Emotions and Illness

The research on emotion in modern medical psychology has revealed the negative mechanism of emotion in psychosomatic diseases. Many diseases are related to human emotions. Negative emotional experiences such as tension, anxiety, depression, trouble, sadness, and disappointment in daily life can lead to negative emotions. Accumulation is the main cause of some diseases.

1. Emotions and cardiovascular and cerebrovascular diseases.



Some bad emotions such as anxiety, fear, anger and other emotions can lead to increased blood pressure, while severe and long-term anxiety and tension will cause central nervous system dysfunction, endocrine dysfunction, increase blood volume, and further increase blood pressure. More seriously, rage causes a surge in red blood cell counts, faster blood clotting, faster heart rate, and a sharp rise in blood pressure, which can have serious consequences. High blood pressure can cause cerebral blood vessels to rupture; blood coagulation too fast can lead to cerebral thrombosis; coronary artery constriction can lead to coronary heart disease, coronary artery occlusion, and even sudden death.

2. Emotional and digestive diseases.



Experimental studies on humans and animals have shown that when people are depressed or sad, gastric motility disappears, gastric mucosa becomes pale due to vasoconstriction, gastric juice secretion decreases, acidity decreases, and the food eaten cannot be digested, causing indigestion. When people are nervous, angry or anxious, gastric peristalsis intensifies, the gastric mucosa becomes red and congested, the secretion of gastric juice increases, and the content of gastric acid is high, which often leads to gastric ulcers. According to a survey by the American Academy of Medicine, among more than 500 patients with stomach problems, 74% of them are caused by bad mood.

3. Emotions and the immune system.



Intense and persistent emotional tension and depression can lead to the imbalance of excitation and inhibition of the cerebral cortex, thereby causing disorder of the body's endocrine function, inhibiting immune function, increasing the secretion of adrenal cortex hormones, resulting in a decrease in the number of antibodies, degeneration of thymic lymphoid tissue, and blood loss. The number of lymphocytes decreases and the cellular immune function declines, thereby impairing the anti-infective ability of the immune system and increasing the chance of the body to contract diseases.
