What cold plunging actually does
Cold water immersion triggers vasoconstriction, a spike in norepinephrine, and a controlled stress response that many users report improves alertness, mood, and recovery.
Consistency matters more than extremes — a few minutes at 45-50°F several times a week is plenty for most people.
Chiller vs. ice
A built-in chiller (like the Glacier's 1HP unit) holds a precise temperature on demand, eliminating ice runs and inconsistent sessions.
Pair it with ozone + UV-C filtration so the water stays clean for weeks rather than days.
