Many people for the first time on stage speech have such feelings: the face of hundreds of people, the heart is very nervous, obviously summer, but still feel the pores in contraction, sweat hair in the erection, limbs shaking slightly; usually speak fluently, but this time a stammer; speak less than a few minutes, you feel very thirsty mouth …… nervous, a A small psychological condition that causes so many physiological reactions in people! There are many similar: when shy, flushed face; when angry, very thick breath; if you encounter anxious or upset, you may not sleep like a pancake all night …… These phenomena often do not attract our attention, always thinking that it is a temporary phenomenon, once the emotions pass, nothing will happen. This is the foolishness of modern people: for anything, he must see it in person to believe; for any reason must be proved by the most mechanical logical reasoning to believe. Because he always thinks that the psychological aspect is illusory. If someone drinks dichlorvos or inhales gas, he knows that it is poisoning; but if he is frightened into a certain way, anxious into a certain way or angry into a certain way, he will say: “It is a psychological effect.” He doesn’t take it seriously. Are “psychological effects” all illusory? Bad emotions can stir up qi and blood. Bad emotions can also make people whistle faster, resulting in “hyperventilation”, the body in a large number of carbon dioxide whistle out, the lack of carbon dioxide in the blood, so the blood vessels produce a violent reaction. This will first appear under the skin tingling, numb fingertips, followed by the possibility of rapid heartbeat, body tremors, dizziness, headaches, and even fainting. American physician John Schindler, based on his decades of experience in the field of medicine, said that he had a lot of experience in the field. Schindler according to his decades of experience in the practice of medicine statistics, a set of common diseases, caused by bad emotions, cervical pain accounted for 75%, swelling of the throat accounted for 90%, headaches and dizziness accounted for 80%, fatigue accounted for 90%, stomach distension accounted for 99%. These symptoms occur because the body’s circulation system of qi and blood is disturbed by bad emotions. Bad emotions can also directly affect the endocrine system and produce toxins. The hormones produced by the pituitary gland under bad moods are not a good thing: some of them raise blood pressure, some make muscles stiff, some make nerve spasms, some also affect kidney function, and some have to affect the normal work of other endocrine glands, which in turn produce more toxins. It is much more harmful to the body than hitting a stick or stabbing a knife. We must not underestimate. When bad emotions move, some toxins are produced, they are buried to a part of our body, like a mine, can be detonated at any time; moreover, bad emotions will plant bad seeds every time they move, and the second time it is more likely to start worse emotions. When anger, anxiety, anger and other bad emotions become a habit, people will spend their days being hate, resentment, annoyance, anger, annoyance and other bad emotions entangled. We can’t spend our lives being beaten with sticks and knives every now and then, much less swallowing a little poison every now and then, right? But if we are always in such a bad mood, it is tantamount to being stabbed, beaten with a stick, and swallowing poison. What’s next? It’s all kinds of diseases!
