Children who often catch colds in childhood have twice as many colds after school as children who occasionally catch colds in childhood, while cells of children with high susceptibility produce lower concentrations of antiviral compounds when dealing with cold viruses. From the perspective of traditional Chinese medicine, people with weak constitution are not healthy enough to resist external evils, so they are prone to catch a cold.

2) Air pollution

When there is fog, the chances of children's respiratory tract infection will greatly increase. Because viruses and bacteria can "ride" particles into our respiratory tract for infection.

3) Kindergarten and public places

Compared with home, although there are more viruses and bacteria in kindergartens and public places, children will have enough natural immunity when they go to primary school; Children who stay at home in their early years are less likely to be infected, so their immunity is not so strong, and they will be easily infected at school.

4) Breastfeeding

Newborns will get temporary immunity from their mothers. In the first four months of life, breast-fed babies are less likely to get respiratory infections than those who drink formula milk powder.

5) Sleep quality

People who sleep less than 7 hours a night are three times more likely to catch a cold than those who sleep more than 8 hours a night, and the proportion is even as high as five times for people with poor sleep quality.

6) Chronic stress

In the current educational system environment, parents take their children to various remedial classes. People with high stress are more susceptible to infection than people with low stress. The greater the stress, the more serious the cold symptoms.

7) Asthma and allergies

Children with asthma and allergic rhinitis are more prone to respiratory tract infections, and the symptoms are much more serious than ordinary people.

8) food accumulation

Susceptible children with recurrent respiratory tract infections often have the problem of food accumulation in the spleen and stomach, and it is very easy to get sick when encountering exogenous pathogens.
