Normal saline, that is, 0.9% sodium chloride aqueous solution, should not be used with high concentration of normal saline, which will destroy the nasal environment. Because if some water is not treated, it will contain some bacteria, which will aggravate the infection of nasal mucosa and lead to the aggravation of rhinitis. ? Normal saline is really non-toxic and drug-free, and will not cause harm to human body. Use this physical method to remove impurities, bacteria, etc. It will not make the human body dependent in the nasal cavity. It is a good method to treat rhinitis and has been recognized by many professional doctors. What should I pay attention to when washing my nose with salt water?
1, pay attention to the solubility of physiological saline. 0.9% physiological saline is most suitable for nasal cilia swing, but too high concentration will do harm to nasal cilia swing. If you prepare your own physiological saline, the method is to add 2.25 grams of nasal washing salt to 250 ml of water, which is 0.9% physiological saline. Be careful not to use edible salt. Washing the nose with edible salt for a long time is easy to cause iodine poisoning, and it is best to use physiological saline.
2. Before washing the nose, control the water temperature to be close to the human body temperature (37C), which has no irritation to the nasal cavity and is the most comfortable to use.
3, nasal congestion can be properly washed with 2.7% high-concentration physiological saline, because high-concentration physiological saline has a faster swelling effect and can quickly solve the symptoms of nasal congestion. After nasal ventilation was restored, 0.9% saline was used again. If both nasal cavities are not ventilated, please use decongestant to help restore ventilation before nasal irrigation. Try to reduce the frequency of washing with high concentration physiological saline to avoid damaging nasal mucosa.
4. Choose a nose washer that suits you. Different nose washers have different cleaning effects. The main difference between nasal lavage devices is that some can wash all parts of the nasal cavity, while others can't. Nose washer is different from other products. It is designed with a built-in nasal vestibule. The patented design of the built-in nozzle can avoid the obstruction of the nasal threshold to the water flow and realize the flushing of the frontal sinus and the upper nasal meatus. The upper nasal passage is easy to retain pathogens, allergens and other substances, which the traditional external nozzle can not do.
? 5, flushing is not suffocating, it is also a misunderstanding not to suffocate when flushing. If you suffocate when flushing your nose again, then salt water will flow from the nasal cavity. If you don't suffocate, it will enter the middle ear of the human body through the eustachian tube, which will also cause middle ear diseases. So hold your breath when you rinse your mouth again, so as not to damage other organs of your body.
