About this evidence tier
This is a provisional editorial rating for the general practice, not proof that it treats a condition. Research citations will be attached after source-level review. Use the safety notes and judge the practice by your own tracked response.
A short cold immersion or shower triggers a controlled stress response: breath deepens, dopamine rises, and mood often lifts for hours. Start with thirty seconds and build slowly.
