Phlegm is caused by bacterial or viral infections,
or by breathing in contaminants or dust in air
Phlegm can get stuck in your throat, making it difficult to breathe,
while coughing to clear the phlegm can also irritate your throat.

Prevention before phlegm symptoms get worse is important.


Viruses and bacteria taken in from the air may adhere to the mucosa of the throat. Make it a habit to gargle to prevent viruses and bacteria from entering your body.


Hands that come in contact with anything can carry viruses and bacteria. Wash your hands frequently with soap and hot water. Always keep your hands clean.

Regular hydration

The throat has the function of eliminating foreign substances such as viruses and bacteria. When your throat becomes dry, this function deteriorates. Hydrate yourself frequently and keep your throat moist.
