Why is it easy to have a runny nose when it is cold? What should rhinitis patients do?

Subjectively, we ordinary people know that "rhinitis" is a disease. "Rhinitis is not an inflammatory disease of the nasal cavity!" As we all know, due to different causes, rhinitis also has many classifications, such as infectious rhinitis, allergic rhinitis, vasomotor rhinitis, dry rhinitis, drug rhinitis, atrophic rhinitis and so on.

There is a kind of rhinitis that many people don't know. This kind of rhinitis is vasomotor rhinitis. Because this kind of rhinitis has little impact on our health, good recovery, short course of disease and no impact on work and life, it generally does not attract everyone's attention. However, this kind of rhinitis is common. It is a disorder of the autonomic nervous system. When encountering cold and hot stimulation and bad air stimulation, a lot of runny nose, itchy nose and continuous sneezing may occur. When these bad stimuli disappear, the nasal cavity will soon return to normal.

There is no effective cure for this kind of rhinitis, only regular physical exercise is recommended to increase resistance. Be careful not to suddenly go in and out of the cold and hot environment. Regular nasal massage, such as washing your face with cold water for a long time, is better. Try to avoid contact with known allergens. Keep warm when you have an attack.

Rhinitis is a manifestation of local congestion and edema caused by chronic inflammation that stimulates nasal mucosa for a long time. Rhinitis can clear nasal mucus mostly because inflammation or allergy stimulates nasal mucosa.

There is only a small amount of mucus in the normal nasal cavity, which is moist to maintain normal physiological function. Pathological changes in nasal cavity will cause changes in the nature and quantity of nasal secretions. Because the nasal mucosa is stimulated by cold, the sensitivity of different nasal mucosa is different A few people will shrink their pores because of the stimulation of cold air. When the pores are closed, the water vapor originally emitted from the pores cannot be emitted normally. If there is no way to discharge it, it will be squeezed into the respiratory tract. If it is too crowded, it will condense into liquid and form a runny nose in the nasal cavity, causing a runny nose. A small amount of cold air and irritating food can cause involuntary runny nose.

People can strengthen their resistance and reduce the sensitivity of nasal mucosa by strengthening physical exercise, especially aerobic training, washing their faces with cold water and taking a cold bath, thus alleviating the symptoms of runny nose.

Many people start to have a runny nose as soon as the weather is cold, and when the cold wind blows their noses, they stay. Pockets full of toilet paper, a few days later, the nose became like a clown, red and swollen. Why do patients with cold air rhinitis have a runny nose?

As we all know, the nose can make the breathing air warm and moist. Breathing through the nose in a cold environment, although the inhaled air is cold and dry, will not cause damage to lung cells passing through the nose.

When cold air passes through the nose, it will stimulate the nerves in the nasal cavity and send signals to the brain. Then, under the instruction of the brain, it will begin to dilate blood vessels and increase the blood flow of the nose, thus heating the inhaled cold air. At the same time, the nose will secrete more liquid to moisten the incoming cold air.

Because some nasal mucus will evaporate and some will turn into nasal mucus, it is generally not seen that nasal mucus flows out of the nasal cavity. But if the nose overreacts and produces too much liquid, it will flow out of the nose.

It should be caused by rhinitis, mostly caused by allergies, infections, hot and cold air stimulation, etc. Rhinitis is mainly caused by inflammation of nasal mucosa and submucosa, virus and bacteria infection or injury under the action of irritants.

The typical symptoms of rhinitis are usually stuffy nose, watery nose, itchy nose, sore throat, cough and so on. In severe cases, dizziness and headache appear. When inflammation occurs in the nose, a large amount of nasal mucus can turn yellow due to infection, cause cough when it flows through the throat, and cause nostril bleeding when it is excessive.

Rhinitis caused by a cold is generally allergic rhinitis, also known as allergic rhinitis. The treatment of allergic rhinitis is mainly based on standardized drugs, such as chlorpheniramine, Cimin, Kairuitan and Biyankang. The local treatment can be intranasal spray of cloisonne dipropionate aerosol or nasal drops of ephedrine and dexamethasone. , can effectively relieve symptoms.

Allergic rhinitis caused by sneezing, clearing nose or cold air allergic reaction in cold weather. In this case, it is necessary to actively take medicine for symptomatic treatment.

By the way, a runny nose when you have a cold is actually one of the symptoms of rhinitis. General allergic rhinitis is more common. In case of wind, cold, sneezing, etc. Drug treatment and daily health care are needed to improve this situation. It is suggested to adjust diet, pay attention to diet, and exercise properly at the same time to improve the body's repair ability. Diet should be light, easy to digest and absorb, high in protein, vitamins and minerals, and high in calories. Avoid eating animal fat and fried food; It is not advisable to eat high-fat food; Avoid spicy food; Such as crucian carp seeds, cream and fried dough sticks are not suitable. It is also necessary to avoid staying overnight, excessive fatigue, heavy physical activity and cold protection.

Why does rhinitis have a runny nose when it meets cold air? The role of the nose is to make the air we breathe warm and moist, and then enter the lungs to avoid damaging the cells in the lungs. Breathing through the nose in a sub-zero environment, the air temperature deep in the nose is actually around 26℃, and the highest temperature can reach 30℃. The air humidity here can reach 100%, although the air we just inhaled is cold and dry. Therefore, the nose plays an important role in the process of air flowing into the lungs.

When cold and dry air passes through the nose, it will first stimulate the nerves in the nasal cavity and send this signal to the brain. The brain immediately began to deploy dilated blood vessels to increase blood flow to the nose to warm the cold air. At the same time, the nose will be instructed to secrete more liquid to moisten the incoming air. It is estimated that a person may produce 300-400 ml of liquid a day. Under normal circumstances, these nasal mucus flows to the pharynx along the direction of nasal mucosa cilia movement, a small part evaporates and a small part becomes nasal stones, so it is generally not seen to flow out of the nasal cavity.

No matter in the process of heating or humidifying the air, the temperature of the nasal cavity will drop again because of the evaporation of water, so the nose will feed back to the brain and apply for increasing the temperature. The brain will instruct to increase the blood supply and the amount of liquid produced in the nasal cavity again. This process goes on and on, and it is always difficult to achieve balance. If the nose overreacts, it will produce too much liquid, just like a clear stream flowing down the nostrils, which becomes a menacing snot.

Rhinitis has a runny nose when it meets cold and wind. Choose pure Chinese medicine rhinitis essential oil to relieve symptoms until it is cured.

The essential oil of saline nasal washing and nasal brush have broad-spectrum bactericidal and bacteriostatic effects. Absorbed by mucosa, anti-inflammatory and bactericidal. Usage: Use 1.2 times a day, with acupoint massage, and often massage the nose up and down. Pressing Xiang Ying (located at the midpoint of the outer edge of the nose, in the nasolabial groove) is helpful to relieve the symptoms of allergic rhinitis. This method can promote blood circulation to a certain extent, reduce local congestion, enhance immunity, and is good for relieving rhinitis symptoms.

Don't relax carelessly after the attack of allergic rhinitis. You can usually keep one more bottle. Sometimes the initial rhinitis is not very serious. It's just that if we don't care, it will recur even more. To avoid recurrence, you can only prepare in advance. Wipe it if there are signs. It can also play a preventive role.

Is cold and runny nose allergic rhinitis? In life, we often think that sneezing and runny nose is rhinitis, but it is not.

Clinically, it is generally considered to be vasomotor rhinitis, which is a highly reactive nasal disease caused by neuroendocrine disorder of nasal mucosa blood vessels and glands.

Frequent contact with cold air, sudden temperature change, humidity, etc. That is, paroxysmal sneezing, accompanied by more watery nasal discharge, patients can often clearly tell the cause, which may also belong to reversible rhinitis.

If the symptoms similar to allergic rhinitis often appear after the air conditioner is thoroughly cleaned in summer, it is necessary to consider that it is vasomotor rhinitis, which is caused by cold and heat stimulation. If so, it is necessary to strengthen its adaptability. Proper outdoor exercise can help this phenomenon very well.

In the view of Chinese medicine, it belongs to the category of yang deficiency. Patients with runny nose and sneezing after being stimulated by cold air are generally afraid of cold and wind, which is a typical yang deficiency. The reason why they have a runny nose and sneeze when they meet cold air is because they are born with yang deficiency and exogenous cold. The pungent-warm method of relieving exterior syndrome, such as Guizhi Decoction, Mahuang Decoction and Fang Jing Granule, can be improved rapidly.

Those patients who are prone to relapse are often due to insufficient yang and healthy qi, or poor immune function as western medicine says, and often need to warm yang or replenish qi, which improves the immune function of patients. After the physique is enhanced, it is naturally not easy to sneeze with a runny nose when encountering a cold.

Of course, the constitution is different. For those who have been ill for a long time, it is still necessary to consolidate and persist in treatment for a period of time. A long illness requires patience. Only by persisting in changing physical fitness, all symptoms will naturally be solved. This is to strengthen the body and eliminate evil, including healthy qi, and evil cannot be done.

Sneezing, runny nose and itchy nose are common in allergic rhinitis, and hormone spray treatment is given.

Normal nasal mucosa, whether cold or hot, is at a relatively constant thickness and will not expand with heat and contract with cold, so it will not have a runny nose when the external environment changes.

Patients with rhinitis often say that when they arrive in an air-conditioned room in summer or it is cold in winter, their noses can't control the flow of clean water and sneeze, which is caused by the high reactivity of allergic rhinitis. Cold air in the nasal cavity indicates that the liquid was in the nasal mucosa at that time, otherwise it is impossible to transport water to the nasal mucosa through the blood circulation system in a few seconds. Because of the principle of heat swelling and cold contraction, the accumulated water in nasal mucosa is squeezed out in a few seconds, just like the water in sponge, which also shows that the mucosa of rhinitis patients is in a subacute and highly swollen state.

There is cold in your body, which leads to the same qi, and the external cold moves the internal cold.

In winter, due to the cold climate, the blood circulation of nasal mucosa is disturbed, the blood vessels contract first and then expand, the mucosal tissue becomes more swollen and thickened, the ciliated cells of nasal mucosa fall off, and the secretion of glands increases. Therefore, patients feel that the nasal congestion is aggravated and persistent, the nose is increased, and the sense of smell is further reduced.

If the environment is warm and humid, it can improve the blood circulation of nasal mucosa, protect the epithelial cilia of mucosa and reduce the burden of nasal mucosa. So rhinitis patients will feel very comfortable in warm spring and summer.

How to do rhinitis in winter?

At the same time, you should avoid catching a cold when you go out, especially to avoid the nose being stimulated by cold air. Therefore, patients need to wear masks and clothes. Some patients may also need to use oral drugs to treat rhinitis.

Usually, you can wash your nasal cavity with normal saline, keep warm and exercise more to prevent colds.
