On the eve of Teacher’s Day 2013, the physical examination center randomly examined a total of 1,841 teachers in three schools in Changsha, and the results showed that 75.6 percent of the teachers suffered from chronic pharyngitis, ranking first among teachers’ occupational diseases. Wen Li (a pseudonym) is a third grade teacher and classroom teacher in an elementary school in Changsha, recently had to go to the hospital because of throat disease. As an elementary school teacher, facing the more active elementary school students, in addition to the normal teaching curriculum, Wen Li also had to often need to maintain order in the class with a loud voice. “At first just feel throat discomfort, and then repeated several episodes, and now often feel a foreign body in the throat, there is phlegm can not cough, the most serious time, even speech can not speak.” The final hospital examination results show that Wen Li suffers from chronic laryngitis with vocal cord nodule formation, must recuperate from treatment. Talking a lot is the most important feature of the teaching profession. Long-term, excessive and inappropriate use of sound, resulting in a much higher incidence of chronic pharyngitis in teachers than in other professions. In the hospital’s physical examination of a total of 1,841 teachers in three schools in Changsha, chronic pharyngitis among teachers was 75.6%, the most common and most serious occupational disease in the teaching profession. Chronic pharyngitis is not only uncomfortable throat, patients will often feel dry throat, burning, itchy throat, foreign body feeling or phlegm obstruction, speak with a hoarse voice, easy fatigue, and some even hoarseness or loss of voice, largely affecting work and life. What can be done to solve the problem? Suggestion: correct incorrect vocalization. It is understood that most primary and secondary schools have not yet promoted microphone teaching, teachers still use the “loud shouting” way to teach classes, only in the multimedia classrooms in colleges and universities, there are microphones can be used. Teachers should pay attention to change the way of vocalization, change the chest vocalization to abdominal vocalization. In layman’s terms, the throat muscles should be relaxed when vocalizing, not to have the feeling of tight lock, with abdominal deep breathing, so that the airflow smoothly and economically through the throat vocal door, effectively impact the vocal cords and achieve the purpose of vocalization. The sound that comes out this way is bright and long-lasting. In addition, teachers should also pay attention to control the volume and speed of speech in the lecture, try to speak calmly, can not be anxious and irritable, the larynx in a relaxed state, looking for a fixed pronunciation of the fulcrum to maintain the same tone of speech; consciously let the vocal cords rest and relax during breaks between classes; commonly used warm boiled water, mint and other tablets to moisten the throat to stimulate saliva secretion, moisten the throat; do not eat or minimize the consumption of spicy and irritating The food is not spicy, cold and so on. ”At the same time, should also pay attention to rest, regular rest and rest, reduce the number of colds, such as acute inflammation of the throat, should rest sound, and timely standardized treatment, can not be forced to adhere to the class, if the continued use of sound, this will cause some irreversible damage to the vocal cords, seriously affect the quality of vocalization.”
