Baby loves to cough in autumn and winter. What causes children to suffer from respiratory diseases in autumn and winter?

In winter, the sunshine time is short, the temperature difference between day and night is large, the newborn care is unreasonable, and it is easy to catch a cold and cause respiratory infection. In winter, babies with active infection and weak resistance to various germs and viruses are vulnerable to germs and viruses, and diseases such as respiratory tract infection, dry cough, runny nose and high fever appear; The incidence of persistent respiratory tract in children is related to the lack of vitamin D and zinc in serum protein. Vitamin D plays a key role in improving the epithelial tissue of respiratory tract mucosa. When vitamin D is deficient, the cilia of squamous epithelial cells in respiratory tract recede, which leads to the dysfunction of cells in squamous metaplasia temples and glandular ducts, and the shed somatic cells block the lumen, and some defense functions are reduced, which can lead to the invasion of pathogenic bacteria and constantly produce a sense of purity.

Persistent respiratory infection in children is common in children aged six months to six years, especially in infants aged one to three years, which is related to the physiological and pathological characteristics of children. Traditional Chinese medicine believes that children's internal organs are delicate, their qi is not full, their functions are not perfect, their lungs are insufficient, and their ability to resist the outside world is poor. It is easy to understand wind evil and have respiratory tract feeling. The younger you are, the more obvious these physiological characteristics are. If you add that the child's innate resource endowment is not enough, the child is not properly fed or has not received effective medical care, there is less outdoor exercise, less direct sunlight, and the ability to resist wind and evil is also very poor.

The factors of high incidence of respiratory diseases in infants in winter are various and complicated. Winter is cold and dry, and the temperature difference between day and night is large. As a result, children's respiratory tract mucosal metabolic function is reduced, mucosal somatic cell IgA metabolism is reduced, ciliated squamous epithelial cell metabolic efficiency is weakened, ventilation function is endangered, respiratory system function is unbalanced, immunity is low, and pathogens and bacteria in the air easily enter the respiratory tract, thus causing children's respiratory tract infection. The harmful substances of environmental pollution have the same effect as the pathogenic bacteria of respiratory tract infection, which aggravates the occurrence of respiratory tract infection in children.

Children's respiratory tract infection is mostly caused by virus infection. Although many children are young, they don't go to crowded places or take part in outdoor sports, because of their weak resistance, adults at home are likely to carry sick virus infection, and adults have strong immunity and are not easy to get sick, but children are very prone to get sick with the same virus infection. In the season of frequent respiratory infections, special attention should be paid to maintaining indoor ventilation. Adults should change their coats and trousers after entering the room from outside, and wash their hands and wash their faces and mouthwash to prevent infection to children.
