Among many nose washing methods, physiological saline is the first choice. The so-called physiological saline nasal washing is to send physiological saline into the nasal cavity in various States through a certain pressure. First of all, the appropriate concentration of salt water has the effect of dehydration, which helps to reduce nasal mucosal swelling; Salt water has bacteriostatic effect; Medical proof shows that physiological saline can promote the mucociliary movement on nasal mucosa and accelerate the discharge of nasal mucus. Secondly, the nasal cavity and sinuses can be completely cleaned by adjusting the pressure. It also helps to adjust the humidity of the nasal cavity so that the nasal cavity will not be too dry or too wet. Finally, the massage effect is achieved through the physical movement of the water flow, which makes the nasal cavity swell and gradually restore its function. Because only normal saline is used instead of medicine, nasal washing with normal saline is a real green health therapy.
In the choice of salt water, the research shows that the iodine-free salt with the concentration of 0.9% is the most suitable for warm water. It is the same as the normal saline that children usually use in the hospital. Another thing to pay attention to when cleaning the nasal cavity is stress. It's not that the greater the pressure, the better, but that you feel comfortable. Because the nasal mucosa itself is a very sensitive tissue, if it is destroyed, it will not only have no therapeutic effect, but also aggravate the condition. If the water can be discharged from the throat smoothly in the process of nose washing, it can also sterilize the pharynx while cleaning the nasal cavity, which also has a certain curative effect on pharyngitis. Refer to China Rhinitis Green Treatment Network.
Saline treatment is a very old method, which is actually a health care method used to strengthen the body in Chinese medicine and yoga-nose washing. Later, people found that this method had a good effect on rhinitis, so it was used to treat rhinitis. In fact, it is true and effective, and its principle is actually easy to understand:
1, salt water itself can diminish inflammation and kill bacteria. Saline is sodium chloride, and sodium can diminish inflammation. Rhinitis, as its name implies, is an inflammatory problem. Anti-inflammation is necessary, and it will have certain effect.
2, the role of cleaning. First, cleaning can wash away some pathogenic bacteria in the nasal cavity and eliminate the root cause of inflammation; The second is to remove the secretions brought by inflammation, such as inflammatory nasal mucus, scab, purulent secretions, etc., so that the symptoms of rhinitis will be alleviated or disappeared.
I will post another post to explain the detailed principle of saline nose washing. )
Today, I will only teach you how to use it:
Remember these key words: 0.9%, iodine-free salt, salt water higher than 0.9% can be used properly for nasal congestion, do not use high-concentration salt water as trunk, and use appropriate tools.
I suggest you buy normal saline for injection, because it is clean and the concentration is appropriate. 0.9% physiological saline is most suitable for nasal cilia swing (normal nasal cilia swing is an important symbol of normal nasal function). Excessive concentration will do harm to nasal cilia swing. So generally speaking, 0.9% is enough.
Second, if you make your own salt water, the preparation method is to add 4.5 grams of salt to 500 ml of water, which is 0.9% salt water.
Third, be careful not to use salt at home. The salt used now is generally iodized salt, which is not suitable for nasal cavity. Iodine can be eaten in small amounts, but it cannot be used in the nasal cavity. Iodine absorption is limited after oral administration, but absorbed in nasal cavity. In medicine, the effect of nasal administration is equivalent to intramuscular injection, because the capillaries in nasal cavity are very rich and easy to cause harm to human body.
High concentration saline takes effect quickly, but it has some side effects. Therefore, the use time should not exceed 7 days.
Generally, patients with nasal congestion symptoms can consider using high-concentration physiological saline appropriately, because high-concentration physiological saline can reduce swelling faster and solve nasal congestion symptoms faster.
However, people without nasal congestion or dry nose should not use high-concentration physiological saline, which will not only have no effect but may aggravate it.
3, it is best to heat the water before use, so that the effect will be better, not irritating the nasal cavity, and more comfortable to use. Just control the temperature of hot water to be about the same as the human body temperature, just feel it, don't be very accurate, and be careful not to burn it. This is very important especially for allergic rhinitis. Many allergic rhinitis are very sensitive to cold and temperature changes, and if cold water is used, the symptoms will be aggravated.
4. It is best to use special nose washing tools. At present, there are various styles of such tools on the market in China. Generally, the more expensive tools will have a better effect after use, and the cheaper ones will also have an effect, but they may not be as good as those more advanced tools. The main difference between these tools is that some can reach more parts of the nasal cavity, while others can't, so the final treatment effect is different.
