Thank you.

Welcome to the My Buddy Green podcast.

I'm Jason Wachub, founder and co-CEO of My Buddy Green and your host.

What if one of the most powerful tools for your health has been hiding in plain sight?

And most of us have been actually avoiding it.

Today's guest is Bill Gifford, a veteran science journalist, author of Spring Chicken, a New York Times bestselling author on longevity and co-author of Outlive.

His latest book, Hot Wired, How the Hidden Power of Heat Makes Us Stronger, dives deep into the emerging science of heat, sweating, and what happens when we stop running from discomfort.

Bill spent his career translating cutting-edge science for real people, writing for Wired, Bloomberg, Businessweek, Scientific American, Outside, and more.

In this episode, we get into why sweating is one of humanity's greatest evolutionary superpowers and what we lose when we live in perfectly climate-controlled comfort 24-7.

We discuss the Finnish sauna tradition, what the science says about minimum effective dose, and why heat exposure may be one of the most underrated tools for cardiovascular and mental health.

We also tackle the cold punch debate.

Bill makes a compelling case for why the cold side of the equation is far less settled than what one would believe.

This one challenged some of my own assumptions, and I think it will challenge yours too.

Let's dive in.

Heat.

Sweating.

You argue that sweating, which many people do not like, is a superpower.

Let's talk about that.

What did we lose when we moved into this world of constant climate control?

And how do we get it back when we reintroduce heat?
