How is fever of right ear to return a responsibility everyday?

1. After strenuous exercise, often feel hot ears. This is because when people exercise, their heart beats faster, giving more blood to the muscles of their 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 will flow to the heart in the bathroom. 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. The blood has a certain temperature, so the ear 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.

2. In winter, when we return from the cold outside to the warm inside, our ears will become red and hot. This is because the ear blood vessels contracted in the outdoor low temperature expand in the indoor because of the rising temperature, and the blood flow speeds up, which leads to ear fever.

3. When you are 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.
