Wim Hof: Ice Ice, Maybe? Doctor examines

Doctor Dissects the Wim Hof Method: Cold Hard Scientific Analysis
How to burn off the fat with cold, breathing
I'm a cardiologist and academic, and this is an overly detailed look at the Wim Hof Method. (Wim Hof is a Westerner who uses yogic techniques to achieve the previously impossible, enduring cold by modifying his breathing using pranayama).

For those who might ask... Yes, I've tried the technique, quite extensively. But I haven't shared those experiences, as they're not relevant to an attempt at an unbiased scientific appraisal.

"If It Ducks Like a Quack" is a series where I seek to find the truth (if any) behind high profile medical claims, while attempting to teach critical analysis of scientific statistics.

Thank you to Scott Carney. If you enjoy this channel, you'll love his audio-book: scottcarney.com/audible (youtube.com/user/sgcarney).
