I wonder if it is accurate to say that someone has a fever in his ear? Experienced people will say.

Folk saying: it is hot to miss you, and it is hot to scold you.

There are three kinds of ear fever. One is that you often feel hot in your ears after strenuous exercise. This is because when people exercise, their hearts beat faster and supply more blood to the muscles of their limbs. After physical exercise, muscles need less blood, but the heart can't slow down immediately, so more blood rushes to the heart. The skin of the head and ears is very thin and covered with rich blood vessels. When a large amount of blood flows through the ear, the blood vessels will expand and thicken, and the ear will turn red. Because blood has a certain temperature, ears will feel hot. After the heart gradually returned to normal, the blood vessels contracted and became thinner, and the blood volume in the ears decreased, so the fever stopped.

Secondly, when the outside temperature is low, the blood vessels contract when they are cold and look pale. At this time, if you walk into a room with high temperature, the blood vessels will suddenly thicken when heated, and your ears will feel hot.

Third, when you are shy, when you have a heated argument with others, or when you encounter difficulties in exams … you will feel your ears are very hot. This is because the cerebral cortex is highly excited and nervous, and the nerve instructions make the skin blood vessels dilate, the heart beats faster, and the blood flow increases faster.

Why does the ear suddenly get hot?

Suddenly have a fever, but always have a fever at the same time.

Best answer:

For example, a high fever can cause, I don't think you are like this, and then the nerve excitement caused by people's mental stress leads to burning ears. This is a physiological phenomenon, don't worry, if it is the first case, you should see a doctor as soon as possible.

There is a saying that when your ears are burning, then someone must be talking about you; However, two Australian scientists believe that brain waves can cause ear temperature changes.

Two scientists in Canberra, Australia jointly developed a high-tech helmet, which can monitor the abnormal situation of human brain activity by measuring the change of ear temperature; The invention undoubtedly provides the cheapest risk assessment method for patients who are about to undergo brain surgery.

Psychologist Nicolas Kjellbing is one of two scientists. He said, "If a certain part of the human brain is active frequently, then it needs more blood. The blood supply to the brain is mainly through the carotid arteries on both sides of the neck, which continuously delivers blood to the brain and the inner ear, so as long as the temperature of the ear is measured, we can clearly know which part of the brain is active frequently. " This invention is also a research project of Australian National University.

He also pointed out that the main purpose of this invention is to help patients who are about to undergo brain surgery to assess the risk of surgery. The prototype of the whole equipment costs $3,800. It can be used repeatedly to monitor brain activity, replacing the commonly used magnetic resonance imaging scanning technology.

The researchers also pointed out that after further improvement, this helmet can also be used to study the theory that the utilization rate of the left and right brains of the human body is different. Because the left brain of human body is mainly related to human language ability, while the right brain of human body controls vision and sense of space. Kjellbing said: "As far as the current research results show, some parts of everyone's left and right hemispheres are more active than others. But we can't directly judge which half of the brain is active. "

Of course, the invention can also point out the damaged brain function for accident patients, so as to help them recover.

Skye McDonald, chairman of the Australian Brain Injury Research Association, said: "This technology monitors the brain in a non-invasive way, so it will become a very useful research aid for measuring brain dysfunction in a wider range."
