What reason is children evening ear fever

summary

We sometimes have ear fever, which is actually a normal physical reaction. It doesn't matter. Let's find out what causes children's ear fever at night.

What reason is children evening ear fever

First, after strenuous exercise, people often feel that their ears are hot. This is because when people are exercising, their heart beats faster and more blood is supplied to the muscles of their limbs. After physical exercise, the blood required by the muscles is reduced, but the beating of the heart can't be slowed down immediately, so more blood flows 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 ear, the blood vessels will expand and thicken, and the ear will be red. Because the blood has a certain temperature, the ear will feel hot. After the heart gradually returns to normal, the blood vessels will contract and shrink, and the blood on the ear will be reduced, so there will be no fever

The second reason is that 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 high temperature, the blood vessels suddenly thicken when it is hot, and your ears will also feel hot

The third reason is that 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 feel your ears are very hot. This is due to the high excitement and tension of the cerebral cortex, which leads to the expansion of skin vessels and the acceleration of heart beat, It's also a physiological reaction that people often have. It's also a kind of unique performance of people, but it will be OK after a while.
