WYSIWYG's comment has some good general idea: Many processes are affected by temperature including metabolism and growth rates. Reaction rates increase with temperature but not in case of catalysed reactions where the catalyst can operate at only an optimum temperature. Some related topics temperature effect on the rate of protein degradation ...

Short answer Humans sense temperature differences. Background (Including edits based upon comments) Because the question is "Do humans perceive temperature or heat-flux?", I will answer the answer from a psychophysical perspective, i.e., by dealing with sensory awareness. Just as with many other sensory systems, temperature sensors in the human body ...

Flux is defined as amount of heat transferred per unit area per unit time. Our body does not perceive heat flux. It perceives temperature and tries to adjust heat exchange mechanisms until thermal homeostasis is achieved (in all warm blooded animals). This is a feedback controlled process. If it were to measure heat flux then the body cannot sense if it ...

This is the modified answer in response to the discussion: Facts: There are warmth and cold receptors in the body at two places: The Peripheral receptors and the Central Receptors The peripheral receptors are present in skin and the central receptors in the body core at multiple sites the notable site being the hypothalamus The Temperature receptors have ...

An ectotherm is an [cold-blooded] organism which is dependent on external sources of body heat. They do not need to regularly consume food to warm their bodies. As a result, they can subsist on lower metabolic rates and varying internal temperatures (poikilothermy). However, physical activity is restricted to certain hours (night) and or habitats; ectotherms ...

Endotherms also called warm blooded animals have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside. In a hot region the body metabolism is tuned down (this is not as efficient as the adaptation to cold ...
