Evidence synthesis
Metabolic rate increased during immersion at 14 °C and 20 °C compared to thermoneutral conditions, consistent with thermogenic defense of core temperature.
Limitations
Water immersion has different heat-transfer characteristics from dry cold. The metabolic increase magnitude depends on temperature, duration, body composition, and method.
