Our Science Featured In
Our founder
Dr. Susanna Søberg
PhD scientist in metabolism, international bestselling author, and the founder of the Søberg Principle — the peer-reviewed scientific finding published in Cell Reports Medicine in 2021 that became the foundation of the Thermalist® Method.
Her work has been discussed by Andrew Huberman and Joe Rogan on The Joe Rogan Experience, featured in The New York Times, The Times, and The Guardian, and applied by wellness operators and practitioners in more than 25 countries.
Invited keynote speaker at FIBO, the Global Wellness Summit, and Eudēmonia Summit — speaking on the science of contrast therapy, the Thermalist® Method, and the ROI of structured recovery in premium wellness and hospitality.
Her work has reached some of the world's highest-performing athletes and business leaders.
science backed Contrast Therapy
Our work began with a fundamental scientific question:
What actually keeps humans healthy over time?
Early research focused on how the body responds to stress, temperature, and recovery.
The roots of health - the Clinical relevance
The question was explored in humans examining human brown fat activation and outcomes on metabolism with cold water immersion and sauna. Years of clinical research followed. The goal was not optimisation, but relevance and identifying outcomes that were measurable, repeatable, and meaningful for long-term health.
Scientific validation
In 2021, this work was published in a peer-reviewed scientific journal. The findings confirmed that structured contrast therapy can increase metabolic activity and reduce physiological stress with clinically relevant outcomes.
From research to system
The work continued and the scientific framework was refined, tested, and applied in real-world settings. We have built a system of programs to reduce stress which are science-based, repeatable, and adaptable to human life.
Led by experience and backed by science
Thermalist® are science backed programs built on human biology and years of scientific research. Our programs offer stress reduction and we prove how the body adapts to stress, temperature, and recovery. These are mechanisms that can be trained to support long-term health.
