"The Thermalist Method gave me a science-based understanding of how contrast therapy—moving between cold and heat—builds resilience and boosts metabolism. It had a big impact on my well-being, and I’m excited to share it with others seeking connection and vitality."

About Me

I’ve spent my career as a researcher in developmental psychology, exploring how the brain develops and connects. I poured myself into my work and family with full intensity, until… I burned out.

In my journey, I turned to many things: therapy, meditation, physical movement, long conversations, quiet reflection. With a lifelong love of sports and a deep belief in the power of a healthy lifestyle, I had always relied on my body as an anchor. But this time, I needed something more.

One freezing January morning, a friend invited me to join along to swim in the North Sea, and I said yes without knowing what I was signing up for. The shock of icy water stole my breath, and the shivering lasted longer than it felt like it should. But then came something unexpected—a rush of energy and sharp clarity that stayed with me long after. Over time, the cold sea quietly lifted my mood in ways I hadn’t imagined.

As a scientist at heart, I needed to understand why. That curiosity led me to Dr. Susanna Søberg’s Thermalist Instructor program—a science-based approach to cold and heat exposure that gave me the tools to make sense of what I’d experienced. Now, I combine my academic background with lived experience to help others explore contrast therapy in a safe, informed, and meaningful way. Whether you’re seeking better stress regulation, mental clarity, a way to reconnect with your body, or simply a new experience, I’m here to share what I’ve learned—so you can discover your own version of balance.

Join me for a Thermalist Method® Workshop, a powerful and science-backed experience combining cold and heat exposure with guided breathwork and mindfulness — designed to support your mental clarity, stress relief, immune system, and physical recovery.

This isn’t just another wellness trend. It’s a method rooted in over a decade of scientific research by Dr. Susanna Søberg, PhD in metabolism and pioneer of the Søberg Principle — now practiced by thousands worldwide.
