As laryngitis is often caused by a common viral infection, such as a cold or flu, it's not always possible to prevent it. However, you can reduce your risk of developing the condition by: making sure you have the annual flu vaccine (if recommended by your GP) practising good personal hygiene – such as washing your hands before and after eating and after using the toilet avoiding close contact with people who have respiratory infections, such as a cold or flu – particularly if you're prone to laryngitis avoiding irritants, such as smoke or dust – particularly if you have a cold or other respiratory tract infection not smoking not drinking more than the recommended limits of alcohol consumption not regularly clearing your throat – as this can irritate the larynx (try swallowing instead) raising your head with pillows when you're sleeping – to protect your larynx from any acid reflux from your stomach during sleep not shouting or singing loudly or for long periods of time – it's important for people who regularly use their voice excessively to receive proper training so they don't damage their larynx
