Where does are body temperature come from?

Body temperature is primarily regulated by the hypothalamus, a part of the brain that acts as the body's thermostat. It maintains a balance between heat production and heat loss through various mechanisms, including metabolism, muscle activity, and blood flow. External factors like ambient temperature and physical activity also influence body temperature. The normal range for human body temperature is typically around 36.1°C to 37.2°C (97°F to 99°F).
