Related to diet, I read in one article that heavier meals high in saturated or trans fats and high glycemic carbohydrates have been found to reduce heart rate variability, in contrast with a Mediterranean diet and lighter meals high in omega-3 fatty acids, B-vitamins, and probiotics. I have also found that my HRV goes up a little if I remember to drink a lot of water.
My HRV has been chronically low since 2020 at least--that's when I first identified it. I've played around with many modifiable factors in an effort to influence it, yet, it stays steady year over year, and it's actually declining. For my age, it should be about 40-60ms and mine is about 16-17.
