What causes children to always catch a cold?

If a child always catches a cold, then you need to pay attention to find out the cause. For example, if the child lacks exercise for a long time and has poor immunity, he or she will catch a cold. You also need to consider whether it is caused by nutritional deficiencies, especially deficiencies in trace elements can easily lead to colds.

1. Lack of exercise

Children rarely participate in outdoor activities and those who lack necessary exercise tend to be in poor physical condition.

2. Lack of nutrition

Children who are calcium deficient are prone to catching colds because they lack protein in their bodies and therefore form fewer antibodies. Children who are calcium deficient often lack vitamin D, and insufficient vitamin D can affect the development of children's respiratory function.

In addition, the lack of trace elements, such as iron and zinc, will affect children's resistance.

3. Air pollution

If someone in the home smokes, children are often the most vulnerable.

4. Oral diseases

The child has chronic lesions in the mouth, such as chronic rhinitis, sinusitis, dental caries, etc.

5. Temperature difference

When the seasons change, the weather becomes hot and cold, which makes children extremely uncomfortable.

6. Contact infection

Generally, children who are prone to catching colds should try to avoid going to crowded public places, because there are complex personnel and cross infection is easy to occur, and children can be easily infected if they are not careful.

From this, it can be seen that to prevent children from recurrent respiratory tract infections, what parents need to do is not to buy some immunity-enhancing drugs for their children, but more importantly, to do a good job of care and change some bad living habits.
