Sputum plays a very important role in our body and, contrary to its appearance, can tell us a lot about the current state of health. It is produced by body tissues that secrete mucus in the mouth, nose, sinuses, larynx, lungs, and digestive tract. The phlegm is protective and does not dry out the tissues. It also has a function that is most useful in the fall-winter period: it is an excellent trap for bacteria and viruses that are destroyed by enzymes.

Our body produces about 1-1.5 liters of mucus every day, and this is important for our body. There is some speculation that the color of the phlegm can determine our health, but this is not one hundred percent confirmed, since many factors can influence the color of the mucus. However, this is one of the most proven methods, and without much effort we can see what the color of the phlegm says about our health:

Sputum: Bright color

When we are dealing with transparent mucus, we can be sure that there are no signs of inflammation in our body. Drink plenty of water to stay healthy. A well-hydrated body can protect itself from disease even at the most critical moment. Always keep the mucous membranes in your nose and mouth moist. To rinse your nose, you can use seawater, which is sold at the pharmacy.

Sputum: White or grayish tint

There is some speculation that eating a lot of dairy will make mucus white or even gray, but there is no scientific evidence for this. It is true that dairy products tend to thicken mucus, making it difficult to get rid of it. When we notice that the mucus is white or gray, we can be sure that it is coming from the sinuses. These may be the first signs of inflammation that should not be taken lightly.

Sputum: Yellow or green

If the discharge is yellow or even green, you should not panic right away. This may be a sign of a slowly developing infection in our body. Such symptoms most often accompany a cold or flu; when sucking on the nose, we can observe a greenish tint of mucus. If the situation with green mucus is repeated quite often, it is worth checking with a specialist doctor if you are allergic to something. Sometimes the green or yellow color of mucus can be the result of seasonal allergies and has nothing to do with viral or bacterial infections.

There are several possible reasons that directly affect the color of the discharge. If you smoke, the mucus may change from clear to dark yellow or even brown. The reason is the toxic substances contained in cigarettes, which negatively affect our entire body. However, if you are not a smoker, pay attention to the foods you eat. Certain types of beverages, such as coffee, chocolate and wine, can discolor your discharge.

Sputum: Pink and red

When the mucus is pink or red, we can see a small amount of blood. Blood often comes from blood vessels in the nose. However, a pink tint suggests that it is time to see a doctor, as these may be the first symptoms of pulmonary edema, tuberculosis, pneumonia and even cancer. In both cases, be sure to see a doctor.

Sputum: Black color

Black mucus can mean that you’ve been in a polluted environment for a long time. Dirt, dust, soot and other unfavorable environmental factors can affect the color of the mucus. However, if the problem gets worse and your discharge remains black for a long time, it could be a sign of chronic sinusitis.
