Music has an excellent therapeutic effect on some diseases with poor therapeutic effect, such as diabetes, bronchitis, neurasthenia, low back pain, insomnia and so on.
Music can be divided into instrumental music and vocal music. Music therapy is mostly instrumental music. Melodious music enters the human body through hearing, and its rhythm and sound can stimulate the cranial nerve system, prompting the body to secrete some biochemical substances beneficial to physical and mental health, such as hormones, enzymes, acetylcholine and so on. It has the functions of pleasing body and mind, relieving fatigue, relieving stress, lowering blood pressure, helping digestion, improving circulation and increasing blood flow, and is helpful to improve people's immune function.
Babies often listen to music to promote their intellectual development. Pregnant women can have prenatal education when they listen to music, but they must carefully choose music tapes that have been appraised by experts and technical supervision departments to prevent fetal hearing damage.
According to medical clinical experiments at home and abroad, it is generally believed that music therapy is effective for physical and mental diseases such as hypertension, cardiovascular diseases, gastrointestinal dysfunction, pain, neurasthenia, listlessness, insomnia and dreaminess, psychological disorders, and bad emotions.
But not all music is good for people's health. Some psychologists have done investigation and analysis, and found that band members who mainly play classical music are mostly calm and happy. More than half of the band members who play modern music or mainly play modern music have a bad temper and are easily nervous. Some people often suffer from insomnia, headache, earache and diarrhea. The international standard for noise deafness is 90 decibels. According to the measurement, the volume of rock music is 90 ~ 1 10 dB, disco music is104 ~14 db, and symphony is generally about 80 dB. Otologists point out that playing loud, fast-paced and exciting concerts all day leads to sensorineural deafness.
Scholars also found that harsh concerts strongly stimulate the nervous system and even destroy the normal functions of the heart and vascular system, while people who often enjoy romantic music are cheerful, positive, responsive and psychologically healthy. So music therapy uses music that has been proved to be effective by clinical experiments. Generally, dance music, concerto, symphony and other genres are mostly classical instrumental music, or some light and smooth light music such as classic movie music, classical music sketches and folk instrumental music.
