The Iceman is back.

Wim Hof is a Dutch world record holder, adventurer and daredevil, nicknamed “the Iceman” for his ability to withstand extreme cold. He holds twenty world records – including a world record for longest ice bath, and has stayed immersed in ice for as long as 1 hour and 52 minutes and 42 seconds. In 2007, Wim attempted, but failed (due to a foot injury), to climb Mount Everest wearing nothing but shorts. Then, in 2009, he reached the top of Mount Kilimanjaro in his shorts within two days. In 2009, Wim also completed a full marathon above the polar circle in Finland, in temperatures close to −20 °C (−4 °F) – dressed in nothing but shorts. He finished the marathon in 5 hours and 25 minutes. In  2011, Hof also ran a full marathon in the Namib Desert without water.  And in this most Vice video Wim demonstrates how he can consciously alter his immune system activity using a combination of breathing and cold. So how does the Iceman do it? I

n my previous episode with Wim, "Conquer The Cold And Get Quantum Leaps In Performance In This Exclusive Interview With The Amazing Iceman Wim Hof", you discovered many of his secrets, including: -How Wim uses the science of breathing to control his body temperature and resistance to the cold… -Wim’s breathing technique fully explained... -a recent study of the influence of concentration/meditation on autonomic nervous system activity and the innate immune response... -Wim’s book: “Becoming The Iceman" and the book “Breathology"... -Wim’s meditation technique… -How Wi ran full marathon in the desert with no water… -Whether cold thermogenesis give some kind of adaptation to perform better in heat… -Why cold doesn’t really make you sick, and the true effects on the immune system… -Why Wim took a group of thrombosis patients into the icy Sweden wilderness… -How you can learn Wim’s secret techniques from the Iceman himself… -And much more.

Now, in today’s audio episode, Wim and I delve into even more of his tips, tricks and biohacks to conquer the cold and get quantum leaps in performance, and you'll discover even more, including: -How Wim got started with cold exposure... -How Wim's breathing techniques can be used to withstand not just extremes of cold, but also extremes of heat and other forms of stress... -Whether Wim gets cold skin burns... -The details of Wim's groundbreaking new study "Voluntary activation of the sympathetic nervous system and attenuation of the innate immune response in humans"... -What Wim thinks about popular cold thermogenesis gear, like ice vests and cooling pants... -What kind of workouts Wim does, including extreme isometrics and cold yoga... -Why Wim only eats once per day...
