When you have a cold or an allergy, you will definitely feel uncomfortable with your nose. The reason is, you will be busy cleaning the nasal fluid or mucus that flows non-stop even though it has been expelled many times. Actually, where does snot come from? Can snot be a sign of problems with your body? Read on for the following reviews, yes!
Unique facts about snot
Snot is mucus or fluid produced by the mucosal glands that line the respiratory tract. These passages include the nose, throat, and lungs. The body produces mucus continuously, even reaching one to two liters of mucus every day.
Interestingly, you don’t realize that you swallow your nose every day when you don’t have the flu. This occurs when the fine hairs on the nasal cells (cilia) move mucus down the back of the nasal passages to the throat and swallow it.
But make no mistake, nasal mucus has important roles for your body, including:
- Keep the inner lining of the nose moist so it doesn’t dry out
- Traps dust and other particles while breathing
- Fight infection
- Moisturizes the inhaled air so that it becomes more comfortable when you breathe
Where does snot come from?
Normal nasal mucus has a very thin and runny texture. Increased production of mucus is one of the ways the body responds to foreign substances that enter the body. The reason is that the mucus acts as a barrier to infection by cleaning the nasal organs from particles that cause inflammation.
When the mucous membrane is inflamed, this can make the mucus texture thicker. This condition tends to make you uncomfortable when you have the flu . Causes of inflammation of the mucous membrane can be due to infection, allergies, irritants, or vasomotor rhinitis.
When you have a fever or chills, your nose becomes more susceptible to bacterial and viral infections. The flu virus will trigger the body to release histamine, a chemical that triggers inflammation of the lining of the nose. This is why mucus production becomes increased and thickens.
However, thickening of the mucus texture is not always bad. The reason is, this thickening makes it difficult for bacteria to settle in the lining of the nose. A runny nose is the body’s way of moving bacteria and other substances that are not needed to get out of the nose.
Allergic reactions to dust, pollen, mold, animal dander, or other allergens can cause inflammation of the mucous membranes. The mast cells in the body secrete histamine which causes sneezing , itching and nasal congestion. Furthermore, the nose will discharge excessively mucus.
3.Irritants (causes irritation)
Various non-allergen irritants can trigger inflammation and cause a short-term cold sensation, for example when you are exposed to cigarette smoke or chlorine after swimming. Eating very spicy foods can also cause temporary inflammation of the nasal membranes. Although harmless, it does lead to excessive mucus production.
4. Vasomotor rhinitis
Have you had a runny nose for a long time? It could be that you have vasomotor rhinitis . Vasomotor rhinitis is a condition when the blood vessels in the nasal membrane become swollen so that mucus production becomes more. This can be triggered by allergies, infections, irritation from the air, and other health problems.
Crying is the only trigger for mucus production that has nothing to do with infection, allergies, or other medical conditions. When crying, the tear glands that are located under the eyelids will produce fluid ( tears ).
Some of the tears will flow out and flow down the cheeks. However, some of it will drain into the tear duct located at the corner of your eye. Furthermore, this fluid will mix with the mucus in the nose so that it is pushed out into snot.
What is a sign of dangerous snot?
Healthy or not in your body condition can be seen from the color of the snot . The color of the mucus usually tends to be clear and watery. If your mucus turns green or yellow, this could be a sign that a bacterial infection is developing in your body. This is because infection-fighting white blood cells contain enzymes that are green in color. If in large amounts, it can cause the mucus to turn green.
If you have experienced a red or brown discoloration of the nasal mucus, this is probably due to a ruptured nasal blood vessel. This can happen when the lining of the nose is too dry or there is a sore from rubbing too hard.
However, a change in the color of your mucus does not always indicate a bacterial infection in your body. Therefore, immediately ask your doctor for a more precise diagnosis.
