In this episode of One Thirty Biohacks, we sit down with Katherine Estess to explore how the nervous system and trauma shape our health, our relationships, and the way we experience the world.

We talk about what “trauma” means in modern trauma research (far beyond major events), how different nervous system states influence everything from emotional regulation to chronic stress patterns, and why so many symptoms make more sense when you look through a nervous system lens.

Katherine brings a rare blend of academic depth and practical tools. She is currently completing a Master’s degree in Psychology at the University of Copenhagen, is a certified hypnotherapist, and has trained in Somatic Experiencing (evidence-based trauma therapy) and polyvagal theory. She has also done neuroscience research, including brain measurements related to emotions and states of consciousness such as meditation and hypnosis, including work at the University of California, Santa Barbara.

We also explore Katherine’s perspective shaped by her travels — including time spent with Pacific tribal communities and experiences from visiting 68+ countries — and how different cultures relate to connection, regulation, and community compared to the Western world.

If you’ve been curious about nervous system work, trauma-informed health, or how to create more stability and capacity in a demanding world, this conversation offers both clarity and perspective.
