Body temperature regulation is the process by which the body maintains its internal temperature within a narrow range, typically around 98.6°F (37°C). This is crucial for optimal functioning of enzymes and metabolic processes. The body uses mechanisms such as sweating, shivering, and altering blood flow to the skin to achieve this balance. The hypothalamus, a part of the brain, plays a key role in temperature regulation by acting as the body's thermostat. It receives signals from temperature receptors in the skin and internal organs, prompting responses to either cool down or warm up the body as needed.
