why does body produce mucus when sick
Mucus, colds and sinus problems. We may not even notice mucus is there until a cold comes on. If you've got a cold, you produce too much mucus, Mr Hern says. You can actually feel it in your nose and throat. It occupies volume there.. Extra mucus is part of the body's natural response to a cold. It's all part of an acute inflammatory response. You get more blood going to the nose and sinuses and more mucus to try and act as a protective mechanism to try to get rid of the viral infection. However, in itself, it causes some of the symptoms of a cold. The sinus drainage pathways are quite narrow and convoluted.
