It's cold and flu season, which means a lot of snotty noses. Cindy Gellner, MD, a pediatrician at 麻豆学生精品版, explains what the different shades of mucus means.
鈥淲hile mucus might be a bit of an annoyance, it plays an important role in your body,鈥 Gellner says. 鈥淚t lines your organs with a protective layer, keeping dust and dirt out. It also helps fight off infections.鈥
Clear: Colorless snot is normal. If you're producing more than usual and it's stringy, you may have allergies. If it's liquidy, you may have a virus.
White: Thick, whitish mucus that lasts more than two weeks and includes sinus pain or a fever may indicate an infection.
Yellow: When white blood cells fight off infections, it makes your snot yellow. The good news: Your body is doing what it should. The bad news: You're probably sick. It may clear on its own, but if not, visit your doctor.
Green: Your white blood cells are working overtime to fight off an infection. If it's been 10-plus days, your doctor may prescribe antibiotics to help the fight.
Red: Pink or red mucus indicates blood, often due to irritated nasal passages. It's common in dry climates and high elevations, and for people with allergies or asthma.
Brown: Heavy air pollution can cause brown mucus. If the air quality is poor, limit your time outdoors. Tobacco use could also be the culprit.
Black: Black mucus may indicate a serious fungal infection or other health issue. Head to your doctor right away.
鈥淣asal saline rinses are one of the most effective ways to help your body fight against sinus issues and remove excess mucus,鈥 Gellner says.
