? After I went to college, I was lucky enough to be exposed to Tai Ji Chuan, American Boxing, Taekwondo, Judo, Swimming and other fitness methods (in chronological order) because of club activities and physical education class (I chose eight seniors from physical education class). The number of colds is decreasing every year. At first, I insisted on punching and stretching in the outdoor stands in winter, but my resistance to colds did improve. In short, I put the foundation into practice. But the real order of magnitude improvement is after contact swimming. My undergraduate roommate loves swimming. He was puzzled by my frequent colds. He once said to me, "Let's swim if you have a cold." Because of this sentence, I, a 20-year-old landlubber, decided to take two swimming lessons in a row when I was the busiest in my junior and senior years. Sure enough, the number of colds has dropped by an order of magnitude, and only a few colds will be caught in winter.
? My nose is not good for no reason, and it is good for no reason. Although there are so many reasons in the adult world, curiosity still drives me to think about what determines the number of colds a person has every year. Because it's so strange, some people look strong, their arms are thicker than my calves, but they often have colds and fever like me. His girlfriend said he was weak and honest.
? As we all know, a cold can't be cured. Taking medicine only relieves symptoms. Symptoms are a good thing, just like a bleeding soldier will destroy the surrounding houses in battle. Symptoms are wounds caused by a large number of immune cells struggling with cold viruses. Everyone's upper respiratory tract, especially the throat, has a large number of cold viruses, which are copied all the time. The reason why there are no symptoms is that immune cells can kill the virus at any time and keep it in balance. The equilibrium state will be broken in the following three situations:
? As we all know, the air in northern China is very poor. Particulate matter in the air itself is not terrible. If you simply suck a coal particle and eat a sand, it's nothing, which is much less harmful than smoking. What is terrible is the germs or allergens carried on it.
? By the way, some girls actually don't like listening to boys and pointing out the maze. Talking about the international situation and smog pollution is not very pleasing. There is a simple reason. Of course, the macro trend depends on it, but what we can change is the micro. Controlling pollution sources or controlling diffusion process is a worldwide problem, even in developed countries. Therefore, we can only improve our preventive ability from the receptor.
? I first came into contact with the idea of nose washing when I read it in a life magazine. It is said that there is a trick to wash your face in winter, holding water in your hand to moisten your nostrils, which has the effect of preventing colds. At the same time, several other tips are listed, such as egg cleaning stains and so on. I have a black question mark face inside. What? Inexplicably, it is the same as eating garlic raw to prevent cancer. So I didn't care much at the time.
? What really made me notice this life trick may have its reasonable ingredients, that is, I once went to eat Hunan cuisine with my friends. I can't eat spicy food very much. The spicy food of Hunan cuisine is really spicy, which is different from the spicy food of Sichuan cuisine. I'm so hungry that I can't leave the bathroom for half an hour. But when I recovered, I found that my nose was more transparent than before. Immediately think of the role of wetting the nostrils when washing your face, that is, cleaning the dirty things in the nasal cavity. The difference is that eating spicy runny nose produces liquid from the inside, thus removing dirty things, while flushing nostrils washes dirty things from the outside.
? Reminiscent of the experience of swimming to prevent colds, I finally thought of washing my nose with a pool containing hypochlorous acid disinfectant for one hour when swimming. Of course, I can wash off the dirt in my nose.
? Eating spicy food to wash your nose is too masochistic, and washing your nostrils with tap water is too inefficient to wash the depths of your nostrils. Later, I thought that the difference between humans and orangutans is that people can use tools, so I searched for a nose washer, and sure enough, a treasure had this thing. Disclaimer: This article is not a soft advertisement, and it is not intended to advertise the nose washer.
? Nose washer usually uses pressure (such as air bag nose washer) to send physiological saline into the nostrils, flow through the nasal vestibule (the part exposed outside the head), sinuses and nasal passages, bypass the nasopharynx, enter from one nostril and discharge from the other nostril. Through the above path, the accumulated dirt in the nasal cavity is discharged by the sterilization of physiological saline and the impact of water flow, so that the normal physiological environment of the nasal cavity can be restored and the living space of immune cells will not be squeezed.
? Nasal irrigation is one of the long-standing health preserving methods in Indian yoga and China Taoism. The early method was to scoop up clean water with both hands, forcibly suck the water into the nostrils, and then spit it out from the mouth, thus removing the snot and dirt from the nasal cavity. It sounds simple, but in fact, if you are not careful, you will be choked, similar to the experience of swimming being choked by water. In China, where air pollution is serious, nose washing is rarely used, and the flowers inside the wall smell fragrant outside. On the contrary, westerners inherited this ancient method and further invented the nose washer. In the past hundred years, the use of nasal lavage in the west has never stopped.
? Nasal cavity is an important channel for human body to communicate with the outside world except oral cavity. In fact, it is used much more frequently than the oral cavity, because people need to breathe all the time. Impurities and harmful substances in the air are blocked in the nasal cavity by the filtering function of the nasal cavity when inhaled into the human body, so that they cannot enter the lungs. However, if these impurities and harmful substances are not cleaned up in time and stay in the nasal cavity for a long time, they may produce more bacteria and cause nasal lesions. Like a clean land, the garbage dump has been around for a long time, and flies and bugs are flying everywhere.
? It was really painful to wash my nose at first, which made me regain my fear of being dominated by choking water when I first learned to swim. Add a certain amount of mineral water and medical salt into the nose washer, shake it several times and mix it evenly to make normal saline, insert it into the nostril, and press the nose washer with your hands. Because the head posture is wrong, the water temperature is too cold, and I feel a torrent rushing straight to my forehead, scalp and upper nose.
? Mistakes in nose washing:
? As for the frequency of nose washing, it should be once in the morning and once in the evening when you have a cold or rhinitis. In northern cities, especially in heavy industrial areas such as Beijing, Tianjin and Jin Lu, it is usually washed once a day. The southern clean area can be washed once every two or three days.
? Nose washing is as anti-human as fitness and weight loss. It's really not easy to stick to it. For my chronic rhinitis or pharyngitis, I have been washing my nose every day for more than two years. During this period, I only had two respiratory infections and runny nose, all because of my roommate's infection. Just like push-ups and other projects, if you persist for more than one month, you will slowly see the effect.
? In addition, I need to emphasize that the value of insisting on nose washing far exceeds the cost of time and money. In addition to avoiding the decline in work efficiency caused by colds, there are other unexpected benefits. For example, we all know that when Shandong people speak Mandarin, because of the influence of Jiaoliao dialect pronunciation, the airflow basically comes out of the nose, so the nasal sound of Shandong people is particularly heavy and has a strong local flavor. If you want to speak Mandarin well, you must exert your strength in the abdominal cavity, push your breath up, and then make a * * * sound through the chest cavity. At last, the airflow comes out from the back of the throat cavity, with full, round and powerful voice, strong penetration and high sound pressure. This pronunciation is a necessary skill for bel canto, broadcasting and American English. Without it, the pronunciation standard is impossible. After insisting on nose washing, my Mandarin pronunciation has made a qualitative leap. Outsiders can't hear it, even I speak English very well!
Great things take time. Enjoy your breath and good luck.
