Cold Face Immersion (Vagus)
Cold face immersion activates the dive reflex, briefly slowing heart rate and acute stress without a full cold plunge. It is a short micro-recovery tool.
Cold face immersion triggers the dive reflex—brief cool water on cheeks and upper face can slow heart rate and calm acute stress without full plunges. Use a bowl of cool water for 15–30 seconds while breathing slowly; avoid if you have reactive airway disease.
It is a micro-tool, not chronic stress treatment.

Does cold face immersion stimulate the vagus nerve?
