This year, after the spring there is a period of significant cooling, many friends have a cold, all kinds of nose blowing sound, sneezing sound continuous. In fact, not only people with colds or allergic rhinitis will have snot, everyone is constantly producing snot every day. The truth about snot Under normal circumstances, the human nasal cavity secretes about 1,000mL of liquid per day, of which about 700mL evaporates to moisten the air in the nasal cavity, and the other 300mL is pooled on the surface of the mucous membrane to form a thin layer of “mucus carpet,” to protect the mucous membrane, preventing dryness, and also binds the air to be inhaled in the air of bacteria and dust, and other foreign matter. A lot of snot, was swallowed into the belly Nasal mucosa with cilia, these cilia will swing from front to back, snot will naturally be sent to the pharynx. Because the nasal cavity and the esophagus are connected, most of the snot that did not evaporate was unknowingly swallowed. Is not expected a lot of snot was actually swallowed, think about it is really a bit disgusting. The main components of snot, in addition to water, there are proteins, carbohydrates, salt and some shed cells. Among them, proteins include antibodies and lysozyme, which can kill bacteria and viruses. Of course, snot also contains stuck dust, pollen and microorganisms, but these things will be broken down by gastric acid in the stomach, and will not cause trouble to the body. Blowing your nose is a normal reaction Once you have a cold or a rhinitis, why do you feel snot? When you have a cold or allergy, the mucous membrane of the nose is irritated, edema occurs, secretion increases, and the normal channels for discharging nasal mucus are not enough, so you will feel your nose blocked and snotty, and you have to blow your nose to feel comfortable. Nose blowing is one of the body’s normal physiological response mechanism, just like sneezing, the harmful substances in the nasal mucus out of the body. The Dangers of Blowing Your Nose Most people blow their noses by pinching both nostrils with two fingers and forcefully blowing out the nose. Unbeknownst to them, this method of blowing the nose is wrong and dangerous. Because the nose and its surrounding organs are all connected: the nasal cavity and sinuses are connected; the nasal cavity is connected to the eyes through the nasolacrimal duct; the nasal cavity is also connected to the middle ear through the Eustachian tube. Therefore, if you blow your nose improperly, you may bring trouble to these “neighbors” around you, such as: pushing snot into the sinuses to cause sinusitis and headache; pushing snot into the tear ducts to cause conjunctival infections, nasolacrimal duct blockage, etc.; pushing snot into the Eustachian tubes to cause otitis media, which will not be cured for a long time and will damage your hearing. Therefore, it is very necessary to blow your nose correctly. How to blow your nose gracefully Posture: It is advisable to blow your nose with your upper body leaning forward. As the opening of the maxillary sinus is high, this posture is conducive to discharging the secretions accumulated in the maxillary sinus and avoiding sinusitis. Action: You should first press one side of the nostril with your finger and blow outward with a little force, so that the snot in the opposite nostril can be blown out. After blowing one side, blow the other side. Force: The standard level of force should be such that no buzzing sound can be heard in the ears, so do not use too much force. Appropriate medication: If your nose is not clear and it is not easy to blow out the snot, you can use ephedrine drops and wait until your nose is clear before blowing. However, ephedrine drops should not be used for more than a week. Pay attention to hygiene: Blow your nose on a piece of paper and dispose of it in the garbage. Remember to wash your hands after blowing your nose to avoid spreading diseases and polluting the environment. Don’t blow your nose excessively. Excessive nose blowing makes the whole nose red, ears buzzing and even painful, and may also damage the nasal mucosa and cause nosebleeds; acute and chronic sinusitis will be yellow, thick, and pus-filled, go to the hospital for treatment in a timely manner, and the doctor will prescribe some drops to be used in conjunction with blowing your nose again. Don’t pick your nose Sometimes the snot is dry, formed into dry scabs sticking in the nasal cavity, also called “boogers”, many people feel uncomfortable to develop the habit of picking their noses, in fact, this is a hundred harms and no good. Nasal mucus and nasal hairs adhere closely, nose picking is bound to damage the nasal hairs and the fragile mucosa of the nasal cavity, in the long run, it will cause the nasal nasal hairs to reduce the loss of secretion, the gradual loss of nasal cavity protection function, increasing the incidence of pharyngitis, bronchitis, pneumonia and other opportunities. Keeping moist can reduce the production of boogers, for example: use a humidifier when the air is dry and the indoor heating is sufficient; when you go out, you can put on a mask to keep the humidity of the nasal cavity, and can also prevent colds and other diseases. What should I do when I feel an itchy nose? Recommended saline rinse nasal cavity, not only can clean the nasal cavity, but also to maintain the normal physiological environment of the nasal cavity, to protect its function. Hospitals can buy saline and nasal rinser in the ENT department, after a simple study, can be done at home.
