You probably only notice your mucus when you’re sick. But there’s more to mucus than what you feel when you have a cold or the flu.
Mucus helps keep you healthy. Your nose and throat glands make up to 2 quarts of it every day.
It’s a moist film that helps keeps your nose from drying out.
Mucus also helps shield your lungs from dust, bacteria, exhaust fumes, cigarette smoke, viruses, and other intruders.
“When we’re healthy, we don’t even know it’s there,” says Jayakar Nayak, MD, PhD. He is an ear, nose, and throat specialist who studies mucus at Stanford Hospital and Clinics in Palo Alto, Calif.
But when you’re sick, it’s a different story.
Of course, if you are concerned about the color of your snot, it is always best to consult a doctor. Check out the infographic below.
