The change of seasons is also the time when children are most likely to catch a cold. Although the cold is not a major disease, but improper care, recurring colds, not only make children suffer, but also the parents of sick children will be annoyed, and even inattentive, sick children may also suffer from bronchitis, pneumonia and other diseases. 1, the causes of recurrent colds 1, lack of exercise: children usually rarely participate in outdoor activities, and lack of necessary exercise children, physical condition is often poor. 2.Lack of nutrition: Children who lack balanced nutrition will lack both vitamins and trace elements. Children with calcium deficiency can easily catch a cold because these children do not have enough protein in their bodies, so they form fewer antibodies. Children with calcium deficiency often lack vitamin D, and vitamin D deficiency can affect the development of the child’s respiratory function. Deficiencies of other trace elements, such as iron and zinc, can affect children’s resistance. And children who lack the necessary vitamins are definitely weak in resistance. 3, air pollution: If someone in the family smokes, children often suffer the most harm. 4.Oral diseases: children have chronic lesions in the mouth, such as chronic rhinitis, sinusitis, dental caries, etc. 5, temperature differences: the change of seasons, when it is cold and hot, will make the child extremely uncomfortable. 6, contact infection: In general, children who are prone to colds should try to avoid going to crowded public places because, there are complicated people and cross-infection can easily occur, and children can easily be infected if they are not careful. Thus, it seems that to prevent recurrent respiratory infections in children, what parents need to do is not to buy some resistance-enhancing drugs for their children, but more importantly to take good care of them and change some bad habits. Second, the 9 measures to prevent colds 1, sports: parents should encourage their children to participate in more outdoor sports, sports energy efficiency to enhance the child’s resistance, in this point the role of sports than taking resistance-enhancing drugs more practical, more obvious. 2, clothing: the change of seasons, the temperature difference is relatively large, therefore, some parents worry about the child freezing, the child is overdressed, the results of this practice often make the child lose the ability to adapt to climate change at the same time, the clothes are too thick, and children often sweat, wet clothes, which leads to children’s resistance is weakened. 3, breakfast: it is important to eat a good breakfast, because it can make the child’s body produce enough heat to increase the child’s resistance and ability to resist the cold. 4, hygiene: to train children to develop the habit of washing their hands before meals, after the toilet. 5, ventilation: children’s rooms must be open windows to ventilate, parents should not be afraid that children will catch a cold if they blow, in fact, the foul air in the closed room is more detrimental to the health of children. 6, isolation: If someone in the family has a cold, should avoid contact with the child, so that the child is not infected. 7, after the cold, after the heat measures: cold children are very easy to catch a cold, then parents should do is immediately let the child go to a warm place to stay a while, and can give hot soup and hot milk. After the child is heated and sweats wet clothes, he should change dry clothes in time otherwise, after sweating wet clothes, he is more likely to catch a cold due to lower body temperature. 8, cross-infection: If a child in kindergarten has a cold, attention should be paid to isolation and prevention, and the necessary disinfection, ventilation, sun bedding and other treatment in addition, do not take the child to a crowded public places, and do not take the child to other people’s homes to avoid infection. 9. Actively treat respiratory diseases: Children suffering from chronic upper respiratory diseases such as tonsillitis, bronchitis and rhinitis are more prone to colds, so parents should take their children to the hospital for active and thorough treatment of these diseases. To avoid recurrent colds in children, it is imperative to actively do the above preventive work. Third, the child repeatedly cold, parents how to care 1, rest: increase the rest time, to ensure that the child has sufficient sleep time, in order to play a role in enhancing the child’s ability to resist disease. 2.Observation of body temperature: If the child’s body temperature exceeds 38.5 degrees Celsius, it means the child has a fever and should be immediately cooled by physical cooling (warm water bath) or medication (preferably under the guidance of a doctor). 3, diet: children with colds often have a poor appetite, so parents can arrange to eat when the body temperature is close to normal after the fever subsides, and give children some light, easy-to-digest food. 4. Hydration: Especially when the fever is high, you should eat more to replenish the loss of water. 5, clothing and bedding should be appropriate: do not wear too much when the child has a high fever, cover too much, because, on the one hand, it is not easy to dissipate heat, so that the body temperature rises, on the other hand, the child will sweat too much, resulting in water loss. The correct approach is not too much clothing when fever, sleep should take off some clothes to avoid getting cold after waking up, the cover can be slightly more than usual, but in time after sweating should reduce some and timely replacement of sweaty clothes. 6.Keep the stool open: Keep the stool open is good for the child’s body temperature to return to normal If the child is constipated, parents can use the open road to relieve. 7, cough: children with colds often do not rest well because of coughing, in addition to taking medication on time, sleep with the child’s pillow cushioned higher, in a semi-recumbent position, which can reduce the respiratory secretions on the throat stimulation. Fourth, how to improve children’s immunity 1, pay attention to the child’s hot and cold, do not wear too hot, to allow him to have a proper cold exercise do not only think about the child cold, but more importantly, at any time to pay attention to not let the child heat up. Some children have been wearing a lot, is winter, is also sweaty clothes all day, all day long wearing sweaty underwear, how he will not catch a cold. 2, the activity after the fever to be timely loose clothes, do not sweat wet clothes. Parenting requirements: Children should be taught to dress and undress themselves before they go to kindergarten at the age of 3. If sweat wet clothes, should be replaced in a timely manner dry underwear, do not let children wear sweat wet underwear all day. Children under three years old, because the body temperature regulation function is not yet sound, their body temperature regulation is completely with the change of the environment temperature and change, hot will sweat and achieve the purpose of cooling. Therefore, children sweat a lot, completely wear hot caused by the vast majority of children are not because of disease and sweating people after sweating, epidermal pore stretching, more likely to have a chance to catch a cold, some children say that they can not see the wind, see the wind after easy to catch a cold, is the reason. If you do this often, your resistance will be significantly reduced. 3, if there is a cold, as early as possible to give some medicine treatment, do not delay the disease. Chinese pediatrics believes that: children are easy to develop and change rapidly, and the results of taking medicine an hour earlier and an hour later after a child has a cold are completely different. Parents who have been in contact with children for a long time should learn to observe whether their children have abnormalities of colds, and should make timely treatment when they find any abnormalities. 4, there is a disease to be cured at once, do not stop halfway. When a child has a fever of more than 39℃, the temperature should be lowered to below 38 degrees within 2 hours. A sustained temperature of more than 39℃ for more than 2 hours will cause damage to brain cells and affect the intelligence of the child. Some children have swollen tonsils or cough (bronchitis) after a cold, which is not cured at once, resulting in a cold that first manifests as swollen tonsils or cough in the future, and is difficult to cure completely, turning into chronic tonsillitis and chronic bronchitis over time. There are two possibilities: one is that the child is often sick and not easily cured, easily damaging the resistance; is often medicated, in the child’s body, there is an increase in the resistance of bacteria to drugs, the effect of medication gradually weakened. In this case, in order to cure children’s diseases, the use of antibiotics, only constantly upgrade to be effective, as the saying goes, children with drugs planted roots is so. 5, balanced diet, strengthen nutrition, enhance physical fitness. The human body has seven essential nutrients, namely water, protein, fat, carbohydrates, trace elements, vitamins, dietary fiber. The nutritionist proposed “comprehensive nutrition, reasonable ratio, balanced diet. The idea of a balanced diet is well reflected in the “one vegetable and one bean, one egg and some meat, grains and cereals to eat enough”, and also to quit the bad habit of children eating snacks at will, snacks are harmful, many parents understand, do not give only highly nutritious refined food for the sake of children, that will also appear high Nutritional malnutrition. 6, to train children to do things on their own, to have relatively independent good living and eating habits. Only when he grasps when it is cold to add clothes and when it is hot to reduce clothes, and dresses and undresses himself, he can grasp the hot and cold by himself and reduce the number of colds. Only when he eats by himself, he will be interested in eating and will eat more and better, and will have the nutrition needed to ensure growth and development. Parents should not always think that their children are small and do everything for them, but should start educating them from a young age, the earlier the better.
