Canon
•
Søberg's cold exposure protocol functions like a natural dopamine reset — it elevates baseline dopamine without the crash cycle that substances create. For people in recovery, cold exposure provides the neurochemical lift that substances used to provide.
Highlights
•
Cold exposure produces a sustained dopamine increase of 250%
Søberg's research: deliberate cold water immersion (11 minutes per week, distributed across sessions) increases norepinephrine 530% and dopamine 250% — and unlike caffeine or drugs, the dopamine increase is sustained for hours, not followed by a crash.Was this useful?
