What the color of your snot can reveal about your health
Open your tissue, if you dare. The color of your snot can reveal a lot about your health.
Our noses are lined with mucus membranes that secrete snot to help keep our tissues healthy and trap dirt, cleaning the air we breathe on its way to our lungs. The nasal discharge they produce repels infections, lubricates the skin, and keeps viruses from entering our bodies.The color of the snot in your nasal passages is often determined by how many white blood cells are circulating in the nostrils. That's why taking a look (as gross as it might sound) can reveal useful information about how healthy we are.
Of course, the color of your snot isn't an absolute diagnostic test. Most of the colorful clues our noses give us are not reason enough, on their own, to call a doctor, yet the rainbow of options can serve as a first hint about what's going on inside our bodies.
Given that we produce and swallow about 1.5 quarts of nasal mucus every day, we are filled with a lot of sticky data to draw from.
