If the weather is too cold, you will get rhinitis.

A little runny nose when it's cold, which means rhinitis. Snuff contains a large number of inflammatory substances, which are transported to the nasopharynx through nasal cilia to stimulate the throat, which can cause cough in severe cases. Nothing serious. Your illness is still very mild. Just recuperate and cure it directly.

Rhinitis is caused by long-term inflammation of nose, such as aggravation of cold, or physiological factors such as pregnancy or mechanical changes of nasal cavity structure, such as deviation of nasal septum. The inflamed part of the nose secretes a lot of purulent substances, which we call snot. Snuff contains a lot of germs and substances that can inflame tissues, so the accumulation of snot in the nasal cavity will worsen the inflammation in the nasal cavity, which is more likely to cause colds, forming a vicious circle of colds → rhinitis → more likely to catch a cold → rhinitis.

At the same time, these nasal mucus will be transported to the nasopharynx by nasal cilia, but it will stick to the nasopharynx because it is too viscous to slip into the stomach and be disposed of. These nasal mucus will constantly stimulate nasopharyngeal tissue, causing pharyngitis, and in severe cases, it will show cough symptoms. When the secretion comes out of the mouth, it will become what we call phlegm. So pharyngitis is usually accompanied by rhinitis.

The simplest and most effective way to solve this problem is to buy a yoga nasal wash pot, pour warm salt water into it, and let the water slowly soak and clean the tender tissue of the nasal cavity under the guidance of gravity to remove the snot on the surface of the tissue and the virus in the snot. Just wash it in the morning and evening, and be sure to wash your nose thoroughly when washing. After washing the nose, there is no irritant in the nasopharynx, and pharyngitis can disappear naturally. At the same time, the inflammation of various tissues will gradually disappear without the stimulation of nasal mucus. The previous vicious circle in the nasal cavity becomes a virtuous circle, and the diseased tissue cells will gradually be replaced by new healthy cells, and rhinitis will naturally get better, and people will not be easily infected. If you want to get the effect early when you start washing, you can increase the number of times. As long as it is cleaned every time, the more times it is washed, the faster it will work. This is physical therapy, which is very safe for the body and can be washed with confidence.

If drugs are used, they are basically in the blood, rarely reaching the surface of nasal mucosa to kill germs, and only have anti-inflammatory effects on tissues at most. When taking medicine, the inflammation can indeed disappear, but after the drug effect, the bacteria will continue to multiply and cause inflammation again, and the bacteria will gradually develop drug resistance, which is not good for the whole body.

Because washing the nose improves the resistance of the nose in an all-round way, it has a very obvious effect on preventing various non-infectious and infectious diseases such as colds and flu. In other words, cleaning the nasal cavity once after coming back from a crowded place can play a very good preventive role against all kinds of influenza.
