Vocal an Voice Health
Dr. Richard Vivero, Otolaryngologist with Baptist Health South Florida, explains stress, exhaustion, diet, allergies, singing or talking a lot, and smoking can cause changes in the vocal cords.
He also points out the vocal cords are constantly used, because speaking is a repetitive motion, for example, and they can break them down and develop damage. "If you are constantly singing, because of the constant trauma of the vocal cords hitting each other as they vibrate, they thicken and that creates the nodule."
