The relationship between psychological factors and health and disease

Psychological activity is the interaction between individuals and the environment, and it is the subjective initiative of the human brain to reflect the objective reality. Influenced by subjective factors such as individual experience, knowledge and personality, different individuals will have different views and experiences on the same thing. The same person, in different time, different environment and different psychological background, will have different attitudes towards the same thing. These attitudes and experiences will affect one's physical and mental state, thus affecting one's health.

Mental health and physical health can influence each other. Good psychology is not only conducive to physical health, but also conducive to the rehabilitation of diseases. Bad psychological stimulation not only affects health, but even causes some diseases of the body. People who are in good health are often in a good mood, showing high spirits, optimism and enterprising spirit; Physical diseases often have an important impact on psychological activities.

In daily life, we often encounter all kinds of bad psychological stimuli, such as bereavement, professional competitions, terrorist incidents and so on. The body will produce a series of neuroendocrine reactions, which will lead to corresponding functional and metabolic changes in the central nervous system, immune system, cardiovascular system, digestive system, genitourinary system and so on. , so as to maintain the stability of the internal environment. If the stimulation is mild or lightened, the body can be restored to health, but if the stimulation is too strong, it will lead to dysfunction of systems and organs, causing various diseases and even death. Some well-known diseases, such as essential hypertension, coronary heart disease, diabetes and peptic ulcer, are closely related to long-term adverse psychological stimulation.

Psychological factors can lead to diseases.

Animal experiments provide convincing evidence: put two lambs born in the same litter in different places, give them the same food, water and sunshine, and then tie a wolf next to one lamb. Because of long-term fear, the lamb tied to the wolf soon died. The other grew up healthily.

Physical illness also has a significant impact on psychological activities. Symptoms of diseases, adverse reactions of drug treatment, surgical strikes, physical pain and social function decline caused by diseases, malignant tumors and serious chronic diseases will all affect patients' psychological activities, resulting in adverse emotional reactions such as anxiety, depression, worry, fear, conflict, pessimism and despair. These negative emotions will adversely affect the treatment and recovery of diseases and form a vicious circle.
