Snot: it’s not glamorous, but it’s essential. This sticky substance, also known as nasal mucus, plays a critical role in protecting your health, but it probably doesn’t enter your mind on most days—until it comes out a strange color. Let’s take a look at how snot protects your health and why it may change color from time to time.
What Does My Snot Do?
Snot may seem like an annoyance, but it’s a hardworking part of your immune system. Nasal mucus moisturizes your nasal passages to prevent dryness and irritation. It also acts as a filter, trapping bacteria, viruses and other harmful particles you might breathe in. Think of it as your body’s built-in air purifier.
Decoding the Colors of Snot
Snot can come in many colors, and each color means a different thing:
- Clear. Clear mucus is a good sign—it means your nasal passages are functioning as they should. Clear snot is primarily water. It helps keep your nasal passages clean and free from germs. Clear snot usually runs after a spicy meal or a walk around North Spartanburg Park on a chilly day.
- White. When your mucus turns white, you likely have a minor infection causing congestion. The white color appears because the mucus has lost moisture and become thicker, often due to inflamed nasal tissues.
- Yellow or green. If your snot shifts to yellow or green, it’s a sign your immune system is kicking into high gear. White blood cells are sent to fight off infections, and as they break down, they give mucus its yellow or green hue. Green snot indicates that your mucus has thickened and become concentrated with these cells. While it’s a sign your body is fighting back, don’t hesitate to consult your ENT specialist if green snot or other symptoms linger.
- Red or pink. Red or pink snot is usually caused by minor bleeding from your nasal passages. This can happen if you’ve been blowing your nose frequently, picking it or experiencing irritation from dry or cold air. Pinkish mucus indicates small blood vessel damage, while darker red snot points to more significant irritation. If you experience ongoing nosebleeds or heavy bleeding, seek medical assistance.
- Brown or black. Brown or black mucus is often the result of inhaling dirt, smoke or other debris. It can be common if you’ve been around pollution, construction sites or smoky environments. While it’s not typically harmful, wearing a mask can help protect your nasal passages. Although uncommon, some black snot can indicate a fungal infection. If the color persists, consider consulting a specialist.
