The Skinny on Snot: What Your Child's Mucus Says About Their Health

Sep 25, 2023

It’s kind of gross to talk about, but you can learn a lot from snot. While mucus may be a bit of an annoyance, it plays an important role in your child’s body. Mucus lines organs with a protective layer, keeping dust and dirt out to help fight off infections. But not all mucus is the same. Different colors can mean fungal infection or other serious health issues. And mucus from allergies is different from that of the common cold. Pediatrician , explains what the different colors of mucus coming out of your child’s nose really mean, and when you should visit the doctor.

It's kind of gross to talk about, but you can learn a lot from your snot. I'm and I'll give you the skinny on snot today on The Scope.

It's cold and flu season again and kids are virtual germ factories. So this means a lot of snotty noses are in your house, probably. But what do the different shades of mucus coming out of your child's nose really mean?

Colorless

If your child is producing more than usual, they may have allergies or a mild cold. Stringy mucus is allergy mucus. Liquid-y mucus is viral mucus. If your child has whitish mucus, it also could be the start of a cold. If your child has white mucus for more than two weeks, is a teenager, or develops sinus pain, fever, or other symptoms, they could be getting an infection.

Yellow

When your child has yellow snot, it's because the white blood cells are fighting off the infections. The good news is their body is doing what it should. The bad news: your child's probably getting sick and it may clear on its own, but if not, your child needs to visit the doctor.

Green

When your child's snot is green, it means the white blood cells are working overtime to fight off their infection. Your child may need antibiotics to help fight off the infection if your child has green mucus and that mucus persists for more than 10 days.

Pink or Red

If your child has pink or red mucus, that means they've got blood in their mucus and it's often due to irritated nasal passages. It's common in dry climates and high elevations, like Salt Lake City, and for asthmatics and people with nasal allergies to have blood in their mucus because mucus irritates everything it touches. And when children have dry noses, the tiny capillaries in their noses pop open easily.

Brown

If your child has brown mucus, you can thank air pollution. If the air quality is poor, your child may have flecks of debris in their nose and in their snot. This is a good thing, though. It means the mucus is doing its job of getting the pollutants out of your child's nose. If the air quality is poor, limit your child's time outdoors. Also, make sure they're not around anybody using tobacco.

Black

If your child has black snot, that's a warning. Your child may have a serious fungal infection or other health issue and you need to take your child to the doctor right away.

White

While mucus may be a bit of an annoyance, it plays an important role in your child's body. It lines their organs with a protective layer, keeping dust and dirt out, and it helps fight off infections.

When to Take Your Child to the Doctor

While you don't need to worry about colorless, white, or even yellow snot if your child's only been sick for a few days, if your child has green, red, or any other color snot and it's been going on for more than two weeks, please have them seen by their pediatrician.
