What is the fever in both ears?

Question 1: Who knows what ear fever is? 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, in winter, when we go back to the warm room from the cold outdoor, our ears will become red and hot. This is because the ear blood vessels contracted outdoors at low temperature expand indoors due to the rising temperature, and the blood flow accelerates, resulting in ear fever.

The third reason is that when you are shy, when you have a heated argument with others, or when you encounter difficulties in the exam ... you will also feel very hot in your ears. 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.

Fourth, why does the ear get hot when the phone calls for a long time? This is caused by radiation. The principle of mobile phone radiation is the same as that of microwave oven. Microwave radiation can cause molecular vibration inside food, thus generating heat. There is a magnetron in the microwave oven. This electron tube, called magnetron, is a microwave generator, which can generate microwaves with a vibration frequency of 2.45 billion times per second. Intense exercise produces a lot of heat energy, and food can be "cooked" immediately. It takes a long time to make a phone call, so my ears will get hot. However, the radiation of mobile phone is much smaller than that of microwave oven, but talking on the phone for a long time will damage your brain under the radiation for a long time, so don't always talk on the phone. In addition, some people may notice that when people are doing high-intensity mental work such as taking exams or solving difficult problems, their ears will also get hot. This is also related to blood circulation. An active brain relies on the carotid artery connecting the brain and trunk to transport stable oxygen and nutrients. Some blood will "wander" around the inner ear before it flows into the brain, so that the temperature of the ear will rise immediately. According to this, some scientists believe that by measuring the temperature of the ear, we can also understand the activity of the brain.

Question 2: What's with the ear fever? Ears are hot and hot. There is normal physiological capillary congestion, so don't be nervous. There is also a pathological state, going to the hospital. The explanations for this problem are as follows: First, after strenuous exercise, I often feel my ears are hot. 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. The third reason is that when you are shy, when you have a heated argument with others, or when you encounter difficulties in the exam ... you will also feel very hot in your ears. 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. If you have pain, you must go to the hospital for examination. The above is the explanation of this problem.

Question 3: What is the cause of binaural fever? It freezes at 30 o'clock, because it is winter. Because of the cold weather, the blood circulation in the ears slows down and the ears begin to feel cold. After entering the house, the blood circulation in the ear began to accelerate, causing the ear to get hot.

Just keep warm, I hope I can help you!
