COLD PLUNGE & CONTRAST THERAPY GUIDE
Cold plunge and contrast therapy harness controlled temperature exposure to activate the body’s recovery and adaptive systems. The Air Relax CoreChill XL allows water to be cooled as low as 3°C or warmed up to 42°C — ideal for both cold-only and hot–cold contrast protocols. Cold immersion triggers vasoconstriction, reduces inflammation, and boosts endorphins, while alternating with heat enhances circulation, detoxification, and lymphatic flow. Ozone purification ensures ultra-clean water for every session.
