Throat clearing is one of the most traumatic things you can do to your vocal folds. When you clear your throat, you create an extreme amount of movement of your vocal folds, causing them to slam and rub together. Sometimes people do not even know that they are clearing their throats; it has become a habit. Often they say that they feel something in their throat, like phlegm or mucus. The majority of the time; however, when you clear your throat, there is simply nothing there. One thing you have accomplished is to create more vocal fold trauma.
