Your mucus color might be warning you about your health 👀👃

Added: 2026-05-18

The color of nasal mucus can indicate different health conditions: clear mucus suggests normal health or mild allergies, white indicates congestion or early cold stages, yellow signals the immune system fighting an infection, green suggests a stronger bacterial or viral infection, brown results from dust, pollution, or dried blood, and gray or black may indicate heavy pollution or inhaled particles. While occasional changes are normal, persistent or severe symptoms should be checked by a doctor.
