Is there anyone who is wondering why the ears sometimes get hot

There are three cases of ear fever. One is that after strenuous exercise, you often feel your ears heat up. This is because when people exercise, their hearts beat faster, pumping more blood to the muscles of their limbs.

After the body exercises, the muscles need less blood, but the beating of the heart cannot be slowed down immediately, so more blood rushes to the heart. When a large amount of blood flows through the ears, the blood vessels will dilate and thicken, and the ears will be red, and the ears will feel hot because the blood has a certain temperature. When the heart gradually returns to normal, the blood vessels shrink and narrow, and the blood in the ears decreases, so that the fever stops.

The second is that when the outside temperature is low, the blood vessels shrink after being cold, and the face is pale, at this time, if you walk into the room with a higher temperature, the blood vessels suddenly become thicker when heated, and the ears will also feel hot.

The third is when you are shy, when you have a heated argument with someone, or when you have a difficult time in ......an examYou will also feel hot at the base of your ears. This is because the cerebral cortex is highly excited and nervous, and the command nerves cause ** blood vessels to dilate, the heart beats faster, and blood flow increases.

Ears suddenly burn, is someone really missing you? See what the experts have to say!

Is it your background or that girl's background? Temperament, beauty, family background, etc. You try to say you don't like him and see how he reacts. When my girlfriend tried it, my tears fell. Think for yourself. Empathy, you have to learn to use it well.

Depend on. There are still people who believe this. My ears have never been hot.

Yes, there will be good weather tomorrow.

It seems to be true, but I don't believe it.

Sometimes, our ears will heat up inexplicably, many people don't know what causes it, generally from a superstitious point of view, there are many sayings, such as the left ear fever may mean that there are relatives missing you, if the right ear is hot, it may mean that there is a lover who misses you, if both ears are hot at the same time, it may mean that you are left and right.

Some people also distinguish the meaning of ear fever according to the time, and ear fever at different times represents different meanings. However, from a scientific point of view, there are generally several cases of ear fever, one is because the human body has just finished strenuous exercise, the human body's heartbeat is accelerated, blood circulation is accelerated, and the speed cannot be slowed down immediately, so that the weak parts of the human head, ears and other weak parts are congested, resulting in the expansion of blood vessels in the ear area, thus causing the phenomenon of ear fever.

The second reason may be because of the principle of thermal expansion and contraction, when people are in a low temperature environment, the blood flow in the ears is slow, if suddenly into a warm environment, the blood will suddenly accelerate, the blood vessels will suddenly thicken, and the ears will be hot.

Thirdly, when people are too excited and nervous, their ears will also be hot, such as when they are shy, when they are arguing with others, when they are nervous about exams, etc., these emotions will make people's blood vessels dilate, heartbeat faster, blood circulation faster, so that the ears will heat up.

In addition, if the ear is inflamed, there may be a fever. For example, often picking out the ear, resulting in the ear being gouged out, or the ear is watered when bathing or swimming, and the infection is inflamed, or because the ear is pierced, the wound is not properly disinfected, causing inflammation and pus in the wound, which will cause the ear to heat up.

Because the head, face, and ears are very thin, and they are covered with abundant blood vessels, when a large amount of blood flows through the ears, the blood vessels will dilate and thicken, and the ears will be red, and the ears will be hot because the blood has a certain temperature. Then when the outside temperature is low, the blood vessels shrink after being cold, and the face is pale, at this time, if you walk into the room with a higher temperature, the blood vessels suddenly become thicker when heated, and the ears will also feel hot and red.
