Evidence synthesis
In the same controlled study, one-hour immersion at 14 °C produced measurable increases in plasma dopamine levels.
Limitations
One small study. The dopamine response was measured via plasma assay during water immersion — not dry cold and not a direct measure of central dopamine signaling.
