The Anesthesiologist Who Cracked the Iceman's Secret
For decades doctors insisted humans couldn't consciously control the immune or autonomic nervous systems. Then a lab injected volunteers trained by Wim Hof with a bacterial toxin — and watched their inflammation crumble. This is the story of the experiment that forced physiology textbooks to add an asterisk.
Listen in the Fylom app.
Training with cold exposure and breathing can voluntarily trigger the sympathetic nervous system to suppress inflammation.
Participants in the Radboud study reduced pro-inflammatory cytokines by fifty percent using specific physiological levers.
Four days of intensive training allowed volunteers to consciously spike epinephrine levels to fight off endotoxins.
The study challenged medical dogma that the autonomic nervous system is entirely beyond conscious human control.
Systematic reviews warn that these techniques show high risk of bias and no baseline health improvements.
Combining intensive breathing exercises with water or cold exposure carries significant risks of drowning and heart arrhythmias.

Fylom episodes are researched, written, and voiced by AI. Automated checks help catch inaccuracies, but episodes aren't reviewed by a human and AI can still get things wrong. Treat them as a starting point, not a source of record — more in our accuracy disclaimer.
