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.
