What is Laryngitis?

Laryngitis(喉嚨發炎, 喉炎) is a condition caused by inflammation of the larynx or voice box. Within the voicebox are two bands of muscle, the vocal cords, which are stretched across the windpipe and allow us to speak and make sound when they vibrate together.  

The inflammation that causes laryngitis can be caused by many things. Usually, it is a short-term problem caused by a viral infection, but it can also be a short or long-term problem due to overuse or irritation of the vocal cords; for example from speaking or shouting a lot or from exposure to irritants like cigarette smoke or stomach acid reflux.  

Symptoms of Laryngitis   

• Hoarseness: When the vocal cords are inflamed or swollen, they can’t move as effectively to create sound, leading to hoarseness, the main symptom of laryngitis. Your voice may sound raspy, strained, or weak, making it difficult to speak normally 
• Loss of Voice: In some cases, laryngitis can temporarily cause you to lose your voice altogether, making it challenging to speak audibly or at all 
• Sore Throat: The inflammation in the larynx can cause throat discomfort, pain, or a scratchy sensation 
• Dry Cough: Laryngitis may accompany a dry, persistent cough, which can further irritate the vocal cords 
• Throat Irritation: You may experience a feeling of something stuck in your throat or the need to clear your throat frequently

What to do if you have laryngitis  

• Hydration: Stay well-hydrated by drinking plenty of fluids to maintain the lubrication of the vocal cords and prevent dryness  
• Vocal Rest: If you experience hoarseness or any signs of vocal strain, give your voice a break by refraining from excessive talking or whispering. Patients are often surprised to learn that whispering is actually more stressful on your voicebox than talking!    

How to reduce irritation of your vocal cords 

• Proper Vocal Technique: Learn and practice proper vocal techniques to help project your voice to minimize strain on the vocal cords, mainly if you regularly do a lot of public speaking, presentations - or singing! 
• Avoid Irritants: Limit exposure to irritants that can inflame the larynx, such as smoke, allergens, and pollutants. If you're a smoker, consider accessing support for quitting to protect your vocal health 
• Humidify the Air: Use a humidifier or vaporiser to add moisture to your home or workspace air. It helps prevent dryness in the throat and keeps the vocal cords hydrated. Air conditioning can make the air very dry!  
• Avoid Vocal Abuse: Refrain from excessive throat clearing, coughing, or using your voice when strained or fatigued. These actions can irritate the vocal cords and exacerbate laryngitis symptoms  
• Maintain a Healthy Lifestyle: Maintain a balanced diet, exercise regularly, and manage stress levels 
• Seek Treatment for Acid Reflux: If you have gastroesophageal reflux disease (GERD) or experience recurring acid reflux, seek treatment.
