About this listen
We’ve all heard the story.Serotonin: the “happiness chemical.”Too little, and you’re depressed.Boost it, and you’re back to normal.
It’s a neat narrative. Comforting.But like most comforting stories, it’s incomplete.
In this episode, we explore serotonin not as a single note of happiness, but as the tuning fork of the brain. A molecule that doesn’t just adjust volume: it sets rhythm, balance, and resonance.
Far from being about “mood” alone, serotonin touches almost everything: sleep, appetite, memory, social bonds, even the fragile architecture of the ego itself. And the most surprising part? Over 90% of it isn’t even in your brain.
🔎 In this episode, we cover:
* Why serotonin is more than the “happiness chemical”
* How it shapes perception, rhythm, and sense of self
* The gut–brain connection and where most serotonin is really found
* Why this molecule is central to both everyday experience and psychedelic journeys
Serotonin isn’t just a switch for happiness. It’s a hidden system of tuning, weaving context into consciousness.
