Decoding the Health Messages in Your Snot Color.

The color and consistency of your snot can be an early warning sign for health problems. Clear, thin snot is considered healthy, but if it is too white, it could signal congestion or that you are about to come down with an illness. A yellow or green color usually comes when you are most sick and happens when the body flushes out white blood cells that are used to fight infections. If the color in your tissue is red, pink or brown, it could mean there is damage to your internal nose tissue or something much more serious. Black snot could be an early sign of Mucormycosis, a rare and dangerous fungal infection.
