[Ep 222] Timing, Circadian Biology & Environmental Coherence | Avi Jacobson

How much of our health and terrain is shaped not just by what we eat or how we avoid toxins, but by the timing of our activities and choices? The when of our lives.  

In this episode, we sit down with Avi Jacobson, co-founder of Kintsyougi and one of the creators of the CRD Challenge—a simple three-week experiment that introduced thousands of people to the principles of circadian biology. Built around practices like morning sunlight, reducing artificial light after dark, eating with daylight, and reconnecting with our natural environment, the challenge became a thriving community before ultimately being entrusted to the Institute of Applied Quantum Biology.

Avi shares his own journey from chronic health struggles and functional medicine to terrain and circadian biology, explaining why he believes many of the chronic symptoms people experience today are rooted in environmental incoherences rather than isolated diagnoses. Throughout the conversation, we explore why light may be one of the most overlooked inputs affecting human health, how timing influences metabolism and energy, why the body responds differently to the same meal depending on the time of day, and how small shifts in our relationship with sunrise, sunset, and artificial light can create profound changes over time.

Perhaps most refreshing is Avi's approach to learning itself. Rather than asking people to accept new ideas on faith, he encourages curiosity, observation, and personal experimentation...using your own body as the ultimate proving ground.
