Spring is the season of high incidence of respiratory allergies such as allergic rhinitis. In order to protect the first line of defense of the respiratory system, many people will clean their noses with a nose washer to clean the nasal cavity and relieve the nasal mucosa. Generally, a certain pressure (or suction, gravity or mechanical pressure) is used to send the saline solution into the nostrils, and the saline solution flows around the nasal vestibule, sinuses, nostrils and nasopharynx, or flows out from the other side. It is discharged from nostril or oral cavity, and pathogenic bacteria and dirt accumulated in nasal cavity are discharged through the impact of physiological saline flow, thus achieving the purpose of protecting nasal cavity. When washing your nose, you should slow down your breathing. First, gently absorb water through your nose, pause for a moment, and then exhale.

The nasal cavity cleaning methods of rhinitis mainly include hand washing and nasal spray washing. First-time users need to operate under the guidance of professional medical staff. First, wash the nasal cavity with clear water as a backup, heat the normal saline to a temperature close to the patient's body temperature, and then pour it into the nasal cavity for a backup. My mouth doesn't talk or cough. After preparation, insert 15ml physiological saline into the nasal cavity from one front nostril to the nozzle end of the nasal cavity irrigator at a uniform speed, rinse the nasal vestibule, paranasal sinuses and nasal cavity, then leave it in the nasopharynx for1-2min, completely moisturize, and the scab skin and secretion in the moist nasal cavity will flow into the back nostril and flow out from the other nasal cavity, and then take out the scab skin and secretion in the nasal cavity.

You need to lie on your back and tilt your head slightly. Put the sprayer into physiological saline, aim the sprayer nozzle at the nasal cavity, gently press it, spray it on each nostril several times, and then pour out the washing liquid.

Nasal lotion is usually used with nasal salt. There are many kinds of nasal washing salts on the market. Some nasal washing salts will also add baking soda to enhance the nasal washing effect. When buying nasal salt, you need to pay attention to the iodine content in the salt and try not to use iodized salt. Use normal saline or hypertonic saline with a concentration not exceeding 2% when washing nose. Nose washes purchased online generally have dilution instructions and can be mixed according to the instructions; If there is edema in the nasal cavity, hypertonic saline can be used, but the service life cannot exceed 1 week. The sensitivity of the nose varies from season to season. When washing your nose in summer, the water temperature is slightly lower. In winter, the water temperature can be higher.

Nose washing can clean the pollutants in the nasal cavity, but it can only be used to relieve symptoms such as nasal congestion and runny nose caused by rhinitis, and it can not play a fundamental therapeutic role.

Patients with otitis media should avoid nasal lavage. Because the ear, nose and throat are connected, nasal lavage in patients with otitis media will lead to saline entering the ear and aggravate otitis media. Children under 6 years old should also try to avoid using it. The nose washing technique is skilled, but the child's control ability is poor and the level of cooperation is low. In order to avoid risks, it is best not to wash your nose as much as possible.
