Looking at the yellow and green on the toilet paper in your hand, a small sense of achievement arises spontaneously, and your breathing suddenly becomes easier... I believe most friends have a cold and stuffy nose, which is how to solve the runny nose. Indeed, nasal congestion is very uncomfortable. Many people will ignore it, pinch one side of the nostril with their fingers and blow their nose out very hard. Doing so may lead to some problems, such as blowing your nose hard, resulting in a sudden increase in nasal pressure, making infectious nose enter the sinuses, causing sinusitis, or squeezing infectious nasal secretions into the eustachian tube, causing otitis media, or squeezing into the nasolacrimal tube, causing lacrimitis, or nasolacrimal duct blockage, etc. So, don't be too violent towards our delicate little nose. Some friends may think that since I can't blow my nose, can I pull my head office? In addition to being unsightly, this behavior may bring pathogenic microorganisms such as bacteria and viruses into the nasal tract and cause nasal infection. At the same time, the nasal mucosa is subjected to mechanical stimulation such as picking the nose, which is more likely to cause intranasal inflammation. If you accidentally cut the blood vessels in the nasal cavity, it may cause epistaxis, and you may dig out the nasal hair, reducing the filtering effect of the nasal hair on harmful substances and causing nasal infection. In addition, because the nose is in the "dangerous triangle" in medicine, if the inflammation is not well controlled, it may invade the intracranial, causing meningitis and encephalitis, which is life-threatening. If you don't blow your nose or pick your nose, it just doesn't breathe in and out smoothly. What should you do? Here's another trick, that is to wash your nose. First of all, it's best to use professional nose washing tools, not necessarily expensive electric models. Secondly, 0.9% normal saline is recommended for nasal washing. The iodized salt we usually eat is not recommended for nasal washing, which has potential health hazards. There is also expensive natural sea salt or hot spring salt. Medical research reports point out that the effect of washing the nasal cavity is not better than normal saline, and the feeling of use is not more comfortable than normal saline. The preparation method of normal saline is to add 2.25g nasal wash salt to 250ml warm boiled water, and the warm saline with a temperature of about 37 ℃ is more suitable. There is also 0.9% normal saline directly prepared on the market. According to personal needs, it can be cleaned 1 ~ 2 times a day, but not the more the better. Cleaning the nasal cavity is particularly important if nasal patients exposed to a lot of dust in the working environment, such as coal miners, carpenters, cement workers, chefs, tailors, barbers, etc. In addition to cleaning the nasal cavity, when you have a cold and stuffy nose, you can also consider hot compress your nose, such as covering your nose with a hot towel for a while to help nasal circulation and restore ventilation.
