Homeostasis is the process by which organisms maintain a stable internal environment, essential for survival. Thermoregulation, a crucial aspect of homeostasis, involves keeping body temperature within a narrow range to ensure the proper function of enzymes and proteins. The hypothalamus acts as a central regulator, initiating responses like sweating and shivering to adjust temperature. Physical fitness can enhance thermoregulatory efficiency, and neural mechanisms play a key role in quick temperature adjustments.
