How does child ear have a fever to return a responsibility?

One is to finish strenuous exercise, often feel ear fever. This is because when people exercise, the heart beats faster and supplies more blood to the muscles of the limbs. After physical exercise, the blood needed by muscles is reduced, but the beating of the heart can't slow down immediately, so more blood rushes to the heart. The skin of the head and ears is very thin, which is full of rich blood vessels. When a large amount of blood flows through the ears, the blood vessels expand and thicken, and the ears turn red. Because the blood has a certain temperature, the ears will feel hot. When the heart gradually returns to normal, the blood vessels contract and become thinner, and the blood on the ears decreases, so there is no fever.

Second, when the outside temperature is low, the blood vessels contract when they are cold, and their faces are pale. At this time, if you enter a room with higher temperature, the blood vessels suddenly thicken when they are heated, and your ears will also feel hot.

Third, when you are still shy, when you have a heated argument with others, or when you have a difficult problem in the exam... You will also feel very hot. This is because the cerebral cortex is highly excited and tense, which leads to the expansion of skin blood vessels, the acceleration of heart beat and the acceleration of blood flow.
