Thermoregulation is a form of homeostasis, a phenomenon which acts to maintain constant internal environment. The provision of a stable core body temperature is essential as many of the bodily processes carried out day-to-day are controlled by enzymes. These enzymes are temperature sensitive and act at a optimal rate at specific temperatures. Therefore, thermoregulation allows for metabolic processes to occur in the best possible conditions at the most suitable rate, while preventing loss of function, or denaturation, of the essential enzymes involved.
