Some children have low immunity and poor physical fitness when they are very young. Many parents are extremely worried and choose to buy some drugs to enhance their children's immunity without understanding how low it is. In fact, this is not good for children! So, what is the normal range of a child's immune deficiency? Below, the editor will provide a detailed answer for everyone!
The range of low immunity in children
A baby before the age of half: "A newborn calf is not afraid of tigers", has acquired innate immunity from its mother, so mothers don't have to worry too much. Half year old to 1.5 year old: The baby's innate immunity is gradually depleting; From 1.5 to 2 years old: At this age, the baby has regained immunity, but the growth rate is not satisfactory; 3-year-old baby: The acquired immunity against bacteria and viruses reaches 90% of that of adults. From half a year old to three years old is the most vulnerable stage of the baby's immune system, and during this stage, it is necessary to strengthen the baby's immune system.
What causes children to have a weakened immune system
1. Environmental factors: Dust, sulfur dioxide concentration, noise, radiation, as well as food and water pollution in the air are the main culprits that damage and reduce the immune system of babies. Long term exposure to polluted environments can have an impact on a baby's immunity. In addition, babies who have just entered kindergarten may not be able to adapt quickly psychologically due to sudden changes in the environment, and their resistance may decrease. In addition, the collective environment of kindergarten can also easily affect the baby's immunity.
2. Nutritional deficiency: Nutrition is the material basis for maintaining normal immune function and health in the human body. Overeating, picky eating, and dieting can cause nutritional imbalance in the body, leading to impaired synthesis of immune substances and subsequently causing a decline in immunity and disease.
In fact, parents don't have to worry about children with low immunity, because as they grow older, their immunity naturally improves. However, if a child's immunity is too low, it is necessary to go to the hospital for a check-up because the body is easily infected with viruses and other problems. It is still necessary to go to the hospital for a check-up.
