Snot might not be the most glamorous topic, but it plays a crucial role in keeping your body healthy. That sticky, often inconvenient mucus traps germs, dirt and other harmful particles, stopping them from invading your respiratory system. Beyond its protective role, colorful snot can provide important clues about your body’s health and what’s happening inside. Let’s take a look at what each color means.
White Mucus
Healthy snot is clear and watery. Thicker, white snot may mean:
- Congestion. White or cloudy mucus often indicates mild congestion. This happens because your nasal tissues are swollen, slowing mucus flow and making it thicker as it dries.
- Potential causes. Colds, sinus infections or even dehydration can cause this change. White mucus will usually clear up with the infection causing it.
Yellow or Green Mucus
Yellowish or green mucus often indicates:
- Infection. Yellow or green snot is a sign your body is fighting off an infection. White blood cells rush to the area to combat germs, leaving behind a color change as they finish their work.
- When to worry. Green mucus that persists or comes with a fever might mean it’s time to see a healthcare provider. It could signal an infection that needs treatment.
Red or Pink Mucus
Red or pink mucus might indicate:
- A nosebleed. Red-tinged mucus usually means there’s a bit of blood in your snot. This is often caused by irritation, like blowing your nose too hard or dry nasal passages.
- When to seek help. A steady stream of red mucus or a productive nosebleed lasting more than 10–15 minutes warrants medical attention.
Brown or Black Mucus
Brown or black mucus may indicate:
- Dirt or debris. Dark-colored mucus often points to inhaled debris, like dirt, dust or smoke.
- When to act. If you’re exposed to these irritants often, wearing a mask can help protect your respiratory health. Persistent brown or black snot could also indicate a fungal infection in rare cases, so monitor your symptoms closely and seek help from your ENT provider if it continues for more than a few days.
