“You can take a human out of being in nature, but you can’t take nature out of the human being” This is the statement I pose to Dr Leo right at the beginning of our chat today, and I think it encapsulates the essence of our conversation.

Today we’re going to discuss the comfort crisis and the importance of ‘ancient stressors’ to support modern health.

To give some context to this discussion, it seems like we’ve made life easier than ever. Meals on demand, warmth at the press of a button, and barely a reason to move. But this relentless convenience could be silently eroding our health. In this episode, we ask the provocative question: Has modern comfort become our newest disease?

In other words, our biology still expects challenge. When we remove all friction from daily life, we also remove the very triggers that kept us metabolically flexible, mentally sharp, and emotionally resilient.

From fasting and thirst to cold plunges and plant toxins, we explore the science of intermittent living, the idea that reintroducing short bursts of ancient stressors might act like a vaccine against the chronic diseases of modern life.

We unpack:

Why stress isn’t always the enemy but a tool, when used wisely
How ancient triggers like hunger, cold, and heat can reboot resilience
What it means to recover well, and how purpose, stillness, and nature complete the cycle
Whether biomarkers like CRP or HRV really change with these practices
How to start your own intermittent living journey safely and simply
