Some people say that newborn babies are prone to pneumonia in winter. Why?

Newborn babies are prone to pneumonia in winter, which is caused by the physiological structure of newborns and improper parental care.

Physiological structure of newborn

When a baby is born, its physiological structure and immune system are extremely fragile. The baby's trachea and bronchial cavity are relatively narrow, and tracheal mucus secretion is less. Once bacteria and viruses invade, the baby has almost no self-cleaning ability. Neonatal lung elastic tissue is poorly developed, and the number of alveoli is small, which is easy to be blocked by mucus. The baby's chest is cylindrical and the respiratory muscles are stunted. In addition, the baby's defense system is not fully developed, and it is easy to be infected by viruses, thus inducing pneumonia.

Improper parental care

The unique physiological structure of newborns makes them vulnerable to virus infection, and newborns are more prone to pneumonia in winter, not because of the low temperature. However, because in the cold temperature, novice parents are always afraid that their baby will catch cold and add too many clothes to their baby, and the baby's ability to regulate body temperature is very poor, which often leads to pneumonia. There are also some parents who turn on the air conditioner too high in winter, which is easy to cause the baby's respiratory mucosa infection, thus causing pneumonia. In addition, the temperature difference between indoor and outdoor is large in winter, so the baby stays outdoors for a long time. When it comes back indoors, it is easy to catch a cold and have a fever. In severe cases, pneumonia will form.

How to prevent neonatal pneumonia

Maintain proper indoor temperature and humidity. Every morning from 10 to 12, open the window for ventilation and keep the air circulating. If your family has a cold, you should avoid contact with children and wear a mask if necessary. Neonatal pneumonia is usually infected by droplets. Parents should take their children to crowded places as little as possible, always pay attention to the baby's hygiene and wash their hands and change clothes as soon as they get home. If the baby has symptoms of a cold and cough, it must be treated in time to avoid serious pneumonia caused by a cold.
