Dress reasonably
Touch the child's hand often. If it's cold, add a dress for the child. Children generally have a large amount of activities, need to wear less clothes and cover less than adults. When you go out, you can give your child a bigger coat to keep out the wind; When you enter a heated room, you should change into a small vest that is easy to put on, take off and move. Pay attention to bring an extra dress that is easy to put on and take off during the activity, and replenish it in time after the activity.
Adapt to the cold environment
Man is a warm-blooded animal, and he has a perfect thermoregulation system in his body. Cold air entering the respiratory tract can stimulate various systems of the whole body to make corresponding regulatory responses. However, because children's adjustment ability is still immature, they are more likely to catch a cold and get sick than adults, but this ability can be gradually improved by adapting to the cold environment in daily life.
