Welcome to the Commune podcast. My name is Jeff Krasno.

So today's episode is an exploration into what I call an evolutionary mismatch.

So the basic idea here is that human genes evolved over hundreds of

thousands of years and are very slow to change, but our lifestyles have altered drastically.

Especially in the last 150 years, our lives have been engineered for comfort and convenience.

And this is ironically leading to a lot of discomfort and inconvenience.

In short, our culture is hijacking our biology.

And many of our adaptive mechanisms have been turned against us. So today's episode focuses on one aspect

of this trend, thermoneutrality. So before modern heating systems and cooling technologies,

humans relied on their body's internal thermostat, but today's constant controlled environments prevent natural metabolic processes

such as thermogenesis, the production of heat in the body, and perspiration, leading to a lower

metabolic rate and decreased overall resilience. Today on the show, I'm joined by a commune co-founder and long-time

friend and frequent visitor here to the podcast, Jacob Laub. And together we discuss

thermal adaptivity, the body's ability to naturally adjust to temperature. Jake and I discuss the importance of counteracting

the negative effects of modern comforts like thermo neutrality, in this case allowing the body

to experience temperature fluctuation and encourage the body to engage its natural regulatory

mechanisms.

Together we share practical applications to counteract our culture's penchant for occupying

a perennial comfort zone, like varying room temperatures, turning the heat off, wearing less clothing,

and yes, the horrid, cold plunge. Before we dive in,

I'm thrilled to announce my new commune course titled Good Stress. In my course, I share

10 good stress protocols that helped me lose 50 pounds, reverse my prediabetes, improve my sleep,
