Deliberate Cold Exposure (DCE) might change your life. It changed mine.
CORRECTION: Scott Carney didn't conduct the experiments. He reported on the results. The experiments were designed and conducted by medical research professionals. You can read more in Carney's book 'What Doesn't Kill us' available here http://www.scottcarney.com/what-doesn....
Thomas P Seager earned his PhD in civil engineering back in 2001. It wasn't until about 15 years later that he turned his scientific training on himself, and began a journey of self improvement and discovery that led to the creation of Morozko Forge. Along the way, he lost over 50 lbs, increased his testosterone to abnormally high levels, and improved his stress tolerance. One of the critical aspects of his transformation has been regular practice of deliberate cold exposure in a freezing ice bath.
