Every year, starting from February 4, spring, everything revives. The river, which has been frozen all winter, flows. When the wind blows, the grass, tree buds, spring flowers, and green leaves all rush to the forefront. Everything around us is springing up more and more every day. The green spring makes us feel the life, hope and vitality. Spring is always so beautiful. However, under the brightness of spring, there are also dangerous disease-causing factors. As everything grows in spring and all flowers bloom, pollen and willow will easily drift to every place around us under the spring breeze, even into our home bedrooms, into our nasal cavity and throat, adhering to our respiratory tract, causing allergic rhinitis, allergic cough, allergic asthma and a series of allergic diseases, manifesting as runny nose, tearing, sneezing, coughing, even asthma, breath-holding, and difficulty in breathing. Breathing difficulties, bringing us discomfort and even difficult “spring time”. Allergic diseases in spring, once suffered, are not only painful, but also very likely to recur every spring. Allergic cough asthma, for example, can also cause pathological damage to the airways and alveoli over a long period of time. Year after year, it may induce bronchiectasis, emphysema and other diseases, seriously affecting our quality of life. Therefore, it is important to prevent allergic diseases of the respiratory system in spring. We know that cough is not only a respiratory pathological response, but very often a defensive one. The trachea, bronchi, alveoli, have phlegm lodged in the respiratory tract and we excrete it by coughing. We also cough when we choke on wind, choke on water, or have a foreign body in our throat, and we excrete these foreign bodies that enter the throat and trachea by coughing, which is a physiological cough. Allergic cough in spring is often caused by pollen and willow entering the trachea through the nasopharynx. Therefore, by keeping the first gate and not allowing foreign substances such as pollen and willow to stick to the nasopharyngeal membrane and reducing the irritation response of the nasal mucosa, the probability of allergic cough will be reduced. However, it is not easy to block the pervasive pollen and willow flakes that are carried by the spring breeze! In addition to wearing a mask when you go out, Director You would like to introduce a small recipe to help you keep spring irritants such as pollen and willow wool out of your nasal cavity in a simple and effective way. The specific operation is as follows: Step 1: Clean up dry nasal snot. Every day before going out, use a clean cotton swab dipped in water (not too much water) to gently turn the nasal cavity three times to moisten the dry snot on the nasal mucosa. After a minute, use a moist cotton swab (don’t drip water on the swab) to clean up all the dried snot. Step 2: Dry the nasal cavity. Use a semi-dry cotton swab to absorb all the water from the nasal cavity. Step 3: Oil the nasal cavity. Use a clean cotton swab dipped in good quality olive oil to gently apply it on the nasal mucosa, applying it as well as possible. The more recent the production date of olive oil, the better, never use the expired, long or smelly oil, because after the oil deteriorates, the smell is unpleasant and it is very painful to smudge yourself in the nasal cavity. Part 4: Clean nasal door. Finally, use a clean cotton swab to wipe the nostril doorway oil clean, lest with two bright nostrils to people with the feeling of snot. Nose care well, and then put on a mask, we can rest assured that we can go on the road. This method can be used by both men and women, young and old. As it adds a very effective protective layer to the nasal mucosa, pollen and willow can’t stay or stand still and are less likely to stimulate our respiratory tract and trigger sneezing and continuous coughing. This way, we have more opportunities to go out and experience the spring scenery and the wonderful nature.
