Ingestion in rats given limited daily access to water of 12°, 24°, and 37°C is a positive function of water temperature, even though ingestion of warm water decreases blood osmotic concentration faster than cold water. The paradox suggests that temperature-dependent gastric factors and water-transport factors determine stomach distention cues of thirst satiation.
