Why do people blush when they are excited? What is produced in the body?

In fact, blushing is the command of the mind. It turns out that our visual and auditory nerves are concentrated in our minds. When we see and hear things that make us shy, our eyes and ears will immediately transmit the news to the cerebral cortex, which will stimulate the adrenal gland in addition to contacting the relevant parts. When the adrenal gland is stimulated, it will respond immediately and secrete adrenaline. Adrenaline has a characteristic. When it is secreted in a small amount, it can make the blood expand without reflux, especially the subcutaneous small blood vessels of the face. But when it is secreted in large quantities, it will cause vasoconstriction. When we feel embarrassed, it is the cerebral cortex that stimulates the adrenal gland and secretes a small amount of adrenaline, so our faces are hot and red. Not only will you blush when you are shy, but you will also blush when you are happy and angry. When you are extremely angry, your face is not only red, but also red and You Lan, and sometimes it turns pale. This is because the adrenal gland is secreted in large quantities, which makes blood vessels contract, alternately hyperemia and anemia, or makes blood vessels in a state of anemia for a long time. In fact, it is very simple to overcome blushing. Just when you see something that excites you, try to make your mood as calm as water, then make more new friends, participate in more social activities and communicate with strangers. Try to do it! The psychological adjustment that is easy to blush in front of people enters the society, and the problem of blushing in front of people is unbearable. In fact, I know there is nothing to be afraid of, and I want to change myself and communicate freely with others, but I just can't. Sometimes when I talk to people I don't know very well, I feel "Gordon" in my heart, my heart beats faster and my blood rushes straight to my face. I don't want to say my embarrassment, but I also call others inexplicable, and I am often laughed at by others, which makes me scared when I associate with people, and I dare not associate with people. However, they are eager to communicate with others. In their body, they often experience two different self-wars: one is shyness, cowardice and lack of self-confidence, and the other is forcing themselves to change themselves. So I feel that life is really too heavy and tired. This is a mental illness called acrophobia. Everyone will feel nervous or excited when interacting with unfamiliar or more important people, which will cause sympathetic nerve excitement and increase the secretion of catecholamine such as norepinephrine, thus making people's heart beat faster and capillaries dilate, that is, blush. This is a normal reaction in interpersonal communication, and it will become accustomed to it over time. However, due to your lack of self-confidence, you pay special attention to the evaluation of others and your performance in front of others, so that you are particularly concerned about blushing. I'm afraid people will say you because of this, and I don't want to blush, but I can't get rid of it. Seeing people blush becomes your heart disease. Before you associate with people, you are worried that you will blush. When dealing with people, you will seriously experience whether you have blushed. Over time, the corresponding areas of the brain will form a sense of excitement. As soon as you enter the environment of communication with people, you will feel hot on your face and anxious inside. Coupled with other people's comments or ridicule, you will be more nervous and afraid to meet people, thus forming acrophobia. Erythrophobia can be treated. First of all, you should take a natural attitude towards blushing, allow it to appear and exist, don't resist, don't suppress, don't hide, don't worry and worry about blushing, so as to eliminate the tension and worry caused by blushing and interrupt the vicious circle caused by it. Secondly, we should exercise our self-confidence. Most people who blush easily in front of others lack self-confidence and have an inferiority complex. Therefore, strengthening the cultivation of self-confidence and overcoming inferiority complex can play a fundamental role.
