Let’s Talk About It – The Different Colors of Your Snot is Your Body Communicating

Snot. It is not the politest subject to discuss, but what most people don’t understand is that the color of it tells you what your body is dealing with. There is a spectrum of mucus colors your body can produce because of various reasons, and we’ll explore them.

To learn what the color of your mucus means, continue reading below.

A Thicker, White Mucus

Although this is typically nothing to be concerned about, it can be a good indicator that you’re a bit dehydrated. Further, it could mean that a sinus infection is beginning to form as the color comes from an increased number of white blood cells. If you have asthma and are experiencing a thick white mucus discharge, visit an asthma specialist for a check-up.

Pink or Red Mucus

This one is self-explanatory. The most likely reason why your snot is pink or red is because of blood. The most common reason for this is maybe blowing your nose too much when you have a cold or allergies. Too much irritation can cause your sinuses to become inflamed which can cause bleeding.

Yellow or Green Mucus

If you see yellow or green mucus, this is most likely from your body battling a virus, infection, or other allergens. The fight your white blood cells take on results in this color due to the unknown invader getting flushed out of the body.

Although it should return to a normal state soon enough, if it lasts more than 7 to 10 days and you are experiencing symptoms like congestion, sinus pressure, headaches, or fevers, it is time to see a specialist.

Brown Mucus

If the color on your Kleenex post-nose-blow has a slight tinge of brown, it could be dried blood. This usually isn’t too worrisome for it could be your sinuses are now healed and are expelling the scab. Inhaling too much dirt can also affect the color of the mucus.

Black Mucus

This can be tricky. It could be as simple as it being brown because of dried blood or dirt, or it can be a little more complicated. If you have a compromised immune system and are experiencing black mucus, it could be a fungal infection. If that is the case, it is recommended that you see a specialist as soon as possible.

Clear Mucus

We saved what is considered to be the best mucus color for last, no color at all! If your snot is clear, you’re what is considered to have normal nasal discharge. It is made up of mostly salt water with some antibodies and usually goes unnoticed throughout the day. If there is a sudden onset of clear mucus via a runny nose or the back of your throat, it is typically from allergies, but usually, nothing to be worried about.
