Evidence synthesis
Controlled immersion work measured pronounced initial cardiorespiratory responses, and broader review evidence shows acute cardiovascular and autonomic changes across water immersion and cryostimulation studies.
Limitations
The magnitude is exposure dependent. Water immersion is not dry PCM contact, so this is contextual evidence rather than a prediction of an Ice Sack session.
