Dr. Susanna Soberg's Soberg Principle states that to maximize the benefits of cold exposure, one needs to reheat naturally after a cold shower, ice bath or cold water immersion. Combining caffeine ingestion 60 to 120 minutes before the deliberate cold exposure can further supplement dopamine receptors and epinephrine levels, without compromising other aspects of daily life.
This podcast recommends a combined protocol for increasing dopamine levels involving caffeine ingestion before deliberate cold exposure. Additionally, the podcast touches on how cold exposure can transform white fat into beige or brown fat and result in long-lasting metabolism increases.
The Soberg principle recommends that to achieve maximum benefits from deliberate cold exposure, one should allow their body to reheat on its own after a session, rather than jumping into a hot shower or sauna immediately. Alternating cold water immersion with exposure to cool air can help achieve this effect.
