When the human body start to produces excessive mucus than normal range or when the mucus becomes thicker in consistency and becomes visible. This extra mucus moves out of the nose and gives+ rise to a condition named as a runny nose. When the excessive mucus runs down to the back of the nose and moves towards the throat then it will be referred as postnasal drip. Sometimes when a person wake up in the morning having a sore throat or a cough and this situation end up while clearing the throat (to clear the mucus that is settled at the back of the throat). If a person faces these type of issue then he or she may become the victim of post nasal drip. Now the question is what is mucus? Mucus is a secretion that helps to humidify the air which travels through the body and makes to feel comfortable. Mucus is basically a thick wet substance that keeps these areas moist and helps to trap and destroy the bacteria, viruses or other foreign invaders before these microorganism cause any infection in the body. In normal conditions, the mucus that presents in the nose is not visible usually because it combines with the saliva and run back of the throat and then ingested gradually. But the excess of it is not good for health.
