Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.
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 [ citation needed ] .
It is induced by mental stress and a cold atmosphere. In all cases, the primary cause is an underlying hyperactivation of the sympathetic nervous system. Although, with different types, the exact pathophysiology differs. In the primary type, there is an increase in sensitivity due to the reasons mentioned above resulting in vasoconstriction.
