Breathing and body temperature. Computer artwork showing how breathing through the nose helps to regulate body temperature. When inhaling (left), heat from small blood vessels in the nasal cavity is transferred to the cooler air (blue arrows), warming the air up and cooling the nose down. When exhaling (right), heat in warm air (red arrows) from the lungs is transferred to the blood vessels, warming the nose and cooling the air.
