Cold Water Immersion: 👇
Cold hits the carotid sinus
Receptors in your neck sense the sudden drop in skin temperature and send an alert straight to the vagus nerve.
Dive-reflex kicks in
Your body thinks you’re plunging underwater. Heart rate slows, blood pressure stabilises, and parasympathetic “rest-and-digest” mode takes over.
HRV boost = calm mind
Increased vagal tone shows up as higher Heart-Rate Variability, a proven marker of lower stress, better focus, and faster recovery.
Anti-inflammatory ripple
Vagal activation releases acetylcholine, taming systemic inflammation and supporting immunity.
How to try it
Submerge to the collarbones for 2–3 minutes
Breathe slowly through the nose (4-second in, 6-second out)
Step out, warm up, and let your body do this naturally.
