The Thermalist® Journal

The oldest human practice. The newest science that proves why it works.

Your body knows how to recover. Modern life just never lets it finish.

We’re built to move through cycles — stress and recovery, heat and cold, wake and deep sleep — and each one is designed to complete itself. We rarely let it. We trigger the stress response and leave it open. We live under artificial light, eat off rhythm, and sleep in pieces. The cost shows up as dysregulated metabolism, a nervous system stuck in high gear, and a kind of depletion most people can’t name.

This is where I write about the other half of the cycle.

I’m Dr. Susanna Søberg, metabolic scientist and the researcher behind the Søberg Principle (Cell Metabolism, Cell Reports Medicine). I study how cold, heat, breath, sleep, light, movement, and food regulate metabolism and the nervous system — and how to use them precisely so the body can finish what it starts.

What you’ll get: the mechanisms, the protocols, and 80+ articles plus exclusive podcast content. No hype. Just the science and what to do with it.
