The method of physiological seawater nose washing is generally unfamiliar, but for some patients, otolaryngologists will recommend that they take the initiative to help treat the disease, and some patients with allergic rhinitis are among them.

As I said just now, the structure of our nasal cavity is quite crooked, and the barriers of nose hair, mucous membranes, and mucus block the harmful substances in the air, but there are some harmful substances that are "blocked" but not immediately discharged. But stayed in the nasal cavity.

Some of these staying harmful substances will be unconsciously discharged in the future with actions such as sneezing, but some will stay like this and become a chronic stimulus, and may even be inhaled into the deep respiratory tract. At this time, it is necessary to take the initiative to wash your nose.

What our otolaryngologist says about washing the nose is mainly to flush the nasal cavity with physiological seawater. Some people may ask, now that everyone knows PM2.5, is it effective for us to wash our noses? This is not conclusive, because there is no direct evidence to prove it, but many studies have shown that if saline is used to flush the nasal cavity, it will definitely have a clearing effect on airborne allergens and inflammatory secretions adhering to the nasal mucosa. of.

Therefore, washing the nose is suitable for people with colds, allergic rhinitis, sinusitis, and dry nasal cavity. Patients after nasal endoscopic surgery are also recommended to rinse the nasal cavity for more than 3 months. When the air pollution is serious, proper cleaning of the lower nasal cavity can also flush out allergens, dust and other pollutants inhaled into the nasal cavity, which plays the role of cleaning and moistening the nasal cavity, which is conducive to maintaining the normal physiological function of the nasal cavity and reducing allergies Irritation of the throat, trachea and bronchus by the original and contaminants.

 
How should you wash your nose?

 
How should you wash your nose? There are many opinions on the Internet.

 
For example, some netizens said on Weibo that they should blow their noses first to prevent the mucus and other mucus from blocking the water flow; then prepare warm saline with warm water, preferably boiled boiling water, distilled water or sterile water; rinse the nasal cavity with a squeeze bottle The water should come in from one nostril and then out from the other nostril, not from the mouth; use a whole bottle of saline at a time, and rinse each nostril with half a bottle of saline ... so this way, the nasal cavity can be washed.

 
This statement by netizens is basically reliable. But there is one thing: not everyone can do one nostril in and the other nostril out, which is often done by people who can swim. More people are "one nostril in, the same nostril out", or "nostril in, mouth out", it really doesn't matter.

Don't use iodized salt to make nasal wash

There are currently two types of nose washing, one is a physiological seawater nasal spray, and the other is nasal washing.

When it comes to nasal sprays, there are specialized nasal sprays on the market, mainly using professional nasal sprays, in conjunction with special nasal sprays. The advantage is that the pressure is moderate and the damage to the nasal mucosa is small.

In addition, if you make your own nasal wash, you must not use iodine-containing salt, as this will produce an undesirable irritation to the nasal mucosa. Of course, it is best to choose a special saline.

 
Our nose is seen from the outside, that is, an organ on the face, but in fact, its internal structure is also very delicate and complex. Since we want to talk about washing the nose, let's understand first, what is the structure of the nasal cavity?

 
The anterior nostril starts from the front of the nasal cavity and ends at the posterior nostril, and communicates with the nasopharynx. It is divided into two chambers by the nasal septum. Each nasal cavity includes two parts: nasal vestibule and intrinsic nasal cavity. However, many people's nasal septum is deviated, so the size and shape of the left and right nasal cavity may be asymmetric.

 
The structure in the nasal cavity can be described as a tortuous curve, not a straight road to the lungs. So when we breathe, the air has to go around.

 
In this process, some dirty things in the air will slowly deposit, without drilling deep into the lower respiratory tract; some dirty things will also hit the nasal mucosa, and then be stuck and wrapped by natural secretions on the mucosa Get up, and then excreted; in addition, the nose hair is also used as a sieve to filter, to block some foreign objects, and then expel them by sneezing.
