The Research Behind the Søberg Principle & Thermalist® Method
In 2021 Dr. Søberg published peer-reviewed research in Cell Reports Medicine confirming that structured contrast therapy — alternating cold and heat exposure, ending with cold — activates brown adipose tissue and produces measurable metabolic outcomes. This research became the scientific foundation for the Søberg Principle, now adopted by millions worldwide.
Her work has been featured on Huberman Lab and discussed by Andrew Huberman and Joe Rogan on The Joe Rogan Experience, featured in The New York Times, The Times, The Guardian, and BBC Radio, and applied in wellness settings across 25+ countries.
