I've seen some clips of his interview on the Joe Rogan podcast. I didn't catch the cold bath part.

I imagine a cold bath means immersing most of your body in water. So another variant.

Theory sounds plausible. Curious if you happen to know any actual research that backs it up?

There is some research on effect of sauna on health. It seems that going to sauna is associated with lower mortality.
