Why is allergic rhinitis high in spring and autumn?

In spring, flowers are in full bloom; In autumn, everything harvests. In these two pleasant seasons, we will also encounter some minor problems, such as allergic rhinitis. So why is allergic rhinitis high in spring and autumn?

All this is closely related to meteorological elements!

First of all, the pollen concentration, the chief culprit of allergic rhinitis, is the highest in spring and autumn. For Beijing, trees (Cupressaceae, Pinaceae) bloom in spring, and the pollen concentration reaches a peak. In autumn, herbaceous plants (Humulus, Ambragaceae) bloom and the pollen concentration reaches the peak again. Then, I think some friends will ask: there are many smallpox in summer, why is the pollen concentration not high? Because plants mainly rely on wind to spread pollen in spring and autumn, the pollen grains are small and allergic, while plants that bloom in summer mainly rely on insects to spread pollen, and the pollen grains are large and allergic.

Secondly, when there is little rain in spring and autumn and the daily minimum relative humidity is below 15%, "dry days" often occur. This will further increase the concentration of pollen in the air: during the pollination period, if it rains continuously, it will not only clean the pollen scattered in the air, but also be detrimental to the spread of pollen. However, on sunny days like partly cloudy, relatively high temperature and dry air, the wind is relatively strong, which is conducive to the spread of pollen in the air.

Finally, spring and autumn are the seasons of climate change. The temperature is changeable, cold and hot, and the temperature difference between day and night is large, which leads to the decline of human resistance. At the same time, it is dry in spring and autumn, and the nasal mucosa is easily damaged. The interaction between them makes people more susceptible to allergic rhinitis.

So, how to prevent allergic rhinitis? Allergy channels are mainly divided into contact, inhalation, food and injection, and the most important means of prevention and treatment is to avoid allergens. Therefore, we must first identify allergens, and bring glasses and a high-density mask when going out; Stay outdoors less, especially where there are many allergens. Pay attention to diet at ordinary times and reduce high-protein and high-calorie diet; Adhere to exercise and enhance immunity.
