In Part 2 of "Sing High, Sing Low," we dive deep into the transformative science of singing and why this ancient human practice is one of your most powerful tools for mental health, nervous system regulation, and authentic human connection. What happens when you sing? Your vagus nerve activates. Your parasympathetic nervous system (your body's built-in calm system) engages. Stress hormones like cortisol drop. Feel-good hormones like oxytocin, serotonin, dopamine, and endorphins surge. And if you're singing with others? The bonding response is measurable and immediate. Fiona, a singing facilitator and vocal advocate for reclaiming this lost practice, joins us to explore: — How singing activates vagal tone and parasympathetic nervous system regulation — Why group singing creates deeper human connection than conversation alone — The hormonal cascade of group singing: oxytocin, serotonin, dopamine, cortisol reduction — How to use your voice as your personal stress-relief and wellness tool (it's free, it's always accessible) — Voice shame, choir culture, and why so many of us stopped singing — Why singing isn't an art form —it's a fundamental human practice — Practical applications: corporate team building, community connection, personal mental health — How singing can regulate both your nervous system and the nervous systems of people around you This episode challenges the myth that only "good singers" deserve to sing and reveals how singing is your personal wellness toolkit for anxiety, stress relief, belonging, and meaningful human connection. If you've ever felt too self-conscious to sing, if you're looking for practical nervous system regulation tools, if you want to understand the science of what group singing actually does to human beings—this conversation is for you. Listen and discover why your voice has been waiting for you all long.
