Humming, singing, and chanting aren't just cultural traditions or childhood habits; they are measurable, physiological healers that your nervous system already knows how to receive.\nDr. Ana Lara shares a personal story that sparked this episode: waking up mid-sleep to find herself humming through a deeply painful sore throat — not by choice, but by instinct. What her body already knew, science confirms. In this episode she unpacks the physiology behind vocal vibration as a healing tool, including how humming increases nitric oxide production in the nasal passages up to 15-fold compared to quiet breathing, how singing integrates whole-brain function and boosts dopamine and oxytocin, and why your own voice — not music from a speaker — carries a unique internal frequency that nothing external can replicate. She also goes deeper into something most conversations miss: what we say out loud doesn't just affect others. The vibration of our words comes out of us first, and our body, nervous system, and spirit register every bit of it. This episode continues the vagus nerve conversation from last week and adds a practical, accessible layer most people have never considered.\nHumming stimulates the vagus nerve and increases nitric oxide in the nasal passages up to 15 times more than quiet breathing — improving oxygen uptake, immune function, and circulation.\nYour voice creates bone conduction vibration that travels through your skull, chest, and tissues in a way that external sound cannot — this internal feedback loop tells your nervous system it is safe.\nSinging activates multiple brain regions simultaneously — emotion, memory, and language — creating whole-brain integration and increasing dopamine and oxytocin.\nNegative words spoken aloud don't just harm others — the vibration originates in you, and your body, nervous system, and spirit absorb it first.\nSimple practices —...","thumbnail_url":"https://img.transistorcdn.com/7BlbO0DlxZ9TfxfXnOie8HzzksLgXXsUBE22ReU_fyU/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9jYzA3/ZmYwMzJjZTkyMGUx/YzIyYWQxMTE5MGQ4/Mjc3Yy5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
