ABSTRACT
In modern society, people are prone to several kinds of stress and stress-induced diseases. Stress is classified into physical chemical stress, physicochemical stress, and psychological stress. Physicochemical stresses are caused by cold, heat, injury, buzz, exhaust fumes, and so on. Physiological stresses are the result of starvation, infection, overwork, and so on. Psychological stresses arise from anxiety, strain, dissatisfaction, disappointment, anger, and other emotions. Stressful events induce both psychological and physical hypertension, which can lead to diseases such as duodenal ulcer, depression, sleeplessness, and autonomic imbalance. The significance of the correlation between health and stress is increasing, and therefore, relaxation techniques for stress reduction are important. Relaxation methods can calm down the overly tensed organism and prevent
stress-induced diseases. Thus, the use of psychosomatic medicines to induce relaxation has become necessary.
