In recent years, numerous studies have confirmed the important role of psychological factors in asthma attacks, and it has been recognized that asthma is one of the typical psychosomatic diseases of the respiratory system. Many mental factors, such as anxiety, disappointment, distress, anger, fear, frustration, etc., can trigger asthma or create a persistent asthma state. The common mood disorders and psychiatric symptoms of asthma patients are mainly anxiety, depression and dysthymia, and their personality traits are mostly dependent, anxious, agitated, emotionally unstable, childish and introverted. Emotional disorders and personality defects make the body’s immune function decrease and sensitivity to the outside world increase, which can easily trigger and aggravate asthma; while asthma attacks can cause emotional tension and anxiety symptoms. This vicious circle makes asthma attacks recurring and difficult to cure. Whistle function and emotions are very close, in a variety of emotional states, there will be a special whistle rhythm and depth changes. For example, when people are crying, sighing, laughing, angry and other emotional states, will be accompanied by corresponding changes in whistling. Although whistle function tests are not specific for allergic diseases, they can be used to determine the nature and extent of damage to the whistle system. In allergic diseases, especially bronchial asthma, inspiratory function tests can be performed to determine the degree of physiological involvement of the airways and lungs, and to assess the effectiveness of treatment.
