CO₂ water immersion shifts the nervous system toward a calmer, rest-and-recover state
CO2 water immersion activates parasympathetic nerve activity in humans, as demonstrated by spectral analysis of R-R electrocardiogram intervals showing increased high frequency amplitude and decreased LF/HF ratio during CO2 foot bathing.
What this means for you
When your nervous system tips toward its rest-and-recover mode, your heart rate settles, tension eases, and your body gets better at repairing itself. This kind of shift is what most people feel as a deep, almost effortless calm — the kind that's hard to manufacture through willpower alone.
