Abstract
The core temperature triggering thermoregulatory action defines the threshold for that response. Elevated core temperatures trigger sweating and active pre-capillary vasodilation whereas progressively lower temperatures trigger arterio-venous shunt vasoconstriction and shivering. Temperatures between the sweating and vasoconstriction thresholds, which do not trigger thermoregulatory responses, identify the interthreshold range (1).
