Diet also plays a key role. Certain foods can encourage mucus production, especially ultra-processed foods and excessive sugar. On the other hand, a diet rich in fruits and vegetables provides vitamins and antioxidants that support the immune system. Foods high in vitamin C help reduce inflammation and fight mild infections that may be behind excess phlegm. In some cases, spicy foods can have a temporary decongestant effect, making it easier to clear the throat.
Gargling: A Simple and Accessible Solution
A classic and accessible method is gargling with warm salt water. This combination helps cleanse the throat, reduce irritation, and wash away some of the mucus. When done several times a day, it can significantly ease the sensation of persistent phlegm, especially when frequent throat clearing has caused irritation.
