Psychologically, music can directly affect people's emotions and behaviors. We know that music has various beats and rhythms, and the human body also has various physiological rhythms, such as pulse and breathing. If well coordinated, music can adjust the physiological rhythm. Because the human body has an obvious instinct to follow the rhythm of music, the speed of music rhythm can also drive the rhythm of body movements, and the "chant" in folk songs can reflect this effect. As a therapeutic method, the function of music can act on psychology through artistic appeal, which can not only enhance the disease resistance of human body, but also eliminate mental retardation. Rhythmic music can stimulate people's emotions, such as military music and March music, which can make people excited, excited and excited; Melodious music can make people feel quiet and relaxed. In addition, music can also affect people's mood through tone. This phenomenon was noticed as early as ancient Greece. They think that E is stable, D is warm, C is slow, B is sad and A is high.
We know that people's emotional activities are closely related not only to the cerebral cortex, but also to the endocrine system, autonomic nervous system, hypothalamus and limbic system. The limbic system of the brain is the highest center that regulates and dominates the activities of human internal organs. In this way, relaxing, pleasant, comfortable and pleasant music can improve and strengthen the functions of cerebral cortex, cerebral limbic system and autonomic nervous system, so as to better control and enhance the normal activities of various internal organs of human body. However, music therapy is not simply to get curative effect from appreciation, but as an activity to achieve therapeutic effect. Because music itself is a kind of structure, it is a practical and regular organization composed of various notes. Patients who want to participate in music therapy activities should learn and pay attention to the whole picture of music from beginning to end. In this way, patients must concentrate and make some efforts, that is, train their concentration and concentration ability through music activities, which many patients, especially those with mental illness and mental illness, just lack. At the same time, music activities can also cultivate patients to master or restore some new skills, such as mastering the melody, tone, rhythm and harmony of various music through singing, and the ability to coordinate with others. Through the performance of musical instruments, master the performance, playing methods and mutual cooperation ability of various musical instruments; This can encourage patients to increase the fun of life and understand the meaning of life, thus enhancing the initiative and self-confidence of life, which is conducive to physical and mental health.
In terms of physiological function, music can affect the physiological function of human body through sound. Sound is the vibration of sound waves and a kind of physical energy. Music, on the other hand, is a sound wave vibration with a certain frequency, which acts on various vibration systems in human body to produce beneficial vibration and coordinate the rhythm of various organs. This harmony is an important factor beneficial to physical and mental health. On the other hand, beautiful musical sound waves act on the brain to improve the excitability of nerves, and through the regulation of neurohumors, promote the human body to secrete some substances beneficial to health, such as hormones, enzymes, acetylcholine, etc., and play a role in regulating blood flow, promoting blood circulation, gastrointestinal peristalsis and saliva secretion, and strengthening metabolism, thus making people energetic and full of youthful vitality. In foreign countries, using music instead of narcotic drugs for caesarean section and tooth extraction is by no means simply relying on diverting patients' attention or implying the effect. Like acupuncture, it has a physiological and biochemical basis. The mechanism of acupuncture analgesia is not completely clear, but it has been found to be related to the increase of endorphins in human body. Therefore, different rhythm, melody, speed and coordination of music can show different effects such as sedation, excitement, analgesia, blood pressure reduction and mood regulation.
Because music can affect people's physiological activities, psychological activities, especially emotional activities, people can use music to improve and adjust the physiological and psychological functions of the human body, so as to achieve the purpose of treating diseases, strengthening the body and promoting health.
