As autumn approaches, the autumn breeze will rise, and children with asthma will have recurrent attacks, holding their breath, coughing and wheezing. Why do asthma attacks occur in autumn? How to detect and prevent asthma? These are big questions for children and parents. 1.Why is asthma more frequent in autumn? (1) The airways of children with asthma are susceptible to increased airway reactivity due to changes in ambient temperature, as the temperature in autumn is influenced by climate change and the temperature difference between morning and evening varies greatly. It has been found that the incidence of asthma is highest when the average temperature is 21℃. Nowadays, the cold dew has passed, the temperature drops significantly in the morning and evening, and the temperature difference between day and night is large, which can cause vasoconstriction in the respiratory mucosa and reduce local resistance, so bacteria and viruses can easily take advantage of the situation. Since children’s resistance is poorer than that of adults, they are more likely to suffer from respiratory infections that lead to recurrent asthma attacks. (2) The increase of pollen from seeds and plants in autumn causes allergy and leads to recurrent asthma attacks. It is well known that asthma is mainly due to the exposure of the body to certain allergens, such as dust mites, pollen, bacteria, and camptothecin, which produce anti-allergen antibodies that bind mainly to the receptors on some major cells that cause asthma attacks and adsorb to the surface of the airway mucosa, and when exposed to such allergens again, the abnormal or overpowering immune response produced by the body will cause increased airway inflammation, airway spasm, and Asthma then occurs. Therefore, if a child with allergies is exposed to or inhales allergens such as pollen, dust mites, molds, etc., asthma is easily triggered. In addition, it has been found that patients with allergies in their families have a higher likelihood of asthma in their children. Many seeds and plant pollen float in the wind in the fall and can cause asthma attacks when inhaled by children with allergies. (3) Allergic children are more susceptible to respiratory infections: autumn is also a high season for respiratory infections, and if you do not pay attention to adding clothes, it is easy to cause respiratory infections after getting cold. Among the pathogens of respiratory infections, most of them are mainly viral infections, and respiratory viral infections are closely related to the development of asthma, which is also an important reason for the increase of asthma. In addition, autumn is a time when summer is just over and children with allergies return to school from the end of summer with a changed environment and stress, which also tends to increase the occurrence of recurrent respiratory infections. And respiratory infections are the most common cause of triggering asthma in children. 2.What are the main ways to prevent asthma in children in autumn? (1) Avoid triggering factors: The attack of bronchial asthma is closely related to the allergens, and after the attack, the triggering factors should be carefully searched and analyzed to avoid them as much as possible. One is allergic substances, such as pollen, dust, fur, milk, eggs, fish, shrimp, crabs, paints, drugs, etc. Each patient has different allergens, some are one or two, some as many as dozens; the other is physical and mental state, such as bad mood, overwork, inhalation of cold air, etc., or even see the substances that used to cause asthma, can cause mental stimulation and Asthma can also occur reflexively; asthma attacks can also occur when meeting examinations; it is found that children with allergies tend to have lower immune function, and once they accidentally catch a cold and encounter allergens, they often have cold symptoms accompanied by wheezing. Therefore, children with allergies need to pay attention to avoid cross-infection and, more importantly, to improve their immune function. (2) Strengthen physical exercise: Many children with bronchial asthma are in a nervous state psychologically because they are worried about asthma attacks after getting cold or cold, and they have concerns about physical exercise, resulting in a decrease in physical fitness and an increase in morbidity. In fact, physical exercise is very beneficial to children with asthma, and parents can choose the appropriate form of exercise according to the physical condition of their children. For example, insist on swimming or washing the face and feet with cold water or even washing and scrubbing the whole body from summer. Through these exercises, the child’s ability to resist the cold can be enhanced, and the immune function of the body can be improved, thus strengthening the body and reducing the occurrence of asthma. (3) Pay attention to diet: Children with asthma should usually pay attention to eating more high-protein foods, such as lean meat, eggs, poultry, soybeans and soybean products, etc., to increase calories and improve the ability to resist disease. Also eat more foods containing vitamin A, B, C, D and calcium: foods containing vitamin A have the function of moistening the lungs and protecting the airways, such as egg yolk, cod liver oil, carrots, leeks, pumpkin, almonds, etc.; foods containing vitamin C have the function of anti-inflammatory and anti-cold, such as dates, grapefruit, tomatoes, green peppers, etc.; foods containing calcium can enhance the anti-allergic ability of the airways, such as pork bones, green vegetables, tofu, sesame paste, etc. Avoid overly sweet and salty foods during asthma attacks. The stimulation of overly sweet and salty foods can strengthen the bronchial response and aggravate symptoms such as coughing, shortness of breath and palpitations, thus making it difficult to control asthma. Also pay attention to eating less cold drinks, carbonated beverages, fried foods and other stimulating foods. In conclusion, parents of children with asthma should, first of all, increase or decrease their children’s clothes according to the climate change, cover them well at night to prevent getting cold and avoid catching a cold; help their children to do some moderate physical exercise in general to enhance their resistance to disease; use some preventive drugs, such as adrenal glucocorticoid aerosol, as early as possible when there is a sudden change in climate with light cough and chest tightness: as the disease is prone to recurrent attacks, it gives the children Psychologically, it can have a negative impact on the child. Parents should actively help their children to build up confidence in overcoming the disease, and show extra care and consideration to make them emotionally stable and happy. 3.Why do children get asthma too? Asthma is a chronic inflammatory disease of the airways that involves both genetic and environmental factors, with genetic factors being the endogenous cause and environmental factors being the exogenous cause. Children, like adults, also live in a social environment, and as long as children carrying the asthma gene repeatedly encounter the stimulation of triggering factors in the external environment, they are likely to develop asthma. In addition, the immune function of the body during childhood is relatively low, especially the defense mechanism of the respiratory tract is not as good as that of adults, and it is easy to have recurrent respiratory infections, so it is more likely to have recurrent asthma attacks. 4.How can I find out that my child is suffering from asthma? Asthma attacks can be divided into aura, exacerbation, remission and severe exacerbation periods. During the aura period, which is the early stage of asthma attack, the child can show chest tightness, coughing, itchy nose, sneezing and so on. During the exacerbation period, children may have sudden chest tightness or choking sensation, long expiration and short inhalation, and whistling sound in the throat; during the remission period, children may have occasional chest tightness, but it may be aggravated during activities or coughing obviously; during severe asthma attack, children may have severe cough, sputum, chest tightness, shortness of breath, shortness of breath, and in severe cases, they need to be resuscitated. Asthma attacks are often seasonal, with more attacks in spring and autumn. Based on the history of recurrent asthma attacks, dyspnea with croup during attacks, which can be relieved by taking bronchial antispasmodics, etc., children with asthma are not difficult to detect. 5. I heard that asthma will heal itself when children grow up and it doesn’t matter if they are treated or not. Is this correct? The incidence of asthma decreases with age, so folk believe that asthma will heal itself without treatment. However, it is important to note that some children with asthma have a poor prognosis if they have frequent attacks. It is generally expected that attacks will continue into adulthood by age 14. If a child with genetic allergies. Frequent and severe asthma attacks suggest that the attacks will continue and the prognosis is poor; furthermore, repeated asthma attacks will affect lung function and their prognosis will be poor. Therefore, we hope to fully control asthma attacks in children before puberty, and strive to achieve complete control of asthma and clinical cure before the arrival of puberty. 6.What is the general approach to treat children’s asthma? There are two stages and four methods to treat asthma in children. The two stages are: to relieve the disease during the attack period, bronchodilators can be used to release the spasm of bronchial smooth muscle, while glucocorticoids are used to eliminate airway inflammation; during the remission period, medication should be continued according to the results of the disease assessment to reduce recurrent attacks, preferably no attacks at all, to achieve full control of the disease. The four methods are to first avoid allergen exposure, while enhancing education of patients and relatives, then standardize the use of medications according to the condition to keep airway inflammation at a minimum, and to require combined desensitization therapy for children with more severe conditions or unsatisfactory treatment results. If the four methods are applied in combination, the results are often more satisfactory.
