Kindergarten itself is a place where children gather, with a high population density. When winter comes, there is less time to open the window for ventilation, the indoor air is dirty and the infection rate is high. Winter heating is easy to cause dry air, especially air conditioning heating, with low humidity. Dry air is most likely to cause stress reaction and cough in the pipeline. If it is a central air conditioner, if the pipeline is not cleaned for several years, bacteria are easy to spread and easily induce bronchial inflammation in the pipeline. These will cause upper respiratory tract infection, causing colds, fever, cough and so on.

Countermeasures: ventilate and keep the air relatively clean. If the humidity is too low, a humidifier can be used to improve the air humidity.

The second reason is insufficient outdoor activities and insufficient water supply.

With the cold weather, many kindergartens are afraid of freezing their children and reduce outdoor activities. Children do not like activities, full meals are not easy to digest, gastrointestinal peristalsis is slow, food accumulates heat, resistance drops, and it is easy to catch a cold. It doesn't matter if the weather is cold. When the weather is sunny, let the children fully move outdoors and sweat. Only by persisting in this way can the child's immunity be improved. In addition, children tend to forget to drink water after going to kindergarten. Water can extinguish fire, drink plenty of water, eliminate heat evil in the body, prevent colds and improve immunity.

Countermeasures: Try to arrange appropriate outdoor activities and give children water regularly.

Reason 3: The most important one is a moderate diet.

Many kindergartens arrange two meals for their children. When eating, every child's meal is almost the same, roughly even. In addition, the teacher also asked to eat clean food and not to waste food. Sometimes they are still playing games to see who eats fast and clean. They can also reward a small red flower. Many children are scrambling to eat something they can't eat early and eat it cleanly. But don't forget. Every child's constitution is different. He has a good spleen and stomach. He eats much and fast, but his spleen and stomach function is poor. He can't eat so fast, so he must eat so much. As a result, there was only one person, eating too much, eating too much, phlegm fever, cold and fever, cough, bad smell in the mouth, dry stool and vomiting. People in China may be hungry, especially the elderly, and they love to eat many good things from their children. Many parents have very high dietary requirements for kindergartens. If it is light, many parents give up. Therefore, kindergartens also pay special attention to eating, and there are recipes every week. Protein, fat, sugar and vitamins are abundant. There is no difference in thickness, but each child's appetite is different, and so is his appetite. It varies from person to person, and the amount of food is irregular, which is definitely different. Parents should also understand that they should not misunderstand the miserliness of kindergartens and reduce their children's food expenses.
