Surprisingly little alcohol can affect heart rate variability

The 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.

I am fortunate enough to live in a country where we only had a lockdown for about 4 weeks of 2020, and during that time I didn't drink. See if you can see from my sleeping heart rate when that was: https://i.imgur.com/7VlYQ67.png

They 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 [0] https://academic.oup.com/ageing/article/49/3/3…

That seems like a non sequitur ("The optimal level of alcohol intake for health and longevity is zero"). All I see in the article you referred (or the original article above) are several (valid) questions about the J shaped association, like confounding factors and survival bias. But these aren't evidence that the optimal level is zero. Merely challenging/speculating about the opposite view is not evidence. Also, as…

Epidemiology strikes again! I watch a lot of videos on nutrition and researchers often say that randomized control trials are too expensive so we need to rely on epidemiology despite its flaws. What I find crazy is that nations around the world collaborate and spend billions of dollars building a particle accelerator and yet we can't seem to find money to research something that affects every human every day of their…

I guess that is because particles in the accelerator are not alive, so you can accelerate anyway you want. Do you really want to round up a group of seniors and gives them different doses of alcohol and see how much you can accelerate their demise?

You appear to be demonstrating the opposite of what is claimed here: your heart-rate variability seems to have decreased when you were not drinking alcohol. When I went back to the article to check this, however, I saw that, while the text says that alchohol has "a negative effect on HRV", and their model explains this, the diagram shows alcohol increasing the HRV. As the text's version of the observed results and it…

The link doesn't refute the J-shaped curve, but rather that small to moderate amount of alcohol has health benefits . "Therefore, although there is a strong body of evidence that shows a J-shaped association between alcohol intake and mortality, it seems likely that the link between low–moderate intake and improved survival is not causal, and there is no ‘safe’ threshold intake below which drinking gives benefit. How…
