How does temperature in the body work?

Body temperature is regulated through a process called thermoregulation, primarily controlled by the hypothalamus in the brain. It maintains a stable internal temperature around 98.6°F (37°C) by balancing heat production from metabolism and muscle activity with heat loss through processes like sweating and blood flow adjustments. Various factors, including environmental temperature, physical activity, and hormonal changes, can influence body temperature. When the body becomes too hot or too cold, it initiates responses to restore balance, such as sweating to cool down or shivering to generate heat.
