Snot is a problem that every baby can’t avoid. When parents see their baby’s nose coming out, they want to stop it immediately and come to the hospital to ask the doctor to prescribe medicine (often persuasion is ineffective), but is it right to do so? What should parents do? I. Where does snot come from and where does it go? The nasal mucosa secretes nasal snot, which is secreted 24 hours a day, about 1000ml-1500ml a day, and you may ask, “Is it that much? How come I don’t feel it? Haha, that’s because most of the snot is drunk by you unconsciously. Except for a large part of the swallowed, a very small part of the remaining snot is evaporated, and a part of it dries up and forms boogers. Second, snot is so disgusting, why do we need to have snot? 1.Nasal snot can moisten the respiratory tract and moisten the inhaled air, which is beneficial to the respiratory function of the lungs. 2.Nasal snot is the protective layer of the whole nasal mucosa, preventing the mucosa from being damaged by drying and cracking. 3.Nasal snot can stick to the pathogenic microorganisms and dust that enter the nasal cavity and avoid them from entering the lungs. Therefore, nasal snot is the gatekeeper of our respiratory tract, we can’t live without it, don’t be disgusted. Third, what do various colors of nasal snot represent? 1.Clear nasal mucus that can’t be stopped: This kind of nasal mucus is clear water-like, thin and transparent, flowing out from the nasal cavity continuously. This kind of nasal discharge is most common in the early stage of upper respiratory tract infection (commonly known as “cold”), which is caused by viruses or bacteria. This is because the mucous membrane of the nasal cavity is congested and swollen, and the secretion of the glands increases, so the purpose is to flush out the pathogens from the nasal cavity as soon as possible, so at this time, we should not think about stopping the nasal discharge as soon as possible, but try to let it out. Generally speaking, in case of viral cold, the nasal discharge will become thick for several days, but the body temperature will improve, while in case of bacterial one, the body temperature will not improve after the nasal discharge becomes thick after several days. When there is a lot of runny nose, it also causes coughing and other manifestations when it flows downward through the pharynx. Also, this kind of nasal mucus can be present in case of allergic rhinitis. For example, if a child is allergic to pollen, when pollen is flying in spring, the baby may have a runny nose and a cough that won’t stop, which is allergic rhinitis. The body wants to flush away the allergen – pollen from the nasal area as soon as possible, so a lot of clear snot will flow out, huh, salty taste oh. 2, thick thick/white nasal snot If the nasal snot becomes thicker, or becomes white, it suggests that the inflammation at the nasal mucosa has increased. Viruses and bacteria can cause inflammation, which is manifested by swelling of nasal mucosa, congestion and nasal congestion, and the above problems will lead to slow down the flow of mucus, and the nasal mucus will become sticky and cloudy. Meanwhile, when there is inflammation at the nasal cavity, white blood cells will gather at the place and secrete into the nasal mucus, and the white blood cells show white or yellow in the nasal mucus, which causes the nasal mucus to become white in the early stage. Therefore, thick nasal discharge and white nasal discharge are mostly manifested after 2-3 days of viral or bacterial cold. 3.Purulent yellow or green nasal mucus In the case of bacterial or viral infection, white blood cells will gather in large numbers at the site of infection, which may have 100 times more than usual. After the battle between white blood cells and pathogen, the pathogen debris and white blood cells are discharged into the nasal mucus, showing yellow or green color. The white blood cells may cause the nasal mucus to show yellow color, while the enzymes in the white blood cells react (kill the pathogen) to show green color. Generally speaking, if yellow-green nasal mucus lasts for about 10 days without any discomfort such as fever or headache, it suggests a viral cold, so just continue to wait quietly. However, if there is yellow-green nasal mucus accompanied by fever that does not go away, nausea and headache, it suggests a possible bacterial infection leading to sinusitis and other conditions. Therefore, the appearance of yellow and green nasal discharge does not mean that the condition is more serious than white nasal discharge, and we should not think that yellow or green nasal discharge is a bacterial infection and take antibiotics immediately. 4, pink or red nasal mucus suggests bleeding in the nasal cavity, which may be caused by dryness, trauma, inflammation and other causes of nasal mucosa damage. Winter is here, the sky is dry, so, children have a bloody or pink nose, the humidifier is recommended to use up oh, the appropriate air humidity of 50%-60%. 5, brown nasal snot Brown nasal snot mostly suggests that there are dirty things mixed in the nasal snot, such as dust, dust, etc. A few cases are some old bleeding. If your baby has a brown nose, clean the nostrils first, use sea salt water to spray and wash the nose. 6, black nasal snot The baby’s black nasal snot may be caused by inhaling too much dust, such as soot. It may also be caused by the baby being forced to inhale second-hand smoke for a long time, and some gases in the smoke or lead may be the cause of black nose. If none of the above and the baby has immune system disorders, then consider whether there is a fungal infection and go to the hospital immediately for examination. Fourth, the baby has a runny nose, how do parents do? 1.Let’s first distinguish whether it is snot. Some babies have drops of water hanging in their nostrils when it is cold, parents think it is a cold, immediately give on the cold punch to drink, this is not desirable, because these drops are formed by the liquefaction of water vapor in the nasal cavity, do not think it is clear nasal snot ah. 2, according to the appearance of the nose and other symptoms, treated separately: (1) If the baby is running a clear nose, sometimes there may be some fever, but the spirit is very good, eat and drink, just the onset of the disease course is not long, you can observe at home, ensure rest, ensure drinking water. Even if you go to the doctor, do not ask the doctor to prescribe medicine to stop the runny nose. (2) If the nasal discharge turns yellow or green, but the child does not have a fever, it is more likely to be a viral cold, which will generally heal on its own in about 10 days, and the focus is not to stop the nasal discharge, but to observe whether there are complications. (3) But if the nasal discharge turns yellow and green, the child’s fever becomes heavier, suggesting the possibility of bacterial infection and the need to go to the hospital for treatment. (4) If the baby is exposed to pollen or has a runny nose and cough when he/she goes to a certain room, it suggests allergy, so first leave the environment and then go to the hospital for examination. (5) If your baby only has pink snot once, after cleaning up your baby, turn up the humidity in the room (50-60%) so as to moisten the mucous membrane of the nasal cavity, and check whether your baby often picks his nose. It is also necessary to check whether the baby often picks his nose. It is also necessary to pay attention to medical examination if there is often blood in the nose. (6) If your baby has brown snot, don’t let your baby go out to inhale haze on a hazy day, just play in a clean room. (7) If your baby has black snot, then make sure that your child’s living environment is clean, and make sure that you don’t let your child inhale second-hand or third-hand smoke, and that your child’s father is determined not to smoke indoors, whether your child is present or not, because the soot deposited on the sofa and bed will only subside for a long time, which has a great impact on your child. In addition, if there are no environmental problems mentioned above and the baby has immune dysfunctional diseases, he/she needs to go to the hospital immediately. In conclusion, the focus is not on stopping the runny nose but on examining the cause of the illness and treating the cause and observing the condition. Moreover, stopping the runny nose with medicine is not the root cause of the problem.
