4. Excess mucus
Excess mucus is a pretty gross, but very typical symptom of a URI. The trademark snotty nose is what most medicine companies and their associated brands use to pull in the sales. Everyone can relate to a snotty nose after all. The mucus-producing processes within the nose are set into overdrive and before long, a person suffering from a URI ceases to be human transforms into a snot making machine instead.
It’s important for people to remember to blow their noses properly when they’re full of snot, as judging by what normally ends up on the inside of the tissue, there aren’t many people who would like to sniff all that green stuff right back up into their heads. For adults, it’s easier to manage, but for children, the demands of play and their inherent thirst for learning, meaning that they can sometimes wander about with a snot trail from nose to lip.
