The main method through which mammals regulate their body temperature is thermoregulation. Mammals maintain a stable internal temperature despite external temperature fluctuations, a characteristic known as homeostasis. They employ various mechanisms for thermoregulation, including sweating, shivering, and adjusting blood flow to the skin. These physiological responses help to dissipate heat or generate warmth as needed. Effective thermoregulation is crucial for optimal metabolic function and survival, enabling mammals to thrive in diverse environmental conditions.
