Here’s what you can tell about your immune system by looking at the color of your snot.
Transparent. This mucus is basically water combined with proteins, salts, and cells that keep the nasal passages moist and trap particles. An excess of this type of mucus may result from allergies or early viral infection. The body can also respond to pathogens and irritants in a similar way.
White. White mucus is often a sign of nasal congestion. This usually signals the beginning of an infection.
Yellow. Yellow mucus means the body is actively fighting infection.
Green. Green mucus is the result of an increased immune response. It usually indicates a bacterial infection or viral pathogens.
red or pink. This mucus often occurs when the nasal tissues become too dry, irritated, or damaged. For example, this may occur due to excessive nose blowing or exposure to dry air.
brown or orange. Mucus this color is usually harmless but may indicate irritation or long-term inflammation.
Black. Black mucus is rare and may indicate serious problems such as a fungal infection or overexposure to pollutants (soot or cigarette smoke). This requires medical intervention.
