What to do if the child has no resistance

It is inevitable that babies will get sick during their growth. However, children's illness is the most troublesome for parents. Some children seem to have poor natural resistance and are easily infected with germs and get sick. However, some babies have better resistance and get sick less often. In fact, this situation is generally a manifestation of poor resistance of babies. What should we do if children have no resistance?

What is resistance

Resistance refers to the division of labor and close cooperation among various systems of the human body under the control of the central nervous system to ensure the normal progress of human life activities. The immune system is a very important component. The main function of the immune system is to defend against the invasion of external pathogenic microorganisms, which cause various diseases. In fact, the human body's defense ability is resistance.

Symptoms of poor baby resistance

There are two main sources of immunity. One is that after getting sick, the human body produces special antibodies to fight against the pathogen. When the pathogen invades again, the antibodies can combine with white blood cells to kill the pathogen, thus preventing the disease. This immunity can last for a long time (such as measles antibodies) or be temporary (such as cold antibodies). After getting a vaccination, the body will actively produce immunity after being stimulated, and this immunity is generally lifelong.

The second source of immunity is "passive". For example, newborns (babies within one month after birth) receive many antibodies from their mothers and develop immunity; another example is that after the injection of immunoglobulin (antibodies against a certain disease), it may have a short-term inhibitory effect on certain rare diseases.

If your baby has the following symptoms, you may consider whether he has low immunity: irregular bowel movements and prone to diarrhea; prone to illness when seasons change; wounds that are difficult to heal and prone to infection; babies living in a group are often infected with diseases by children around them; and their baby catches colds frequently, more than three times a year.

How to improve baby's immunity?

1. Provide adequate nutrition

Babies are in a continuous growth and development stage and require relatively more nutrients. However, since the digestive function is not fully mature and the diet is often monotonous, nutrient deficiencies are easy to occur; if there is insufficient nutrition, the resistance will be relatively poor. According to current research, mild (or subclinical) vitamin A and vitamin C deficiency is a common cause of recurrent respiratory tract infections in children. Therefore, eating more fresh colorful vegetables and fruits rich in vitamin C (the beta-carotene contained in them can be converted into vitamin A in the body) or supplementing with some multivitamin preparations can indeed effectively increase the baby's resistance.

2. Do some physical exercise

This is an important aspect of strengthening your physical fitness. Exercise should start from an early age. After a baby is one month old, he can lie outside for a while in the summer and open the window to breathe fresh air in the winter. Don't wear too many clothes. Train your baby to adapt to colder environments from an early age so that he will not easily catch a cold when the climate changes. Outdoor activities can not only enable the skin to synthesize vitamin D, thereby promoting calcium absorption, but also have a good effect on the development of muscles, bones, respiratory, circulatory systems and the metabolism of the whole body. Regular exercise can also increase your appetite. If your baby takes in enough nutrients, his physical fitness will be enhanced and his resistance will be significantly increased.

3. Drink more boiled water to keep the mucous membrane moist

Drinking plenty of water can keep the mucous membrane moist, which becomes an important line of defense against bacteria. Let your child carry a water bottle when going to kindergarten or going out so that he can drink whenever he is thirsty. Remember to drink plain water instead of sugary drinks. No need to be too clean - form immune memory; the immune system can form immune memory against infectious pathogens, and if encountered again, it can quickly eliminate them. If your home is too clean, your child will not have the opportunity to produce antibodies through infection, and their resistance will be weakened, which may lead to allergies and autoimmune disorders. Normally, just use ordinary soap and water to achieve the purpose of cleaning, and do not use disinfectant every day.
