart.

#10People can test this for themselves with a common fitness tracker.
The Apple Watch records this data.
Anecdotally, 1.5 drinks within 5 hours of going to sleep raises resting heart rate by 5%-10%. My friends who have an Apple Watch have similar results.
My personal data on HRV and booze is too erratic to draw conclusions.
