1. The diet should be more nutritious. Eat more fruits and vegetables, such as apples, pears, oranges, bananas, cabbages and cucumbers. These foods can not only prevent winter fires, but also supplement enough vitamins to improve immunity and resistance.
2. In addition to diet, you can also start with warmth. Wear more clothes, wash your hands frequently and wear a mask when you go out. At home, we should not neglect to keep warm. At the same time, we should always clean and keep our home clean. Without harmful bacteria, we will naturally catch fewer colds.
In addition to the above two methods, I think we can eat a small amount of vitamin tablets, such as vitamin C and vitamin B, which can be directly absorbed by people and can also play a certain role. The effect of food supplement is better than that of food supplement. After all, it is a concentrated vitamin.
