One other (unrelated) thing:

Since Wim-Hof is able to maintain core-body temperature during cold exposure through his breathing exercise, doesn’t that mean he misses out on the beneficial effects of cold-water immersion?

But how do I know what dosage to take? I bought a brand supplying Lactobacillus Rhamnosus based on a comment Dr. Rhonda made on an older Joe Rogan podcast about its effect on GABA and anxiety. But I looked up the study, and if it’s the one she’s referring to, it was done on mice. So I’ve no idea how to replicate that study in a human (me). Anyone have insight on this, or even a reference to a podcast where she discusses dosages for probiotics in humans? Much appreciated!
