The key to prevent hoarseness is to let the vocal cords rest, talk as little as possible and drink more water, so that the inflammation of the vocal cords can be alleviated. If the vocal cords can get enough rest, the early vocal nodules have a chance to disappear, but if they drag on for a long time, they may need to be surgically removed.
It is suggested to keep your voice as low as possible when you speak. Talking loudly or shouting is easy to hurt your vocal cords and should be avoided. Speak slowly. Speaking too fast or too fast will cause muscle tension in the neck and throat and aggravate vocal cord injury; Don't cough or clear your throat. Coughing hard and clearing your throat are very harmful to the vocal cords, so try to avoid them.
If you feel the voice changes, you should let the vocal cords rest for more than two to three days to avoid irreversible lesions of the vocal cords. What should be reminded here is that when the vocal cords are damaged, low-pitched pronunciation will not make the vocal cords rest, but will aggravate the condition. When you have to speak, you'd better speak at a normal volume and speed.
