Yellow mucus does not always signify an infection. It's a common misconception. Mucus changes color based on many factors, including dryness in the air or minor irritations. Yellow mucus can signal that your body is defending against irritants, like allergens, or fighting a cold, but it's not a definitive sign of bacterial infection. An increase in mucus volume or a persistent change in color accompanied by other symptoms might warrant a visit to a healthcare professional for a thorough assessment.
