How to prevent colds in winter

To prevent colds in winter, I think we can do the following.

1. First of all, you must wear a mask when you go out and go to crowded places less, which can greatly prevent the risk of catching a cold brought by the outside world. Then when you get home, you should wash your hands frequently, open the window for ventilation, help the air circulation at home, and reduce the harm of pathogenic bacteria to your body.

In daily life, we must pay attention to cold and warmth. It is very cold in winter. Generally, it will be a few degrees below zero in the south and colder in the north. It may be tens of degrees below zero in winter. We must wear sweaters, down jackets and other warm clothes.

In addition to the above points, it is more important to exercise regularly if possible, which can increase your resistance and prevent colds.
