Do you know "what" a runny nose does?

A runny nose, while sometimes bothersome, is an important part of the body's natural defenses. When viruses, bacteria, or allergens enter the nose, the mucous membrane triggers the production of more mucus to remove them as quickly as possible.

This excess mucus helps flush out unwanted guests and prevents them from further penetrating the respiratory system. Additionally, mucus contains defensive substances, such as enzymes and antibodies, that help fight the threat.

Instead of immediately fighting it, it's important to understand that a runny nose is a sign that our immune system is working—and trying to protect us.
