Summary
Dr. Susanna Søberg discusses her research on cold and heat exposure protocols, including the "Søberg Principle" of ending on cold to maximize metabolic benefits. She covers brown fat activation and practical implementation.
Key Points
- End on cold to force body to reheat itself (increases metabolism)
- Brown fat is activated by cold exposure
- Combining sauna and cold exposure amplifies benefits
- 11 minutes cold / 57 minutes heat per week minimum
- Winter swimmers show increased brown fat activity
- Consistency matters more than intensity
