The Polar Plunge Do the Wim Hof cycle of thirty breaths while still on dry land, or in shower after completing necessary hygiene. Prepare an ice bath, or jump in water as cold as you can find. Set a timer for two minutes, or start playing a song that is two minutes long. Continue Wim Hof breathing until you can breathe calmly and normally (remember, the cold will make you want to gasp for air). Exhale fully, and hold your breath at the bottom.
