Contrary to popular belief, lemon is not a hazard for an inflamed larynx. Lemon is known to help reverse voice loss. If you are suffering from a sudden loss of voice; all that you would need to do is to mix a few drops of lemon juice and honey in a glass of lukewarm water. Alternatively, one could even dissolve a few drops of lemon juice in a glass of warm water and add a pinch of salt.
Our voice therapists recommend that for every 90 minutes of voice use, you need 10 minutes of voice rest. Overuse can damage the vocal cords, and if you often find you have lost your voice by the end of the day or after an hour of singing, your vocal cords may be experiencing tissue damage. A laryngologist will examine your vocal cords for growths or other conditions and may recommend voice therapy to learn techniques that reduce the stress on your vocal cords, and hopefully help to reverse any tissue damage. These therapy techniques focus on the fundamentals of voice production and re-balancing the vocal subsystems.
