The Science and Practice of Cold & heat therapy
A Proven Method. Practiced with Precision.
The Thermalist Method® is a science-based contrast therapy method built on four pillars: cold exposure, heat exposure, breathwork, and meditation. Together, they form a structured system designed to support metabolic health, nervous system regulation, and long-term physiological adaptation.
The method is grounded in human physiology and based on the scientific work of Dr. Susanna Søberg, metabolic scientist and one of the world’s leading researchers in contrast therapy. When applied as a method rather than as isolated cold or heat exposure, people consistently experience a deeper sense of regulation, resilience, and recovery.
The Thermalist Method® is designed to be returned to. Through repetition, the body learns to respond more efficiently to stress and recovery, while the nervous system gains clarity and balance, supported by structured breathwork and meditation.
Today, the method is delivered globally by more than 200 Certified Thermalist® Instructors across 25+ countries, ensuring consistency, safety, and scientific integrity wherever it is practiced.
The Thermalist Method® is practiced exclusively by Certified Thermalist® Instructors in contrast therapy studios and delivered in accordance with official methodology and brand standards to ensure safety, quality, and consistency.
