Cold Plunge
The plunge — short, demanding, quietly transformative.
A cold plunge is a controlled shock with a long tail of benefit. Submersion triggers a surge of catecholamines that sharpens attention and steadies mood, and the discomfort itself is the training — each session teaches the nervous system to meet stress with stillness. Brief, deliberate, repeatable. These articles cover the protocols, the timing, and what the cold is actually doing.
