When you find yourself reaching for a tissue, only to discover that your mucus has taken on an unexpected hue, it can be alarming. You might wonder: what does this color mean? If you’ve been battling sinus issues and notice your nasal discharge is no longer clear but instead thick and green, you’re not alone. This change in color often signals that your body is engaged in a fierce battle against infection.<\/p>\n

Typically, when you have a sinus infection\u2014medically known as sinusitis\u2014the mucus becomes thicker and shifts to shades of yellow or green. But why does this happen? Mucus plays a crucial role in our immune response; it acts like a trap for allergens, bacteria, and viruses trying to invade our bodies.

Their presence indicates that your immune system is hard at work fighting off these intruders.<\/p>\n
