When a person has a cold, why do both nostrils get clogged?

When winter comes, the temperature drops suddenly, and many people suffer from colds because they do not prevent cold air in time. Once you have a cold, you will have nasal congestion, which is also a symptom of helplessness. So, why do you have nasal congestion after a cold?

That's because everyone's nose is like a house, and this house has doors on both sides, and drawing a dividing line from the middle of the human nose, it becomes two rooms on the left and right, and at the same time, there are turbinates hanging on the side walls of both rooms, and they are curled. So, this room is the human nasal cavity.

The front of the nasal cavity is also the nostrils, and behind it is the pharynx of the human body. The pharynx is not only responsible for swallowing, but also responsible for the body's breathing. There is a layer of mucous membrane in the human nostrils, and when the human body has a cold, not only the capillaries will dilate, but the nasal mucosa will also become inflamed, which will increase the secretions in the nose, thereby hindering the flow of gas in and out, and the nose will not breathe.

So, of course, when a cold has nasal congestion, why is it that only one is blocked under normal circumstances?

1. Physiological turbinate cycle.

In a normal state, people who do not suffer from colds, when they are active, the body will continuously ventilate the two nasal cavities for the blood oxygen required for human body functions. However, if it is inactive, the two nasal passages are alternately ventilated. In medicine, this type of condition is known as a physiological turbinate cycle.

When you remove the structure in the nasal cavity, you will find that there will be a lower turbinate in each nasal cavity, and the inferior turbinate is a cavernous body, which will expand or contract with the changes of human life. As a form of alternating hyperemia, the normal alternating time is seven hours.

This change in the menstrual cycle occurs so that during sleep, when the side rests, the inferior turbinates of the lower nasal cavity will be congested and expanded, so that the human body is hindered from breathing. This is also why the side of the nose will be blocked when you have a cold.

2. Nasal cycle.

Another reason why only one nostril is blocked when the nose is congested is that the two nostrils of the person themselves are one in the state of being in a state of passage and the other is in a state of not being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of Whether you have a cold or not, the two nostrils work alternately, and when one nostril works, the other nostril rests, which is the nasal cycle.

In other words, the nostrils at work are completely open, and the nostrils at rest are blocked by some and are not completely open.

In short, when you have a cold and nasal congestion, you can consult a doctor and make relevant decisions, and at the same time, you should also have a good work and rest habit, combining work and rest.

When a person is sick, due to the body's immune response, a lot of body fluids and waste products are produced through the nostrils and feces, so the nostrils contain body fluids and waste products that cause blockage.

Because when we have a cold, some of our nerves are not able to control our nose well, and at the same time, there will be some substances that form nasal discharge.

Because this is the basic symptom of a cold. Because the nasal mucosa is blocked.

When a person has a cold, why is one nostril blocked, but the other is normal?

In general, when we always have a cold, one nostril is blocked and the other nostril can be ventilated, which may be the result of our physiological evolution, so that we can avoid the pain caused by not ventilating both nostrils, especially when sleeping with the mouth open for a long time.

People have two nostrils, but these nostrils are not symmetrical. At any given time, one nostril is out of its usual state, and the other is a little narrower, probably every few hours. This is caused by a change in the position of the bones in the nasal cavity, which belongs to the autonomic nervous system and cannot be consciously manipulated.

Under normal circumstances, people do not feel the nasal cycle, although the air intake in the two nostrils is different, but they are both very large, and do not give people a sense of breath-holding. However, if the swelling caused by a cold is not too severe, there will be a state of half blockage and alternating cycles, and both of them will be blocked when they have a severe cold, and the follow-up has nothing to do with it.

Nasal congestion is characterized by the size of the turbinates, the deviation of the nasal septum, the degree of nasal mucosal congestion and edema, and the presence of new nasal organisms. It's also possible that when you're on your side, the nasal secretions will flow to one side and the other side will be relieved.

It is difficult for normal people to feel nasal resistance, but what we feel is normal ventilation. This nasal cycle is regulated by autonomic function and is not regulated by subjective consciousness, so it is difficult to feel. When you have a cold, that is, acute rhinitis, nasal mucosal congestion and edema, and increased nasal resistance, you feel that the nasal cycle exists, so you feel the symptoms of alternating nasal congestion and the nasal congestion under the side when sleeping!

In everyday life, this cycle works all the time. You'll only notice when your nose is more clogged than usual, when you have a cold. The two nostrils are originally one through and the other is not very passable, because the two nostrils are always taking on the workload alternately, and a round of alternation will start every two and a half hours on average, and each nostril has its own time to go to and from work.

And their working hours are staggered, which is called the nasal cycle.

I think it's related to everyone's physical factors, and it's also related to everyone's condition, because there are a lot of people who have strong physical fitness, and some people have very poor physical fitness, so there will be this situation.

This is very normal, because after a cold, the body will be very uncomfortable, and the body will secrete something, so this situation will occur.

Because the nostrils are asymmetrical, there is a clear difference between the two, which also helps us breathe.

It's a physiological function of humans that can guarantee normal human breathing, so that's how it happens.

It may be rhinitis, like this case, you can go to the hospital to let the doctor check whether it is rhinitis, if you prescribe the right medicine, you will not have nasal congestion in the future, if it is not rhinitis, you can make a professional judgment and choose the appropriate method to avoid nasal blockage.

It is most likely due to a cold, rhinitis, or a problem with the nasal mucosa.

It may be a bacterial infection, or the external environment may be too harsh. It may be rhinitis, it may be nasal mucosal hyperemia, it may be edema.

Why is my nose always blocked when I have a cold, and I think it makes sense after reading it!

According to the U.S. National Library of Medicine, "nasal circulation" occurs several times a day, and only when one of the noses is clogged does it catch your attention. To open one nostril and close the other, the body automatically engages around the nose.

Increased blood flow can cause congestion and blockage on one side of the nasal cavity, which will be switched to the other side after 3-6 hours. "Jennifer Shu said so? "This congestion will be more noticeable when lying down, and you can feel it clearly if you tilt your head to one side."

This cyclic process has long been thought to help with the sense of smell. Studies have shown that when the airflow passes through the nasal cavity quickly, the entrained odor can be better collected.

If one side of your nose is open and the other side is tightly closed, almost all odors will be collected. At the same time, your other side of the nose will also be rested at this time.

And when you're sick, the cycle becomes unbearable, as the nasal passages, which are normally "closed", become significantly more congested, causing discomfort.

So, the next time you feel that one nostril is not breathing, understand that this is a mechanism created by the body to ensure the quality of the sense of smell. That way, maybe you won't be so upset.

If the sinusitis is mild, it is recommended to be conservative**, and oral antibiotics can be used to reduce inflammation and relieve symptoms; It is difficult to achieve the disease with drugs, and it can also be performed with acupuncture**. Also, pay attention to the warmth of the nasal cavity, drink more hot water to keep the nasal cavity moist, exercise to improve the body's immunity, and prevent colds. Notice the above points should gradually get better.

How can so many bad reviews still be left in the trap.

Why is there always a nostril that is not breathable when I have a cold and nasal congestion?
