Since the beginning of autumn, the cases of allergic rhinitis and asthma in children have been increasing. Autumn is the season of fruit ripening. A large amount of pollen and plant seeds will float in the air. Dust mites are easier to spread and breed in autumn. In addition, the air pressure in autumn and winter is usually low, which makes various allergens, such as pollen, mold, bacteria, dust and industrial irritants, easier to disperse in low places and invade the human body, causing allergy.
In addition, the fall of temperature in autumn can cause the vasoconstriction in the respiratory tract mucosa, reduce the local resistance, bacteria and viruses are easy to take advantage of the deficiency to directly induce asthma, and can destroy the closely connected epithelial cells to widen them, while other allergens from the outside can take advantage of the deficiency to induce asthma. Therefore, whenever the cold air comes, there will be a peak of asthma attack, so we should be careful to prevent asthma.
