What is Mucus?
Mucus lines the moist surfaces of your body (e.g., lungs, mouth, stomach, etc.). Our bodies are constantly making mucus. It filters out materials that you breathe in through your nose, such as dust. “Anything that you breathe in gets stuck in the mucus, like flypaper.” – Dr. Andrew Lane, an ear, nose, and throat expert at Johns Hopkins University
Mucus has several names, like snot and phlegm. It can come in a range of colors. “People think about it as something you’re supposed to cough up and get out. That it’s a bad thing. But in truth, mucus really is the interface between you and the outside world.” – Dr. Richard Boucher, a lung expert at the University of North Carolina.
When does Mucus become a problem?
You notice Mucus becoming a problem when you’re making too much of it. Infections, allergies, and histamine are common causes of excessive Mucus and changes in its consistency.
What are the common signs of excess mucus that may need relief?
According to the MedlinePlus (an official U.S. government website), common signs of excess mucus that may need relief include:
- A persistent cough
- A constant need to clear your throat
- A stuffy, blocked, or runny nose
- A feeling of mucus running down the back of your throat
- Difficulty sleeping due to congestion
- Headaches or facial pain/pressure
- Reduced sense of smell or taste
- Wheezing or shortness of breath
