Pediatric colds are acute upper whistle infections in children. The main types of pediatric colds are pediatric wind-cold, pediatric wind-heat, and pediatric summer-heat colds. The causes of different types of pediatric colds are different. Among them, pediatric cold is generally caused by external wind and cold, winter and spring. Pediatric wind-heat colds are usually caused by external wind-heat and are more common in summer and fall. In contrast, pediatric heat and humidity colds are caused by external surface evils and are most common in the summer when it is hot and humid and young children crave cold or eat too much cold. Let’s take a look at the causes of pediatric colds. 1, the pathogenic infestation Infant upper whistle tract infections are mostly caused by viruses, and the nasal cavity of babies under 1 year old is very narrow and small with no nasal hair, plus the baby’s nasal mucosa is also very tender, which leads to insufficient secretion of their mucosal glands to resist viral infestation. 2, the baby’s immune function is not well developed The study has pointed out that the immunoglobulin IgM of babies under 1 year old is the least, and the ability to fight infection is also the worst. By the age of 3, it can reach the adult level, which is one of the reasons why pediatric colds slowly decrease by school-age children. 3, the indoor environment is poor When the room seems dark and humid, poor air circulation, or the indoor temperature seems too high or too low, will be very harmful to the baby’s respiratory tract, in this case it is very easy to induce pediatric colds. 4, hot and cold environment The hot and cold weather always catches mothers off guard. The temperature difference is so great that once mothers are in a hurry to add or remove clothes for their babies, it is extremely easy to induce a cold when the baby receives the stimulation of cold air. 5, and the baby’s diet related to a survey shows that if the baby grows too fast, the mother’s breast milk is not enough, and let the baby drink milk powder or because the baby is paranoid, anorexia and other reasons and eat not enough balanced and nutritious, it will easily cause different degrees of microelements lack, and thus lead to a great increase in the chances of colds. Therefore, parents must pay more attention to their children’s changes, do not be hot and cold, try to give children less puffed food, junk food, away from people who may spread pathogens. Give your child more calcium, increase immunity, and try to avoid the occurrence of colds!
