What are the Causes of Laryngitis?
Acute laryngitis can be caused by either infection or damage/trauma to the larynx. The latter is sometimes referred to as mechanical laryngitis which is due to prolonged speaking or singing and very loud shouting. Singing can cause your vocal cords to vibrate at a faster rate than they normally should. The excessive vibration can damage the surface of your vocal cords, causing them to become inflamed. Some lifestyle choices can cause more serious long-term chronic laryngitis. Smoking is one cause of chronic laryngitis. Persistent exposure to tobacco smoke can cause long-term inflammation of the larynx. Alcohol abuse also can cause extensive laryngitis because the active ingredient in alcohol (ethanol) contains many impurities that can irritate your larynx.
