There are many factors that lead to frequent colds and coughs in children, which may be caused by the following factors: 1. The child may be born with a weak constitution and low immunity, and has no resistance to bacteria, viruses and other disease-causing microorganisms, so he or she is prone to colds and coughs. 2. 3. Inappropriate diet, as the child is often overindulged in greasy or cold food, resulting in internal dampness and heat, which can easily cause the child to catch a cold or cough. Therefore, parents should pay attention to the care of their children, such as diligent feeding of water, timely increase and decrease of clothing, more sunshine, and often go outdoors to exercise and enhance physical fitness. During the cold and flu season, try to take your child to places with a lot of people to avoid infection and coughs.
