Music therapy has so far been considered useful for patients with a variety of diseases. In particular, in a modern society where there are a lot of stresses caused by external stimuli with malignant influences on both physiological and psycological functions in human, music is of great importance in the healthy care to reduce such stresses and anxiety. Also, it is a big problem that as unpleasant stresses strongly compromise bioactivities by adversely affecting the human nervous and endocrine systems as well as the immune system with a key role in prevention of infectious diseases and cancer. Here, I mentioned the effectiveness of music therapy with a Mozart music in maintaining our health. Our experiments concerning the Mozart music therapy show that (1)faster decreases of heart rate and blood pressure are seen, (2)the salivary IgA antibody and digestive enzyme levels are elevated, (3)the body temparature is raised, (4)an ability of salivary secretion is enhanced, (5)the salivary cortisol level is decreased, (6)the salivary insulin level is increased, and finally (7)the number of peripheral lymphocytes and also the interferon-γ production are augmented and so on. Additionally, other investigators have reported that listening to Mozart music enhances spatial-reasoning and IQ by 8-9 points, improves cognitive performance of patients of Alzheimer's disease, and ameliorate auditory disturbance. Thus, it is suggested that Mozart music therapy will be of great help to improve the various diseases caused by unbalance in autonomic nervous system, particularly by a stress-induced hyper-activation of sympathetic nervous system in everyday life-style. In conclusion, pleasant music such as Mozart music can be used as an intervention against diseases which are associated with our life-style.
