Cold Plunge

Shop on Amazon

A cold-water immersion setup such as a plunge pool, cold tub, or ice bath used for deliberate cold exposure. The common protocol is a brief immersion in very cold water, often early in the day and done safely, to trigger a strong adrenaline/noradrenaline response and a dopamine boost. People use it for alertness, stress resilience, and sometimes soreness or recovery support, though it may not be ideal immediately after training if maximizing muscle growth is the goal.
