#309 The hidden link between light exposure and gut health revealed! In this episode, I explore the fascinating connection between circadian rhythms, light exposure, and digestive health with regenerative health expert Dr. Max Gulhane.

Unfortunately, we experienced a technical issue during recording, so I'll be walking through the first half of our conversation from my prepared notes before we dive into the recorded interview with Max.

In this episode, you'll discover:

✅ Why light exposure is more than just vitamin D for gut health

✅ The gut microbiome's circadian rhythm and how 15-20% of bacteria fluctuate in a 24-hour cycle

✅ How light signals affect your gut barrier, permeability, and immune function

✅ The SCFA-circadian feedback loop and why it matters for healing

✅ Why midnight phone scrolling disrupts your gut (and what happens when you do)

✅ The role of melatonin produced in your gut (not your brain)

✅ How to optimize light exposure for gut health—safely for Australian conditions

✅ Why fixing circadian disruption might be the missing piece in your gut healing protocol
