The constant sensation of having phlegm in the throat is one of the most common discomforts and, at the same time, one of the most misunderstood.
Some describe this discomfort as a “knot ,” a frequent need to clear the throat, or a persistent pressure that doesn’t go away.
Although it is usually harmless, when it becomes recurrent it can affect quality of life, rest, and even daily concentration.
Phlegm is a natural substance produced by the body. Its main function is to protect the airways by trapping particles, dust , and microorganisms before they enter the lungs. The problem arises when it is produced in excess or becomes thicker than usual.
Why does phlegm accumulate in the throat?
There are several reasons why a person might start to feel more phlegm than usual. In many cases, it’s the body’s defense mechanism against everyday stimuli such as the following:
– Changes in temperature or weather, especially cold or very dry environments
– Seasonal allergies, which stimulate mucus production
– Colds or mild respiratory infections, even after recovery
– Exposure to dust, smoke, or pollution
– Occasional acid reflux, which can irritate the throat
– Dehydration, which thickens natural secretions
