Cold Plunge Therapy – The Science of Cold Exposure

From Ancient Rituals to Elite Performance

Cold water immersion isn’t new. Ancient Spartans, Japanese samurai, and Nordic cultures all used cold water to build resilience, stimulate circulation, and enhance mental toughness.

Today, cold plunge therapy is used by everyone from Wim Hof practitioners to professional athletes, CEOs, and wellness enthusiasts — all seeking clarity, recovery, and inner strength.

What Happens When You Take the Plunge

Cold plunge therapy activates your body’s sympathetic nervous system, triggering a hormonal response that boosts energy, focus, and circulation. At ZONE1RECOVERY, our ice-cold tubs are carefully calibrated for safe, effective cold immersion with expert guidance on breathwork and exposure timing.

Proven Benefits Include:

• Reduced inflammation and faster muscle recovery

• Sharpened mental focus and stress resilience

• Enhanced immune system response

• Better sleep and mood regulation via dopamine release

• Natural pain relief and reduced anxiety

Cold Training for the Modern Warrior

Just 2–5 minutes of controlled cold exposure per day has been linked to lower cortisol levels and higher dopamine—a hormonal state associated with discipline, drive, and clarity.

At ZONE1RECOVERY in Da Nang, our cold plunge experience is not just a trend—it's a tool for transformation.
