Welcome back to the Flex Diet Podcast. I'm Dr. Mike T. Nelson, and today I’m diving into the frigid but fascinating world of cold water immersion with Dr. Thomas P. Seeger — a true pioneer in sustainable engineering and a leading voice on cold exposure.

We break down the latest science behind cold plunges, including how they impact brown fat, metabolism, HRV, testosterone and overall resilience. Tom also shares key takeaways from his excellent book Uncommon Cold, and gives us a peek into the thinking behind his company, Morozko Forge — makers of some seriously high-tech cold tubs.

We even get into my own experiences with cold immersion, what’s hype and what’s helpful, and how to safely integrate it into your routine for health and performance gains.
