Cold water immersion went from niche ritual to wellness status symbol in about five years. But what does putting your body in an ice bath actually accomplish?

In this episode, Jeff weighs cold plunge benefits with enthusiasm and skepticism both fully switched on, from the catecholamine surge to brown fat to the Wim Hof method.

The cold shock response, the dopamine surge, and why cortisol drops
Brown fat, metabolism, and the truth about cold for fat loss
The Wim Hof method and what the famous immune study really showed
Why a plunge right after lifting can blunt muscle growth
How cold affects women's bodies differently, from the Haenyeo divers to estrogen and iron
Who should never plunge without medical clearance

This episode is for anyone curious about cold plunge benefits, weighing an ice bath habit, or trying to tell the practice apart from the pitch.
