The human vocal organ is a radiating organ composed of speech sound and song. It is like a piano, and with proper care and playing, it can produce a beautiful sound for a long time.
In addition to tobacco and alcohol stimulation, improper vocal methods and excessive use of voice, there are many diseases that can cause hoarseness, and some are even very serious. Common diseases include: acute and chronic laryngitis, vocal cord nodules, vocal cord polyps, laryngeal nodules, and laryngeal cancer. In addition, laryngeal tumors such as esophageal cancer and lung cancer can also cause hoarseness after compressing the laryngeal nerve.
Prevention of voice diseases and voice health care
First, there are two main preventive measures for voice system diseases: one is to pay attention to voice health care, and the other is to strengthen voice practice.
(a) Specific measures for voice health care
1, teachers can drink some warm water in moderation before class to ensure that your throat is lubricated.
2.When lecturing, you should stand upright with your body and eyes flat, and try to make your line of sight at a 90-degree angle to your spine.
3.Try to avoid shouting to reduce the damage to your voice.
4.When you feel your voice is fatigued, hoarse, or have a sore throat, you should try to take a break to reduce the use of your voice or to ban it for a short time.
5.Grow plants in the classroom and water them often to avoid dry air in the classroom.
6.If the outdoor air is cold, use a scarf around your neck and wear a mask when you go out to avoid direct stimulation of the throat by cold air.
7.Strain to quit smoking and drinking.
8.Strengthen physical exercise, enhance physical fitness, prevent colds, is also a powerful measure to prevent throat disease.
9, try to avoid taking drugs with drying effect, such as antihistamines.
(B) Voice health care methods and exercises.
1, throat massage: use the thumb and index finger to press the sides of the laryngeal nodes up and down. Acupressure force to feel comfortable, not too much force, about 2-3 minutes each time.
2, towel hot compress: the towel soaked in hot water and wrung out on the neck (temperature to not burn the skin is appropriate), repeated several times. The above health care method can improve blood circulation in the throat, eliminate fatigue, enhance secretion, reduce dry throat, sore throat, and throat discomfort after practicing singing.
(C) dietary health care: For those who use voice professionally, special attention should be paid to supplement vitamin A, vitamin C and B vitamins from the diet. If there is a lack of vitamin A, the nasopharynx and throat will easily become dry and inflamed; if there is a lack of vitamin C, it will easily lead to bleeding of the nasal mucosa and weakness of the vocal cords; B vitamins can maintain the normal function of the ear, nose and throat. Choose more foods that are good for protecting your voice: foods that are good for your voice include apples, pears, oranges, bananas, green radishes, tomatoes, cucumbers, chard, cabbage, rape, celery, spinach, honey, tofu, soy milk, eggs, etc. These light foods are good for moistening, clearing and opening the voice, and contain many vitamins and inorganic salts, which are good for maintaining health. Eat less cold and hot food: food that is too hot can easily cause congestion in the mucous membrane of the throat, affecting pronunciation and resonance. Excessively cold food can cause abnormal contraction and vasospasm of the muscles of the pharynx, which can impair venous blood return and lead to mucosal damage and affect the normal function of the laryngeal muscles and vocal cords. Do not drink too much alcohol and eat too spicy things, because alcohol and foods such as garlic, pepper and peppercorns stimulate the mucous membrane of the mouth, throat and esophagus the most and make these parts congested, swollen and make the voice out of tune. (D) health care habits: human vocal cords are very delicate, do not use your voice excessively when the upper respiratory tract infection, and do not use your voice excessively during the menstrual period or voice change period, during which the organs of articulation are congested, uncontrolled rapping and shouting will make the vocal cords “worse”. Resolve to quit smoking cigarettes. Because the lit tobacco mist contains a lot of nicotine, it is easy to reduce the defense ability of the respiratory tract and the mucous membrane of the articulatory organs. The lack of sleep will aggravate the congestion of the articulatory organs and make the blood in the body acidic, resulting in muscle fatigue, especially the small muscles of the larynx are very sensitive and often cause hoarseness of the vocal cords.
