That happens because spices trigger the same neural response in the brain that activates temperature receptors, which usually respond to increased heat.
发生这种情况是因为香料在大脑中触发了与激活温度感受器相同的神经反应，而温度感受器通常会对增加的热量做出反应。

TED-Ed（视频版） That happens because spices trigger the same neural response in the brain that activates temperature receptors, which usually respond to increased heat. 发生这种情况是因为香料在大脑中触发了与激活温度感受器相同的神经反应，而温度感受器通常会对增加的热量做出反应。 TED-Ed（视频版） When the fever's over or you've won your race, your temperature receptors sense the decrease in heat and the hypothalamus brings your sweating response to an end. 当发烧结束或您赢得比赛时，您的温度感受器会感觉到热量减少，下丘脑会结束您的出汗反应。

Thermoreceptor（重定向自Temperature receptor）
A thermoreceptor is a non-specialised sensory receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In the mammalian peripheral nervous system, warmth receptors are thought to be unmyelinated C-fibres (low conduction velocity), while those responding to cold have both C-fibers and thinly myelinated A delta fibers (faster conduction velocity). The adequate stimulus for a warm receptor is warming, which results in an increase in their action potential discharge rate. Cooling results in a decrease in warm receptor discharge rate. For cold receptors their firing rate increases during cooling and decreases during warming. Some cold receptors also respond with a brief action potential discharge to high temperatures, i.e. typically above 45°C, and this is known as a paradoxical response to heat. The mechanism responsible for this behavior has not been determined. |
