About this episode

This episode explores how your inner world and body influence the brains of those around you.

Welcome back to Build Your Best Brain — where neuroscience meets real life, and where you learn how to actually use your brain to feel better, think clearer, and live more intentionally. This month, we're dismantling the idea that we're powerless to our environment. We're exploring the inside-out brain — how your inner world shapes the outer one — and today, we're taking it a step further by looking at how your body influences the brains of the people around you. Here's what we're getting into today: • A real example of how my body state completely changed how people responded to the same behavior • What happens in the brain when we read someone's posture, tone, or facial expressions • How to use small shifts in your own body to influence your environment in a healthy, grounded way If something in this episode hits home, message me — I love hearing your reflections. And if you want deeper support, make sure you're on my email list for access to free weekly webinars where we unpack your questions live. And in the next episode, we'll dive even deeper into how to integrate this science into your day-to-day life so these concepts actually change how you feel. Want to Go Deeper? Join…
