What does a burn on the left ear mean

Many people have experienced a hot left ear in their daily lives. This is actually a natural phenomenon and a natural reaction of the body. For example, poor blood circulation or excessively cold weather or a large temperature difference in the space may cause a hot left ear. Some people believe from a superstitious point of view that a hot left ear means that someone who has a crush on you is thinking about you. So what does a hot left ear mean?

1. The surrounding environment is too hot, especially when moving from a cold place to a warm place in winter

2. Poor blood circulation

3. Frostbite

4. Some people think that when you feel your ears are hot, someone must be talking about you; but two Australian scientists believe that the changes in ear temperature are caused by brain waves. Two scientists in Canberra, Australia, have developed a high-tech helmet that can monitor abnormalities in brain activity by measuring changes in ear temperature; an invention that could provide a cheap way to assess risk for patients about to undergo brain surgery. Psychology expert Nicolas Cherbuin, one of the two scientists, said: "If a specific part of the human brain is active frequently, it needs more blood supply. The blood supply to the brain is mainly through the carotid arteries on both sides of the neck, which continuously transport blood to the brain and inner ear. Therefore, as long as we measure the temperature of the ear, we can clearly know which specific part of the brain is active frequently." The invention is also a research project of the Australian National University. He also pointed out that the main use of this invention is to help patients who are about to undergo brain surgery to assess the risks of the operation.

The entire prototype cost $3,800. It can be reused to replace the currently commonly used magnetic resonance imaging scanning technology to monitor brain activity. The researchers also pointed out that after further improvements, the helmet could also be used to study the theory that the left and right brains of the human body are used at different rates. Because the left brain of the human body is mainly related to human language ability, while the right brain of the human body controls the functions of vision and spatial sense. "The results of current research show that one part of the left and right brain is more active than the other part," Sherbin said. "But we can't directly determine which part is more active."

Of course, this invention can also point out damaged brain function in accident victims to help them recover. Skye McDonald, president of the Australian Brain Injury Research Association, said: "This technology monitors the brain in a non-invasive way, so it will be a very useful aid in research to measure abnormalities in brain function on a larger scale." There are many nerves in the ear, and if you touch them, they will heat up. Because the ears have a fever, there is another solution: go to the doctor
