Allergies
Many people often think of sneezing, itchy eyes, or a running nose when it comes to allergies. However, these conditions can also affect your vocal cords and trigger laryngitis in many ways. For example, an allergic reaction would lead to swelling vocal cords, while post-nasal drip can move the mucus from the nose to the throat and irritate these areas. Clearing and coughing the throat would even strain and worsen your voice. In addition, some antihistamine drugs for allergic issues would dry out your throat’s mucus, thus harming the vocal cords as they require moisture to operate. [10]
