Snot's Different Colors And What It Means For Your Health

Snot, the mucus that comes out of your nose, may seem unimportant. But the color of your snot can tell a lot about your health.

This vital piece of information does not provide a clear-cut diagnosis of any health disorder. It may, however, clue in on what is happening inside the body.

Clear snot

The mucus that is devoid of any color is considered normal. The mucus is secreted in large amounts by the body, and helps in keeping the nasal passage lubricated and protected from germs. Snot consists of protective proteins and salts, with water. This moisturizing layer keeps dehydration at bay, and staves off pathogens like bacteria and viruses.

The little hairs in the nose move these microbes down to the stomach, where the threat is neutralized by acid, according to ScienceAlert.

The mucus is present not just in the nose, but in every moist surface of the body, such as the lungs, sinuses, mouth, stomach, intestines, and even the eyes, the outlet reported.

If the amount of clear mucus increases, it may mean that you're suffering from allergies or a cold or flu.

White snot

White mucus may be due to a nasal infection, allergies, or dehydration. It might also mean that the nasal passage is irritated and swollen, which, in turn, restricts mucus flow and dries it out, according to the Business Insider.

The immune cells, while fighting whatever is irritating the nose, release molecules that give the mucus its cloudy texture.

One might have a runny nose during this time. This is also said to be the phase, where one is likely to be the most contagious.

The myth that milk is responsible for giving the snot its white color is untrue.

Yellow snot

During an immune response, the white blood cells spring into action and mount an immune attack on the invaders. These white blood cells are later discarded by the body through the mucus, among other things. The discarded cells can stain the mucus yellow.

This, however, does not warrant an antibiotic to treat it. Infections are commonplace, and, in most cases, the body can fight off the microbes on its own.

Green snot

Green mucus may be because of a large build-up of dead white blood cells. If the green snot is accompanied by a fever or feeling of nausea, one should see a doctor for a clear diagnosis.

Pink or red snot

Red or pink mucus indicates the presence of blood in the nose. The blood may be due to allergies, infection, and incessant blowing or rubbing of the nose. Physical trauma can also turn your mucus this color.

Dry air may be yet another reason for the color change of the snot.

Brown snot

Brown-colored mucus may be due to dried blood or even dirt. The blood in the nasal passage dried and turned brown. It may also be because of dirt, dust, or from cigarette smoke, snuff, or a spice.

Coughing brown mucus may be a sign of bronchitis and one should go see a doctor in this case.

Black snot

Black mucus is common among smokers, especially due to underlying lung disease. The color of the snot may also be because of inhaling dirt or dust, or after smoking cigarettes or marijuana.

Black mucus may also indicate a serious fungal infection, in case of a compromised immune system.

If you cannot find a possible reason for the snot to be this color, you should consult a doctor. Definitely see a doctor if you have a fever, chills, or difficulty breathing.
