Breathwork Safety in Extreme Temperatures
Controlled breathing helps manage the shock of cold immersion and the intensity of high heat. Here is how to practice safely.
Box breathing in the cold plunge
Entering 45°F water triggers a gasping reflex. By focusing on a 4-second inhale, 4-second hold, 4-second exhale, and 4-second hold, you force the parasympathetic nervous system to take control.
Avoiding hyperventilation
Never practice breath-holding (Wim Hof style) while inside a water tub or in a high-heat sauna. Extreme temperatures can cause lightheadedness; always prioritize regular, deep nasal breathing.
