Mechanism
Inflammation, IL-10 and the Cytokines
IL-10 up. TNF-α, IL-6, IL-8 down.
What it is
The system, explained.
Cytokines are the immune system's messengers. Pro-inflammatory ones cause fever and sickness; IL-10 dampens them.
Breath
What the breath does to it.
After endotoxin, trained practitioners showed higher IL-10 and lower pro-inflammatory cytokines — driven by the breathing.
Cold
What the cold does to it.
Cold alone did not significantly reduce inflammation in the component study.

What is still unknown.
Chronic disease outcomes; long-term effects.
Feel it.
The mechanism is measurable; the experience is immediate. Three breaths.
Never in or near waterWim Hof Method breathing, when done intensely for multiple rounds, can in rare cases lead to loss of consciousness. Always practice seated or lying down, in a neutral space such as a living room — never in water, in the shower, while driving, or operating machinery. Read the safety doctrine.
