The head has a number of organs that are very important to the human body, and maintaining the proper functioning of these organs requires a large supply of blood, which brings sufficient heat to the face In addition, from an anatomical point of view, the head is closer to the heart, which makes it easier to get an adequate supply of blood, and therefore is more ‘unafraid of the cold’ compared to the extremities of the limbs. It has also been claimed that the face has a better ability to protect itself from the cold (adapt to the outside environment) due to prolonged exposure. Compared to the head, the blood supply to the rest of the body lags behind, so it is understandable that it is easier to catch a cold.
