Extreme athlete “Iceman” Wim Hof shares his incredible story and unconventional techniques for controlling the immune response through cold exposure and breathwork. Hof, who has endured freezing temperatures that would incapacitate most people, explains how his breathing method and cold immersions “supercharge” his immune system and reduce inflammation to near-zero levels. He and Steven Bartlett discuss how these practices have helped people with autoimmune diseases and depression. Equal parts inspirational and instructional, this episode shows how pushing your body’s limits can unlock extraordinary healing potential.
