Bad emotions mainly include: persistent fear, depression, anger, anxiety, sadness, melancholy, jealousy, indifference, lack of emotional response to environmental changes, depression, emotional instability, emotional inversion (also known as emotional separation); Emotional conflict, nervousness and so on.
Medicine has proved that bad mood is harmful to health. The stimulation of bad emotions to the cerebral cortex will cause changes in systemic nerves and endocrine, and eventually lead to changes in organ functions, such as heart rate, blood pressure, gastrointestinal movement, etc., which will lead to the occurrence or aggravation of diseases. Scientists have done experiments: some mice are divided into two groups, one group is placed in a quiet and comfortable environment, and the other group is placed on a shaking table to keep the mice in a state of tension. Therefore, all other conditions being equal, the inspection shall be carried out after a period of time. Only 7% mice in the first group have cancer, while 80% mice in the second group have cancer. According to a survey, the morbidity and mortality of people who have been hit by the loss of their husbands are seven times higher than those of others within six months.
Someone followed up 35 patients with metastatic breast cancer and found that the average survival time of happy people was 22.8 months. The average survival time of people in a bad mood is only 8.6 months, and the survival time of the former is 2.3 times that of the latter. According to research and analysis, the main reasons are: long-term distress, depression and emotional depression will lead to decreased immunity, endocrine disorders and excessive prolactin secretion, which will worsen the condition. Being in a bad mood can also hinder the production of macrophages, lymphocytes and immune antibodies, resulting in immune deficiency, which in turn leads to the occurrence and aggravation of various diseases and cancers. Bad mood is more harmful to elderly patients with cardiovascular diseases. Someone studied 277 patients with myocardial infarction and found that 65% of them had bad mood before the onset.
The researchers also observed that the incidence of heart disease in middle-aged and elderly people with large fluctuations in bad mood is more than six times higher than that in middle-aged and elderly people who are calm when things happen. The reason is that bad emotions can make sympathetic nerves excited, and release a large number of bioactive substances such as norepinephrine and epinephrine in the body, which can accelerate metabolism, increase the amount of hypoxia in the heart, increase the burden on the heart, lead to coronary artery spasm, myocardial ischemia and hypoxia, and then lead to cardiovascular diseases such as arrhythmia, angina pectoris and myocardial infarction.
The influence of bad emotions on the body, from appetite to sleep, from breathing to blood pressure, involves almost all systems of the whole body. Modern medicine believes that diseases directly related to emotions include hypertension, coronary heart disease, bronchial asthma, ulcers, allergic enteritis, diabetes, autonomic nervous dysfunction, malignant tumors and so on.
