Generally, babies from 6 months to 6 years old are prone to catch a cold (upper respiratory tract infection). Children's recurrent respiratory infections, referred to as "recurrent children", refer to children with weak constitution who have recurrent respiratory infections such as cold, fever, cough, runny nose and sore throat for a long time. This is mainly related to children's low immune function, malnutrition or unreasonable, inhalation of smoke, dust, insects and mites. So, what should parents do in the face of such a weak "feeling"? It is a common problem for many parents why children are prone to catch a cold during the period of weak constitution. This is because the child's own resistance is weak at this stage. Of course, compared with some children, every child is born with no resistance to germs, so when he comes into contact with germs, he is easily infected, but he will be immune the next time he encounters the same kind of germs after infection, so this is why adults catch fewer colds than children. Adults are immune to more germs, but now there are more mutated germs than before, so there are the following points to enhance children's resistance: First, the baby's resistance will get better with age; Second, pay attention to nutritional balance in peacetime. If you want to improve your baby's immunity, please refuse to give your baby refined processed food with high oil and sugar. 1. Eat more natural foods, vegetables and fruits rich in vitamins and minerals. 2. Grain is the staple food of human beings. When adding non-staple food after 4 months, rice flour and wheat flour were first tried. After weaning, the alternative food is also cereal. Whole grains contain germ and polysaccharide, and are rich in vitamins B and E. These antioxidants can enhance immunity and strengthen the function of immune cells. 3. Five servings of fruits and vegetables a day is not only the creed of adult diet, but also suitable for promoting to young children. Such as lycopene, carotene, rich in vitamins C and E, etc. Fiber can prevent constipation and provide a good absorption environment for intestinal patency. Fructooligosaccharides in fruits help the growth of beneficial bacteria in the intestine, just like laying an immune carpet on the small intestine and large intestine. If children don't like vegetables, they can chop them up and mix them with grain or meat to make meatballs, jiaozi or wonton, which is easy to accept. 4. Infants and young children are in the period of rapid growth of body and rapid development of cranial nerves, and the demand for protein and calcium is quite high. Therefore, dairy products are the best source of nutrition for infants. Yogurt is a kind of dairy product, which can give consideration to nutrition and improve intestinal environment. Very suitable for children's needs, children can only drink after one year old. 5. What is the most important part of the human body? Not hard bones, but soft water. Compared with adults, babies have higher body surface area and more water evaporation and loss, so they need to replenish more water. Sufficient water, vigorous metabolism, and naturally improved immunity. 6, in addition, don't let the baby partial eclipse and lead to malnutrition. Balanced and high-quality nutrition can build a baby's high-quality immunity and easily stay away from germs. Third, take part in outdoor sports, which is the best way to prevent respiratory tract infection. Children should be allowed to go outdoors often, bask in the sun and breathe fresh air. Fourth, pay attention to cold and warm at ordinary times. Fifth, you can go to the hospital to check whether your baby's immune function is up to standard. If it is not up to standard, the doctor will use drugs to adjust it. If it is only adjustment, it is still recommended to use Chinese medicine to adjust. Western medicine is harmful to children. Sixth, parents must be careful not to let the baby catch a cold repeatedly, which greatly reduces the baby's resistance. Drugs (especially antibiotics) can also damage the baby's resistance, so that the baby can go to public places less.
