How does the body cool down biology

WebHumans regulate heat generation and preservation to maintain internal body temperature or core temperature. Normal core temperature at rest varies between 36.5 and 37.5 °Celsius (°C), which is 97.7 to 99.5 °Fahrenheit (°F). Core temperature is regulated by the hypothalamus (in the brain), which is often called the body’s thermostat. WebThis occurs when a mammal sweats. Convection currents of air remove heat from the surface of dry skin as the air passes over it.
