Recurrent cold causes

1, lack of exercise
Children very rarely participate in outdoor activities, while the lack of necessary training, children are often relatively poor physical condition.

2, lack of nutrition
Calcium deficiency in children are easy flu, because these children lack the body protein, so the formation of antibodies is also less. Calcium deficiency in children is often a lack of vitamin D, lack of vitamin D would affect the respiratory function of a child's development.
In addition, the lack of trace elements such as iron, zinc and so on will affect the child's resistance force.
3, air pollution
If people smoking at home, children are often the greatest danger collected.
4, oral disease
Children with chronic oral lesions, such as chronic rhinitis, sinusitis, dental caries and so on.
5, temperature
When the turn of the season, when hot or cold will cause the child very suited.
6, contact infection
General, easily a child suffering from a cold should avoid crowded public places to go, because, where the personnel situation is complicated, easily cross-infection occurred, believe the children would easily be infected.
View of this, to prevent recurrent respiratory tract infections in children, parents need to do is not to buy the children to enhance resistance to drugs, more importantly, doing care work and change some bad habits.

Anti-child food cold

Breast-feeding is not only a breast physical and intellectual development of children the best food. But also the effectiveness of the prevention of influenza. Studies have shown that breast milk contains protective effect of respiratory tract mucosa several immunoglobulins, particularly secretory lgA most lgM and lgG the other two have a lot of content. In addition, there is a certain amount of inhibition of influenza virus, such as the lysozyme \ lactoferrin, macrophages and other immune factors. Therefore, breast-feeding babies than non-breastfeeding children cold incidence is much lower, which is why we need to promote breastfeeding as an important reason.
Food rich in vitamin A scientists abuse, lack of winter and spring Va in children susceptible to respiratory tract infection is a major incentive. Researchers in Indonesia died of the 140 cases of child study concluded that: In the cold and other respiratory infections high season, to an increased number of children Va rich food, will enable the child mortality rate by three quarters. Va American scientists believe that by enhancing the body immune system is to obtain the effect of anti-infective. In addition, Va can reduce the risk of measles and mortality. Va-rich food are carrots, amaranth, spinach, pumpkin, red and yellow fruits, animal liver, milk, etc., if necessary, Va oral preparations, infant 1,500 ~ 3,000 units per day, a day older children 3 , 000 ~ 5,000 units.
Zinc-rich food studies have shown that Zinc is a lot of virus's "nemesis." U.S. scientists using zinc inhibition of HIV has been initial success, Tianjin Medical College of Experts of influenza treatment with zinc has been made with good results. High incidence of flu season in the multi-eat foods rich in zinc help the body resist common cold virus, the mechanism is: ⑴ Zinc can directly inhibit the proliferation of viruses; ⑵ zinc enhance cellular immune function, especially the function of phagocytes. Meat, seafood and poultry are the richest zinc. In addition, a variety of beans, nuts, seeds and a variety of categories is zinc good food choices.
Food rich in vitamin C in foods can Vc contained cystine reduction of proteins into cysteine, homocysteine is an important human immune army members - the material necessary for the synthesis of antibodies, they are indirectly promoting Vc antibody synthesis, and enhance the role of immunization. Vc trial abroad was 3 grams per day of oral prevention of colds, also proves that some children eat proper foods rich in Vc is effective prevention. All kinds of fresh fruits and green leafy vegetables are good foods to add Vc.
Iron-rich food study found that lack of iron the body can be caused by T-lymphocytes and B-lymphocytes to generate damage, the quantity and quality of performance for the decline in phagocytic cell function weakened, reducing the number of natural killer cells and other immune function changes. The iron-rich food the body can not conducive to the above-mentioned changes in disease resistance have been corrected, return to normal, to the purpose to combat influenza infection. Such foods are animal blood, milk, eggs, spinach, meat and so on. But too much should not be blindly partial eclipse, in particular, is an iron-fortified foods, first, to avoid undermining the balance between trace elements and lower zinc and copper absorption rate; Second, too much iron storage in the body, may have contribute to bacterial growth and the proliferation of defects.
