#102: "The Iceman," Wim Hof

WARNING: AS I’VE EMPHASIZED BEFORE, NEVER DO BREATHING EXERCISES IN WATER OR BEFORE TRAINING IN WATER. SHALLOW-WATER BLACKOUTS CAN BE FATAL. Wim Hof (@Iceman_hof) is a Dutch world record holder, adventurer and daredevil, commonly nicknamed “The Iceman" for his ability to withstand extreme cold. He is the creator of the Wim Hof Method and holds more than 20 world records. Wim is an outlier of outliers, as he routinely asks scientists to scrutinize and validate his feats. Here are just a few examples: In 2007, he climbed past the “death zone" altitude on Mount Everest (~7,500 meters) wearing nothing but shorts. In 2009, Hof completed a full marathon above the polar circle in Finland, in temperatures close to −20 °C (−4 °F). Dressed in nothing but shorts, Hof finished in 5 hours and 25 minutes. Hof holds the current Guinness World Record for the longest ice bath, now set at 1 hour 53 minutes and 12 seconds. But it’s not just cold. In 2011, he ran a full marathon in the Namib Desert without water. The run was performed under the supervision of Dr. Thijs Eijsvogels. He can also run at altitude without suffering from altitude sickness. In the same year, he was injected with toxins under doctor supervision and demonstrated that he could effectively control his autonomic immune response. Wim was able to raise his cortisol levels and lower his blood concentrations of cytokines (inflammatory mediators) using solely his meditation and prep techniques. Not only this, but he was able to train others to achieve the same effect… with only 4 days of training! We dig into all this and more. I loved this conversation and hope you do, too...

I have two to recommend right off the bat: The Graveyard Book by Neil Gaiman – Perhaps my favorite audiobook of all time. Vagabonding by Rolf Potts – This book had a huge impact on my life and formed the basis for a lot of what has become The 4-Hour Workweek To get your free audiobook and a free 30-day trial, go to Audible.com/Tim.

This podcast is also brought to you by MeUndies. Have you ever wanted to be as powerful as a mullet-wearing ninja from the 1980’s, or as sleek as a black panther in the Amazon? Of course you have, and that’s where MeUndies comes in. I’ve spent the last 2-3 weeks wearing underwear from these guys 24/7, and they are the most comfortable and colorful underwear I’ve ever owned. Their materials are 2x softer than cotton, as evaluated using the Kawabata method. Check out MeUndies.com/Tim to see my current faves (some are awesomely ridiculous) and, while you’re at it, don’t miss lots of hot ladies wearing MeUndies. *** If you enjoy the podcast, would you please consider leaving a short review on Apple Podcasts/iTunes? It takes less than 60 seconds, and it really makes a difference in helping to convince hard-to-get guests.
