What Is A Cold And What Is It For?

A runny nose is a sign that the body is functioning properly. This sticky, sticky substance of various colors plays a very important role in protecting the body.

Everyone knows what a runny nose is , but few people know what it actually is and how it works. The average adult produces about a liter of mucus from the nose and twice as much from the throat.

Runny nose comes in a variety of textures and colors. Soft and hard, white and black, green and yellow. Usually associated with dirt, its main function is to prevent many unwanted particles from entering the respiratory system.

One way or another, a runny nose tells us if the nose is working as it should. While the habit of picking your nose to remove sticky material is common, it is best to dry it with a tissue.

What is a runny nose?

Runny nose is the fluid that comes out of the nose. It is not the only mucus secretion produced by the body, but it is popularly referred to as mucus. Bronchial mucus is often called phlegm or coughing up.

Mucus is a sticky fluid that is secreted by epithelial cells in the nose and other organs. These cells have cilia, which are a type of hair. They move the mucus into the nostrils.

They have several functions, the most important of which are as follows:

• They have a moisturizing effect: they help to keep the nose and sinuses moist. This protects against irritation caused by rubbing against objects or particles.
• They act as a protective shield: the tissue of the nostrils and sinuses is quite thin and delicate. The mucus helps protect her.
• They form a protective barrier: they help to capture and expel foreign particles that enter the nose, such as dust, pollen, bacteria and viruses.

The function of a runny nose can be summed up as a defense mechanism against external factors that can enter the body through the nose. They are essential in the fight against allergies and colds.

How does a runny nose arise?

Runny nose is produced inside the nose and is essentially a substance that contains water, proteins, certain chemicals, and salt. It has a sticky and sticky consistency, which allows it to trap harmful substances from the environment.

Most of the mucus produced by the nose and throat is mixed with saliva and swallowed. Some stays in the nose. When you sneeze or blow your nose, mucus is expelled. Otherwise, it stays in the nose and dries up.

If a person has a cold, the body produces more histamine. This is a substance that causes the nasal membranes to swell up and produce more mucus. This creates a thick layer of mucus that helps to protect the nasal tissues.

Also, when there is more mucus it has to be excreted more often as people blow their noses more often or sneeze more. This helps to expel the infectious agent. The same is true for allergies.

What is not a runny nose?

There are many popular myths about mucus. Myths, like myths, are not true, however. For example, they are said to be the brain cells that descend from the skull and reach the nose, which is not true.

Some also say that they are left over from the cerebrospinal fluid. It is also said that a green runny nose means a serious infection or that no runny nose means you’re clean. None of this has any scientific basis.

Why does runny nose change color?

One of the most striking aspects of a runny nose is that it changes color. In general, this is because of the substances that come into contact with it. We can find its various shades.

Transparent

This is the usual shade and the one that is considered normal. However, if it is dripping too much, it may be a symptom of a cold or allergic rhinitis. So a lack of color is not always a sign of no health problems.

Yellow or greenish

Yellow or greenish mucus is a sign of an infection that doesn’t have to be serious. It acquires this color because the immune system increases the production of defense cells called neutrophils.

These cells secrete enzymes that kill the infectious agent. One of these enzymes, peroxidase, gives mucus its color. A runny nose usually gradually turns from colorless to yellow and then green.

Red or brown

This color indicates that there is a blood component in the mucus. It is possible that some of the small blood vessels in the lining of your nose have ruptured, or that a minor injury was caused by sneezing or blowing your nose too often. This color shouldn’t worry us right away.

Black

This color of runny nose does not appear very often. Usually, if it turns this color, it is caused by inhaling smoke or soot. It could also be a sign that you have been breathing very polluted air.

Qatar is natural

A runny nose can be off-putting, but it’s actually a sign that everything is going well in your nose. Still, it’s best to educate children not to eat or swallow it. The point is not that it is toxic, but that it is a waste product of the body.

It is also important that neither children nor adults pick their noses as they can easily damage the tissues. It is best to blow your nose gently or use a nasal rinse to open it.
