Why on earth is this?
People's psychological phenomenon is the reaction of objective things in the brain. The brain is the advanced center of the human body, which plays a dominant or regulatory role in all functions and activities of the body. Modern medical research has proved that strong emotional fluctuation will disturb the normal function of the brain, make the internal function of the body dysfunctional and cause many diseases. Pavlov pointed out: "All stubborn and heavy worries and anxieties will definitely open the door to various diseases." It was found that 59% of the 170 cases that died in a short time after experiencing intense stimulation and intense emotional fluctuation died after the news of personal misfortune and huge loss came; 34% died in dangerous or threatening situations; 7% died of ecstasy. Pirogov, a Soviet scientist, observed that the wounds of winners heal faster and better than those of losers.
People's mental state in daily life has obvious influence on cardiovascular function. For example, when you are emotional, your heart will speed up, and when you are shy, your facial blood vessels will expand. These are common phenomena. Clinical observation shows that angina pectoris often occurs when people are emotional. This is because when they are emotional or nervous, the nervous system is in a state of high excitement, and the content of theanine in the blood increases, which causes vasoconstriction, high blood pressure and increased myocardial oxygen consumption, thus causing sudden angina pectoris and even acute myocardial infarction in severe cases.
Most people have a good appetite when they are happy, but they lose their appetite when they are sad. Studies have shown that when the mood changes, the vagus nerve is excited and the stomach function is affected. In addition, emotions have obvious changes in intestinal function. For example, the emotions of anger and anxiety are excessive colon activity, which leads to continuous contraction of colon, narrowing of colon, increased secretion of lysozyme, brittle intestinal conjunctiva, punctate bleeding and even erosive ulcer.
A psychologist did an experiment: two sheep were put in two cages and given the same living conditions. The only difference is that there is a cage near the wolf's den. Experiments show that under the same living conditions, sheep that fall into the wolf's den will eventually lead to ulcers due to fear and anxiety. After that, the sick sheep were moved to a far place where there were no wolves, and the ulcer gradually healed after corresponding treatment. If you put the sheep next to the wolf's den again, the ulcer will recur.
The above experiments show that the stimulation of mental factors plays an important role in the formation of ulcers. Expert research has found that when a person is subjected to intense and persistent nervous stimulation, a series of emotional changes will occur, such as anger, fear and anxiety. These emotional changes can directly affect the control of the cerebral cortex center to the subcortical center, disturb the physiological function of the stomach through the change of neural regulation mechanism, make the gastric mucosa hyperemia and edema, enhance gastric peristalsis, significantly increase gastric acid secretion, and even corrode the gastric mucosa.
Too much tension will lead to serious nervous system disorder and various neurosis, including neurasthenia, hysteria and obsessive-compulsive disorder, and even mental disorder and behavioral disorder in severe cases. This is how most so-called reactive psychosis is caused. It is a mental disorder caused by strong, sudden or lasting mental factors.
Endocrinologists tell people that mental burdens such as excessive tension and long-term anxiety are important factors that induce hyperthyroidism. From the complaints of hyperthyroidism patients, we can know that they go to school, go abroad, be promoted, be promoted, etc. It can lead to mood swings, but due to overwork and continuous mental stress, it is more closely related to the onset, and there are obviously fewer patients with hyperthyroidism in rural areas.
Although there are many causes of cancer, in recent years, a large number of scientific experiments have confirmed that bad psycho-social stimulation is a powerful factor to promote cancer, which has also been confirmed by animal experiments. If dogs are divided into two groups, one group will be in a state of panic for a long time, while the other group will live in a quiet environment. Results Three of the six dogs in the first group died of cancer, and all the four dogs in the second group were safe and sound. Modern psychosomatic medicine experiments have proved that bad psychological factors, excessive stress and stimulation, depression and sadness can degrade thymus through cholesterol-like effects, cause immune lymphocyte maturation obstacles, inhibit immune function and induce cancer.
We all know the story of "the shadow of a snake with a bow". When we saw the shadow in the cup, we mistakenly thought it was swallowing a snake. People who were in good health immediately became very ill and almost died. When the truth came out, they were left without medicine. Psychoanalytic psychologists once treated a girl with a strange skin disease. Her skin couldn't see the sun, so she had to wrap herself up when she went out. Once her skin is exposed to the sun, she will get sick, tingle all over and feel uncomfortable. Doctors are at a loss. However, after long-term psychological treatment by parents of psychoanalysis, it was found that the reason for this disease was that girls especially liked to wear short skirts when they were young, but their mothers did not allow her to wear them and insulted her shameless. Girls have a strong desire to wear skirts. The more they refuse to wear them, the more they want to wear them. Finally, the subconscious defense system comes into play, and the result of solving this contradiction in her heart is that she has such a skin disease, which makes her consciousness accept this reality rationally-not that I don't want to wear a skirt, nor that I dare not wear it, but that I have a skin disease and can't wear it. When this subconscious is revealed, the girl is no longer allergic to sunlight, and the skin disease that bothers her disappears. In the movie Heidi and Grandpa, Heidi met Clara, a rich girl, and became Clara's Bandu and her only friend. Clara lost her mother when she was young, and she couldn't stand after a serious illness. She can only be trapped in a mansion in a wheelchair. Later, Clara, who was in a wheelchair, followed Heidi to Heidi's grandfather's house and herded sheep in the Alps in the distance. One day, happy Heidi looked at a dancing butterfly, lost in thought, and suddenly the butterfly was about to fly away. Heidi was absent-minded, completely unconscious of chasing butterflies ... or Heidi found out, and suddenly Heidi exclaimed, "Clara, you stand up!" " Clara noticed that she was standing.
A smile that heals the soul
How much do we really know about our hearts? We can't say that we don't know anything, but at least the above shows that psychological factors play an important role in the occurrence, development and prevention of diseases. In order to prevent the occurrence of diseases, we must pay attention to mental health.
