1. On the premise of fine weather in winter, please be sure to open the window for ventilation twice every morning and evening for about 30 minutes each time. Ensure indoor air circulation and reduce the proliferation of bacteria in the air.

2. Children's resistance is gradually improved in physical exercise. When children exercise outdoors, their bodies are often stimulated by cold, which can enhance their resistance to common winter diseases such as colds and tracheitis.

3, exercise should pay attention to children should not wear too thick, too bloated, so as not to hinder the movement of the body, increase the burden on the body, and even sweat too much, but lead to a cold.

4. Teach children not to breathe through the mouth, but to breathe through the nasal cavity or nose and mouth to reduce the adverse stimulation of cold air on the respiratory tract and avoid the inflammation of the upper respiratory tract caused by cold air stimulation.

5. Add clothes to your children in time, and stop pursuing "autumn freezing". However, we should pay attention to the right amount of clothes. Children generally wear one more dress than adults.

6. Clothes that are not worn for a long time can easily cause skin allergies, redness, itching and other symptoms. I suggest you take out your winter clothes, wash them and dry them first to eliminate allergic factors.

7. Winter is cold and dry, and children's skin is prone to dryness and itching. After washing your face, you should apply moisturizing cream to your child's face and hands in time, which can effectively moisturize, moderately lock water and relieve dryness.
